    I Thought the “How to Knock off Any Cosmetic Product” report was quite informative and useful for those not so familiar with cosmetic formulations. For those of us who have been around for a long time it was refreshing to see that
    there is an honest and informed approach to such matters in this current world of misinformation.

    Thank you this is not for me but i think it’s very good for a person who are interested in the cosmetics,
    i am a chemist i love formulating perfume .i have master degree in chemical engineering , One of my goals is to discover ingredients that are capable of catching perfumers’ and brands’ interest, while at the same time fulfilling health and safety criteria and the capacity for long-term supply. All of that within the context of reconciling producers and consumers
    Natural living has always suited me and the influences that are part of my life have evolved and strengthened with time. Even when I was little, I was always intrigued by nature, I believe that is what has driven and lead me to live the lifestyle which I enjoy so much today.

    A well thought-out and comprehensible guide to duplicating a product which will be particularly useful to small manufacturers without a background in Chemistry. More of a problem for us, particularly those not US-based is sourcing the materials we need for dupeing.

    I thought the information was very useful. For someone who is newer to cosmetic formulation and wanting to make products that stand out, it is a good idea to first understand what makes other products on the market so unique (from a formulators point of view not just from commercial claims). I think this information only adds creativity to the formulation and development process.

    Over the years I have knocked off several National Brand Equivalent formulas that wound up as generic products at national pharmacy chains (lip balms, analgesic creams, etc.). Whenever I read articles about Cosmetic Chemistry, I like to think I’m modest enough to admit that I will ALWAYS learn something new and thats what I love about this job, I’m always learning! With regard to Perry Romanowski’s “How to Knock-Off a Cosmetic Formula” I learned several useful nuggets of knowledge to apply to my everyday work. I found the report to be systematic in its approach to cosmetic formula duplication and very comprehensive in its scope. Where was this useful tool 10 years ago when i was just starting out?!

    critic says:

    I think the whole idea preposterous. Cosmetics is about innovation, and that is what people should learn: critical thinking, and then creative thinking.
    And I doubt one can learn cosmetic formulation on the internet; it requires patience, observation, curiosity, but not this kind of approach.
    I think there are already too many “knock-off” products on the market, many of the infringing patents, lacking claim substantiation data, safety data, but just out to make a buck by comparing ingredient listings, forgetting that the INCI names are, with few exceptions, much too vague to help truly identify the exact substance(s) used. this is particularly true for plant extracts which are just listed as the name of the plant, but give no indication of how the extract is obtained (water or solvent extraction, or other methods), how much of the “extract” (powder, hydroglycolic solution, essential oil) is really used; many biotech products and protein hydrolysates face the same characterization problem.
    This confusing situation certainly does nothing to make a better reputation for the cosmetic market!
    Training people is fine, and doing it for free is a debatable choice, but I don’t think this approach is the right one.

    TGrier says:

    I think you provide a good overview of the observations, resources, and methods used to create a knock-off. Any time an individual provides insight into the actual work that they do (in this case we’re talking about formulation chemistry) you provide hands on insight that is helpful to someone. I found it useful in giving me a new approach to my at home creations and it even kindled my creativity because it gave me new ideas of how to craft something original. ~Thanks

    Jerome says:

    I had been using a similar approach and some of his detailed suggestions have been helpful. There were some very practical suggestions/instructions that I wish I had come to realize before. However,there are some complex balances that are needed to put a stable formulation together and one suppliers raw is not the same as the next, I did not get that from the article. It is far more complicated than the article implies.

    Nancy Piscatello says:

    Thanks for the report, it made me realize I wasn’t on the wrong track by trying to, at first, copy another successful formula. It was most informative on the steps to copy a formula, but there are so many variables, that things can become unclear. I’m working on a lip gloss and found that my formula was coming out too oily no matter how many times I copied this other companies formula and no matter how many variables I altered. If you upped the oils to soften the formula: too oily; if you upped the waxes: it became too solid and not as softly “gloppy”, if you will.
    So, even though the report answered the basic “how to copy” and made me realize that copying is the surest way to find your own formula, it still left me with so many more questions.

    Mark Fuller says:

    I enjoyed the report. It was really encapsulated the process.
    People may feel that they never need to duplicate cosmetics. As a Consultant Formulator I am often approached to do a knock-off or duplicate a standard. Oftentimes it is by the owner of the Product who no longer has access to their Formulas. A little known fact is oftentimes Contract Manufacturers will charge a large fee to purchase the Formulas. In some cases it is easier to have the product duplicated by a third party. This can present the client with an opportunity to refine or improve the product.

    chemicalmatt says:

    Regarding “How to Duplicate a Cosmetic Product”, a fine work Perry.
    Some corrections:
    Iodopropynyl Butylcarbamate is an (antifungal) preservative, not a “solvent”
    Tetrasodium EDTA is a chelating agent/preservative, not an “adjustment”
    Some suggestions:
    In Step 3, pages 13 and 14, the ingredient breakdown by the 1% Rule. It may be advisable not to de-emphasize the <1% content. In the example given, the Polyquaternium-10 level can make a marked difference in outcome if it is at 1.00%w/w or at 0.10% w/w in this body wash. Perhaps it would be wiser, on page 14, to state:
    The formulator can later prioritize the <1.00% ingredients by function. This will provide insight into their concentrations, since the “less than 1.00%” may be listed in any order on the LOI. Some general rules of thumb can be applied (and this can be extrapolated much more):
    0.50 — 1.00% conditioning agents, sensory modifiers, rheology modifiers, emollient oils, surfactants
    0.20 — 0.60% fragrance, preservatives, adjusters, proteins
    <0.20% extracts, exotics, color stabilizers, colorants
    On Page 16, Step 5 “Analyze the Formula” can be much more explicit. Given that the example is an easy one (body wash), mention should be made about emulsion analysis of creams and lotions (which includes hair conditioners!). E.g.
    Determine if the product is a water/oil or oil/water emulsion. Most are the latter. If unsure, test by measuring conductance (in milliohms) relative to water. W/O emulsions will have poor conductance. A simple test is to add a dollop of the product into a glass of water and observe its behavior; or add a dollop of water to a small amount of the product. O/W emulsions will dissociate in water unevenly and incompletely, as an oil slick at first. W/O emulsions will dissociate evenly. If you add water to them, they usually just thin down a little, without dissociation. Also, look at the first two or three ingredients that you’ve identified as “surfactants” and look up their HLB values or their function from literature. If the primary surfactant (first or only one listed) possesses low HLB value, the product is likely W/O.
    Regardless of the emulsion type, you will need to rough calculate the “oil load”, or the nature of the product’s disperse phase for O/W emulsions, or continuous phase for W/O ones. Though often recognized as the amount of oil payload being delivered by the formula, this can be more thoughtfully considered as the ratio of oil payload to emulsifiers. Sensory feel will lead the way here (see Step 2!), once you’ve determined the solids level. A short playtime on the skin with little observed emolliency lends itself to a low oil load (1.5:1 or less). Exceptions to this rule abound, notably when cyclomethicone or isoparaffin is involved. Creams and lotions exhibiting a richer feel will generally have a higher oil load (2:1 or more). Some creams and lotions will feel very heavy, even greasy, leading you to deduce a high oil load, which is a typical of some “skin butters”. Some W/O emulsions carry an oil load of 20:1!
    Likewise, this step needs to better emphasize water content, often the most crucial step in saving time in duplication of water-based formulae. If the reader is a novice, you might flush out the method more. You may want to add:
    If you have access to an accurate balance, then weigh out 10.00 grams of the benchmark product onto a tared Petri dish, watch glass, or even a ceramic cup saucer. Place this in a convection oven, like you have at home, for 2 hours at 125C or 250F (no more!). Record the net weight then return it to the oven for another hour to note any significant loss in mass. The total loss in mass comprises mostly water, but may include alcohol, cyclomethicone, fragrance and other volatile components, so compare to the ingredient listing sequence to further deduce the water concentration. The mass of the residue after drying divided by the original sample mass will be your % total solids, which will be a most useful value in determining concentrations of the ingredients and of the oil load of lotions and creams.

    I thought the report was great and your reminder to read it timely as I was just asked to dupe a foot cream. I also appreciated chemicalmatt’s addendum as this particular cream seems to have a great number of ingredients below the 1% line and the ‘general rule of thumb’ stated will help to make some sense out of all of them. Also, I did look this up in patents and it was not there. However, this companies preservation system was, so that will help too.

    This is a perfect overview of the process. Food for thought for those who are reluctant to give away their formulation to EU-safety evaluation! The chemical analysis of target products will hardly be necessary for experienced formulators. The same applies to all the claim support equipment mentioned in “Specialized tests”. My suggestion is to elaborate a little on the stability testing additional to the reference given and to add safety evaluation principles. Thanks!

    An important part that is missing is pricing out the formulation. At least a “ballpark” figure on cost of the formulation (per lb, per kilo, per ounce) without packaging should be given. There might be active or other ingredients that are too costly for the customer, especially is the

    This is an excellent book which is very easy to understand and practical. This book tells you how to make a product step by step and I believe this book will benefit many people.
    I do have a suggestion. Mining patents is an excellent idea, but for many people it is a big challenge. If the author can have a similar book with examples to teach people how to do it, I will definitely look forward to reading it very much.

    hi – Loved the book – it was simplified and easy to understand. Regarding the fragrance, what if you don’t want a fragrance added to the product? Some people are allergic and prefer fragrance-free products. Would you use some kind of masking agent to cover an unpleasant-smelling product? Thank you. Lisa

    I found this guide, “How to Knock off Any Cosmetic Product”, a useful and general source for cosmetic formula replication. Being a analytical chemist with formulations experience I would say that this guide should be mandatory for all of those looking to create their own cosmetic formulas. This approach make the most sense for those with a limited budget and with little experience in the cosmetics, formulations, or chemistry as there is a myriad of poor and simply incorrect information available on the subjects.

One, what do the numbers after the ingredients listing of many products mean (ex. ) and two how can you search for a specific product’s patent using the United States Patent Office site or any other site?

    I just read your little book on how to imitate any form of a cosmetic product.
    This is really interesting and it’s what I wanted to learn for some time. It is clear, precise and directly usable. Thank you very much for this document.
    But in addition, I am interested in the training that you give through your website but I am in Africa where we have no broadband here as the United States. What alternatives do you suggest?
    Also for practical training, would I be able to come to work in your labs here in the U.S.?
    When I write these words, I am in your country where I could easily follow your videos.
    But, how to follow the free high speed internet?
    I am a pharmacist in the industry since1994, I think my previous experience will help me learn better. Do you believe it too?
    I want to register immediately but I await your response.

I mean you don’t really tell me fully what i am getting for my money there are no sneak previews of recipes nothing except your video, so I quickly lost interest, you need to draw people in more!

Will they provide their sample materials to an individual?

    Hi Perry,
    A great read. Some stuff I knew already, but enough tips to assist further. Last time I ripped a formula, I used Karl Fischer to determine moisture content, and using known values ( such as Carbopol 0.3% typical usage rate) and worked out the rest from there. I think a combination of what you do is fine.
    I am looking at studying cosmetic science to fill in my knowledge gaps. I typically tend to formulate capsules, softgels, tablets etc and not too much in the cosmetic field.

    Marina Giorgii says:

    The report is excellent for its purpose, and it would be useful to me if I wanted to do just that- copy other cosmetic products. But what I’m really after, for now, is the basic knowledge/tips/principles on how to mix simple, natural ingredients for my own personal use, how to make base lotions, creams and serums- and how then modify/add to them. I really never liked anything available on the market, and I’ve tried many products, some more, some less expensive. Most skin-care products contain preservatives, synthetics, and other toxic chemicals (even if some of those are proclaimed harmless), too much fillers, and not enough active ingredients. At this point, if anything seems to be even remotely suspicious, I don’t want it on my skin. That disqualifies most of the personal care products from my use. As a first step, I’d like to be able to create my own fruit acids gel/mask of any concentration/strength I desire. Second, I make my own liposomal vitamin C (for internal intake), and I’d like to incorporate it in my potions, so I need to know how to mix it with oils, for example (such as rose hip seed, my favorite), how to add other vitamins, etc. I don’t have much interest in replicating existing formulations because, as I said, I’m not impressed with them. Simply exfoliating my skin with some enzymes and glycolic acid, and following that with pure rose hip seed oil, improved my skin more already than any commercial products I tried so far. I just want to take what I’m doing now one step further.

    I am just starting my own cosmetics line and found that I was already doing many of the things that the free report said to do. I am a Chemical Technologist and in my opinion the report on “How to Knock Off Any Cosmetic Product” was accurate and concise. Even if you don’t have any training or experience in chemistry you should be able to follow the method in that document and create decent products. In fact, even if you’re just trying to make your own stuff without necessarily copying anybody you still need to do the same things. How can you possibly begin to make anything if you don’t even know what’s in it? It’s a great little document, especially if you don’t know chemistry- it is written so that anyone can understand it and apply it and achieve success. Happy formulating, everybody!

    I found the report to be a fairly good introduction for some, though I had already worked out, through simple logical deduction, more or less the same processes on my own.

    It is a great resource for those who want to do that, but I am more at the level of Susan Nichols series of eBooks at the intro level. I am at the friends and family level and being retired, have no interest in the liability exposure at my age. Thanks to your journal reference, I now have quite a bit of good (and somewhat contradictory) info about the possibilities of oil and butter “essential” ingredients actually getting to where they need to be to affect the effects as the claimants would like to be true.

    Dear Perry,
    I found the introductory of a cosmetic formula an extremely informative guide for the beginner and would recommend to any ‘novice’ or newcomer to this industry.
    As an experienced formulator – this is exactly how I learned my craft starting initially in aerosols and progressing into other areas of fragrance and
    toiletries – I started in 1982 under the guidance of a pioneering aerosol chemist and equally apt in toiletries – so I had a good grounding [I digress].
    My only real comment is that there are a few salient points I think, that could be added but that apart a very good pointer, well thought out and
    well structured – keep up the good work!

    Dear Perry,
    As an experienced formulator – I started in 1982 my mentor and guide being a pioneering Aerosol Chemist [also adept in toiletries] and your guide
    is exactly the way I learned my skills [I had to start with 1950’s formulations to understand the basics] before progressing to modern formulations.
    I would thoroughly recommend this guide to ‘novices’ and newcomers alike.
    My only comment is that there are few anomalies that need ‘tweaking’ – nothing serious and few additions that may have been overlooked and I would recommend – purely from a personal viewpoint.
    That aside a very good and informative introduction to any newcomer – keep up the good work!

    But I have an additional question, please, can I replace the salt sodium chloride and ammonium chloride salt in the same proportion?
    Can I use magnesium sulphate with Lauryl sulfonic acid to get the shampoo does not tear the eyes? And if so; does add salt (sodium or ammonium) or rest on it and realized viscosity too?
    Finally Can I use tylose the viscosity to raise? When can I hold added without that happening during the conglomerate added?
    Then what is the damage to the hair of this added?
    Thanks for your attention

      AndyH says:

      Hi Ghassan,
      In answer to your question, I would suggest the following;-
      1. Use Ammonium Laureth Sulfate 70% as your main active ingredient (6 – 8%)
      2. Buffer with Ammonium Salts (phosphates) (0.5-1.0%).
      3. Use Cocamidoproyl Betain approx. 5 – 7%
      4. Use Cocamide DEA approx.0.8% (keep minimal)
      5. Thicken with 0.7-1.0% of Ammonium Sulphate dissolved in 5% of the batch water.
      6. Other ingredients to suit your intended shampoo.
      You may need to ‘juggle around’ but this does work.
      Hope this helps,

        Ghassan says:

        Thank you very much for this information, but I think that the percentage of (Cocamidoproyl Betain approx. 5 — 7%) very high , Because it is what I think of the Quartet amines that may lead to dry hair .

        • Avatar
          AndyH says:

          In response to your comment regarding Cocamidopropyl Betain – this is an amphoteric/zwitterion surfactant and helps to reduce the irritant effect of anionic surfactants (i.e. your primary active).
          The level of 5.00 – 7.00% (corresponding to 1.50 – 2.10%) is by no means excessive as you are reducing the Cocamide DEA, which
          is more of an irritant and has a greater drying effect.
          To further combat drying/irritation, it is useful to add PEG-7 Glyceryl Cocoate at 0.50 – 1.00% which also gives a degree of moisturisation and results in an even milder product.

    If you allow I have a question about the installation of cosmetics:
    At any stage I can modify the pH of the cream during manufacturing, by citric acid or lactic acid, without separation occurs between the oil and water phases?

    Gill says:

    Overall I thought a helpful report. I was pleased that it reinforced what I already knew, which was reassuring- while also offering some new ideas.
    One area I have some questions on though- As you state: Ingredient listing is meant to be in order down to 1% and then 1%, and below that, in any order.
    However when an ingredient is a blend of several components/INCI labelled compounds, often the supplier /manufacturer does not give the relative proportions of those individual ingredients. So while the formulator might add the blend in at say 3% the individual components of the blend wont be their at 3%. In this situation what is the formulator meant to do when listing the ingredients?
    In (most?) instances I suspect that the formulator just lists the ingredients details of the ingredients sequentially and as it is very difficult to tell what groups of ingredients represent blends from the ingredient listing, this could be misleading. I am aware of some ingredient blends that are sold which contain more than of 6 listed ingredients . Any thoughts on what to do to identify and deal with these situations would be appreciated.

    • Avatar
      Perry Romanowski says:

      You should really never be in a situation where you work with a supplier who won’t tell you the relative proportions of the ingredients in a mix. At the every least they need to tell you what the INCI label name would be given your formula.
      In truth, if the ingredient is used at less than 1% then it doesn’t matter. And that is 1% active. Most ingredients that are a mix of 6 or more ingredients are typically mostly solvent.

Its funny when I think about it – I never thought I or anyone else would be able to make a cosmetic product- I guess I always thought robots made them or something! haha You know I always read the ingredients before I purchase a product – a lot of them look so complex and technical (this coming from someone with a background in Mech engineering..) – it never occurred to me that the public had access to these ingredients and that I could actually mix them together to make something that worked.

    • Avatar
      AndyH says:

      Hi Deborah,
      Again I find myself responding (apologies for my enthusiasm having being in the industry for so long!).It can depend on your location geographically to find a perfume house to cater for your needs -depending scale, quantity, price and availability.
      There are numerous suppliers locally or through agents who can satisfy demands from minimum quantities to bulk – depending on
      your manufacturing requirements.
      As regards to distillation (not as straight f0rward as you may think) there are smaller suppliers who specialise – but you will need to
      spend time sourcing these reliable specialists – although major fragrance houses will oblige [quantity viable].
      What I would advise is to source your favourite botanicals from a reliable supplier (of which there are many) and would suggest essential
      oils rather than absolutes due to the cost of such!
      If you require botanical extracts – a rather different ‘kettle of fish’ again there are many reputable suppliers who can supply ‘regular’,
      or ‘organic’ versions depending on your requirements.
      Good luck!

Patents are supposed to disclose but how much to they protect? If a formulation is as easy as you say to knock off, then trade secrets are a waste of time.

    Hello Perry !
    I’d like to thank you for the e-book “How to Knock off Any Cosmetic Product” that you sent and give my feedback about it. It is a very useful e-book ! I’m from Brazil and here is kind of dificult to find books about this subject, it is really inspiring to me and I’m happy to know that the work that I used to do here is almost the same that some cosmetic chemists do in U.S. (as you showed in the book)! One new thing that I learned from the book as the “1% rule” I did not know that . So thank you !

    Dear Perry , Have been in the Essential Oil and Spice and Botanical extracts industry and always had interest in Cosmetic formulations. Have been interacting with a lot of Cosmetic formulators – especially on the Fragrance and in the development of Active Botanical Ingredients and related product development. Even though , have been doing a few things what has been suggested in the 10 step system without actually knowing about it formally , your Report has given me a fresh insight and would definitely help me in approaching new tasks with a much greater clarity and discipline ……. Incidentally , I happen to interact with a lot of Food Processing companies who are trying to developing products in line with the Market leaders ……..Feel , the 10 step system would apply and hold good even for Food products too…………….

    “How to Duplicate Any Cosmetic” was fun to read. I am currently looking to further my career as a chemist. I want to learn about all the raw materials and how they interact during manufacturing of cosmetics. Just making the cosmetics isn’t enough, I want to understand exactly what is going on! I found a place to start looking.

    I found the report very informative and clear. For me, a beginner in the area, every trustfull and practical, piece of information that comes to my hand, is of great utility. This report was quite practical and was direct to the point. Easy to read, simple and short as the information should be. The subject itself was very useful, because for the beginers like me, we suspect that the number of copies or near copies should be big in the market, but we always fear to be inspired in competitors, and to fear to do benchmark is an error. It helped to clarify how to behave in this market in the commercal level.

    I really enjoyed “How to Knock off Any Cosmetic Product”. The report let me know that I am on the right track and pointed out some things which I did not know. It gave me a step by step process on how to get my product more in line with what I had envisioned and the report showed me how to look at other products to determine the reason behind the ingredients listed.
    What I am currently trying to do is make my own base. By following the precepts listed in the report, I should be able to get to my destination faster than I had previously anticipated. I’m also learning a bit more about chemistry and it is a world full of excitement and adventure.

    I’ve been developing some unique anti-itch lotions during the past many months, and might have made faster progress if I had read your Knock-Off book earlier, but I wasn’t trying to match an existing product. I have improved such lotions considerably. I question whether your suggestion on page 20 to add salt to adjust viscosity, when gellants are much more effective but take some learning on how to use them. I’ll pass the notes onto a new assistant.

    Alisa says:

    The booklet fed into my “mad scientist” side. I have been doing many of those things since I was 13. I would go to the cosmetic counters and ask to look at the products while I study the ingredients list. Every time I read about a new skincare or haircare product in Vogue or Allure, I immediately research the ingredient list and try to figure out how I could do a better formulation. I thought I was the only one that occupied herself by being such a sleuth. I am always curious what makes a product work or not work and what would make it better. I did not learn so much as I felt emboldened and encouraged to continually try to take the best products in the industry, make them better by tailoring them to my needs, getting rid of the ingredients that don’t really add anything, and adding ingredients that would have a better synergy … I love finding out that I am not alone in my favorite hobby.

    Hi Perry,
    Very useful information. I have always been interested in doing reverse engineering on some products I’ve used that proved to be very effective. My idea is to understand the composition take out the bad stuff and improve the formulation for added benefits.
    I am curious though, are these companies completely honest in listing all their ingredients when it can be easily copied. Where is the competitive advantage in that case.

      Perry Romanowski says:

      Yes, they list their ingredients. In the cosmetic industry, it is marketing that sells most products not the performance of the products. Just because you can copy someone’s formula does not mean that you will have a successful product line. People buy cosmetics because of good marketing.
