    I know @Microformulation does a lot of natural formulating consulting so he may be able to help you.

    @Belassi - You’re mostly right.  But it’s ingredients 1% or less don’t have to be listed in order.  So if Ingredient A was in the formula at 1% and Ingredient B was in the formula at 0.5%, it would be perfectly fine to list it a B,A or A,B.  However, if Ingredient A was used at 1.1% then it would have to be A,B

    Good stuff.  

    I think the key point in the article is the second one.  Have a Marketing message and plan.  If you can’t figure out why someone would want to buy your product instead of a competitor’s then you don’t have much of a product.
    He did miss the Distribution part.  You can have the greatest product in the world but if you don’t have a plan for distribution you won’t sell much.

    Heard of it.  I don’t know where you can get it though.  Try searching Citrus Aurantium Dulcis

    @nasrins - yes, quaterniums can be either.  Quaternium 80 is a conditioner.  Quaternium 15 is a preservative.

    @milliachemist - I haven’t heard that.  I’m under the impression (from reading the PCPC guidelines to the INCI dictionary) that the numbers are just order of registration.

    Quaternium and Polyquaternium refer to molecules that have a + charged Nitrogen ion.  Otherwise the molecules are not related.  So just because something is a Quaternium or Polyquaternium doesn’t mean they are going to function similarly.  The numbers also don’t mean much of anything except the order in which they were registered.

    Also measure and keep track of the levels you use so you can reproduce your work.  You can also try to guess at the percentages that you used but weighing things out is better.

    It’s also helpful to know what else is in your formula.  But if you need a number….try 5% and go up or down from there.

    September 16, 2014 at 3:29 pm in reply to: Sea Salt Hair Spray (Rockaway Salt Spray by R+Co)

    It’s a little easier if you eliminate the ingredients that don’t matter…

    WATER, ALCOHOL, MAGNESIUM SULFATE, PPG-26-BUTETH-26, PVP, PEG-40 HYDROGENATED CASTOR OIL, PEG-12 DIMETHICONE, CITRIC ACID, PHENOXYETHANOL, POTASSIUM SORBATE, CHLORPHENESIN, BENZOIC ACID, SORBIC ACID, FRAGRANCE

    You could evaporate off the water and alcohol to get an approximate concentration for those.  I would guess the following formula (but this is just an off-the-cuff guess).

    Water = ~85%
    Alcohol = 10%
    Magnesium Sulfate = 1.5%
    PPG-26 Buteth-26  = 1%
    PVP = 1%
    Hydrogenated castor oil = 0.5%
    PEG 12 Dimethicone = 0.5%
    Citric acid = adjust to pH of the system (probably 0.2%)
    Fragrance = 0.5% or less
    Preservative system (PHENOXYETHANOL, POTASSIUM SORBATE, CHLORPHENESIN, BENZOIC ACID, SORBIC ACID) = less than 1%

    This doesn’t seem like much of a study.  It doesn’t appear they ran any kind of experiment beyond taking the pH of shampoos.  I’m left wondering…

    1.  How did they determine that “alkaline pH increases friction between fibers”?
    2.  How did they demonstrate that “lower pH of shampoos may cause less frizzing for generating less negative static electricity on the fiber surface”?
    In my estimation this is a junk study that doesn’t prove much of anything.  In my opinion based on years of work with shampoo formulations, you would be hard pressed to demonstrate any significant difference between a shampoo with a pH of 5 versus one with a pH of 7.

    September 15, 2014 at 8:54 am in reply to: Percent

    @Kfox - Just multiply the size of the batch by the % and divide by 100.

    500 g batch, 5% of the ingredient = 5*500/100 = 25g
    The Khan Academy is an excellent source too.

    Hello @beautysci,

    You can join the course now if you like.  We’re going to have an “official” role out at the start of October.

    Perhaps for your diet a natural antioxidant is better but for stabilizing a cosmetic formulation I would think a synthetic antioxidant is more reliable.

    What are you using the antioxidant for in the formulation?

    @JCG - If your chemist is going to take care of safety and efficacy testing too then the price doesn’t sound too unreasonable.  It’s still high but that stuff gets expensive when done right.

    But here’s something to read about your fears of someone stealing your idea.

    Basically, people who are formulating chemists are in the business of creating formulas.  They are not in the business of marketing cosmetic products.  There is a significant difference.  Your fears of someone stealing your idea are holding you back and I encourage you to just tell people your idea.  

    I personally do not waste energy on NDAs and trade secrets and patents because in the cosmetic industry they are worthless.  Once your product is on the market anyone can easily copy it.  If your formula is your point of differentiation then you are in trouble.

    When marketing a cosmetic product you should put your energy into building your brand.  Yes, you want to have excellent working formulas that look and feel cool but the thing that will sell your product is your branding and marketing.

    Usually when there isn’t a product like yours on the market there is a good reason for that.  Either the technology doesn’t exist to create a functional product or no one has figured out how to market the idea.  The fact that there isn’t a product like it on the market is actually a bad thing in my opinion.  That means there is no market for it.  You will have to build the market.  The best product ideas are unique twists on products that already exist.

    Most of the hair conditioners I made were single pot creations.  Our production people liked it that way.  Things like fatty alcohols, Glyceryl Stearate, and silicones don’t have to be mixed in separate phases.  At least not in the formulas produced for VO5 and Tresemme back in the day.

    Some people get royalties but you can also find cosmetic chemists who will work for a flat fee without royalties.

    August 26, 2014 at 12:25 pm in reply to: Oils - what do the specifications mean to me?

    It doesn’t answer all your questions but here is some information you might find helpful about certificate of analysis tests.

    Free Fatty Acid content is the amount of fatty acids in the formula that have been liberated from the natural occurring triglyceride molecule.  See this for more information.  http://www.hrpub.org/download/201310/cme.2013.010306.pdf

    Right.  If you make the SPF claim, you have to demonstrate that it’s true via testing.  Pointing regulators to the BASF formula is not adequate for proof.

    @rawmaterialgirl - yes, oil can also reduce the viscosity.  It happens with Fragrance oils all the time.
