    About the only natural ingredient that is going to work with non-ionics is xanthan gum.  For a better skin sensorial, you might try Solagum:  Acacia Gum and Xanthan Gum (Seppic).

    @raiyana:

    Your best approach is to avoid Glycerin (and Panthenol) completely is water-based toner-type products.  It will be sticky even at 1% Glycerin if your product format is a Toner.

    @cheekychooky:

    No worries … as Perry mentioned, when you read something posted by someone you have never communicated with before, it oftentimes can be interpreted with different intonation in the reader’s mind than intended in the writer’s mind … just always use INCI for your ingredients and that makes it easier for everyone to give you advice.

    I just love it when people post formulas using product trade names as opposed to INCI names for some ingredients …. just who is it that you think has time to look up product trade names to answer your question?

    Thank you very much! 

    aqua, glycerin, stearic acid, petrolatum, olea europaea oil, cetyl palmitate, cetyl alcohol, alcohol, sumatra-benzoe, parfum, methylparaben.

    what is an emulfisier in this product?

    I would suspect that they used a small amount of Sodium Hydroxide to get the Stearic Acid to form Sodium Stearate which would function as the emulsifier.  Otherwise, the formula appears to not include an emulsifier and Stearic Acid is the only obvious candidate that could function as an emulsifier, but it would require the addition of a base such as NaOH.  Otherwise, Stearic Acid, Cetyl Palmitate and Cetyl Alcohol all function as thickeners.

    Perhaps they just left NaOH off of the list of ingredients and considered it to be a processing aid.  You really don’t need both Cetyl Palmitate and Cetyl Alcohol in this formula … one of the two alone would suffice and Cetyl Palmitate would be the preferred option since it also functions as an emollient.

    @BekaS:

    Research “microemulsions” … there are a handful of emulsifiers developed specifically for this purpose.  For instance, you could try a combination of Coco-Glucoside and Glyceryl Oleate + Sucrose Stearate or as @ngarayeva001 pointed out Ppg-26-Buteth-26 (and) Peg-40 Hydrogenated Castor Oil … BASF, Evonik & Croda all off emulsifiers specifically for development of microemulsion sprays and lotions

    what can you do if live in country who evryone says my product is natural and without parbens and presevatives??

    @smok:

    The whole notion of your argument is that you think that your competitors are advertising that they do not use parabens and preservatives and you are using that as justification for saying your products are natural when you know they are not.

    Do you actually have evidence that your competitors are in fact using parabens and no preservation?

    Regardless, this is not justification in any way for your own false advertising.  In fact, it is a marketing opportunity for you to prove that you are truly natural … oh, let me correct that … you can’t claim truly natural because your products are not all natural … you just falsely advertise them as such.  Nix that idea.

    To answer your question:  Be honest in your advertising … it’s real simple

    Actually, you should not be making cosmetic products … why don’t you do the world a favor and simply stop making adulterated products and stop lying about your products.  Having integrity is quite simple … more so than being deceptive.  May your next bite of canned meat be spiked with dog shit as filler.

    And so they force us to lie to sell our products
    Because we must say our product is natural 100%

    Let me fix that for you … what you really mean to say is “I lie to sell my products by misleading consumers telling them that my products are 100% natural when I know they are not and I am forced to lie to consumers because I think other companies that I compete against also lie to consumers”

    People like you are dangerous and should not be making cosmetic products if you are knowingly selling adulterated, mislabeled products and misleading consumers.  There is no excuse for that.

    Think about the implications of your attitude next time you eat packaged food if you think lying to consumers is acceptable.

    September 25, 2019 at 3:59 pm in reply to: Hyaluronic Acid %’s

    Again, this is a play on words … they are referring to the trademark VIZ 1000 ingredient combination of which 75% of that trademarked combination of ingredients is Hyaluronic Acid.  They don’t claim how much of the VIZ 1000 complex is in the product … probably 2% or less.

    They are not claiming that the entire product contains 75% Hyaluronic Acid, only that the VIZ 1000 “complex” contains 75% HA.  It’s a play on words that can have a deceptive interpretation by consumers.

    September 24, 2019 at 12:46 pm in reply to: Do you think there is a problem with cosmetic research?

    Research is not divorced from economic constraints … either the product can make money to cover its production, sales & marketing costs and provide a profit to  pay for more research or it is not economically viable.  In fact, those economic constraints can be properly viewed as “creativity drivers” … Any idiot can develop an effective product with an unlimited research budget and no requirement for the product to be economically viable.

    Only is the world of Bernie Sanders is everything simply “Free”

    If you are in this industry you need to accept a simple fact:  No one actually needs cosmetic products … their purchase is pure discretionary.  And, that is the reason why research is used primarily to support sales activities unless you are developing new ingredients.

    @enthusiash:

    It’s basically a play on words … in the example that @JonahRay linked, they’re referring to the hyaluronic acid being 100% pure HA, but state that they are using a 1% concentration of 100% pure HA.

    Post a link to the 65% example … as @ngarayeva001 stated, depending on the molecular weight of the HA, you’ll get 2% HA max into solution.  You can get more using a super low molecular weight HA, but it’s going to be pricey.

    I’m sure your 65% example is a similar play on words.

    Yes, Sodium Phytate can function both as a chelating agent and can be used to adjust your pH up.

    If you want to adjust your pH to more acidic levels, then you’ll want to use Phytic Acid.

    This really all comes down to a matter of intellectual property and economics … unless you are an ingredient manufacturer or you have a patentable, proprietary ingredient/process, it is not economically viable, or in your business interests, to conduct extensive research on cosmetic products.  Just enough research to substantiate your marketing claims is really all that makes sense unless you have something proprietary.

    Yup, sodium phytate is what’s commonly sold as “phytic acid”.

    If I may clarify that …

    Phytic Acid and Sodium Phytate are two different ingredients.  Sodium Phytate is a white powder that has a native pH of 12 … use it to raise the pH of a formulation. 

    Phytic Acid has a native pH of 3 and you use it to lower the pH of a formula.

    Agreed … better to go overboard than not.

    Yes, the Ascorbic Acid + Sodium Benzoate argument is overblown … unless you are adding both at high temperature for extended periods of time, you simply will not reach the activation energy level to effect a reaction.  And, yes, it is done frequently.

    @DIY_Newbie

    You might be better off just using Gluconlactone, Sodium Benzoate, Calcium Gluconate … Geoguard Ultra or Gluconlactone SB instead of the individual ingredients … it’s a pre-mix preservative blend.  One ingredient instead of 3 separate ingredients.

    @usmanali:

    A shampoo is not a great format for a hair loss product since most of the “active” will simply be washed away as opposed to deposition on the scalp, hair shaft and follicle where it can actually have some effect.

    That said, perhaps caffeine, nettle extract and copper tripeptide-1.  Use the copper tripeptide-1 powder at 0.2%.

    You can even throw conditioning ingredients into the combo body wash/shampoo to eliminate a separate hair conditioning product … it won’t perform as good as a dedicated hair conditioner, but certainly would be acceptable.

    @royalbre:

    Generally, Yes, within a category.  For instance, a personal care body wash can also be used as a shampoo/body wash and hand soap or facial soap, for instance.  Personally, I only use one product for all of the above purposes because working with so many surfactants and chemicals over the years, but primarily surfactants, my skin, hands in particular, has become quite sensitized and irritates easily.  Add to that a hair conditioner and moisturizer for shaving and 3 products take care of most of my needs.

    I’ve never tried washing my dishes with it.  But, by the same token, I never wash my face, hands, hair & body with a dishwash detergent.

    An approach would be for you to offer a selection of fragrances that consumers could purchase directly from you that you know would incorporate successfully into your base cleanser formula.
