Mascara

I'm working in mascara formulation. I use Beeswax, CMC, xanthan gum, Argan oil, Cacao batter, Bentonite, PVP, EDTA, Stearic acid, Triethanolamine, FeO, Den Ethanol, water and a bit preservative.

Is use of ACRYLATES necessary? What is their impact in Formula?
I want have a professional formula As far as possible. what is important in mascara formula and I haven't?

Thank you in advance for your answers

    if you mean "acrylates copolymer", it's used for waterproofing / volumising / smudging reduction
    the most widely available polymers of this kind are the Daitosol series from Daito Kasei, which are designed for use in colour cosmetics

  • 1) All those oils aren’t necessary 
    2) Iron oxide won’t give you jet black color. You need carbon black
    3) A bit preservative is a bad idea. You need to think through your preservation system very very carefully when it comes to anything that’s in close contact with eyes. Mascara is a product prone to contamination.

    Thanks about your advice. Is diminished of 'acrylates copolymer' true?

    Thanks a lot
    Which oils aren't necessary?
    Is carbon black safe for use in cosmetics?
    I use From sodium benzoate and potassium sorbate, 0.2% each of them. Is it enough?

    That is clearly not enough.  Those are not enough vs pseudomonads that can cause very serious eye infections.  Please look at labels of major marketers e.g. Estee Lauder, Cover Girl

    Hi
    I don't want use of Paraben derivatives.
    Benzyl Alcohol is so Irritant.
    Can you help me about this issue?

    Use phenoxyethanol.

    Should I use of it alone? Can I use it with other preservatives like sodium benzoate and potassium sorbate?
    How percentage is enough?

    7-8
    I use TEA for adjust it
    What other pHs can be suitable for it?
  • AbdullahAbdullah Member
    Use it with another Preservative. 
    At that pH you may use it with Ethylhexylglycerin or caprylyl Glycol or Paraben or caprylhydroxamic acid. 
    I don't know other preservatives that can be combined with phenoxyethanol and effective at high pH.

    7-8 - the organic acids are +/- useless.   Unless you can qualify your preservative system - esp. to ISO 11930 critetia - please do not attempt a mascarsa.
