  Preservatives and base to use with coconut oil?

  Posted by Anonymous on September 8, 2016 at 11:29 am

  Hello
  I’m wanting to start a small business selling pressed glitters and eyeshadows.

  For the pressed glitters I’m looking at using the following ingredients - isopropyl alcohol (70%), cosmetic grade glitter, and fractionated coconut oil (as a binder instead of glycerin) and sodium benzoate and potassium sorbate as a preservative. Is this a suitable preservative to work with these ingredients?

  Would the sodium benzoate and potassium sorbate also be a suitable preservative for the pressed eyeshadows?

  Also, would sericite mica lauroyl lysine be a suitable binder to use for the pressed eyeshadows with the rest of the ingredients - fco, mica and iso alcohol, and possibly the preservative above?

  All suggestions and comments welcome

  thank you

  The suitability of a preservative can only be determined by micro challenge testing.

  The best and safest preservative to use for this is a combo of parabens and phenoxyethanol.
