glycerin and preservatives.
I have a question regarding a pressing medium for cosmetic glitters.
I am using 90% isopropyl alcohol at 75% of the formula, glycerin at 25% of the formula then adding cap 5 at 1% of the total weight of the liquid.
Phenoxyethanol, Caprylyl Glycol, Potassium Sorbate, Hexylene Glycol. The Caprylyl and Hexylene
Is this adequate to preserve the finished product from bacteria & mold once it is mixed with cosmetic glitter and pressed?
