Optiphen Plus Preservative
Optiphen Plus is a top choice globally approved preservative system developed for personal care formulations where a formulator requires a paraben and formaldehyde-free preservative system.
Optiphen Plus preservative is an innovative preservative package made up of a blend of phenoxyethanol, sorbic acid and an emollient base offering effective protection against bacteria, yeast and mold growth with the added benefit of imparting emolliency with the caprylyl glycol. This combination makes Optiphen Plus a true multi-functional ingredient since the caprylyl glycol imparts good moisturizing and good after feel to products like cosmetic and skin care formulations. Plus the caprylyl glycol provides some good viscosity modification in some formulations. This combination makes Optiphen and Optiphen Plus more than just a preservative.
