"Finally, a paraben and formaldehyde-free preservative! Optiphen is a unique liquid preservative formulation which consists of phenoxyethanol and an emollient base. For use in a variety of formulas such as aqueous, anhydrous and emulsion products. Optiphen is a clear liquid preservative that can be easily added directly to the formulation during pre- or post-emulsification, at or below 80°C. Optiphen has no pH restrictions in formulating, and is compatible with most ingredients used in the personal care industry.
