Optiphen™ Plus is a globally approved liquid preservative blend combining Phenoxyethanol, Caprylyl Glycol, and Sorbic Acid.

Especially effective in emulsions (like creams and lotions) and surfactant-based products (like shampoos and cleansers), it functions well at acidic pH levels and is a go-to preservative for natural and mild formulations.
