Optiphen plus
A broad-spectrum preservative system that combines the power of phenoxyethanol, caprylyl glycol, and sorbic acid to protect formulations from microbial contamination.
Optiphen Plus is a paraben-free, formaldehyde-free preservative system commonly used in cosmetic and personal care formulations. It contains a combination of phenoxyethanol, caprylyl glycol, and sorbic acid, which together offer a broad-spectrum defense against bacteria, yeast, and mold.
This preservative is effective across a wide range of pH levels (4.0–8.0) and works well in emulsions, gels, and anhydrous formulations. It provides stability and protection for water-based formulations while being gentle on the skin. Optiphen Plus is particularly valued in clean beauty formulations due to its non-toxic, non-irritating nature.
It is ideal for use in facial creams, lotions, shampoos, body washes, and other personal care products that require reliable and safe preservation.
