Phenoxyethanol

Description

Phenoxyethanol is a widely used synthetic preservative in cosmetics and personal care products. This colorless, oily liquid is prized for its ability to inhibit the growth of bacteria, yeasts, and molds, thus extending product shelf life and maintaining formula integrity. Chemically, it is an ether of phenol and ethylene glycol, with the molecular formula C8H10O2.

Typically used at concentrations between 0.5% and 1%, phenoxyethanol is effective against a broad spectrum of microorganisms. It is particularly valued for its stability across a wide pH range and compatibility with most cosmetic ingredients. This versatility makes it suitable for various formulations, including creams, lotions, and liquid products.

While generally considered safe for use in cosmetics by regulatory bodies, some individuals may experience skin irritation or allergic reactions. It's important to note that phenoxyethanol is not a natural ingredient, which may be a consideration for consumers seeking all-natural products. Despite this, its efficacy and relatively low incidence of adverse reactions have made it a popular choice among formulators, especially as an alternative to parabens in preservative systems.
