phenoxyethanol

Description

Phenoxyethanol is a widely used preservative in cosmetic and personal care products. This synthetic compound, with the chemical formula C8H10O2, is a colorless oily liquid with a mild rose-like scent. Its primary function is to inhibit the growth of bacteria, yeasts, and molds, thereby extending the shelf life of various formulations.

Phenoxyethanol is effective against a broad spectrum of microorganisms and is typically used at concentrations between 0.5% and 1% in skincare products. It is particularly valued for its stability across a wide pH range and its compatibility with other cosmetic ingredients. This preservative is often chosen as an alternative to parabens due to consumer preferences.

While generally considered safe for use in cosmetics by regulatory bodies, including the FDA and European Commission, some individuals may experience skin irritation or allergic reactions. Phenoxyethanol is water-soluble and partially oil-soluble, making it versatile for use in both water-based and oil-based formulations. It is commonly found in products such as moisturizers, serums, sunscreens, and makeup. When formulating with phenoxyethanol, it is often combined with other preservatives to enhance its efficacy and provide comprehensive protection against microbial contamination.
