What is Phenethyl Alcohol?

Phenethyl alcohol, chemically known as 2-phenylethanol, is an aromatic primary alcohol featuring a benzene ring attached to an ethanol group. Naturally present in rose oil, honey, and some fruits, it is synthetically manufactured for broader purity and consistency in cosmetics. This colorless liquid with a rosy, floral aroma belongs to the fragrance and preservation category in skincare formulations. It functions by imparting sensory appeal through its scent, while its antimicrobial action disrupts fungal cell membranes, aiding in product stability. As a solvent, it enhances ingredient solubility, particularly for oils in water-based systems like lotions and cleansers. Commonly found in concentrations under 1%, it supports clear, stable emulsions without altering texture, making it suitable for daily-use creams, shampoos, and serums across various skin types.
