Aromatic Preservative Booster (Phenethyl Alcohol)

Phenethyl Alcohol is an aromatic alcohol used in cosmetic formulations for its antimicrobial-supportive properties, preservative-boosting function, and refined sensory profile. It helps enhance product protection by contributing activity against certain microorganisms, often used in combination with other preservatives to improve overall system efficacy. In addition to its functional role, Phenethyl Alcohol can contribute a subtle, rose-like aromatic note and help solubilize fragrance components, supporting a clean, elegant formula character. Commonly found in serums, creams, lotions, toners, mists, cleansers, and hair-care products, it is typically used at low levels and formulated with attention to pH and skin tolerance, as higher concentrations may increase the risk of sensitivity in reactive skin types.
