4-Hydroxyacetophenone is a multifunctional aromatic ketone used primarily as a preservative booster and soothing agent in cosmetic and personal care formulations. It enhances the efficacy of traditional preservatives, allowing for reduced usage levels while maintaining antimicrobial performance. Additionally, it exhibits antioxidant and anti-inflammatory properties, contributing to improved skin tolerance and overall formulation mildness. 4-Hydroxyacetophenone is effective across a wide pH range (typically pH 4–8) and is valued for its non-sensitizing profile and formulation versatility.
