Hydroxyacetophenone
What is Hydroxyacetophenone?
Hydroxyacetophenone is a synthetic organic compound classified as a phenolic ketone, specifically 1-(4-hydroxyphenyl)ethan-1-one. Produced through chemical synthesis, it serves primarily as a multifunctional ingredient in cosmetic products such as creams, serums, toners, and cleansers. In formulations, it acts as a preservative by interfering with microbial cell membranes, thereby inhibiting the proliferation of bacteria, fungi, and yeasts. Its antioxidant capabilities stem from the phenolic hydroxyl group, which donates electrons to neutralize reactive oxygen species and prevent ingredient degradation. Additionally, it functions as a skin conditioner, helping to maintain skin barrier integrity without promoting pore clogging. This makes it suitable for a wide range of water-based and emulsion-type cosmetics, enhancing product stability and shelf life.
