Hydroxyacetophenone
A mild antioxidant and preservative-booster used to stabilize formulas and support gentler preservative systems.
What it does
Hydroxyacetophenone has antioxidant activity and helps boost the performance of a product's preservative system, letting formulators use lower levels of stronger preservatives. It is often described as soothing in marketing, but its dependable, evidence-backed role is formulation stability. It works in the background to keep a product fresh and is generally well tolerated.
