Description
4-Hydroxyacetophenone Product Overview
4-Hydroxyacetophenone (C8H8O2) is a white to off-white crystalline powder that is slightly soluble in water and dissolves in glycols and ethanol. It occurs naturally in some plants, such as spruce needles.
In addition, cosmetic formulators use it at about 0.3–0.8% as an antioxidant and soothing ingredient that boosts preservation, which helps formulate products labeled free of conventional preservatives, often with 1,2-Hexanediol or ethylhexylglycerin. Similarly, pharmaceutical producers use it as an intermediate, for example for Acetaminophen, and chemists use it for fragrances, polymers and liquid crystals.
Notably, related cosmetic ingredients in our range include D-Panthenol, Alpha Arbutin and Salicylic Acid.
