Hexylresorcinol

CAS: 136-77-6

Overview

Hexylresorcinol (CAS 136-77-6 ) is a phenolic compound used across food, cosmetic, and pharmaceutical manufacturing as an antioxidant, preservative, and UV stabilizer. Its ability to inhibit enzymatic browning and microbial activity makes it a commercially significant ingredient.

In food processing, this compound is applied to crustaceans and seafood to prevent melanosis, extending shelf life and preserving commercial appearance. Cosmetic formulators incorporate it into skin-brightening and anti-aging products.

The ingredient suppresses tyrosinase activity to reduce hyperpigmentation in various skincare applications. In pharmaceutical manufacturing, it functions as an active ingredient in antiseptic throat lozenges and topical preparations targeting minor infections.

Polymer and plastics producers also use it as a UV stabilizer and antioxidant additive to protect against photo-degradation in finished materials. This versatility ensures its demand across diverse industrial sectors and manufacturing processes.

The product is supplied as a white to off-white crystalline powder or solid. It is available in food-grade and pharmaceutical-grade specifications, with USP and BP grades commonly offered for regulated applications.

Technical-grade material is also available for industrial polymer and stabilizer end uses. Our supply chain ensures consistent quality and purity for all manufacturing requirements, meeting the rigorous demands of global chemical distribution.
