Classification Code of 4-Hexylresorcinol (CAS NO.136-77-6): Anthelmintic; Anthelmintics; Anti-Infective Agents; Antiparasitic Agents; Drug / Therapeutic Agent; Mutation data; Reproductive Effect; Skin / Eye Irritant; Tumor data

 4-Hexylresorcinol (CAS NO.136-77-6) is used as an antiseptic, commonly employed in a dilution of 1:1000. It commonly can be used  on small skin infections, or as an ingredient in throat lozenges. It has the same lightening effect as 2% hydroquinone over an 8 week period in vivo studies conducted on Synovea HR 4-Hexylresorcinol.

In the manutacture of 4-Hexylresorcinol (CAS NO.136-77-6), resorcinol and caproic acid are heated with a condensing agent, such as zinc chloride, and the intermediate ketone derivative is formed, which is purified by vacuum distillation. After reduction with zinc amalgam and hydrochloric acid, impure 4-Hexylresorcinol is formed, which can be purified by vacuum distillation.

Reported in EPA TSCA Inventory.

A poison by ingestion and intraperitoneal routes. Moderately toxic by subcutaneous route. Experimental reproductive effects. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. An eye irritant. Concentrated solutions can cause burns on the skin and mucous membranes in humans. An anthelmintic and topical antiseptic. When heated to decomposition it emits acrid smoke and fumes.
