Alkylresorcinols widely occur in nature and are known to be biodegradable and present in significant amounts in the bran fractions of wheat, rye and other cereals. Works as an antiseptic, and can therefore be found in soaps, skin cleaners, and throat lozenges. Hexylresorcinol is widely used as an antihelmintic, meaning you could potentially use throat lozenges to get rid of parasitic worms if they were growing inside you. Hexylresorcinol can also be used to prevent shrimp black spot (melanosis), an unappealing surface discoloration of shrimp caused by the enzymatic production of pigmented compounds, as well as the browning and decay of fresh-cut mangoes and apples.
