GENERAL DESCRIPTION

Butylated hydroxytoluene( BHT), chemically also called 2,6-di-tert-butyl-p-cresol (DBPC), obtained by alkylation of p-cresol with isobutene or by monobutylation of m,p-cresol mixtures. BHT is used as a food antioxidant much like butylated hydroxyanisole (BHA) as these phenol derivatives react with the free radicals (called free radical scavengers) can slow the rate of autoxidation that can lead to changes in the food's color and taste. It is used as an antioxidant in plastics, elastomers and petroleum (lubes, greases and waxes), practically bigger market size than food field.
