Dihydrocapsaicin is a capsaicinoid and analog and congener of capsaicin in chili peppers (Capsicum). Like capsaicin, it is an irritant. Dihydrocapsaicin accounts for about 22% of the total capsaicinoid mixture[2] and has the same pungency as capsaicin.[1] Pure dihydrocapsaicin is a lipophilic colorless odorless crystalline to waxy compound. It is soluble in dimethyl sulfoxide and 100% ethanol.
