A bleach composition comprising an inorganic persalt bleaching agent, a lipophile selected from flavorants, perfumes, physiological coolants, antimicrobial agents and mixtures thereof, and a dimethicone copolyol selected from alkyl- and alkoxy-dimethicone copolyols having formula (I) wherein: X is selected from hydrogen, alkyl, alkoxy and acyl groups having from about 1 to about 16 carbon atoms, Y is selected from alkyl and alkoxy groups having from about 8 to about 22 carbon atoms, n is from about 0 to about 200, m is from about 1 to about 40, q is from about 1 to about 100, the molecular weight of the residue (C.sub.2 H.sub.4 O--).sub.x (C.sub.3 H.sub.6 O--).sub.y X is from about 50 to about 2000, and x and y are such that the weight ratio of oxyethylene: oxypropylene is from about 100:0 to about 0:100. The composition provides improved lipophile and bleach stability.
