Abstract: Enol esters having formula R1-COO-CR4:CR2R3 (I) (where R1 is H, Me, Et or Ph ; R2 is H or 1-5C alkyl ; R3 is H or 1-5 C alkyl and R4 is H, 1-4C alkyl or Ph ; R2 and R3 are opt. identical and R3 and R4 together can be components of anisocyclic 4-7C ring) are used as cold bleach activators for detergent- and cleansing compsns. contg. active-O-supplying materials as bleaching agents. The double bond adjacent the ester gp. increases enol ester activation. (I) are as active as tetraacetyl-ethylene diamine and tetraacetyl glycol uril, without the hazard of forming decomposition prods. which could cause water eutrophy. In partic. suitable (I), R1 is Me ; R2 is H or Me ; R3 is H or 1-5C alkyl ; R4 is H, Me or Ph and R3 and R4 together form a 5-6C isocyclic ring. (I) are esp. isopropenyl acetate, cyclopentenyl- and cyclohexenyl acetate. Quantity of (I) can be 1-20 (2-10) wt.% w.r.t. total cleansing or detergent compsn. (I) can be added in bulk or adsorbed on 3-dimensionally crosslinked macromolecular water-insol. inorganic cpds. contg. SiO- and/or AlO- cpds., e.g. zeolites.
