Detergent formed bodies, which exhibit good hardness and good disintegration properties, include cationic nitrile compounds as bleach activators

摘要

Cationic nitrile compounds of formula (I) are used to improve the hardness and disintegration properties of detergent formed bodies. Detergent formed bodies, which are composed of compressed, particulate detergent, comprise: (a) bleach; (b) one or more bleach activators, including a cationic nitrile compound of formula R2-N(R1)(R3)-CH2-CN X- (I); and optionally (c) other detergent components. R1 = H, Me, 2-24C alkyl or 2-24C alkenyl (optionally substituted by Cl, Br, OH, NH2 or CN); or 1-24C alkyl-aryl or 2-24C alkenyl-aryl (optionally ring substituted by further substituents); R2, R3 = CH2CN, Me, Et, CH2CH2Me, CHMe2, CH2OH, CH2CH2OH, CH(OH-Me, CH2CH2CH2OH, CH2CH(OH)Me, CH(OH)CH2Me or (CH2CH2O)nH; n = 1, 2, 3, 4, 5 or 6; X = an anion.
