SINGLE- OR MULTI-PHASE DETERGENT TABLETS CONTAINING SPECIAL BLEACH ACTIVATORS

摘要

Detergent tablets combining high bleaching performance with short disintegration times, despite high hardness values, contain as bleach activator cationic nitrites corresponding to formula (I): (see formula I) in which R1 represents -H, -CH3, a C2-24 alkyl or alkenyl group, a substituted C2-24 alkyl or alkenyl group with at least one substituent from the group consisting of -Cl, -Br, -OH, -NH2, -CN, an alkyl or alkenyl aryl group containing a C1-24 alkyl group or a substituted alkyl or alkenyl aryl group containing a C1-24 alkyl group and at least one other substituent at the aromatic ring, R2 ad R3 independently of one another are selected from -CH2-CN, -CH3, -CH2-CH3, -CH2-CH2-CH3, -CH(CH3)-CH3, -CH2-OH, -CH2-CH2-OH, -CH(OH)-CH3, -CH2-CH2-CH2-OH, -CH2-CH(OH)-CH3, -CH(OH)-CH2-CH3, -(CH2CH2-O)n H where n = 1, 2, 3, 4, 5 or 6 and X is an anion, the pH value of a 1 % by weight aqueous solution of the tablet or the phase containing the nitriloquat being below 10.
