Title:
SINGLE OR MULTI-PHASE DETERGENT FORMS WITH SPECIAL BLEACH ACTIVATORS
Document Type and Number:
WIPO Patent Application WO2000060035
Kind Code:
A3
Abstract:
The invention relates to detergent forms which have an excellent bleaching capacity, even after long storage periods; and short decomposition times, even with high degrees of hardness. The inventive detergent forms contain a bleach activator in the form of cationic nitriles of formula (I) wherein R<1> represents -H, -CH3, a C2-24-alkyl or alkenyl radical, a substituted C2-24- alkyl or alkenyl radical with at least one substituent from the group -C1, -Br, -OH, -NH2, -CN, an alkyl or alkenylaryl radical with a C1-24-alkyl group; or a substituted alkyl- or alkenylaryl radical with a C1-24-alkyl group and at least one other substituent on the aromatic ring, R<2> and R<3> are selected independently of each other from the following: -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)nH with n =1, 2, 3, 4, 5 or 6 and X is an anion, the pH-value of the 1 wt. % aqueous solution of the form or the phase containing the nitrile quat being less than 10.
