    Abstract: The invention relates to a detergent and cleaning agent formulation, containing, besides other usual components, a bleaching system based on hydrogen peroxide, peroxo compounds and/or peracids, as well as a mixture of (A) largely biodegradable aliphatic or alicyclic amine with 1-12 C-atoms, which can, in addition, carry hydroxyl groups, and (B) complexing agents having a complexing effect on heavy metals, whereby the weight ratio of A:B ranges from 20:1, in particular from 1:5 to 5:1. The above mixture of amines (A) and complexing agents (B) has a stabilizing effect on the bleaching system.

    Abstract: Use of amines (I) is claimed as bleaching enhancers for textile detergents. (I) have pKa > (A-1) (preferably pKa > (A+0.5)). A = pH of the textile washing composition which contains 1 wt.% wash liquor. especially at least 0.5 above the pH. Also claimed are bleaching agents and textile detergents containing (A) 0.5-40 wt.% peroxide and/or percarboxylic acid bleach; (B) 0-20 wt.% bleach activator; and (C) 0.1-1 (especially 0.25-0.45) wt.% of a sec. amine of formula R NH-R (II), (III) or (IV). R = 6-14C hydrocarbyl or 6-14C hydroxyhydrocarbyl; and R = 1-5C hydrocarbyl, preferably Me; p, q = 0-4; X = 1-8C alkylene (optionally interrupted by O, S, O-C(O)-, NR or -NR-C(O)-) or 2-8C alkenylene; R = 1-8C alkyl; Y = as for X or bond, O, S, -O-C(O)-, or -NR-C(O)-; or when p+q
