Enzyme stabilisers in washing or cleaning agents comprise end group capped fatty acid amide alkoxylates of formula (I): R<1>-CO-NH-(CH2)n-O-(AO)x-R<2> (I) R<1> = 5-21C alk(en)yl ; R<2> = 1-4C alkyl ; A = 2-4C alkylene ; n = 2-3 ; and x = 1-6. Also claimed are (i) detergents containing 0.1-50 wt.% (I) and 0.1-10 wt.% synthesised enzyme, (ii) mixtures comprising (A) compounds (I) and (B) fatty alcohol (poly)ether sulphates, fatty alcohol (poly)alkoxylates and/or fatty acid (poly)alkoxylates, (iii) the preparation of mixtures comprising (A) compounds (I) and (B`) fatty acid (poly)alkoxylates corresponding to (A) in which -NH- is replaced by O, (iv) the use of these mixtures in detergents, and (v) detergents containing 0.1-50 wt.% of these mixtures. |
