Claim 1
Independent Claim
163 words
An aqueous alkaline bleaching composition for textile fabrics or yarns, said bleaching composition comprising per liter from 10 to 100 ml of 35% by weight hydrogen peroxide, from 5 to 20 g of bases, from 5 to 50 of stabilizers, from 0.1 to 1.0 g of magnesium salts, from 0.5 to 10 g of sequestering agents, and from 0.3 to 30 g, based on active substance, of alkali, ammonium, or amine salts of carboxylic acid polyoxyalkyl ester sulfonic acids prepared by reaction of monounsaturated monocarboxylic acid polyoxyalkyl esters corresponding to the following general formula: ##STR4## in which R is a C 1-22 alkyl radical or a C 3-22 alkenyl radical, m is a number of 10 to 21, n is independently selected for each OC n H 2n group from the number 2 and the number 3, and x is a number from 1 to 20, with sulfur trioxide and subsequent reaction of the sulfonated monocarboxylic acid polyoxyalkyl esters obtained with aqueous alkalis.
