Abstract
Abstract A liquid detersive bleaching composition which comprises 3 to 10 wt.% of sodium hypochlorite (in terms of the amount of available chlorine), 0.5 to 3 wt.% of caustic alkali, 0.3 to 7 wt.% of polyoxyethylene alkylphenyl ether sulfate (a) having the formula (I) and 0.1 to 5 wt.% of polyoxyethylene alkylphenyl ether sulfate sulfonate (b) having the formula (II), wherein the molar ratio of (a) to (b) is in the range of from 20/80 to 85/15 and the total amount of (a) and (b) is in the range of from more than 0.5 wt.% to less than 10 wt.%.

Claim 1
Independent Claim
162 words
A liquid detersive bleaching composition, consisting essentially of: a. from 0.3 to 7 weight percent of a substance having the formula ##STR5## wherein R is alkyl having 5 to 15 carbon atoms, m is an integer from 3 to 15, and M is Na or K; b. from 0.1 to 5 weight percent of a substance having the formula ##STR6## wherein R' is alkyl having 5 to 15 carbon atoms, n is an integer from 3 to 15, and M is Na or K, the sum of component a plus component b being from more than 0.5 weight percent to less than 10 weight percent, and the molar ratio of a/b being in the range of from 20/80 to 85/15; c. from 3 to 10 weight percent, calculated as available chlorine, of sodium hypochlorite; d. from 0.5 to 3 weight percent of caustic alkali; e. up to less than 10 weight percent of sodium benzenesulfonate; and f. the balance is essentially water.
Claim 2
Dependent Claim
