PURPOSE:To obtain a bleach having markedly improved stability during storage at high temperature and good bleaching power by mixing hydrogen peroxide with a surfactant and a specified organic sulfonic acid oligomer. CONSTITUTION:This bleach comprises 0.5-10wt.% hydrogen peroxide, 0.5-20wt.% surfactant and 0.005-5wt.% oligomer of the formula (wherein Y1 is H, or CO-T1; R1, Q1 and T1 are each 1-4C alkyl; and n1 is 1-16) or its alkali metal salt and has a pH of 7 or below. This composition may further contain a carboxylic acid polymer. Examples of the surfactant used include an anionic surfactant (e.g. linear or branched alkylbenzene sulfonate), a nonionic surfactant (e.g. polyoxyalkylene alkyl ether) and an amphoteric surfactant. |
