PURPOSE:To obtain a bleach compsn. having a high bleaching effect and being not causative of discoloration or fading of colored or figured cloth by using hydrogen peroxide or a peroxide capable of forming hydrogen peroxide in an aq. soln. in combination with a polymer having specific monomer units and a pullulanase. CONSTITUTION:A bleach compsn. comprises 50-99.4wt.% hydrogen peroxide or 50-99.4wt.% peroxide capable of forming hydrogen peroxide in an aq. soln., 0.05-10wt.% polymer, compolymer or water-soluble salt thereof having monomer units of the formula (X, Y and Z are each H, CH3, COOM, CH2COOM, or OH; M is H, an alkali metal, or a mixture thereof; and n>=2), and an alkaline pullulanase or an alkali-resistant pullulanase. The pullulanase to be used is pref. one separated and collected from a culture of a microogranism belonging to the genus Bacillus. |
