Claims12
A process of treating a fabric which comprises the step of contacting said fabric with a bleaching composition, in its neat form, wherein said bleaching composition comprises a peroxygen bleach and a high molecular weight polymer selected from the group consisting of a homopolymer of acrylic acid having a molecular weight of from 1×105 to 1×108, copolymers of acrylic acid having a molecular weights of from 1×105 to 1×108 and mixtures thereof.
A method of reducing the evaporation of a solvent contained in a peroxygen bleach-containing composition, said method comprising combining a high molecular weight polymer selected from the group consisting of a homopolymer of acrylic acid having a molecular weight of from 1×105 to 1×108, copolymers of acrylic acid having a molecular weights of from 1×105 to 1×108 and mixtures thereof with said peroxygen bleach-containing composition.
