  • Publication number: 20110302724
    Abstract: A method for bleach-whitening of synthetic textile material is provided comprising contacting said textile material with (a) an enzymatic textile bleaching composition comprising (i) a perhydrolase enzyme, (ii) an ester substrate for said perhydrolase enzyme, (iii) a hydrogen peroxide source, (iv) a surfactant and/or an emulsifier, (v) a peroxide stabilizer, (vi) a sequestering agent, (vii) a buffer which maintains a pH of about 6 to about 8, and (b) at least one fluorescent whitening agent, and, optionally, (c) at least one acid or disperse shading dye for shaded variations of white, for a length of time and under conditions suitable to permit measurable whitening of the textile material, thereby producing a bleached-whitened textile material.

  • Publication number: 20070186354
    Abstract: Compositions which, as well as water, contain certain sulfonate salts or polyhydric alcohols together with ethoxylated/propoxylated alcohols and ethoxylated alcohols and also poly(meth)acrylic acid, polymaleic acid or partially hydrolyzed polymaleic anhydride are useful for pretreating textile sheet materials. Further ingredients also render them useful for hydrogen peroxide bleaching. The compositions, which provide the textiles with good primary wettability and good rewettability, are low-foaming. Batchwise pretreatment processes, for example in jet machines, therefore represent no problem.

  • Patent number: 6982243
    Abstract: Water-soluble granules of salen-type manganese complexes that are suitable as catalysts in reactions with peroxy compounds are described. The granules are used especially in washing agents. They are distinguished by retarded dissolution of and improved action of the manganese complexes.
