Abstract (en)
[origin: WO2010100028A2] 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.
