  • Patent number: 5833719
    Abstract: A process for bleaching and scouring unfinished textile materials by adding to an aqueous alkaline peroxide bath an effective amount of a surfactant composition containing(a) from about 94.0 to about 6.0% by weight of an alkyl polyglycoside having the general formula IRO(Z).sub.a (I)wherein R is a monovalent organic radical having from about 8 to about 16 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; and a is a number having a value from about 1 to about 6,(b) from about 6 to about 94% by weight of a blend of alkoxylated branched C.sub.8 -C.sub.15 alcohols, and(c) the remainder water, all weights being based on the weight of the composition;and then contacting the textile materials with the bath.

  • Patent number: 5542950
    Abstract: A surfactant composition for use in scouring and bleaching textile materials containing:(a) from about 94.0 to about 6.0% by weight of an alkyl polyglycoside having the general formula IRO (Z).sub.a (I)wherein R is a monovalent organic radical having from about 8 to about 16 carbon atoms; Z is a saccharide residue having 5 to 6 carbon atoms; and a is a number having a value from about 1 to about 6,(b) from about 6.0 to about 94.0% by weight of a synthetic alkoxylated C.sub.11 -C.sub.15 linear alcohol, or(c) from about 6.0 to about 94.0% by weight of a chlorine-capped ethoxylated isodecyl alcohol, and(d) the remainder water, all weights being based on the weight of the composition.
