US 8,877,091 B2 · Non-aqueous liquid oxygen bleach composition

Abstract

This invention relates to a novel non-aqueous liquid oxygen bleach composition prepared by dispersing solid peroxygen compound in the liquid in which the content of an anhydrous non-polar organic solvent and a non-ionic and anionic surfactant is controlled. The composition is formed in a high viscous paste or a gel-type suspension and can be used as a multi-purpose composition, for example, the bleach and stain remover of clothes and the cleanser of bathroom and kitchen since they have a chemical/physical stability of no loss of available oxygen, an excellent bleaching and cleaning ability due to their alkaline pH range, no change of viscosity or no phase separation during the storage and so on.

Dependent claims

A non-aqueous liquid oxygen bleach composition comprising:

a) 59 to 85 wt % of a solid peroxygen compound,
b) 10 to 38 wt % of a non-aqueous organic solvent,
c) 0.1 to 5 wt % of an anionic surfactant,
d) 0.1 to less than 10 wt % of total non-ionic surfactant,
e) 0.1 to 85 wt % of filler, and
f) 0.01 to 5 wt % of benzoic acid as a rheological stabilizer,
wherein the composition in which the solid peroxygen compound is dispersed in a liquid ingredient is a suspension composition having 500 to 5,000,000 cps (25° C.) of viscosity;
the composition has a chemical stability of more than 90%, wherein the loss of available oxygen from the composition comprising a)-f) is less than 10%;
and wherein the weight ratio of the anionic and non-ionic surfactant is 3:1 to 1:3.
