Liquid compositions comprising bleaching and/or hygiene agents of low aqueous solubility.

摘要

The invention provides stable, aqueous, hygiene compositions comprising aqueous-insoluble or sparingly soluble organic peroxy acids can be prepared by the use of a water-immiscible solvent for the organic peroxy acid in the form of an emulsion in water. In the context of the present invention aqueous-insoluble or sparingly soluble organic peroxy acids are those peroxy acids having a solubility in water at 10 DEG C of less than 100ppm. Compositions according to the invention comprise: at least 100 ppm of a water insoluble or sparingly soluble hygiene agent (a), and, at least 0.1% of a water-immiscible solvent for (a), said solvent comprising the dispersed phase of a solvent/water emulsion. Typically the bleaching agent (a) is an organic peroxy acid. Typically, the peroxy acid is an imido peroxy-carboxylic acid, most preferably e-N-N-phthaloyl-amino-peroxycaproic acid (PAP).
