Title:
BLEACH ACTIVATORS WITH IMPROVED SOLUBILITY
Document Type and Number:
WIPO Patent Application WO2001046372
Kind Code:
A3
Abstract:
Bleach activator particle for use in detergent compositions, comprising a bleach activator having the general formula (I): wherein R is an alkyl group containing from about 5 to about 18 carbon atoms wherein the longest linear alkyl chain extending from and including the carbonyl carbon contains from about 6 to about 10 carbon atoms and L is leaving group, the conjugate acid of which has a pKa in the range of from about 4 to about 13, preferably from about 6 to about 11, most preferably from about 8 to about 11; and a binder material comprising from about 0.1 % to about 15 %, by weight of the particle, of an inorganic salt capable of absorbing water of hydration; or a binder material comprising 0.1 %-15 % by weight of a saturated fatty acid having less than 16 carbon atoms, and wherein the particle contains no fatty acid having more than 16 carbon atoms.
