Abstract
Compositions that contain a co-particle, a bleach catalyst, and optionally, a detergent adjunct material are disclosed. The disclosed co-particles contain a binder, a hydrogen peroxide source, such as sodium percarbonate or the like, and a bleach activator such as TAED. Methods of making and using these compositions are also disclosed.
Claims25
A composition comprising
- a. a layered particle comprising a core and a layer, said core comprising a hydrogen peroxide source and said layer comprising a binder and a bleach activator, wherein said hydrogen peroxide source and said bleach activator are present in said layered particle at a weight ratio of from about 5:1 to about 1.1:1;
- b. an organic catalyst selected from the group consisting of iminium cations and polyions;
- iminium zwitterions;
- modified amines;
- modified amine oxides;
- N-sulphonyl imines;
- N-phosphonyl imines;
- N-acyl imines;
- thiadiazole dioxides;
- perfluoroimines;
- cyclic sugar ketones;
- and combinations thereof;
- and
A composition according to claim 23 wherein said composition comprises, based on total composition weight, from about 0.01% to about 100% of said layered particle.
