Abstract
The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, thereby allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.
Claims39
A composition comprising:
- a) benefit agent delivery particles,
- said benefit agent delivery particles being self-assembling graft co-polymer capsules,
- said benefit agent delivery particles comprising at least one self assembling graft co-polymer and a benefit agent, said benefit agent being encapsulated in said self assembling graft co-polymer, and/or being partially embedded in said self assembling graft co-polymer,
- wherein said self assembling graft co-polymer comprises a co-polymer of polyalkylene glycol and vinyl acetate, where said co-polymer comprises a polyalkylene glycol backbone and vinyl acetate moieties that are covalently attached to said polyalkylene glycol backbone;
- b) an adjunct material;
- and
- c) a free water content of about 96% or less.
Benefit agent delivery particles comprising a benefit agent and at least one self-assembling graft co-polymer, wherein said benefit agent delivery particles have a Dissolution Index of 1, a self-assembly index of from 1 to about 100, and/or a SAXS index of from 1 to about 100,
- said benefit agent delivery particles being self-assembling graft co-polymer capsules,
- wherein said self-assembling graft co-polymer comprises a co-polymer of polyalkylene glycol and vinyl acetate, where said co-polymer comprises a polyalkylene glycol backbone and vinyl acetate moieties that are covalently attached to said polyalkylene glycol backbone.
