US 2012/0071391 A1 · BENEFIT AGENT CONTAINING DELIVERY PARTICLE

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, there by 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.

Claims18

Dependent claims

A composition comprising:

benefit agent delivery particles comprising a core material and a shell, said shell at least partially surrounding said core material;
wherein:
i. at least 75% of said benefit agent delivery particles having a fracture strength of from about 0.2 MPa to about 10 MPa;
and
ii. said particles having a benefit agent leakage of from 0% to about 30% wherein said benefit agent delivery particles have wall materials which comprises a resin selected from the group consisting of a reaction product of an aldehyde with an amine.
