Description

Delivery particles with multiple care products

field of invention

This patent application relates to delivery particles comprising benefit agents and products comprising such delivery particles, and methods for making and using such delivery particles and products comprising such delivery particles.

Background of the invention

Products, such as consumer products, may contain one or more benefit agents that can provide a desired benefit to such products and/or loci that come into contact with such products, such as stain removal and/or bleaching. Unfortunately, in certain products, such as fluid products, benefit agents, such as pre-formed peracids, can be degraded or degrade components of such products before such products are used, when the product has a pH greater than about 6 This is especially true when Therefore, a protection system that protects the components of a product from benefit agents is desirable. Efforts have been made in this area but have generally failed to provide the required level of protection or release the beneficial agent when it is required. Thus, there remains a need for encapsulating benefit agents that are effective during product use, but which do not damage such products during product storage. Applicants disclose delivery particles comprising a benefit agent, such as a preformed peracid, wherein the benefit agent is in the form of a core embedded in a matrix binder. Mixing the benefit agent core and matrix binder will form a matrix enclosed by a shell. Without wishing to be bound by theory, Applicants believe that the shell acts as a barrier to the particle's environment and that the matrix binder acts as a pool of material that absorbs any energy passing through the shell from the particle's environment. Material. The shell and matrix binder materials are chosen such that the particles are stable during storage in a product such as a consumer product, yet during use the particles release the benefit agent. Surprisingly, the method of making such particles does not unduly degrade the benefit agent, and when such particles are used in products they are stable. When such products are used for their intended purpose, they also release a suitable amount of benefit agent.

Summary of the invention

This patent application relates to particles comprising a benefit agent encapsulated by a first layer which in turn is encapsulated by a second material, products comprising such particles, and methods for preparing and Methods of using such particles and products comprising such particles.
