1. A composition comprising an adjunct ingredient and, based on total composition weight, from about 0.1% to about 50%, particles, each of said particles independently having a particle size of from about 2 microns to about 80 microns, and each particle comprising:
- a) a core that comprises, based on total particle weight, from about 6% to about 99.9% of a benefit agent and from about 0.1% to about 94% of a partitioning modifier comprising an oil soluble material that has a ClogP greater than about 4; and
b) a shell that encapsulates said core, said shell comprising, based on total shell weight, from about 50% to about 100% of a polyacrylate;
said composition being a consumer product;
wherein said benefit agent and said partitioning modifier are different materials;
wherein said partitioning modifier is selected from the group consisting of isopropryl myristate; and
wherein said polyacrylate comprises a polyacrylate random copolymer, said polyacrylate random copolymer comprising, based on total polyacrylate weight;
a) from about 0.2% to about 2.0% amine content;
b) from about 0.6% to about 6.0% carboxylic acid;
or c) from about 0.1% to about 1.0% amine content and from about 0.3% to about 3.0% carboxylic acid.

Abstract
The present application relates to encapsulated benefit agents, compositions comprising such encapsulated benefit agents and processes for making and using compositions comprising such encapsulated benefit agents. Such encapsulated benefit agents eliminate or minimize one or more of the drawbacks of current encapsulated benefit agents and thus provide formulators with additional perfume delivery opportunities.
