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.
