Abstract: The present disclosure relates to benefit agent delivery particles containing at least one benefit agent and at least one cellulosic polymer. The disclosure further relates to compositions containing benefit agent delivery particles and processes for making and using such compositions. The disclosure further relates to methods of imparting a benefit delivery capability to a cleaning composition.

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.
