Abstract
Novel chip compositions comprise alkylene glycol, benefit agent and thickening agent (e.g., fumed silica). Use of chips comprising excess of alkylene glycol over benefit agent and thickening agent has been found to allow significant deposition of benefit agent without compromising processing. In a second embodiment, the invention comprises bar compositions comprising mixtures of the chips of the invention and chips containing defined surfactant systems. A process for forming the chips of the invention and a method of enhancing deposition without compromising processing using the chips of the invention are also disclosed.
