Abstract:
1. A method of selecting benefit agent or agents suitable to reduce surfactant damage in compositions comprising at least one anionic surfactant and at least one benefit agent, wherein said reduction is measurable by decrease in number of protein binding sites binded by surfactant when benefit agent is present compared to when benefit agent is absent, or compared to when benefit agent used has solubility outside defined range, wherein said method comprises: (1) determining the Hansen solubility parameter of said benefit agent; and (2) selecting or using said benefit agent or agents having a Hansen benefit agent solubility of 16.5 to 37 wherein, when said selected benefit agent or agents having said Hansen solubility is used in said composition compsing said at least one anionic surfactant and said benefit agent of agents, said reduced surfactant damage is seen.
