The invention provides a method of reducing surfactant damage in compositions comprising at least one surfactant and at least one benefit agent. The reduction in damage is measurable by decrease in number of protein binding sites in presence versus absence of benefit agent, or when benefit agent has solubility outside a defined range. The invention further relates to compositions comprising said surfactants and benefit agent(s) having reduced surfactant damage.

Method of reducing surfactant damage using compositions comprising benefit agents of defined high polarity

The invention provides a method selecting benefit agent(s) suitable for reducing surfactant damage in compositions comprising at least one surfactant and at least one benefit agent. The reduction in damage is measurable by decrease in number of protein binding sites in presence versus absence of benefit agent, or when benefit agent has solubility outside a defined range.

Method of selecting benefit agents/oils suitable for reducing surfactant damage

A convenient to use test method for comparing the relative affinity of surfactants for the skin employs a solid or semisolid matrix for associating a dye or pigment with the skin. The dye or pigment has an affinity to either the skin or a surfactant adsorbed on the skin during personal cleansing. The matrix may include a reagent soluble polymer film or temporary tattoo.
