  • Method of selecting benefit agents/oils suitable for reducing surfactant damage
    Patent number: 7799748
    Abstract: 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 reducing surfactant damage using compositions comprising benefit agents of defined high polarity
    Patent number: 7799747
    Abstract: 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.
