  • Mild, moisturizing cleansing compositions
    Patent number: 7259131
    Abstract: Compositions used for cleansing hair and skin based on the combination of a sulfosuccinate surfactant and an amphoteric surfactant are described that are very mild but do not compromise in-use properties and economy. A route to solve the intrinsic instability of such aqueous compositions in storage has been developed based on the use of sulfosuccinic acid or a salt of sulfosuccinic acid present in an amount of at least about 4% based on the weight of the sulfosuccinate surfactant.

  • Stable cosmetic sprayable products with a desirable narrow conical spray pattern
    Patent number: 7192574
    Abstract: An aqueous leave-on hair conditioning composition which comprises: a.) about 0.01 percent to about 10.0 percent of a quaternary ammonium compound; b.) about 0.0 percent to about 10.0 percent of a silicone oil; c.) about 0.00001 to about 0.05% of a polyoxyethylene polymer; and d.) about 0.01 to 10% of a non-ionic surfactant wherein said composition is substantially free of hair hold enhancing agents and which is substantially free of cationic cellulosic resins containing tetra-substituted nitrogen moieties, is described.

  • Mild, moisturizing sulfosuccinate cleansing compositions
    Patent number: 7041627
    Abstract: Compositions used for cleansing hair and skin based on the combination of an ethoxy sulfosuccinate surfactant and an amphoteric surfactant are described that are very mild but do not compromise in-use properties and economy. It has been found desirable to utilize a mixture of a Mid-Chain alkyl ethoxy sulfosuccinate and a Long-Chain alkyl ethoxy sulfosuccinate wherein the Long-Chain component is present in the composition at a level from about 0.1% to about 6% based on the total weight of the Mid-Chain component.
