  • 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.

  • 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.

  • Publication number: 20060263319
    Abstract: Disclosed are hair treatment compositions comprising: a) from 0.01 to 5 weight percent of cationic conditioning polymer; and b) from 0.5 to 5 weight percent of dicarboxylic acid of the formula: HOOC-A-COOH wherein A is an alkylene group of the formula: —(CH2)n— where n is an integer from 2 to 8, the alkylene group A being optionally substituted with a group of the formula —SO3H, and, wherein from 0 to 100% of the dicarboxylic acid is a water-soluble salt thereof. Methods and system for treating hair using such compositions are also disclosed.

  • 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.

  • Publication number: 20060019847
    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 such as lather and are economical. A route to solve the intrinsic instability of such aqueous compositions in storage has been developed based on the use of electrolytes. The electrolytes are present at a level sufficient to provide at least about 0.1 equivalents of cationic ions per Kg of composition and maintains a viscosity of the composition at its initial value after storage for 4 weeks at 49° C.

  • Patent number: 6897194
    Abstract: In a concentrated fabric softening composition comprising an aqueous dispersion of less than 30% by weight of quaternary ammonium fabric softening material which comprises two C12-C22 alkyl or alkenyl groups connected to the molecule via at least one ester link, such as ester quat, improved stability of the viscosity on storage is obtained by including an unsaturated C8-C24 fatty acid, wherein the weight ratio of quaternary ammonium material to unsaturated material is greater than 10:1.

  • Publication number: 20030166486
    Abstract: A fabric conditioning composition comprising a cationic fabric softening compound dispersed in water is found to have surprisingly improved viscosity stability if a stabilising system comprising at least one salt of a multivalent inorganic anion or non-sequestering multivalent organic anion is present. The invention is particularly suitable for use with quaternary ammonium material comprising a compound having two C12-18 alkyl or alkenyl groups connected to the molecule via at least one ester link. Preferably, the mixture comprises sodium chloride and sodium sulphate. Preferably, there is additionally at least one salt of a univalent anion.
