Patent number: 6432393Abstract: The invention relates to aqueous hair care compositions including conditioners, shampoos, and mousses. The invention also relates to methods of treating hair, and more particularly to treating hair with aqueous hair care compositions which contain one or more elastomeric resinous materials. These materials when tested at the same concentration that could be incorporated into a product exhibit a G′ modulus between 1×102 and 1×105 dynes/cm2. Furthermore these resins when mixed with a hydrophilic or hydrophobic diluent at a ratio of 1:95 to 95:1% and this mixture then incorporated into an aqueous emulsion in the range of 0.1 to 10% have been demonstrated to deliver a consumer perceptible increase in hair body without sacrificing conditioning attributes.Type: GrantFiled: June 5, 1998Date of Patent: August 13, 2002Assignee: Helene Curtis, Inc.Inventors: Wolfgang Robert Bergmann, John Edward Wydila, Ben Janchitraponvej, Paul Howard Neill, Chaitanya Umedbhai Patel, Christophe Michel Finel, Walter Thomas Gibson, Roger Michael Lane
