It has been found that the application of a hydrolysis process to materials, particularly materials with a high level of unsaponifiables (e.g., at least 6% w/w), produces a product with properties significantly different from those products resulting from the conventional saponification of materials with less than 6% by weight of unsaponifiables. The resulting hydrolysates from the practice of the present invention are substantive, resisting both physical and aqueous-based removal from skin and hair, exhibit a very unique surfactant property and are not foaming agents with water. Hydrolysates according to the present invention may thus be used to enhance the performance of cosmetics and pharmaceuticals. These hydrolysates can be are bioactive agents and alternative natural carrying agents for topical application of materials, particularly for application of materials to the skin or hair of subjects, and provide a substantive support for the materials carried.

Film containing compositions
US Patent Application 20110293539
Publication Date: Dec. 1, 2011
Assignee: Colgate-Palmolive Company

Disclosed is an oral care, personal care or cleansing composition with a carrier comprising a functional material and at least two polymers. One polymer has a greater solubility in water than the other polymer; one of the polymers may be water-soluble and the other polymer water-insoluble. The polymers are selected and apportioned to provide at least one of the following: a desired stability of the film in the composition, a desired rate of disintegration of the film during use of the composition and a desired rate of delivery of the functional material during use of the composition.

Color changing cleansing composition
US Patent 8067350
Publication Date: Nov. 29, 2011
Assignee: Kimberly-Clark Worldwide Inc.

A cleansing composition is disclosed that changes color during use. The cleansing composition contains a plurality of thermochromic dyes that cause a color change to occur at a threshold temperature and continue to cause a color change over a temperature range. The range of temperatures corresponds to approximately the amount of time sufficient to properly wash or scrub using the product. In general, the present disclosure is directed to an improved cleansing composition. The cleansing composition, for instance, may comprise a body wash, a facial soap, a shampoo, a baby wash, a disinfectant, a general purpose cleaner, a window cleaner, a detergent, a vehicle cleaner, pet detergent or wash or any other suitable cleaning product.
