Patent number: 7056496Abstract: The present invention includes a process of preparing an advanced cosmetic product by combining a high internal phase ratio (HIPR) emollient-in-water emulsion with a partial cosmetic formulation that typically contains water, a coloring agent, a fragrance, a rheology modifier, or a pH adjuster, or a combination thereof. The present invention also includes compositions directed to two particular subclasses of HIPR emollient-in-water emulsions, namely an HIPR silicone elastomer-in-water emulsion and an HIPR sunscreen-in-water emulsion and water-diluted dispersions thereof. The use of an HIPR emulsion of a cosmetic emollient provides a simple and flexible method of formulating the cosmetic product, due in part to the long shelf-stability of the HIPR emulsion (greater than 1 year), and the low quantity of water in the emulsion (typically less than 20% by volume based on the volume of emollient and water).Type: GrantFiled: February 21, 2003Date of Patent: June 6, 2006Assignee: Dow Global Technologies Inc.Inventors: James E. Pate, Dale C. Schmidt, David L. Malotky, Anthony S. Drager, Letha M. Gatz, Christian Piechocki

Patent number: 6512024Abstract: Stable aqueous dispersions or emulsions can be prepared by merging into a mechanical disperser a stream of a molten or liquid disperse phase with a stream of a molten or liquid continuous phase to form a dispersion or emulsion. The molten or liquid disperse phase stream contains a polymer that is preferably a solid at room temperature, but molten at some advanced temperature. The polymer is formed in a molten state or formed and melted by a continuous reaction process such as an extrusion process, including melt extrusion or compound extrusion. It has been discovered that low polydisperse submicron sized dispersion can be prepared by the method of the present invention.Type: GrantFiled: May 19, 2000Date of Patent: January 28, 2003Assignee: Dow Global Technologies Inc.Inventors: Richard A.

Patent number: 6156806Abstract: The present invention is a composition comprising either: a) a high internal phase ratio emulsion having water as a continuous phase and a thermoplastic hydroxy-functional polyether as a disperse phase; or b) a stable aqueous dispersion of the thermoplastic hydroxy-functional polyether. The composition of the present invention addresses a need in the art by providing a thermoplastic coating that exhibits an excellent barrier to oxygen and carbon dioxide, but which barrier properties are not adversely affected by contact with water. The composition is particularly useful in the paper packaging industry where biodegradability and resistance to spoilage of food is desirable.Type: GrantFiled: August 26, 1998Date of Patent: December 5, 2000Assignee: The Dow Chemical CompanyInventors: Christian Piechocki, James E.
