Patent number: 5945108Abstract: Disclosed is water- and oil-repellent powder for cosmetic, containing a homopolymer of a polyfluoroalkyl group-containing (meth)acrylate (I) or a copolymer of the polyfluoroalkyl group-containing (meth)acrylate (I) and an alkyl (meth)acrylate (II) and/or a silicone macromonomer (III). A cosmetic containing water- and oil-repellent powder for cosmetic is superior in water- and oil-repellency and feel in use, and has almost no change of makeup.Type: GrantFiled: June 26, 1996Date of Patent: August 31, 1999Assignee: Daikin Industries Ltd.Inventors: Yasuo Sugawara, Kazuo Shimamoto, Motonobu Kubo, Masamichi Morita, Tetsuya Masutani

Patent number: 5932672Abstract: Permanently stain resistant nylon and cellulosic fibers, and a method to impart permanent stain resistance to polyamide or cellulosic fibers, by covalently binding a stain resistant composition to a linking compound that has been covalently attached to the fiber are disclosed. This invention represents a significant advance in the art of textile treatments in that the covalently linked stain resist treatment is not removed after a series of alkaline shampooins. This invention is particularly useful in the preparation of commercial grade carpets for heavy traffic areas that will not lose their stain resistance after frequent shampooing.Type: GrantFiled: March 27, 1998Date of Patent: August 3, 1999Assignee: The Secretary of State for Defence in Her Britanic Majesty's Goverment of the United Kingdom of Great Britain and Northern Ireland of Defence Evaluation & Research AgencyInventors: Colin R Willis, Stuart A Brewer

Patent number: 5905127Abstract: Mesogens are provided based on substituted unsaturated carboxylic acids such as acrylic and methacrylic acid. Substitution of a variety of hydrophobic tails onto the carboxylic acid or acid derivative via the vinyl carbon proximal to the carbonyl of the carboxylic acid results in mesogens that are capable of forming thermotropic and single-phase lyotropic mesophases over a broad range of compositions. The mesophases can be polymerized to lock in the ordered phases.Type: GrantFiled: April 8, 1997Date of Patent: May 18, 1999Assignee: The University of Southern MississippiInventors: Robert Y Lochhead, Lon J Mathias
