Patent number: 6046292Abstract: 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: February 3, 1999Date of Patent: April 4, 2000Assignee: The Univeristy of Southern MississippiInventors: Robert Y Lochhead, Lon J Mathias
-
Patent number: 6007769Abstract: The present invention relates to single-phase soap gels and viscous soap compositions which are produced by alkanolamine neutralization of a fatty acid above the Krafft point. These compositions are robust, biodegradable, and are insensitive to temperature changes. The compositions also exhibit excellent cleaning properties and may be used as laundry cleaning agents, oven cleaners, hard surface cleaners, and disinfectants and air fragrancing compositions.Type: GrantFiled: May 13, 1997Date of Patent: December 28, 1999Assignee: S. C. Johnson & Son, Inc.Inventors: E. Theodore Lance-Gomez, Mark M. Gipp, Robert Y. Lochhead, Charles E. Seaman, Jr.

Patent number: 5004598Abstract: This invention relates to stable oil-in-water emulsions and to products based on such emulsions which contain a modified polymer which is a copolymer of a preponderant amount of an acrylic acid and a smaller amount of a long chain acrylate monomer which modified polymer renders the emulsions stable for over a year at room temperature and which imparts to the emulsions the quick breaking property whereby the emulsions break on coming in contact with an electrolyte or skin, instantaneously coalescing and releasing oil from the emulsions.Type: GrantFiled: May 31, 1989Date of Patent: April 2, 1991Assignee: The B.
