Patent number: 5753600Abstract: A detergent composition comprising (a) 0.1 to 95% by weight of a saccharide nonionic surfactant and (b) 0.01 to 5% by weight of an antibacterial agent. The detergent compositions are outstandingly mild to the skin, exhibiting a high antibacterial effect, without influencing or weakening the cutaneous metabolic and barrier functions of the skin. The detergent compositions can effectively restrain the early occurrence of dandruff after shampooing when used as detergents for the scalp and the hair. They also exhibit high antibacterial effect when used as body detergents.Type: GrantFiled: November 14, 1994Date of Patent: May 19, 1998Assignee: Kao CorporationInventors: Jun Kamegai, Hisataka Kobayashi, Toshie Takahashi, Takashi Imamura, Sachio Naito

Patent number: 4803010Abstract: A water-soluble viscosity increasing agent consisting essentially of: (i) an ester of a 40 to 400 moles ethylene oxide adduct of polyhydric alcohol and a C.sub.8-36 branched fatty acid, (ii) an ester of polyethylene glycol having average molecular weight of 2,000 to 20,000 and a C.sub.8-36 branched fatty acid, and (iii) a 40 to 400 mole ethylene oxide adduct of an ester of a polyhydric alcohol and a C.sub.8-36 branched fatty acid. The viscosity increasing agent can increase the viscosity of solutions of various surface active agents, while maintaining their stability and solubility in the solutions. When it is formulated to a detergent suitable for washing textiles, tablewares, human skins, hairs and the like, it can provide a detergent composition with a proper viscosity as well as a good detergency.Type: GrantFiled: September 8, 1987Date of Patent: February 7, 1989Assignee: Kao CorporationInventors: Hidekazu Ogino, Hiroshi Kamitani, Jun Kamegai, Hiroki Sawada, Hajime Hirota, Tomihiro Kurosaki
