Patent number: 5834409Abstract: Mild aqueous detergent, e.g., shampoo, compositions are disclosed based on a mixture comprising anionic surfactant and amphoteric surfactant, such as betaines, present in the composition at a level of from about 0.75 to 1.25 parts by weight per part by weight of anionic surfactant. The compositions also contain one or a mixture of therapeutic agents such as climbazole or a mixture of climbazole and one or more co-therapeutics such as salicylic acid. The combination of mild surfactant system and therapeutic agent serve to prevent or treat mild skin disorders such as scalp itch and scalp irritation when applied to the scalp as a shampoo. Shampoo compositions also preferably contain one or more conditioning agents and suitable suspending agents.The invention also provides a method for treating dry skin comprising applying certain of the therapeutic agents to dry skin to promote the natural secretion of sebum.Type: GrantFiled: February 8, 1996Date of Patent: November 10, 1998Assignee: Colgate-Palmolive CompanyInventors: Pallassana Narayanier Ramachandran, Clarence Ralph Robbins, Amrit Manilal Patel

Alkylpolyglycosides with a high degree of a polymerization and a process for the preparation thereof
Patent number: 5756072Abstract: The present invention relates to a process for preparing alkylpolyglycoside compositions. Specifically the process is a direct synthesis producing compositions of highly polymerized alkylpolyglycosides in high yield. The invention further relates to alkylpolyglycoside compositions having enhanced surfactant properties. The invention also relates to mixtures of alkylpolyglycosides of preselected average alkyl chain length and controlled average degree of polymerization (DP).Type: GrantFiled: January 17, 1996Date of Patent: May 26, 1998Assignee: Cerestar Holding B.V.Inventors: Roland Herwig Friedrich Beck, Myriam Elseviers, Martine Maria Roberta Van Havere -
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
