Patent number: 6335468Abstract: There is provided a process for producing an N-acyl amino acid amide, comprising a condensation reaction of an N-acyl amino acid with an amine and/or an ammonia, preferably a primary amine, a secondary amine and/or an ammonia under dehydration in the presence of a boron compound as the catalyst under coexistence of an alcohol as the auxiliary solvent, at a high yield for a short time. A medium for hylotropic dehydration such as hydrocarbon compounds may be used in the reaction.Type: GrantFiled: October 2, 2000Date of Patent: January 1, 2002Assignee: Ajinomoto Co., Inc.Inventors: Toshihiko Hatajima, Tatsuru Tabohashi

Patent number: 5968492Abstract: A composition suitable for hair care which has excellent hair conditioning effects and provides a pleasant sensory feeling during use. The composition contains basic amino acids and high alcohols, and is preferably free of non-polymeric alkyl quaternary ammonium salts, which are irritating and poorly biodegradable. The composition may also contain cationic polymers to enhance the conditioning effects. Anionic surface active agents, ampholytic surface active agents, or both, may also be incorporated into the hair care composition in order to impart hair cleansing properties.Type: GrantFiled: September 2, 1997Date of Patent: October 19, 1999Assignee: Ajinomoto Co., Inc.Inventors: Yasunobu Noguchi, Tatsuru Tabohashi
