DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/JP95/00988 filed 23 May 1995.
TECHNICAL FIELD
The present invention relates to a novel amine compound, which is useful as a base for hair and skin cosmetic compositions, a detergent, an emulsifying agent, a conditioning agent, or the like, an intermediate useful for the preparation thereof, and detergent compositions containing such an amine compound.
BACKGROUND ART
Surfactants such as alkylsulfates, polyoxyethylene alkylsulfates and alkylbenzenesulfonates have heretofore been used as detergents. However, many of these surfactants involve a problem that they irritate the skin to a somewhat strong extent upon their use. For this reason, surfactants low in skin irritation, such as alkylphosphates and salts of acylated amino acids, have come to be used as bases or emulsifying agents for hair and skin cosmetic compositions, or detergents for the skin and the like. With the diversification of consumer demand and inclination to high-quality goods, there have recently been demand for development of compounds which have good foamability and such effects that a pleasant feeling can be given to the user's skin and the like, in addition to low irritativeness to the skin and the like. However, no compound fully satisfying these requirements has been yet developed.
Accordingly, it is an object of the present invention to provide a compound which can solve the above problems, has low irritativeness to the skin and the like and excellent foamability, can give a pleasant feeling to the user's skin and the like, and is useful as a base for hair and skin cosmetic compositions, a detergent, an emulsifying agent, a conditioning agent, and the like.
In view of the foregoing circumstances, the present inventors have carried out an extensive investigation. As a result, it has been found that novel amine compounds represented by the general formula (1), which will be described subsequently, can serve as anionic surfactants, have low irritativeness to the skin and the like, give a pleasant feeling to the user's skin and the like, and have excellent foamability, thus leading to completion of the present invention.
Incidentally, as compounds having a structure close to that of the compounds according to the present invention, there have been known compounds having a 2-hydroxypropanediamine structure (U.S. Pat. No. 3,654,158, DE Patent No. 3,607,884, U.S. Pat. No. 4,982,000 and Japanese Patent Application Laid-Open Nos. 233264/1989 and 223515/1990, etc.). Since these compounds have a diamine structure and besides have no anionic functional groups such as a carboxyl group, a sulfonic group and a sulfuric acid residue, however, they are greatly different from the compounds of the present invention, which are anionic surfactants having a triamine structure, in both structure and function.
DISCLOSURE OF THE INVENTION
According to the present invention, there is thus provided an amine compound represented by the following general formula (1): ##STR2## wherein R.sup.1 and R.sup.2 are the same or different from each other and represent individually a linear or branched alkyl or alkenyl group which may be substituted by a hydroxyl group and has 1-24 carbon atoms, X.sup.1 represents an alkylene or alkenylene group which may be substituted by at least one hydroxyl, sulfonic or carboxyl group and has 1-6 carbon atoms, Y.sup.1 represents a carboxyl or sulfonic group, or a sulfuric acid residue, Y.sup.2 represents a hydroxyl group, a sulfuric acid residue or a group --OCO--X.sup.1 --COOH, Z represents a sulfoalkyl group or a group obtained by removing an amino group from an amino acid or a salt thereof, and n represents a number of 0 or 1, or a salt or quaternized product thereof.
According to the present invention, there is also provided an aminoalcohol compound which is an intermediate useful for the preparation of the amine compound (1) and represented by the following general formula (2): ##STR3## wherein R.sup.1 and R.sup.2 are the same or different from each other and represent individually a linear
