DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/JP94/01923, filed Nov. 14, 1994.
TECHNICAL FIELD
The present invention relates to an amine derivative, or a salt or quaternized product thereof, 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 a derivative.
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 for hair and skin cosmetic compositions, emulsifying agents or detergents for the skin and the like. With the diversification of demand and inclination to high-quality goods of consumers, 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, is low in irritativeness to the skin and the like and excellent in 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, or the like.
DISCLOSURE OF THE INVENTION
In view of the foregoing circumstances, the present inventors have carried out an extensive investigation. As a result, it has been found that a novel compound represented by the general formula (1), which will be described subsequently, is low in irritativeness to the skin and the like, gives a pleasant feeling to the user's skin and the like, and has excellent foamability, and that the incorporation of this compound permits the provision of a detergent excellent in detergency and foaming power, and free of irritation to the skin and the like, thus leading to completion of the present invention.
According to the present invention, there are thus provided an amine derivative represented by the following general formula (1): ##STR2## wherein R.sup.2 and R.sup.3 are identical with or different from each other and mean individually a linear or branched alkyl or alkenyl group which may be substituted by a hydroxyl group and has 1-24 carbon atoms, A denotes a linear or branched alkylene or alkenylene group which may be substituted by at least one hydroxyl, carboxyl or sulfonic group and has 1-6 carbon atoms, Y.sup.1 is a carboxyl or sulfonic group, or a sulfuric acid residue, Y.sup.2 means a hydroxyl group, a sulfuric acid residue or a group --OCO--A--COOH, n stands for a number of 0 or 1, and p is an integer of 1-8, or a salt or quaternized product thereof, and intermediates useful for the preparation thereof.
According to the present invention, there is also provided a detergent composition comprising this amine derivative (1), or a salt or quaternized product thereof.
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 cannot be used as detergent components. Therefore, they are greatly different from the compounds according to the present invention in both structure and function.
