DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a 2-hydroxypropanediamine 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.
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 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, 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, has low 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 from irritation to the skin and the like, thus leading to completion of the present invention.
According to the present invention, there is thus provided a 2-hydroxypropanediamine derivative represented by the following general formula (1): ##STR3## wherein R.sup.1 and R.sup.2 are identical with or different from each other and mean individually a linear or branched alkyl or alkenyl group having 6-36 carbon atoms, X denotes 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 is a sulfonic group, a sulfuric acid residue or a carboxyl group, Y.sup.2 means a hydroxyl group, a sulfuric acid residue or ##STR4## and n stands for 0 or 1, or a salt or quaternized product thereof.
According to the present invention, there is also provided a detergent composition comprising this 2-hydroxypropanediamine derivative (1), or a salt or quaternized product thereof.

BEST MODE FOR CARRYING OUT THE INVENTION
As compounds having a 2-hydroxypropanediamine structure, there have been known those disclosed in 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, and the like. However, these compounds have no anionic functional groups such as a carboxyl group, a sulfonic group and a sulfuric acid residue, and are hence greatly different from the compounds according to the present invention in both structure and function.
