DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to tris(3-aminopropyl)amine derivatives, salts and quaternized products thereof, and intermediates therefor, which are useful as bases for hair or skin cosmetic compositions, detergents, emulsifiers, conditioning agents or the like.
BACKGROUND ART
As detergents, surfactants such as alkyl sulfates, polyoxyethylene alkylsulfates and alkylbenzene sulfonates have conventionally been used. Many of these surfactants are however accompanied with the drawback that their skin irritation is slightly strong upon practical use. In consideration of such a problem, surfactants having weak skin irritation, for example, alkylphosphates and acylated amino acid salts have come to be used as a base or emulsifier for a hair or skin cosmetic composition, a detergent for skin, or the like. Furthermore, reflecting the diversified demand of users and their inclination to higher-grade products, there has recently been a request for the surfactants which have, in addition to less skin irritation, advantages such as good foaming power, capability of imparting good touch feeling to the skin, and the like. However, there has so far been no surfactants which can satisfy such requests.
Accordingly, an object of the present invention is to provide a compound which has less skin irritation, is excellent in foaming power, can impart the skin or the like with favourable touch feeling and is therefore useful as a base for hair or skin cosmetic compositions, detergents, emulsifiers or conditioning agents.
DISCLOSURE OF THE INVENTION
With forgoing in view, the present inventors have conducted an extensive investigation. As a result, it has been found that a novel compound represented by the formula (1), which will be described below, has low skin irritation, imparts the skin or the like with favourable touch feeling, and has excellent foaming power. It has also been found that the incorporation of the above compound makes it possible to provide a detergent having excellent detergency and foaming power and is free from skin irritation, leading to the completion of the invention.
The present invention therefore provides a tris(3-aminopropyl)amine derivative represented by the following formula (1): ##STR2## wherein R represents a linear or branched C.sub.1-24 alkyl or alkenyl group which may be substituted by a hydroxyl group, A represents a linear or branched C.sub.1-6 alkylene or alkenylene group which may be substituted by a hydroxyl group, a carboxyl group or a sulfonic acid group, Y.sup.1 represents a carboxyl group, a sulfonic acid group or a sulfuric acid residue; Y.sup.2 represents a hydroxyl group, a sulfuric acid residue or a group --OCO--A--COOH; and n stands for 0 or 1; a salt and quaternized product of the derivative; and an intermediate for the derivative.
The present invention also provides a detergent composition comprising the above tris(3-aminopropyl)amine derivative (1), or a salt or quaternized product of the derivative.
BEST MODES FOR CARRYING OUT THE INVENTION
As compounds each having a structure close to that of the compound of the present invention, compounds having a 2-hydroxypropanediamine structure (described in U.S. Pat. No. 3,654,158, German Patent No. 3607884, U.S. Pat. No. 4,982,000, Japanese Patent Laid-Open No. Hei 1-233264, Japanese Patent Laid-Open No. Hei 2-223515 and the like) are known. However, these compounds have a diamine structure and do not contain an anionic functional group such as carboxyl group, sulfonic acid group or sulfuric acid residue so that they are largely different from the compound of the present invention in its structure and function.
R in the above formula (1) represents a linear or branched C.sub.1-24 alkyl or alkenyl group which may be substituted by a hydroxyl group and as the specific examples of it, the following groups can be given.
Examples of the linear alkyl group include methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, oct
