[0002]

2. Description of the Related Art As a surfactant composition for cosmetics, N
-Acyl-L-glutamic acid monotriethanolamine salts have been used, but for various reasons, alternatives to triethanolamine have been sought. Further, a method using a metal salt such as sodium or potassium for this purpose is also known, but the feeling of use is too refreshing to be sufficient as a substitute for a triethanolamine salt.

[0003]

An object of the present invention is to provide a surfactant which does not become too refreshing when used, has a moderate moist feeling, and has a feeling close to that of an N-acylamino acid monotriethanolamine salt. Make it an issue.

Means for Solving the Problems The present inventors have made intensive studies to solve the above problems, and as a result, have found that N-acylamino acids, N, N-bis (2-hydroxypropyl) amine, N, N-tris (2-hydroxypropyl)

That is, the present invention provides an N-acylamino acid, N, N-bis (2-hydroxypropyl) amine,
N, N, N-tris (2-hydroxypropyl) amine, N- (2-hydroxyethyl) -N- (2-hydroxypropyl) amine, N- (2-hydroxyethyl)

N ', N'-tetrakis (2-hydroxypropyl) ethylenediamine, N, N-bis (1-hydroxypropyl) amine, and 2,2-bis (hydroxymethyl)
The present invention relates to a surfactant composition characterized by being a salt with at least one selected from the group consisting of -2,2,2-nitrilotriethanol.

N-acylamino acids, one essential component of the present invention, are now widely known and are available in natural and synthetic forms.
It has a structure in which an acyl group having 8 to 22 carbon atoms is bonded by an amide bond to an amino group of an amino acid which is a substance containing at least one amino group and one carboxyl group in the same molecule. More specifically, N-acylglutamic acid, N-acylaspartic acid, N-acyl-β-alanine, N-acyl-N-methyl-β-alanine,
Acylmethyltaurine, N-acylsarcosine and the like, and methods for producing these substances are known. Above all,
N-acyl-L-glutamic acid has a good feeling in use and is preferably used.

Conventionally, when these substances are used as a surfactant, inorganic ions such as sodium, potassium, lithium, magnesium, and ammonia, or monoethanolamine, diethanolamine, triethanolamine, and 2-amino- Usually, salts with organic ions such as 2-methylpropanol, 2-amino-2-methylpropanediol, 2-amino-2-hydroxymethylpropanediol, arginine, lysine and histidine were used. Above all, triethanolamine salts are not only excellent in workability but suitable as industrial raw materials, and have been favored as surfactants for cosmetics because of their moist feeling.

However, in recent years, there have been demands for alternatives to triethanolamine due to various circumstances.
For this reason, the use of the various cations listed above as an alternative to triethanolamine has been studied. No user-satisfying alternative to triethanolamine was found because of its significant difference from the ethanolamine salt.

Therefore, the present inventors have conducted intensive studies and as a result,
N, N-bis (2-hydroxypropyl) amine, N,
N, N-tris (2-hydroxypropyl) amine, N
-(2-hydroxyethyl) -N- (2-hydroxypropyl) amine, N- (2-hydroxyethyl) -N-
(2-hydroxybutyl) amine, N- (2-hydroxybutyl) -N- (3-hydroxy-2-methylpropyl) amine, N- (2-hydroxypropyl) -N-

N- (2-hydroxybutyl) amine, N, N, N ',
N'-tetrakis (2-hydroxypropyl) ethylenediamine, N, N-bis (1-hydroxypropyl) amine, and 2,2-bis (hydroxymethyl) -2,
By using at least one amine selected from the group consisting of 2,2-nitrilotriethanol as a counter ion of N-acylamino acid, a composition having a feeling similar to that of N-acylamino acid triethanolamine salt can be obtained. I found that I can do it.

When neutralizing N-acylamino acids using these substances, the equivalent ratio of carboxyl groups contained in N-acylamino acids to amino groups contained in amines is COO / N = 0.3. It is preferably from 2.0 to 2.0. If the ratio is less than 0.3, not only sufficient performance as a surfactant cannot be obtained, but also a stable preparation cannot be obtained due to low solubility. On the other hand, if the ratio exceeds 2.0, not only the performance corresponding to the added amount cannot be expected but also the function as a surfactant such as foaming and surface tension is hindered.

The surfactant composition of the present invention is mainly used for cosmetics, but may be used for other household surfactants.
Useful as research surfactants and industrial surfactants, basic cosmetics such as shampoos, rinses, body soaps, hand soaps, cleansing foams, cleaning soaps such as solid soaps, transparent soaps, cold creams and burnishing creams , Hair cosmetics such as hair cream and hair foam, bathing agents such as bubble bath, other emulsifiers, emulsion polymerization agents, chemicals for oil fields, surface cleaners, laundry cleaners, dishwashing cleaners, paper processing and plasterboard It can be used for molding. The combination of N-acylamino acid and amine used is N-acylglutamic acid and N, N, N ′, N′-tetrakis (2-hydroxypropyl) ethylenediamine in combination with N-acylglutamic acid monotriethanolamine salt. Is most preferable because of the similarity of the feeling of
