Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a surfactant composition mainly used in cosmetics.

[0002]

2.0 is shown and Example 7 discloses diammonium lauroyl glutamic acid. Also,
In JP-A-5-222395, Example 4 shows a combined use example of N-oleoyl glutamic acid monoammonium salt and palmitic acid, and Example 6 shows a combined use example of N-cocoyl glutamic acid monoammonium salt and lauric acid. There is. Further, in JP-A-54-50513, N-
The combined use of sodium, potassium or ammonium salts of acylglutamic acid with organic carboxylic acid mildly acts on the skin and provides a liquid shampoo with excellent foaming power, detergency and feel after washing, and a good texture. That is disclosed.

[0003]

However, the monoammonium salt of acylglutamic acid has low water solubility, and when it is stored at low temperature, it precipitates as crystals and does not form a body as a preparation. When stored, there is a problem that ammonia is liberated and an ammonia odor is generated. In addition, when these acyl glutamic acid ammonium salts are used as a personal cleansing agent, the foam is coarse, and it is generally called "crab foam", which is large and easily erased. It wasn't something I could get.

Therefore, the object of the present invention is to provide a surfactant composition which has good low-temperature stability and no odor when used in cosmetics, and also has a favorable foam quality and a good feeling in use.

[0005]

The present inventor has conducted extensive studies to solve the above-mentioned problems, and as a result, at least a composition of ammonium salt of N-acyl-L-glutamic acid represented by the general formula (1) was obtained. The one containing a fatty acid and / or a salt thereof having an alkyl group substantially the same as the alkyl group of the acyl group of the acylglutamic acid salt exhibits an excellent effect as compared with any of the above-mentioned conventional techniques. And found the present invention.

That is, the present invention is based on at least the general formula (1)
N-acyl-L-glutamic acid ammonium salt represented by the following, an acylglutamate composition containing a fatty acid having an alkyl group substantially the same as the alkyl group of the N-acyl group of the acylglutamate and / or a salt thereof It is about.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be specifically described below. The ammonium salt of N-acyl-L-glutamic acid in the present invention can be obtained by a commonly known method. The number of moles of ammonium ions contained in the composition of the present invention is preferably 1.2 moles or more and 1.8 moles or less, more preferably 1 mole of N-acyl-L-glutamic acid residue. Is 1.4 mol or more.
It is less than 7 mol. If it is less than 1.2 mol, the solubility of the acylglutamic acid ammonium salt is remarkably inferior particularly at low temperatures, and precipitation of the acylglutamic acid ammonium salt is likely to occur. When the solubility and odorlessness at low temperatures are more strictly required, the ratio may be 1.4 mol or more and less than 1.7 mol.

Here, the N-acyl-L-glutamic acid residue is a part of the molecular structure of the compound represented by the general formula (1) and is represented by the general formula (2).

[0010]

[Chemical 3]

From the viewpoint of improving the foam quality of the resulting composition, the fatty acid and / or its salt, which is another essential component in the composition of the present invention, is to be added, which is N-acyl-L-glutamate ammonium. It is desirable to have the same alkyl group as that of the N-acyl group of the salt, but within the range that does not impair the effects of the present invention, this alkyl group has a linear, branched or cyclic structure, a functional group, or a different type. It is also possible to use a fatty acid having a group to which an element is added and / or a salt thereof.

Further, the content of the fatty acid is preferably 0.5% by mass or more and 10% by mass or less, based on the total amount of ammonium N-acyl-L-glutamic acid present in the composition, and It is more preferable that the content is 0.7% by mass or more and 8% by mass or less. When it is 0.5% by mass or more, the effect of improving the foam quality, which is the main object of the present invention, is particularly remarkable regardless of the types and composition ratios of the other components of the composition.
When the content is at most% by mass, the solubility of the composition components will be maintained particularly at low temperatures, and it will be easy to prevent the composition components from precipitating.

In the present invention, when a fatty acid salt is used, ammonium ions are most preferable as a paired cation from the viewpoint of improving solubility and foam quality, but lithium, potassium, and Alkali metal ions such as sodium; alkaline earth metal ions such as magnesium; organic amines such as triethanolamine, diethanolamine, monoethanolamine, trishydroxymethylaminomethane, aminomethylpropanediol, and aminomethylpropanol may be used. In the present invention, one type of fatty acid and / or salt thereof may be used, or a plurality of types may be used in combination.
