Description

  The present invention relates to a composition that is highly transparent and that does not become sticky even if it is adjusted to water and applied to the skin.

  In order to adjust oil-soluble substances used in cosmetics and the like in a transparent state in water, it is necessary to use a solubilizer. Conventionally, it is known that a nonionic surfactant that can easily form micelles from a low concentration is preferable as a solubilizer. A considerable amount of surfactant is required to solubilize the oil-soluble substance. However, when an oil-soluble substance is applied on the skin, the feel of the surfactant remaining on the skin, that is, stickiness, etc. remains. Therefore, reduction of the amount of surfactant is required.

  The compound represented by the general formula (1) was produced by the method described below.

[Production Example 1]
9.1 g (0.05 mol) of L-lysine hydrochloride was mixed with 57 g of water. This liquid was stirred while adjusting the pH range to 10 to 11 with a 25% aqueous sodium hydroxide solution and maintaining the reaction temperature at 5 ° C. Under stirring, 31.1 g (0.1 mol) of N-lauroyl-L-glutamic anhydride was added over 2 hours to carry out the reaction. Thereafter, stirring was continued for another 30 minutes, and tertiary butanol was added to a concentration of 20% by mass in the liquid, 75% sulfuric acid was added dropwise to adjust the pH value of the liquid to 2, and the liquid temperature was adjusted to 65. Adjusted to ° C. After completion of the sulfuric acid addition, stirring was stopped, and the mixture was allowed to stand at 65 ° C. for 20 minutes to separate into an organic layer and an aqueous layer, and the organic layer was separated therefrom. Tertiary butanol and water were added to the separated organic layer, the temperature was raised to 65 ° C., and the mixture was stirred for 20 minutes. After the stirring was stopped, the mixture was allowed to stand to separate into an organic layer and an aqueous layer. After repeating the same water washing operation described above for the obtained organic layer, the solvent was removed from the obtained organic layer, and the resulting solution was made into an aqueous solution having a solid content of 30% by mass and pH 6.5 (25 ° C.) with sodium hydroxide. After neutralization and preparation, this was dried to obtain a compound represented by the following formula (4).

  In the reaction of N-lauroyl-L-glutamic anhydride and L-lysine hydrochloride, four types of compounds are produced as shown by the following formula (4) depending on the way of binding.

(In Formula (4), R is a hydrocarbon group having 11 carbon atoms, and M is independently H or Na.)

[Production Example 2]

  Since N-lauroyl-L-glutamic acid anhydride of Production Example 1 was changed to N-cocoyl-L-glutamic acid anhydride, in the above formula (4), R is a hydrocarbon group having 7 to 17 carbon atoms.

[Production Example 3]
In the manufacture example 1, it implemented on the same conditions as the method of the manufacture example 1 except having implemented the neutralization process with potassium hydroxide.
