manufacture example 1

[0047] Production Example 1 (Synthesis of N-coconut oil fatty acid acyl-L-alanine sodium salt)

[0048] Add 167g water to 30.0gL-alanine, keep at pH 10.98~11.02, reaction temperature 33~37 ℃, while stirring 73.68g coconut oil fatty acid chloride and 27wt%-NaOH aqueous solution, in 1 hour drops at the same time. After aging for 1 hour, the temperature of the reaction solution was increased, and 75 wt% sulfuric acid was added to adjust the pH value to 2.0. Then the temperature was raised to 80° C., and after stirring for about 10 minutes, the mixture was left to stand for 10 minutes to separate the organic layer and the water layer. About 200 g of the aqueous layer was removed from the lower part of the vessel. Hot water was added to the remaining organic layer, and the temperature was further increased to 80° C., stirred for 10 minutes, left to stand for 10 minutes, and the separated water layer was removed to obtain an organic layer. Add 27% NaOH aqueous solution and water ...

[0049] Production Example 2 (Synthesis of N-coconut oil fatty acid acyl-DL-alanine sodium salt)

[0050] The target product (N-coconut oil fatty acid acyl-DL-alanine sodium salt) was obtained in the same manner as in Production Example 1 above except that DL-alanine was used instead of L-alanine.

[0051] Detergent compositions (Examples 1-6, Comparative Examples 1-5) having the composition shown in the following Table 1 were prepared, and the following evaluation experiments were performed.

[0088] The formula shown in the table below was used to prepare facial cleanser (Example 7) and shower gel (Example 8) in a conventional manner. All of them performed well in any of the basic properties of foaming, foam volume, foam extension and foam retention, and the feeling in use was also excellent. In addition, the quantity (numerical value in a table|surface) of each compounding component described in a table|surface is the weight percentage (%) when the whole composition is taken as 100.

Abstract

This cleanser composition essentially comprises (A) a phosphoric ester-based surfactant and (B) an N-acyl-[alpha]-alanine or a salt thereof in the formulation weight ratio(A/B) of (99:1) to (40:60), wherein the component B is preferably an N-acyl-L-alanine or a salt thereof, more preferably an N-acylalanine alkali metal salt. To obtain a cleanser composition quick in foaming startup in cleansing, excellent in foam volume, foam spreadability and foam retention, giving neither residual feeling nor unfavorable touch feeling for the skin and hair in rinsing, giving moist and refreshing feeling to the skin after dried, and giving the hair moist feeling and softness and lightness.

Description

technical field [0001] The present invention relates to a skin or hair cleansing composition containing a phosphoric acid ester surfactant and N-acyl-α-alanine or a salt thereof as essential ingredients. The detergent composition of the present invention is excellent in early foaming, foam volume, foam elongation and retention during washing, and does not give skin and hair a residual or rough feeling in terms of feeling during washing, and does not give skin and hair a feeling of roughness after drying. It is a detergent composition that can give the skin a moist and refreshing feeling, and can give the hair a soft and light feeling while giving it a moist feeling. Background technique [0002] At present, anionic surfactants represented by alkyl sulfate salts, polyoxyethylene alkyl ether sulfates, long-chain fatty acid soap bases, and phosphate surfactants, and betaine-type amphoteric surfactants are due to their foam volume, It is used as a cleansing component of a skin ...
