Description

The present invention relates to a skin or hair cleansing composition.

Anionic surfactants and amphoteric surfactants are used in large amounts in the skin cleansing composition in order to realize excellent cleansing power and abundant foam amount. However, if the skin is washed repeatedly with a surfactant, it may wash away the necessary moisturizing ingredients of the skin as well as excess sebum and dirt, and it is excellent in detergency, foam performance such as abundant foam amount, and rinsing property. At the same time, it is required to be mild to the skin.
There are two types of moisturizing ingredients that the skin originally has: natural moisturizing ingredients contained in the stratum corneum cells existing on the surface of the skin and intercellular lipids that fill the circumference of the stratum corneum cells. When the component of is lost, the moisturizing function of the skin tends to decrease. In general, anionic surfactants are known to facilitate elution of natural moisturizing components in stratum corneum cells. Therefore, a skin cleansing agent that prevents the elution of natural moisturizing components by anionic surfactant and is mild to the skin has been studied.
For example, Patent Document 1 describes that a detergent composition containing a polyoxyethylene alkyl ether carboxylate having a specific distribution has excellent foaming performance and good rinsing property. In Patent Document 2, a skin cleansing composition in which an alkyl ether carboxylate having a specific distribution and an acylated amino acid salt are combined has excellent foaming and foaming quality, and an elastic foam can be obtained, which is applied when rinsing. It is stated that it does not work. Non-Patent Document 1 reports that a mixed component of a polyoxyethylene alkyl ether carboxylate and an anionic surfactant of a fatty acid salt has both gentleness to the skin and detergency.
On the other hand, little attention has been paid to the study of preventing the elution of intercellular lipids during washing, but recently, a detergent composition that suppresses the elution of intercellular lipids has also been studied. Patent Document 3 proposes a composition containing an anionic surfactant and a polyoxyethylene sorbitan monolauric acid ester, which is an amphoteric surfactant and a nonionic surfactant, in a specific ratio.

Japanese Unexamined Patent Publication No. 2012-72399 Japanese Unexamined Patent Publication No. 2013-87095 Japanese Unexamined Patent Publication No. 2016-8206 Fragrance Journal 8, 21-25 (2012)

However, the surfactants used in the detergent composition have different actions on stratum corneum cells and intercellular lipids, respectively. The detergent compositions of Patent Documents 1 and 2 and Non-Patent Document 1 are excellent in sebum cleaning, but are not sufficient in terms of suppressing the elution of intercellular lipids. Further, the detergent of Patent Document 3 needs to contain a large amount of nonionic surfactant, which causes a decrease in the amount of foam. Foam performance such as rich foam volume is an important factor that evokes a feeling of cleansing during use, and conventional techniques suppress the elution of intercellular lipids to give mildness to the skin and rich foam volume. Achievement of both was not achieved.

We have found that amphoteric surfactants used to improve foam volume and quality in skin cleansing compositions are more cellular than anionic surfactants, which are the main cleansing and foaming bases. It was found that it is easy to elute the interstitial lipid.
Then, under conditions containing such a surfactant that elutes intercellular lipids, a diligent study was conducted to suppress the outflow of intercellular lipids. As a result, an interface that elutes intercellular lipids into a specific nonionic surfactant It was found that it has the effect of remarkably suppressing the influence of the activator. Specifically, a composition in which a specific nonionic surfactant and an anionic surfactant are combined in a specific ratio together with an amphoteric surfactant provides cells while maintaining a rich foam amount (foaming property). The present invention has been completed by finding that the elution of interfacial lipids can be suppressed.

(Evaluation method of intercellular lipid elution amount)
After weighing 49 mg of ceramide II (manufactured by Takasago International Corporation), 21 mg of palmitic acid (manufactured by Sigma Aldrich), and 32 mg of cholesterol (manufactured by Sigma Aldrich), 4 mL of chloroform / methanol = 2/1 (v / v). ) Was added, and the obtained solution was stirred at 30 ° C. for 1 hour to dissolve it.

(Evaluation method of foam amount)
About 30 g of hot water at 40 ° C. was soaked in about 20 g of hair bundle, 1 g of each composition and 0.2 ml of model sebum shown in Table 2 were applied, and the amount of foam was measured when the hair was whipped 60 times in 30 seconds.

From the results of Tables 1 to 5, in the detergent compositions of Examples 1 to 25, the elution of the intercellular lipid model was suppressed to a small extent and the amount of foam was large, so that the intercellular lipids were mild and rich. It was a composition that achieved both the amount of foam and the amount of foam.
Further, when Example 1 and Comparative Examples 1 and 2 are compared, Comparative Example 1 in which (A) / (B) is small has a small amount of bubbles, and Comparative Example 2 in which the ratio (A) / (B) is large is nonionic. Intercellular lipids were eluted as in the case without the sex detergent. The nonionic surfactant (polyoxyethylene (3) lauryl ether) blended in Comparative Example 5 has a large elution of intercellular lipids, and the nonionic surfactant (polyoxy) blended in Comparative Examples 6 and 7 has a large elution. In the case of polyethylene (80) sorbitan monolauric acid ester), not only the elution into the intercellular lipid was large, but also the amount of foam was reduced.
Based on the above, the nonionic surfactants blended in Examples 1 to 25 can sufficiently suppress the elution of intercellular lipids even with a small blending amount, so that the elution of intercellular lipids is suppressed and the skin is mild. However, it was possible to provide a comfortable cleaning feeling during use due to the rich amount of foam.

A detergent composition having the composition shown in Example 26 was produced in the same manner as in Examples 1 to 25.
When the hair was washed with the obtained washing composition, it was excellent in foaming and washing power, had a mild feeling on the scalp, and the elution of intercellular lipids was sufficiently suppressed.
