Description

[Technical field]

[0001] The present invention relates to a skin or hair cleansing composition. [Background technology]

[0002] In skin cleansing compositions, a large amount of anionic surfactants are used as surfactants with excellent cleansing power and foaming properties in order to achieve excellent cleansing power and a large amount of foam. When anionic surfactants are repeatedly used on the skin, components that should be left on the skin may be washed away, so they are required to have excellent cleansing power and foaming power as well as be mild to the skin. For example, Patent Document 1 describes that a liquid detergent composition containing an N-acyl acidic amino acid or a salt thereof, an alkyl ether carboxylic acid or a salt thereof, an amphoteric surfactant and water has high foaming performance, leaves the skin feeling smooth and protected after washing, and reduces irritation to the skin caused by washing. Research is also underway into the effects of skin cleansers on the stratum corneum. The components of the stratum corneum are stratum corneum cells and intercellular lipids, and it is known that stratum corneum cells play a role in retaining moisture inside the skin and protecting it from external stimuli. For this reason, various methods have been investigated to keep natural moisturizing components such as amino acids contained in stratum corneum cells within the cells, but the relationship between intercellular lipids and skin cleansers has not received much attention. In recent years, studies have been conducted focusing on intercellular lipids, which are important for the barrier function of the stratum corneum. For example, a cleanser composition that suppresses the elution of intercellular lipids has been studied (Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-48348 A [Patent Document 2] JP 2016-8206 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the surfactants used in cleansing compositions have different effects on stratum corneum cells and intercellular lipids, and therefore conventional cleansing compositions, even if they were able to protect stratum corneum cells, were unable to sufficiently suppress the elution of intercellular lipids and were therefore insufficient in terms of mildness to the skin. [Means for solving the problem]

[0005] The present inventors have discovered that amphoteric surfactants, which are used primarily to improve foam quality in skin cleansing compositions, contribute more to the elution of intercellular lipids than anionic surfactants, which are the main cleansing and foaming agents. Then, under the condition containing such a surfactant that elutes intercellular lipids, the inventors conducted extensive research to suppress the outflow of intercellular lipids, and found that a specific nonionic surfactant has the effect of suppressing the effect of the surfactant that elutes intercellular lipids. Specifically, the inventors found that a composition that combines an amphoteric surfactant with a specific nonionic surfactant and an anionic surfactant in a specific ratio can suppress the elution of intercellular lipids while maintaining a rich foam volume, and thus completed the present invention.

[0006] The present invention comprises the following components (A), (B) and (C): (A) an amphoteric surfactant, (B) a polyoxyethylene sorbitan fatty acid ester or a polyoxyethylene sorbitol fatty acid ester, in which the average number of moles of ethylene oxide added is 3 to 10 when the fatty acid residue has 12 to less than 16 carbon atoms, and the average number of moles of ethylene oxide added is 3 to 80 when the fatty acid residue has 16 to 22 carbon atoms; (C) Anionic surfactants Contains The mass ratio (C) / (B) of the component (C) to the component (B) is 4 to 100; The content of (C2) alkyl sulfate or polyoxyalkylene alkyl ether sulfate in component (C) is 60 mass% or less, The present invention relates to a skin or hair cleansing composition having a polyhydric alcohol content of 12% by mass or less.

[0007] The present invention also provides a composition comprising (A) an amphoteric surfactant and (C) an anionic surfactant, (B) a polyoxyethylene sorbitan fatty acid ester or a polyoxyethylene sorbitol fatty acid ester, in which the average number of moles of ethylene oxide added is 3 to 10 when the fatty acid residue has 12 to less than 16 carbon atoms, and the average number of moles of ethylene oxide added is 3 to 80 when the fatty acid residue has 16 to 22 carbon atoms, The present invention relates to a method for inhibiting the elution of intercellular lipids, which comprises adding component (C) to component (B) so that the mass ratio (C) / (B) of component (C) to component (B) is 4 to 100.

Moreover, from the viewpoint of suppressing the elution of intercellular lipids, the content of the betaine acetate surfactant in component (A) is preferably 3% by mass or less.

From the viewpoint of achieving both blend stability and suppression of elution of intercellular lipids, when the fatty acid residue has less than 12 to 16 carbon atoms, the average number of moles of ethylene oxide added is preferably 4 to 10, more preferably 5 to 9. Furthermore, from the viewpoint of further suppressing elution of intercellular lipids, when the fatty acid residue has 16 to 22 carbon atoms, the average number of moles of ethylene oxide added is preferably 3 to 60, more preferably 6 to 60. Furthermore, the fatty acid residue preferably has 14 to 22 carbon atoms, and more preferably has 16 to 22 carbon atoms.

[0014] In the present invention, in order to maintain the cleaning power and foaming power, many components that promote the elution of intercellular lipids are included, but the elution of intercellular lipids is suppressed.

As a result, it is presumed that these components are inhibited from penetrating into the intercellular lipids, and the elution of intercellular lipids is suppressed.

EXAMPLES

[0047] Test Example 1 Cleaning compositions having the compositions shown in Table 1 were prepared and evaluated for foaming (foam volume). The results are also shown in Table 1. The numbers in the table for the blend amounts indicate effective amounts.

[0048] (Manufacturing method) Components (A), (B), (C) and other components were added and stirred, and the pH was adjusted to the specified level using potassium hydroxide and citric acid. The mixture was stirred until homogenous and then cooled to 30°C to obtain each composition.

[0049] (Evaluation method) 15 g of each composition was placed in a beaker and diluted with 135 g of tap water at 40°C. The solution was placed in a hand blender (Panasonic, MX-X-301-R fiber mixer) and stirred for 10 seconds in high speed mode. The solution after stirring was placed in a 1000 mL graduated cylinder and left to stand for 2 minutes. The height of the foam and the height of the liquid surface after 2 minutes were read, and the foam volume was calculated according to the following formula. Foam volume (mL) = (foam height) - (liquid level)

[0050] [Table 1]

[0051] The results in Table 1 show that when (C) / (B) is less than 4, the amount of foam is insufficient.

[0052] Test Example 2 (Sebum Residual Rate) Cleansing compositions having the compositions shown in Table 3 were prepared in the same manner as in Test Example 1, and the sebum residual rate was evaluated. The results are also shown in Table 3.

[0053] (Evaluation method) A circle with a diameter of 4.0 cm was marked on the inner side of the forearm as the test site. The L value was measured in advance using a color difference meter (color difference meter CR-400, Konica Minolta) to determine the skin color of the test site. Carbon black was dispersed at 2% by mass in the surface sebum model shown in Table 2, which was dissolved in a water bath at 50°C, and 10 mg of the carbon black was uniformly applied to the test site. After leaving it for 15 minutes, the color was measured using a color difference meter. Each composition was placed into a pump former (manufactured by Yoshino Kogyo Co., Ltd., two sheets of 305 mesh size) that dispenses when the pump head is pressed, and 1.0 g (one push) of foam was placed on the test area, which was then massaged and washed 20 times with the tip of the index finger, and then rinsed off with tap water. After 5 minutes, the skin color after washing was measured, and the residual rate of the model sebum remaining on the skin was calculated using the following formula.

[0055] [Table 2]

[0056] [Table 3]

[0057] The results in Table 3 show that when the proportion of (C2) in component (C) exceeds 60 mass %, the sebum residual rate is high and the cleansing properties are insufficient.

[0058] Examples 1 to 24, Comparative Examples 1 to 3 Detergent compositions having the compositions shown in Tables 4 to 6 were prepared in the same manner as in Test Example 1, and the amount of cholesterol eluted was evaluated using an intercellular lipid model. The results are also shown in Tables 4 to 6.

[0059] (Evaluation method) 49 mg of ceramide (Takasago International Corporation), 21 mg of palmitic acid (Sigma-Aldrich Corporation), and 32 mg of cholesterol (Sigma-Aldrich Corporation) were weighed, and then 4 mL of chloroform / methanol = 2 / 1 (v / v) was added to the mixture, and the resulting solution was stirred at 30 ° C for 1 hour to dissolve. The solvent was removed under a nitrogen atmosphere, and the resulting powder was dried overnight under reduced pressure to obtain an intercellular lipid model. 10 mg of the resulting intercellular lipid was weighed out and placed in a vial, and 5 ml of a 10-fold dilution of each composition was added and stirred at 32 ° C for 1 hour. After the test, the supernatant was collected, and a solution containing the eluate from the intercellular lipid model was obtained as an eluate. 400 μL of methanol (Fujifilm Wako Pure Chemical Industries, Ltd.) and 500 μL of chloroform (Fujifilm Wako Pure Chemical Industries, Ltd.) were added to 100 μL of the resulting eluate to obtain a solvent mixture.
