Description

  The present invention relates to a composition for a skin cleanser.

  Traditionally, skin cleansing agents such as shampoos, body soaps, cleansings, and facial cleansing agents not only remove dust and dirt on the skin and hair, but also remove sebum stains such as the scalp, face, and body. Expected to be effective. In order to remove sebum dirt, various surfactants have been used in conventional skin cleansing agents from the viewpoint of solubility with sebum and a feeling of use.

  Specifically, a sebum selective removing agent containing a hydrophilic surfactant and ethanol (see Patent Document 1), an anionic surfactant, an amphoteric surfactant, and a nonionic surfactant are specified. Scalp cleanser containing monohydric alcohol (see Patent Document 2), sebum remover composition containing inorganic salt, nonionic surfactant and cationic surfactant (see Patent Document 3), Gel-like skin cleanser containing hydrophilic polyglycerin fatty acid ester, acrylic polymer and alkylpolyglucoside (see Patent Document 4), specific anionic surface activity having a function of selectively removing sebum squalene Agent, specific amphoteric surfactant, detergent composition containing at least one nonionic surfactant (see Patent Document 5), anionic surfactant and cationic polymer A skin cleanser composition containing an oil agent (see Patent Document 6), a composition for removing skin stains containing a polyglycerin fatty acid ester having specific physical properties (see Patent Document 7), a polyoxyalkylene alkyl ether sulfate A hair cleansing composition containing a salt, a betaine-type amphoteric surfactant, a specific cationic polymer, an inorganic salt, and a specific polyglycerin fatty acid ester (see Patent Document 8) has been proposed.

  On the other hand, it is known that the composition of sebum components secreted from the skin changes with age. Furthermore, it is said that changes in the sebum component that is secreted affect the “stickiness” and “glare” of the skin and hair. Removal of sebum components secreted from the skin is effective for suppressing such “stickiness” and “glare” peculiar to middle-aged and elderly people. However, none of the skin cleansing agents aimed at removing sebum that has been studied so far can sufficiently satisfy the removal effect on specific sebum components secreted by middle-aged and older people. It was.

(Sample preparation)
According to the composition described in Tables 2-4, each composition for skin cleansing agents of Reference Examples 1-6, Examples 7-10, and Comparative Examples 1-6 was prepared, and it used for the following evaluation. The results are also shown in Tables 2-4. In addition, all evaluation was implemented on the constant conditions of constant temperature and humidity of 23 degreeC and 60% of humidity. Moreover, POE in the table is an abbreviation for polyoxyethylene, and the numerical value in parentheses represents the number of added moles of ethylene oxide.

(Test Example 1: Evaluation of cleaning removal)
Each sample of the reference example, the example and the comparative example was dissolved in purified water so as to have a concentration of 7% by mass to obtain an aqueous solution for washing test.

  The artificial sebum model shown in Table 1 was liquefied by heating to 60 ° C., and 0.25 g of the artificial sebum model was uniformly applied to a keratin cloth (20 mm × 20 mm). The keratin cloth after application of the artificial sebum model was allowed to stand at 35 ° C. for 12 hours or more.

Next, the prepared keratin cloth after application of the artificial sebum model was immersed in a container containing 100 mL of the aqueous solution for cleaning test previously maintained at 45 ° C. The keratin cloth after application of the artificial sebum model was washed by shaking the container for 60 minutes under the conditions of a vibration frequency of 60 cm ⁻¹ and an amplitude of 15 mm.

  The artificial sebum model remaining on the washed keratin cloth was extracted with chloroform. The obtained extract was subjected to gas chromatography with a flame ionization detector (GC-FID) under the following analysis conditions, and peaks corresponding to components (fatty acid, squalene, wax ester or triglyceride) contained in the artificial sebum model were measured. The area (hereinafter referred to as “area A”) was determined.

  Further, except that the artificial sebum model attached to the keratin cloth before washing was used instead of the artificial sebum model remaining on the washed keratin cloth, the same operation as described above was performed, and the peak area corresponding to the component (Hereinafter referred to as “area B”).

<Analysis conditions>
Apparatus: Agilent 6890N (manufactured by Agilent Technologies)
Column: Ultra ALLOY UA-DX30 (manufactured by Frontier Laboratories)
Carrier gas: Helium inlet temperature: 360 ° C
Column temperature: 40 ° C. to 20 ° C./min and held at 400 ° C. for 12 minutes Column flow rate: 2 mL / min Detector: Flame ionization detector (FID)
Detector temperature: 250 ° C
Injection volume: 2 μL

  Next, the residual rate of the lipid [(area A / area B) × 100] (%) was calculated from the obtained analysis result. Based on the calculation result of the residual rate, it evaluated according to the following evaluation criteria.

<Evaluation criteria for cleaning removal>
◎: The residual ratio of lipid in the keratin cloth after washing is 0% or more and less than 40% ○: The residual ratio of lipid in the keratin cloth after washing is 40% or more and less than 60% △: The lipid remaining in the keratin cloth after washing Residual rate is 60% or more and less than 90% x: The residual rate of lipid in the keratin cloth after washing is 90% or more

From the results shown in Tables 2 to 4, the composition for the skin cleanser of the present invention described in each Reference Example and each Example is excellent in cleaning and removing the specific sebum component secreted from middle-aged and elderly people. It can be seen that the effect is achieved. In other words, it can be said that the composition for skin cleanser of the present invention suppresses “stickiness” and “glare” peculiar to middle-aged and elderly people. On the other hand, in the comparative example that does not satisfy the configuration of the present invention, it is inferior to washing and removing sebum components, so it can be said that the “stickiness” and “glare” peculiar to middle-aged and elderly people cannot be sufficiently suppressed. .
