Description

  The present invention relates to a sebum soil removing agent having an excellent sebum removing effect and high moisturizing power, and a skin cleansing cosmetic containing the same.

  In recent years, not only women but also men have increased the awareness of care for sweat, sebum and body odor, and the market for skin cleansing agents has expanded. A lot of detergents such as facial cleansers, body cleaners, and shampoos are on the market. Furthermore, wiping lotions, sprays, and sheet-like skin cleansing cosmetics that can remove sweat and sebum can be easily used even when going out, so their use is being widely used regardless of age, gender, and season.

As a sheet-like skin cleansing cosmetic, for example, a nonionic surfactant and a polyhydric alcohol or a polyhydric alcohol for the purpose of having high cleanability against makeup and sebum stains, low irritation to skin, and excellent operability and stability. A skin cleaning sheet containing glycol ether and water is known (Patent Document 1).
Furthermore, it has high detergency to sebum and makeup stains and contains polyoxyethylene glycerin fatty acid ester and / or polyoxyethylene glycol fatty acid ester, lactic acid, phenoxyethanol and / or benzoic acid or its salt, and water. There is disclosed a skin cleaning sheet (Patent Document 2) and the like which are free from rough skin and have excellent antiseptic stability.

  In these techniques, makeup and sebum dirt are targeted for removal based on the concept of oil-soluble dirt. In general, compared with wax esters, squalene, triglycerides, etc. that make up sebum, makeup products contain a lot of special ingredients such as silicone-based and fluorine-based oils and surfactants in order to give them more resistance to sweat and sebum. However, there is a problem that makeup stains and sebum stains are completely different in terms of their components and physical properties. In addition, by using a large amount of cleaning agent with higher cleaning power than necessary, men and children who do not make up will remove excessive sebum, causing unnecessary skin roughness, skin dryness, fine lines, etc. There was a problem that caused trouble.

  The object of the present invention has been made in view of the above-mentioned problems of the prior art, and the object thereof is a sebum soil removing agent having an excellent effect of removing sebum soil and having a high moisturizing power, and a skin cleaning composition containing the same. Cosmetics will be provided.

As a result of intensive studies by the present inventors in order to achieve the above-mentioned object, it is possible to contain a specific polyoxyethylene polyoxypropylene glyceryl ether, a specific HLB10 or higher nonionic surfactant, and water. The present inventors have found that a sebum soil removing agent having an excellent removal effect on sebum and having a high moisturizing power can be obtained, and the present invention has been completed.
That is, the present invention relates to (A) polyoxyethylene polyoxypropylene glyceryl ether having an average addition mole number of oxyethylene groups of 1 to 100 and an average addition mole number of oxypropylene groups of 1 to 50, (B) POE- 1 selected from sorbitan fatty acid ester, POE-sorbite fatty acid ester, POE-glycerin fatty acid ester, POE-POP-alkyl ether, POE-castor oil or hydrogenated castor oil derivative, polyglycerin fatty acid ester, alkanolamide, POE-alkyl ether A sebum soil remover comprising: a nonionic surfactant having two or more HLBs of 10 species or more, and (C) water. Furthermore, it is a skin cleansing cosmetic compounded with this, and further a skin cleansing sheet cosmetic impregnated with a sheet base.

  According to the present invention, there is provided a sebum stain removing agent having an excellent sebum stain removing effect and having a high moisturizing power, a skin cleansing cosmetic compounded with the same, and a skin cleansing sheet cosmetic impregnated in a sheet base. Can be provided.

Hereinafter, preferred embodiments according to the present invention will be described in detail.
In the following, polyoxyethylene is sometimes abbreviated as POE, and polyoxypropylene is sometimes abbreviated as POP.
The polyoxyethylene polyoxypropylene glyceryl ether (A) used in the present invention has an average addition mole number of oxyethylene groups of 1 to 100 and an average addition mole number of oxypropylene groups of 1 to 50. Further, the order of adding ethylene oxide and propylene oxide is not particularly limited, and the ratio of the oxyethylene group to the total of the oxyethylene group and the oxypropylene group is not particularly limited.
The average added mole number of the oxyethylene group is 1 to 100, preferably 3 to 75, and more preferably 5 to 50. If the average added mole number of the oxyethylene group is too small, blending into an aqueous preparation becomes difficult, and if it is too large, stickiness may be strongly felt. Moreover, the average addition mole number of the said oxypropylene group is 1-50, Preferably it is 3-45, More preferably, it is 5-40. If the average number of added moles of oxypropylene group is too small, the effect of removing sebum will be low, and if it is too high, it may be difficult to formulate in an aqueous preparation.

In addition, the polyoxyethylene polyoxypropylene glyceryl ether (A) of the present invention may have an oxyethylene group and an oxypropylene group added in a block shape or in a random shape, but may be added in a block shape. It is preferable that Polyoxyethylene polyoxypropylene glyceryl ether can also be produced by a known method. Specifically, ethylene oxide and propylene oxide are subjected to addition polymerization at 130 to 160 ° C. with respect to glycerol under an alkali catalyst. It is obtained by.
The polyoxyethylene polyoxypropylene glyceryl ether of the present invention may be a commercially available product, for example, NIKKOL SG-G2424 (manufactured by Nikko Chemicals), Unilube 50TG-32 (manufactured by NOF Corporation), Adeka Carpol GH-200 (ADEKA) New Paul GET-2800 (manufactured by Sanyo Chemical Industries) can be used.

The content of (A) polyoxyethylene polyoxypropylene glyceryl ether of the present invention is preferably 1 to 20% by mass, more preferably 5 to 15% by mass in the total amount of the sebum soil removing agent. Within such a range, the effect of removing sebum dirt can be suitably exhibited.
Usually, the polyoxyethylene polyoxypropylene glyceryl ether is mainly used as a humectant in general cosmetics. Therefore, in order to satisfy the effect as a moisturizing agent, the blending amount is usually less than 5% by mass with respect to the total amount of the cosmetic. However, an excellent sebum removing effect can be exhibited by blending polyoxyethylene polyoxypropylene glyceryl ether in an amount greater than usual.

The nonionic surfactant having component (B) HLB of 10 or more used in the present invention is POE-sorbitan fatty acid ester, POE-sorbite fatty acid ester, POE-glycerin fatty acid ester, POE / POP-alkyl ether, POE-castor oil Or it is 1 type, or 2 or more types chosen from hydrogenated castor oil derivative, polyglycerin fatty acid ester, alkanolamide, and POE-alkyl ether. These nonionic surfactants are preferable in terms of enhancing the effect of removing sebum dirt, and nonionic surfactants of less than HLB10 are less irritating to the skin, but suppress the sebum dirt effect and become sticky during application. Is felt and stability is also deteriorated.
Content of the nonionic surfactant of the component (B) in this invention is 0.1-5 mass% in a sebum dirt remover, Preferably, it is 0.2-1 mass%.

In the sebum stain removing agent of the present invention, in addition to the above components, various components that are usually used in cosmetics, for example, oily components, higher alcohols, polar oils, active ingredients, moisturizing agents, as long as the effects of the present invention are not impaired. Ingredients, antibacterial ingredients, viscosity modifiers, pigments, fragrances and the like can be blended and manufactured according to conventional methods.
As a method of blending the above-mentioned components into the sebum stain remover of the present invention, the polyoxyethylene polyoxypropylene glyceryl ether used in the present invention is arbitrarily dissolved in water, so a special operation or machine should be used. However, it can be easily mixed by a conventional method using a paddle mixer or the like.

  Examples of the form of the sebum stain remover of the present invention include water-based, oil-in-water lotions, essences, gels, milks, and the like. Examples of skin cleansing cosmetics containing the sebum stain removing agent of the present invention include facial and body wiping lotions, mists, sprays, and sheet cosmetics obtained by impregnating a sheet base with a sebum stain cleaning agent. In particular, it is suitably used for sheet cosmetics.

Although it does not specifically limit as a sheet base used for the said sheet cosmetics, it is a sheet-like base material which can be impregnated with the sebum dirt removing agent of this invention, and a woven fabric and a nonwoven fabric are preferable. More specifically, it is a laminate of woven fabric or non-woven fabric, natural fibers are cotton, pulp, silk, cellulose, hemp, etc., and synthetic fibers are polyesters such as polyethylene terephthalate, polybutylene terephthalate, polypropylene, polyethylene, etc. Examples of semi-natural fibers such as fibers and polyolefin fibers include rayon and acetate.
The impregnation rate of the sebum soil removing agent with respect to the sheet base is preferably 50 to 1000%, more preferably 300 to 700% from the viewpoint of the sebum soil removing effect and the feeling of use.
