Description

[0001] Cosmetic composition for cleansing scalp of W / O emulsion [0002]

The present invention relates to a cosmetic composition for cleansing the scalp of a W / O emulsion. More particularly, the present invention relates to a cosmetic composition for cleansing the scalp of a W / O emulsion which is excellent in the ability to remove oily residues of sebum of the scalp and styling agent, And more particularly to a cosmetic composition for cosmetics.

Cleansing the skin and scalp for care is very important. In particular, in the case of oily scalp, sebum accumulates on the scalp and accumulates in the hair follicle, which leads to dandruff and itching. In severe cases, it inhibits hair growth in the hair follicle, thereby causing hair loss.

Although oily scalp and shampoo for hair washing are commercially available, it is not enough to remove accumulated sebum on the scalp and pores. Thus, scalp care products that remove wastes and dead skin cells through the scalp massage are used. These scalp care products are divided into the oil type and the surfactant type, which are applied to the scalp before shampooing, rinsed with water and then rinsed again with shampoo.

In case of oil type, oily residue removal performance is excellent, but viscosity is low and there is a disadvantage that it flows down during use, and oil is hard to wash with water and scalp. Therefore, it is troublesome to wash using shampoo several times.

Surfactant type was designed to be easier to wash with water than oil type. However, there is a problem that the formulation is similar to shampoo and has weak detergency against oily residue and there is still a lot of residue in scalp and hair.

In order to solve the above problems, it is an object of the present invention to provide a cosmetic composition for cleansing the scalp of a W / O emulsion formulation which is excellent in the ability to remove oily residues of scalp sebum and styling agent, easily washed in water, .

In order to achieve the above object,

5 to 70 parts by weight of a dialkyl ester, a dialkyl ether, or a mixture thereof; 10 to 30 parts by weight of an emulsifier; 1 to 10 parts by weight of a polyhydric alcohol; And 10 to 20 parts by weight of purified water is provided in a cosmetic composition for cleansing the scalp of a W / O emulsion formulation.

The cosmetic composition for cleansing the scalp of the W / O emulsion formulation of the present invention is excellent in cleaning ability of oily residues and pores in the scalp, and is excellent in usability because it does not flow down during use.

In addition, the cosmetic composition for cleansing the scalp of the W / O emulsion formulation of the present invention is excellent in the stability of the formulation even though it contains a large amount of an oil component.

Figs. 3 and 4 are diagrams showing the evaluation results of the composition for improving the scalp keratin of the composition of Example 1. Fig.

Hereinafter, the present invention will be described in detail so as to be easily carried out by those skilled in the art.

The W / O emulsion cosmetic composition for scalp cleansing of the present invention comprises a dialkyl ether, a dialkyl ester, or a mixture thereof; Emulsifiers; Polyhydric alcohols; And purified water. The W / O emulsion cosmetic composition for scalp cleansing has excellent ability to remove oily residues of excess sebum and styling agent of the scalp, and is excellent in cleansing power.

The dialkyl ester imparts a feeling of silky feel to the scalp and hair that can be dried due to washing, and shows the effect of reducing irritation.

The dialkyl ester can be represented by the following formula 1 or 2:

[Chemical Formula 1]

R1 (CO) OR2

(2)

R3O (CO) OR4

(In the formulas (1) and (2), R 1 to R 4 are each independently a linear or branched, saturated or unsaturated alkyl group having 1 to 22 carbon atoms.)

Specific examples of the above-mentioned dialkyl esters include dioctylmaleate, propylheptylcycaprylate, isononyl isonanoate, di-fipi-2-methyl-10 adipate, dimethyl carbonate, diethyl carbonate, diethylhexyl carbonate, Propyl carbonate, and the like, but are not limited thereto.

The dialkyl ether has excellent wetting property and oily component and excellent dissolving power of oily residue, thus showing excellent performance in removing sebum from the scalp.

The dialkyl ether may be represented by the following formula (3): < EMI ID =

(3)

R5OR6

(Wherein R 5 and R 6 are each independently a linear or branched, saturated or unsaturated alkyl group having 1 to 22 carbon atoms)

Specific examples of the dialkyl ether include dimethyl ether, diethyl ether, ethyl methyl ether, dibutyl ether, dicaprylyl ether, diethylhexyl ether, dipropyl decyl ether and dibutyl cetyl ether. It is not.

The content of the dialkyl ester, dialkyl ether, or mixture thereof is preferably 5 to 70 parts by weight based on 100 parts by weight of the cosmetic composition. If the content is less than 5 parts by weight, the ability to remove oily residues of the sebum and styling agent of the scalp is poor. If the content is more than 70 parts by weight, the viscosity of the hair is difficult to increase.

The emulsifier has an advantage of solubilization effect and stability. The content of the emulsifier is preferably 10 to 30 parts by weight based on 100 parts by weight of the cosmetic composition. If the content is less than 10 parts by weight, the stability of the emulsion formulation is poor. If the content is more than 30 parts by weight, the fragrance is adversely affected.

The emulsifier may be a nonionic surfactant having a hydrophilic lipophilic balance (HLB) value of 14 or less. If the HLB value exceeds 14, the stability of the emulsion formulation containing the oil component is poor.

Specific examples of the emulsifier include polyoxyethylene-20 hydrogenated castor oil, polyoxyethylene-30 hydrogenated castor oil, polyoxyethylene-40 hydrogenated castor oil, polyoxyethylene-4 sorbitan monolaurate, Polyoxyethylene-6 sorbitan monooleate, polyoxyethylene-20 tristearate, polyoxyethylene-2 sorbitan trioleate, polyoxyethylene-30 sorbitol tetraoleate, polyoxyethylene-40 sorbitol tetraoleate Etc. may be used, and preferably a polyoxyethylene-40 hydrogenated castor oil is used.

The polyhydric alcohol improves the stability of the W / O emulsion and provides a smooth feeling after washing. The content of the polyhydric alcohol is 1 to 10 parts by weight based on 100 parts by weight of the cosmetic composition. If the content is less than 1 part by weight, the stability of the W / O emulsion can not be improved. If the content is more than 10 parts by weight, hair tends to stick after washing.

Specific examples of the polyhydric alcohol include at least one selected from the group consisting of glycerin, butylene glycol, propylene glycol, and polyethylene glycol.

The content of the purified water is 10 to 20 parts by weight based on 100 parts by weight of the cosmetic composition. When the purified water is used in an amount of less than 10 parts by weight, viscosity can not be formed. When it is used in an amount of more than 20 parts by weight, there is a disadvantage in that the formulation stability and washing power are poor.

The W / O emulsion cosmetic composition of the present invention may further include components commonly used in the manufacture of hair cosmetics such as moisturizers, fatty substances, wetting substances, perfumes, etc., well known in the art.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. This is for the purpose of illustrating the present invention, and thus the scope of the present invention is not limited thereto.
