Description

Nonaqueous cosmetic composition for scalp cleaning {Nonaqueous cosmetic composition for cleansing scalp}

The present invention relates to a non-aqueous cosmetic composition for scalp cleaning, and specifically, has excellent ability to remove oily residues such as excessive sebum and residual styling agent of the scalp, is easily washed in water, and has a hair cleaning effect, thus using a separate shampoo. Not only does this need, but it relates to the non-aqueous cosmetic composition for scalp cleaning which gives a softness to hair.

Cleansing to care for the skin and scalp is very important. Particularly, in the case of oily scalp, sebum accumulates in the scalp and accumulates in the hair follicles, it becomes a food of dandruff and causes dandruff and itching, and in severe cases, hair loss may be caused by inhibiting hair growth in the hair follicles.

Shampoos for oily scalp and hair cleaning are commercially available, but there is not enough to remove sebum accumulated in the scalp and pores, and scalp care products that remove pore wastes and dead skin through scalp massage are used. These scalp care products are applied to the hair before shampooing, rinsed with water and then rinsed again with shampoo, and are classified into oil type and emulsion type.

The oil type uses almost 100% oil to remove oily residues, but since it uses only oil, it is sticky and not very comfortable to use, and oil remains on the scalp and hair after use. There is a hassle to use and wash off.

In the case of the emulsion type, the cationic surfactant and the oily component are used to make it easier to wash with water than the oil type, but the cleaning power is weak and there are still many residues on the scalp and hair.

Japanese Patent No. 3828301 proposed a scalp detergent containing a specific ratio of surfactant, ethanol and antidandruff, but the hair was severely stiff and the sebum removal effect was not high when used after washing.

Korean Patent Publication No. 10-2008-0049173 proposes a cosmetic composition containing two or more of papain enzyme capsules, jojoba oil beads, and imidazole as active ingredients to seek waste and exfoliation of the scalp pores. As a composition comprising an active ingredient of the exfoliating effect in the shampoo and conditioner formulation, only the exfoliating performance is mainly desired, and the effect of removing the oily residue is not mentioned.

Korean Patent Publication No. 10-2005-0087061 proposes a cosmetic composition containing a polyglycerol fatty acid ester, a liquid oil and a moisturizer, but it is excellent in removing oily residues and rinsing only when used on skin. When used on the scalp, the oil is attached to the hair, which is a hassle.

In order to solve the above problems, an object of the present invention is excellent in the ability to remove oily residues such as excessive sebum and residual styling agent of the scalp, easily washed with water and even hair cleaning effect, and does not require the use of a separate shampoo, It is to provide a non-aqueous cosmetic composition for scalp cleaning to impart softness to the hair.

As shown in Table 3, the non-aqueous cosmetic composition of Examples 1 to 7 was maintained in a transparent appearance without problems such as phase separation and precipitation even after storing for 30 days at room temperature, high temperature. On the other hand, as shown in Table 4, the composition of the comparative example was confirmed that there is a problem in the formulation stability, such as phase separation when stored in the same conditions.

< Experimental Example  2> Sebum removal performance evaluation

0.5 g of the compositions of Examples 1 to 7 and Comparative Examples 2 and 4, which had good formulation stability in Experimental Example 1, were evenly applied to sebum stain wool (WS-32-003, center For Testmaterials, Inc.), and then Terg- After cleaning sebum stain with O-Tometer (25 ℃, 1L of water, 2 minutes of washing time, rpm 120), change the whiteness by calculating the difference of delta value using Whitness measuring device (Minolta colorimeter). Was measured, and the results are shown in Table 5 below.

As shown in Table 5, Examples 1 to 7 showed excellent sebum removal effect, in the case of the composition of Comparative Example 2 does not contain an anionic surfactant was confirmed that the sebum removal performance is much lower.

< Experimental Example  3> Feeling  evaluation: Rinseability  And hair softness

In order to evaluate the rinsing properties and softness of the hair, 100 women in their 20s to 40s were selected to use the products containing the compositions of Examples 1 to 7 and Comparative Examples 2 to 4 once daily for 2 weeks, and then the following evaluations were made. Evaluation was made according to the standard, and the results are shown in Table 6 below.

- Evaluation standard -

1: very bad, 2: bad, 3: moderate, 4: good, 5: very good

Item Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Example 7 Comparative Example 2 Comparative Example 3 Comparative Example 4 Rinseability 4.8 4.7 4.8 4.1 4.1 4.9 4.8 2.0 4.2 4.5 Hair softness 4.0 4.1 3.8 4.2 4.2 3.6 4.5 3.0 2.4 1.6

According to the said Table 6, Examples 1-7 received all the favorable evaluation in rinse property and hair softness than Comparative Examples 2, 3, and 4. In the case of the cosmetic composition of Comparative Example 2 that does not contain an anionic surfactant, both the rinsing property and the hair softness showed poor results, and the composition of Comparative Example 3 using the anionic surfactant in excess and the alkoxylated alcohol citrate in the excess In the case of the composition of 4, the rinsing property is excellent but the hair softness is evaluated very poorly, it can be seen that the conditioning effect is lowered.

 As described above, the non-aqueous cosmetic composition for scalp cleaning of the present invention is stable even in the presence of an oily component in excess, and has an excellent ability to remove oily residues and wastes of the scalp by containing an oily component. In addition, since the non-aqueous cosmetic composition for scalp cleaning of the present invention is easily washed out with water, it is not necessary to use a shampoo separately and gives softness to the hair.
