Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cleansing composition containing a high amount of oil,

The present invention relates to a hair cleansing composition, and more particularly, to a hair cleansing composition which contains a high content of an oil by adding a polyol in a proper proportion, maintains a transparent appearance of the formulation, and provides softness and luster to the hair .

The primary purpose of hair cleansing is to keep the hair clean and healthy. In recent years, however, there has been a growing demand for improved hair due to multiple causes such as diversification of customers, improvement of income level, stress, and change of living environment. Therefore, in recent years, there is a growing demand for a composition for cleaning hair which improves softness of hair and provides shine to hair.

Oils are cosmetic ingredients that are often used to soften and shine hair. Oils are used not only in leave-on products such as hair serum, hair oil, and hair essence but also in washing products such as rinses, conditioners, treatments and hair packs for hair because of their excellent effects. However, adding more than 1% of oil to shampoo makes the shampoo formulation unstable and difficult to keep the formulation transparent, so the shampoos so far do not contain high amounts of oil and contain only very small amounts of less than 1% .

The polyol may be a C ₃ -C ₁₅ alkane polyol and may specifically be a C ₃ -C ₁₅ diol, a C ₃ -C ₁₅ triol, or a C ₃ -C ₁₅ tetrol, and a hydroxyl group (OH And the number of the groups. More specifically, at least one selected from the group consisting of dipropylene glycol, hexanediol, heptanediol, heptanediol, octanediol, nonanediol, and glycerin may be used, but is not limited thereto. The polyol may be contained in an amount of 10 to 50% by weight, and preferably 10 to 30% by weight based on the total weight of the composition. If the polyol is contained in an amount of less than 10% by weight, the solubilization effect and moisturizing effect of the oil are insufficient. If the polyol is contained in an amount exceeding 50% by weight, there is a problem of skin stability or shape.

The surfactant may be an anionic surfactant or a zwitterionic surfactant, because it has better washing power and superior foaming power as compared to a nonionic / cationic surfactant. Specifically, the anionic surfactant may be selected from the group consisting of sodium laureth sulfate, sodium lauryl sulfate, ammonium laureth sulfate, and ammonium lauryl sulfate. But the present invention is not limited thereto, and the amphoteric surfactant may be cocamidopropyl betaine or cocamidopropyl hydroxy ketone. The surfactant may be contained in an amount of 5 to 50% by weight, and preferably 20 to 40% by weight based on the total weight of the composition. If the surfactant is contained in an amount of less than 5% by weight, the solubilizing effect and cleaning effect of the oil are insufficient. If the surfactant is contained in an amount exceeding 50% by weight, there is a problem of skin stability or shape.

Hereinafter, the present invention will be described in more detail with reference to Examples and Test Examples. However, it will be apparent to those skilled in the art that the present invention is not limited to these Examples and Test Examples, and can be applied to hair related products in general.

[Reference Example 1] Production of shampoo of Comparative Examples 1 to 6 and Examples 1 to 3

The shampoos of Examples and Comparative Examples were prepared in a conventional manner according to the composition shown in Table 1 below (unit: wt%). The surfactant used was ammonium laureth sulfate, the polyol used was glycerin, and the oil used was 2-octydododecanol. The manufacturing process was as follows.

Ammonium laureth sulfate was added to 10% water. After that, glycerin and 2-octydodecanol were added to each of the components and mixed thoroughly for 10 minutes or more using a stirrer (National SS motor SSC811CA, Shin-Industrial Machinery Co., Ltd.) . In order to eliminate the effect of bubbles generated during the manufacturing process on the transparency, the manufactured samples are left at room temperature for 3 hours and then observed and measured.

 [Test Example 1] Evaluation of transparency of a formulation

In order to observe the transparency of the formulations of Comparative Examples 1 to 6 and Examples 1 to 3 described in Table 1, photographs were taken by placing paper with a letter written on the glass bottle containing the formulation, Respectively. In order to quantify the transparency, the transparency was measured using a spectrophotometer (UV-VIS Spectrophotometer UV0909M217, Varian). The results are shown in Table 2 (unit: transmittance, percent transmittance). The closer the value is to 100, the more transparent it is like water. The closer the value is to 0, the more turbid.

Transparency (% t) Comparative Example 1 100 Comparative Example 2 100 Comparative Example 3 100 Comparative Example 4 89 Comparative Example 5 83 Comparative Example 6 32 Example 1 98 Example 2 95 Example 3 100

As can be seen from Fig. 1, the formulation becomes opaque when the oil is contained at 1.0%, and when the oil is contained at 5.0%, the formulation is completely cloudy. However, when the polyol is added at 10.0%, it can be seen that the formulation is kept transparent even when the oil is contained at 5.0% as shown in FIG. Therefore, it was confirmed that when the polyol was added in an appropriate ratio, the transparent appearance of the formulation could be maintained while containing the oil in a high content.

As can be seen from Comparative Examples 4 to 6 of Table 2, the transparency was lowered as the content of oil increased, and in particular, when the oil content was 5.0% (Comparative Example 6), turbidity was remarkably observed . However, even when the oil was contained in a high content, it was confirmed numerically that the transparent appearance of the formulation was retained when the polyol was added (Examples 1 to 3).

[Test Example 2] Evaluation of softness of hair

In order to evaluate the softness of the hair, the shampoo was prepared in Comparative Examples 1 to 6 and Examples 1 to 3 described in Table 1, and then the force applied when combing the hair was measured. The results are shown in Table 3 and FIG. At this time, the smaller the force applied, the smoother the hair.

Dry Comb Load Comparative Example 1 129.6 Comparative Example 2 129.3 Comparative Example 3 128.4 Comparative Example 4 123.2 Comparative Example 5 112.2 Comparative Example 6 100.1 Example 1 90.7 Example 2 80.5 Example 3 78.6

In the results of Table 3 and FIG. 3, in the case of shampooing as an example, it was confirmed that the force to be applied when combing hair was significantly smaller than that of shampooing as a comparative example, I could. Therefore, it was confirmed that the shampoo containing the oil in a high content improves the softness of the hair.

 [Test Example 3] Evaluation of gloss of hair

In order to evaluate the shine of the hair, shampoos were prepared in Comparative Examples 1 to 6 and Examples 1 to 3 described in Table 1, and gloss was measured by hair tress. The results are shown in Table 4 and FIG. At this time, the larger the Luster value, the better the hair shine.

Luster value Comparative Example 1 2.87 Comparative Example 2 2.85 Comparative Example 3 2.99 Comparative Example 4 3.15 Comparative Example 5 3.52 Comparative Example 6 3.96 Example 1 4.08 Example 2 4.35 Example 3 4.37

From the results of Table 4 and FIG. 4, it can be seen that the luster value was larger in the case of shampooing as an example than in the case of shampooing as an example, and the luster value was increased depending on the oil concentration. Therefore, it was confirmed that the shine of the hair containing the high amount of oil improves the shine of the hair.

From the above results, it has been confirmed that by adding the polyol at a proper ratio, the oil can be contained in a high content and at the same time, the formulation can be kept transparent and the softness and the gloss can be improved in the hair.
