Description

TECHNICAL FIELD [0001] The present invention relates to hair or scalp washing composition enhancing hair volume,

The present invention relates to a composition for hair or scalp, and more particularly, to a composition comprising polyquaternium-11 and a vinylimidazole copolymer blended in a specific ratio, thereby improving the volume of hair in addition to general cleaning action, And a hair or scalp cleansing composition in which the volume feeling of the posterior hair is improved.

In general, the hair is composed of a protein called keratin. Specifically, hair is a keratin protein containing 14 to 18% cystine among 18 kinds of amino acids. These keratin proteins are a very strong protein in mild conditions, such as water or neutral solvents, but can easily be damaged by excessive physicochemical treatments such as combing, dry heat, dyeing, perming, and the like. In recent years, due to various physical, chemical or environmental factors such as frequent perms, dyeing, etc., the hair is damaged, and the hair becomes rough and loses its gloss and the softness and softening effect are lowered. There is a problem that hair tends to become thin and elasticity is lost, and there is no volume feeling as it is struck.

To solve these problems, there has been continuous research on cosmetics to improve the softness of hair after washing or washing and to restore and strengthen damaged hair. As a result, various methods have been tried and developed and put into practical use in order to give a strong and continuous effect of hair conditioning.

Especially, hair or scalp cleansing compositions typified by shampoo usually have hair and scalp cleansing function. In recent years, however, various products having additional functions other than the original cleaning purpose have been introduced, Products that prevent the hair from falling off after drying the hair and improve the softness, and products for the purpose of arranging and repairing hair damaged by the hair treatment such as dyeing or polishing are being developed.

However, conventional products are advantageous for providing conditioning effects such as softness, moistness, flexibility, and combability of hair by the use of silicone, but when the hair is damaged and damaged, the hair is rather soaked and struck There is a problem in giving volume to the hair.

[Test Example 1] Evaluation of the volume power of hair according to the use of the composition

After applying the compositions of Example 1 and Comparative Example 1 to hair traces, the volume power of the hair was evaluated by measuring the height of hair traction volume formed by use of the composition.

The hair strain used in this test was about 2 g in weight and about 11 cm in length and was purchased from Phoenix Korea Co., Ltd. (Duck-ri, Bongdam-eup, Gyeonggi province, Korea) and used 20 hair traces for each composition The results were compared. Hair traces were carried on a 10% aqueous solution of each shampoo composition for 20 minutes. After the impregnation, the traces were rinsed for 30 seconds and completely dried with a blow dryer. After the traces were completely dried, they were allowed to stand in a constant temperature and humidity chamber (temperature: 30 ° C, humidity: 40% RH) for 24 hours. After that, the hair traces were erected perpendicular to the surface of the ground, and the traces were tilted naturally. The height from the horizontal of the point moved 1 cm to the right from the center point of the traces was measured. The measurement results are shown in Table 2 below.

N (number of trusses) Volume height average (mm) Standard Deviation Example 1 20 58.95 10.17 Comparative Example 1 20 31.15 11.2 Comparative Example 2 20 41.09 10.1 Comparative Example 3 20 51.88 11.82 Comparative Example 4 20 59.21 11.54 Comparative Example 5 20 60.54 10.99

From the results shown in the above Table 2, it can be seen that the conventional shampoo composition of Comparative Example 1 can provide softness to the hair, but the volume-forming effect is small. On the other hand, it can be seen that the volume height average of the hair traces treated according to the first embodiment of the present invention is significantly different from the value of Comparative Example 1 (p <0.05, paired T-test).

From the above results, it can be seen from the above results that the improvement in the volume power in hair traces can be achieved by using polyquaternium-11 alone, purified water * vapia * methacrylamide * vinyl imidazolecopolymer * ethanol alone or polyquaternium-11 and purified water * Vinylimidazol polymer * ethanol alone, or polyquaternium-11 alone, purified water * vipi * methacrylamide * vinylimidazol polymer * ethanol alone, or polyquaternium- -11 and purified water * Vipi * methacrylamide * vinyl imidazol polymer * ethanol was used in order to determine the degree of improvement of the volume power.

[Test Example 2] Evaluation of hair volume by polyquaternium-11 and vinyl imidazole copolymer

In the same manner as in Test Example 1, the volume power of hair by use of the composition of Example 1 and Comparative Examples 2 to 5 was evaluated. In this test example, ten hair traces were used for each composition. In addition, the evaluation experiments were conducted using two sets, one set using each of the compositions of Example 1, Comparative Example 2 and Comparative Example 3, and one set using the compositions of Example 1, Comparative Examples 4 and 5 , And the hair tress used in the evaluation of the composition of Example 1 in each set used a separate tress

The evaluation results for the two sets are shown in Tables 3 and 4, respectively.

N (number of trusses) Volume height average (mm) Standard Deviation Example 1 10 18.3 3.09 Comparative Example 2 10 11.9 3.12 Comparative Example 3 10 10.1 3.98

(p < 0.05, paired T-test).

N (number of trusses) Volume height average (mm) Standard Deviation Example 1 10 14 3.37 Comparative Example 4 ^* 10 12.7 4.16 Comparative Example 5 ^** 10 11.1 3.37

*: p > 0.05, p = 0.523, paired T-test

**: p> 0.05, p = 0.066, paired T-test

From the results of the above Table 3, the volume height average value of the hair traces treated in Example 1 according to the present invention are the values of Comparative Examples 2 to 5 using polyquaternium-11 or vinylimidazole copolymer alone It can be seen that there is a significant difference.

[Test Example 3] Bubble strength evaluation

The foaming powers of the compositions of Example 1, Comparative Examples 2 and 3 were compared. One liter of an aqueous solution in which each of the above shampoo compositions was diluted to a 10% content ratio (by weight) was prepared. This was measured using a SITA form tester R-2000 (SITA Messtechnik GmbH, Germany). The principle of measuring the bubble in a device is to mechanically operate the diluted liquid to form bubbles and measure the volume of the bubbles formed. 250 ml of the above aqueous solution was taken into the apparatus and the solution was vigorously stirred at a rate of 800 R / min to form bubbles. The stirring was performed ten times, and the result of the formed foam volume was recorded. This was repeated 20 times in total. The measurement results are shown in Table 5 (unit: ml)).

Air bubble height Stirring time Example 1 Comparative Example 2 Comparative Example 3 10 698.3333 726.6667 677.6667

Table 5 shows that the bubble power was the best in the case of Comparative Example 2 after 10 times of stirring, but the bubble power was similar in Example 1, Comparative Examples 2 and 3.

Generally, the acrylate-based polymer that is prescribed for the hair volume effect is a component that forms a coating layer on the hair and remains on the surface of the hair to impart the function. Therefore, the bubble and cleaning power of the surfactant It acts in opposition to the removal of the sebum / soil component, thus reducing the foaming power. Therefore, by using an acrylate-based polymer in order to maximize the volume effect of hair, the foaming power is reduced, which is undesirable from the viewpoint of function inherent in shampoo.

However, as can be seen from Table 5 above, the composition of Example 1 according to the present invention was not particularly reduced in foaming power. This indicates that the composition of Example 1 according to the present invention has improved bubble power and maintains a constant foaming power and does not decrease the cleansing power, as confirmed in the test.

[Test Example 4] Sensory evaluation

The compositions of Example 1, Comparative Examples 2 and 3 were subjected to sensory evaluation as follows. 10 professional evaluation personnel were allowed to use the compositions of Example 1, Comparative Examples 2 and 3, respectively, and then subjected to a comparative test on the evaluation items shown in Table 6 below. The lowest score was set to 1 and the highest The test was conducted with a score of 5. The residual amount of hair refers to the degree of residual foreign matter felt in the hair after washing and thorough drying of the hair using the composition, and shows a change in feeling depending on the inclusion of additional components in the composition. The test results are shown in Table 6 below.

Item Hair softness / smoothness Hair residue Example 1 4 4 Comparative Example 2 4 3 Comparative Example 3 3 4 Comparative Example 4 3 5 Comparative Example 5 3 6

From the results of Table 6, it can be seen that the composition of Example 1 according to the present invention has a high bubble-forming degree and a large amount of bubbles as shown in Test Example 3, so that it has excellent washing power and smooth hair. In comparison with Comparative Example 2 and Comparative Example 3 in which polyquaternium-11, which is a component for improving the hair volume, and only one of vinylimidazole copolymer components, in Example 1 according to the present invention, hair As a result, there was no decrease in feeling and sensory level due to the combination of polyquaternium-11 and vinylimidazole copolymer components.

On the other hand, in the case of Comparative Examples 4 and 5 including a large amount of polyquaternium-11 and one of the vinyl imidazole copolymer components, the effect of softening the hair was not so great, and the degree of the residual foreign matter was large, It can be confirmed that the feeling of freshness is greatly deteriorated.
