Description

Hair cleaning composition for enhancing the fluffy feeling of hair and application thereof

The present invention relates to a rinse-off hair cleaning composition. More specifically, it relates to a composition that contains polyquaternium-11 and vinylimidazole copolymer mixed in a specific ratio, thereby having a general cleaning effect. At the same time, the hair or scalp cleansing composition improves the bulky feeling of the hair, thereby improving the bulky feeling of the washed hair.

Generally, hair is composed of a protein called keratin. Specifically, hair is keratin containing 14 to 18% of cystine among 18 amino acids. These keratins are a type of protein that is very strong under mild conditions such as water or neutral solvents, but are easily damaged by excessive physical and chemical treatments such as heat during combing and blowing, dyeing, and perming. Recently, due to frequent perm, dyeing and other physical, chemical or environmental factors, the hair has been damaged, causing the hair to be rough and lose its luster, thereby reducing the softness and flexibility effect, and increasing the frictional force. Hair trimming becomes difficult, hair breakage or split ends occur, and the hair becomes thinner and loses its elasticity, resulting in loss of vitality and sagging, thereby losing its fluffy feeling.

In order to solve these problems, research on cosmetics for improving the softness of hair during and after washing, and restoring and strengthening damaged hair is continuing. As a result, various methods for imparting powerful and sustained hair conditioning effects have been tried and developed, and they have been put into practical use.

In particular, the conventional function of hair or scalp cleansing compositions represented by shampoos is to clean the hair and scalp. However, recently, in addition to the original cleansing purpose, various products with additional functions have begun to come into the market. In particular, products under development include products that use silicon to prevent hair from flying up after drying and improve softness, and products that aim at finishing and repairing hair damaged by hair treatments such as dyeing or perming.

However, although existing products are beneficial to provide hair with conditioning effects such as softness, moisturization, flexibility, and ease of combing, but for fine hair or hair that is lifeless due to damage, it will cause the hair to collapse and droop excessively. , So there is a problem in imparting a fluffy feel to the hair.

[Reference Example 1] Preparation of shampoo composition

According to the composition of Table 1 below, a shampoo composition was prepared by a conventional preparation method. Example 1 is a composition containing polyquaternium-11 and vinylimidazole copolymer (weight ratio 1:5), and Comparative Example 1 is a composition that has a normal level of cleaning power and rinsing properties, and imparts softness to the hair when dried. Existing shampoo composition. In addition, Comparative Example 2 and Comparative Example 4 are compositions containing polyquaternium-11 alone, and Comparative Examples 3 and 5 are compositions containing vinylimidazole copolymer alone. In addition, the vinylimidazole copolymer uses purified water*VP*methacrylamide*vinylimidazole copolymer*ethanol (product of BASF in Korea).

[Table 1]

[Test Example 1] Evaluation of the bulkiness of hair based on the application of the composition

After applying the composition of Example 1 and Comparative Example 1 to braids, the bulkiness of the hair was evaluated by measuring the height of the volume of the braids formed by the use of the composition.

The braid used in this experiment weighs about 2g and has a length of about 11cm. It was purchased from Korea Phoenix Co., Ltd. (located in Bongdam-eup, Hwaseong, Gyeonggi-do, Korea). Each composition used 20 braids, and the results were compared. The tresses were immersed in a 10% aqueous solution of each shampoo composition for 20 minutes. After dipping, wash the braids in running water for 30 seconds and blow them dry completely with a hair dryer. After confirming that the hair braid is completely dry, let it stand for 24 hours in a constant temperature and humidity room (temperature: 30°C, humidity: 40% relative humidity). After that, stand the tresses perpendicular to the ground surface, so that the tresses are naturally inclined. The height of the position from the center point of the braid moved 1 cm to the right was measured. The measurement results are shown in Table 2 below.

From the results of Table 2 above, it can be confirmed that although the conventional shampoo composition of Comparative Example 1 can provide softness to the hair, the effect of forming a fluffy feeling is small. On the contrary, it can be known that the average volume height of the braids treated in Example 1 of the present invention is significantly different from the value of Comparative Example 1 (p<0.05, paired T-test) ).

However, it cannot be confirmed from the above results that the increase in bulkiness in the braids is due to the use of polyquaternium-11 alone, and the use of purified water*VP*methacrylamide*vinylimidazole copolymer*ethanol alone. It is also formed by the combined use of polyquaternium-11 and purified water*VP*methacrylamide*vinylimidazole copolymer*ethanol. Therefore, in order to understand the use of polyquaternium-11 alone, purified water* Fluffy when VP*methacrylamide*vinylimidazole copolymer*ethanol is used alone or polyquaternium-11 and purified water*VP*methacrylamide*vinylimidazole copolymer*ethanol is used in combination The degree of force improvement was tested as follows.

[Test Example 2] Evaluation of hair bulkiness by mixing polyquaternium-11 and vinylimidazole copolymer

In the same manner as in Test Example 1 described above, the hair bulkiness of the compositions of Example 1 and Comparative Examples 2 to 5 was evaluated. However, in this test example, 10 braids were used for each composition. In addition, two sets were used, namely, one set using the compositions of Example 1, Comparative Example 2, and Comparative Example 3, and the other set using the compositions of Example 1, Comparative Example 4, and Comparative Example 5, respectively. An evaluation experiment was performed for one series, and in each series, other braids were used for the braids used in the composition of Evaluation Example 1.

The evaluation results of the two series are shown in Table 3 and Table 4 below, respectively.

[table 3]

From the results in Table 3 above, it can be known that the average loft height value of the braids treated with Example 1 of the present invention is compared with that of Comparative Example 2 to Comparative Example 5 using polyquaternium-11 or vinylimidazole copolymer alone. Compared with the value, there is a significant difference.

[Test Example 3] Evaluation of Foaming Power

The foaming power of the compositions of Example 1, Comparative Example 2, and Comparative Example 3 were compared. Prepare 1 L of the aqueous solution for diluting each shampoo composition at a content ratio of 10 (by weight). The foaming power was measured using SITA form tester R-2000 (SITA Messtechnik GmbH, located in Germany). The bubble measurement principle of this instrument is to mechanically drive the diluted liquid to form bubbles, and then measure the volume of the bubbles formed. Take out 250 ml of the aqueous solution and add it to the instrument. The solution is stirred vigorously at a speed of 800 R/min to form bubbles, then stirred 10 times, and the result of the volume of the foam formed is recorded. Repeat this step mechanically 20 times. The measurement results are shown in Table 5 (unit: ml).

[table 5]

It can be seen from Table 5 that after 10 times of stirring, the foaming power of Comparative Example 2 was the best, but the foaming power of Examples 1, Comparative Examples 2 and 3 showed similar levels.

Generally, the acrylic polymer used for the hair volume effect is a component that forms a coating layer in the hair. The principle is to remain on the surface of the hair to impart functions. Therefore, it is effective for foaming and cleaning power by surfactants. It has the opposite effect in removing sebum/dirt components attached to the hair. Therefore, the foaming power will decrease. Therefore, when an acrylate polymer is used in order to maximize the bulking effect of hair, the foaming power is reduced, and therefore, it is not good in terms of the original functionality of the shampoo.

However, it can be known from Table 5 above that the foaming power of the composition of Example 1 of the present invention is not particularly reduced. As confirmed in the above test, this result indicates that the composition of Example 1 of the present invention can improve the bulking power of the hair while maintaining the foaming power to a certain extent. Therefore, the cleaning power is not reduced.

[Test Example 4] Sensory Evaluation

The following sensory evaluations were performed on the compositions of Example 1, Comparative Examples 2 and 3. After 10 professional evaluators used the compositions of Example 1, Comparative Example 2 and Comparative Example 3, a comparative test was performed on the evaluation items shown in Table 6 below. The test rule is to set the lowest score Is 1, and the highest score is set to 5. The residual feeling of hair means the degree of residual foreign body feeling felt in the hair after the hair is washed and completely dried using the composition, and it means the change in the feeling of use caused by the additional ingredients contained in the composition. The test results are shown in Table 6 below.

[Table 6]

From the results in Table 6 above, it can be confirmed that the composition of Example 1 of the present invention, as shown in Test Example 3 above, has a rapid bubble generation degree and a large amount of bubbles, so that it has excellent cleaning power and can make hair soft. . In addition, the hair residue feeling when using Example 1 of the present invention and the comparative example 2 and the comparative example containing only one of the polyquaternium-11 and vinylimidazole copolymer components that have a function of enhancing the hair bulkiness Comparison of 3 shows a similar level. Therefore, it can be confirmed that the mixed use of polyquaternium-11 and vinylimidazole copolymer components does not bring about a decrease in the feeling of use and sensory level.

In addition, it can be confirmed that Comparative Examples 4 and 5, which contain a large amount of one of polyquaternium-11 and vinylimidazole copolymer components, have little effect on softening the hair and a large degree of residual foreign body feeling in the hair. As a result, the freshness after washing the hair is greatly reduced.
