Description

Transparent composition for hair

The content of the present invention relates to a transparent composition for hair, which contains polyquaternium-73 (Polyquaternium-73, PQ-73).

Hair cleanser (shampoo) removes pollutants and sebum on the scalp and hair, and makes the hair clean. However, the process of using shampoo removes the moisturizing ingredients of the hair along with the removal of sebum, thus reducing the softness of the hair and increasing the dryness of the hair, thereby making the hair knotted and difficult to handle. In order to solve these problems, in the commonly used opaque shampoo, a conditioner is added to increase the softness of the hair. However, the use of traditional hair conditioners in transparent shampoos is limited by the formulation becoming opaque.

Transparent shampoos with a clean and pure image tend to be used as shampoos for babies and children, and provide aesthetic advantages by virtue of their beautiful appearance. However, when traditional hair conditioners are used, the formulation becomes opaque and the care ingredients added to it are limited. Therefore, there is a problem that the product quality is unsatisfactory and the amount of foaming is insufficient, resulting in insufficient function as a shampoo. Adult hair can be severely damaged by pollution, frequent perms, blow-drying, dyeing and combing. Therefore, hair cleansers need to have at least a certain level of care effect. However, in the case of transparent shampoo, this limitation in the formulation does not meet the level required by consumers.

According to the related art, the cationic polymer that is often used in transparent shampoos is PQ-10, which has limitations in imparting softness and gloss to hair due to the above-mentioned problems.

Therefore, it is necessary to study a transparent shampoo composition that can maintain its transparency to maintain a clean and beautiful appearance, will not reduce the cleansing power of the proper function as a shampoo, can generate a large amount of foam, and show excellent care The effect does not accumulate.

Without departing from the spirit and scope defined by the appended claims of the content of the present invention, those skilled in the art will be able to understand the modifications, substitutions and insertions made to the embodiments and test embodiments.

Examples 1-4 and Comparative Examples

According to Examples 1-4 and Comparative Examples, the shampoo compositions were prepared as shown in Table 1 below. The commercially available products used are PQ-73 (Mitsubishi Chemical Corporation, Diasleek C-802), PQ-10 (KCI, POLYQUAT 3000KC), sodium laureth sulfate (Miwon, MICOLIN ES628), and coconut oil Propyl betaine (Miwon, MITAINE CA) and sodium lauryl sarcosinate (Miwon, Miami L-30). It can be seen from the photo in Figure 1 that the formulations described in Examples 1-4 are transparent formulations. [Table 1]

[Test Example 1] Comparison of hair softness

(Test Example 1-1) Hair softness test during rinsing

In order to determine the composition for the hair softness test in the rinsing process described in the summary of the present invention, the hair was immersed in each 10% diluent of Comparative Example and Examples 1-4, and fixed on the combing machine. Then, give water through the shower and measure the force required to comb the hair when it is rinsed. The results are listed in Table 2 below. The combing test is a general test method in this field. The greater the force required for combing the hair, the lower the effect of care. [Table 2]

After the test, compared with the comparative example using PQ-10, Examples 1-4 using PQ-73 showed that the hair required less combing force during rinsing. Therefore, it is demonstrated that Examples 1-4 provide higher hair softness during hair rinsing. Specifically, Example 4 shows that the softness of the hair is highest during rinsing.

(Test Example 1-2) Combing test of dry hair

In order to determine the composition for the softness of the hair during drying according to the present invention, the hair tresses were cleaned with each 10% dilution of the comparative example and the examples 1-4 and allowed to dry completely for one day. The carding machine was used to measure the force required for carding, and the results are listed in Table 3 below. [table 3]

After the test, compared with the comparative example using PQ-10, Examples 1-4 using PQ-73 showed that the hair required less combing force during combing. Therefore, it is proved that Examples 1-4 provide higher hair softness to dry hair. Specifically, Example 4 showed the highest softness on dry hair.

[Test Example 2] Comparison of hair gloss

In order to compare the glossiness of the hair using the composition of the present invention, a normal hair bundle and a dyed hair bundle were prepared separately. The compositions of Comparative Example and Example 4 were repeated five times each for each bundle of hair. Place each hair tress in a constant temperature room (30°C, relative humidity 40%) for one day to completely dry it. The dried hair is shown in Figure 2. After fixing the hair on the gloss meter, the gloss of the hair was measured. The gloss values obtained are listed in Table 4 below. [Table 4]

After the test, compared with the test example, the treatment of Example 4 provided higher gloss in both normal hair and dyed hair. As shown in Figure 2, the dyed hair and normal hair treated with Example 4 showed low light scattering and high hair visibility. Therefore, it is shown that the composition described in the summary of the present invention enhances the gloss of hair.

[Test Example 3]

Ask seven groups of shampoo experts to compare Examples and Examples 1-4 according to usual usage, and give each item a score from 1 to 10 (1: worst, 5: satisfactory, 10: excellent). Average the obtained seven component numbers and calculate the result. The results of each item are shown in Table 5 below and Figure 3 below. [table 5]

It can be seen from the results of the panel test that 1) compared with the comparative example, the examples 1-4 provide a higher amount of foam, 2) compared with the comparative example, the examples 1-4 are washing During the period, in the wet state, and after drying, there is better softness, and 3) Compared with the comparative examples, Examples 1-4 provide higher hair gloss. Specifically, Example 4 provided the highest result among all evaluation items.
