Description

Transparent composition for hair {A transparent composition for hair}

The present specification relates to a transparent formulation composition for hair comprising polyquaternium-73 (PQ-73).

Shampoo, a hair cleanser, makes hair clean by removing contaminants and sebum from the hair and scalp, but through the shampooing process, the sebum and moisturizing ingredients of the hair are removed, weakening the softness of the hair and drying it, making the hair tangled and difficult to handle. To compensate for this, in the case of a general opaque shampoo, a hair conditioning agent is included to increase the flexibility of the hair, but in the case of a transparent shampoo, there is a limitation in that the formulation becomes opaque when a conventional hair conditioning agent is used.

Transparent shampoo is preferred as a shampoo for infants or children with a clean and gentle image, and provides aesthetic advantages with a beautiful appearance. The problem is that it lacks the function as a shampoo because it is dry and the amount of bubbles is insufficient. Adult hair is severely damaged by contamination, frequent perming, hair drying, dyeing, combing, etc. have.

PQ-10 has been mainly used as a cationic polymer used in a conventional transparent shampoo, and there is a limit in imparting softness and gloss to the hair due to the above problems.

Therefore, research on a transparent shampoo composition that can provide excellent conditioning effect without lowering the cleaning power, which is the original role of shampoo, while maintaining transparency and providing a clean feeling, is rich in air bubbles and does not have build-up. need.

As a result of the experiment, compared to the comparative example using PQ-10, it was confirmed that Examples 1 to 4 using PQ-73 had less force during combing, so that the softness on dry hair was superior. In particular, in the case of Example 4, the softness on dry hair was the best.

[ test example 2] Comparison of hair gloss

When applying the composition of the present invention, in order to compare the gloss in hair, normal hair and dyed hair tresses are prepared. The compositions of Comparative Examples and Example 4 were repeatedly used for each tress 5 times. 30 ℃, 40% relative humidity) was incubated for one day in a constant temperature room to dry completely. The dried hair is shown in FIG. 2 . The hair was fixed to a gloss measuring device and the results of measuring the gloss were shown in Table 4 below as Luster Value.

dyed hair comparative example 12.58 Example 4 14.83 normal hair comparative example 30.69 Example 4 39.56

As a result of the experiment, compared to Comparative Example, Luster Value was excellent in both dyed and normal hair when treated with Example 4, and the dyed and normal hair treated with Example 4 had less light scattering and excellent hair clarity, as shown in FIG. It was confirmed that the gloss of the hair was improved when the composition of the present invention was used.

[ test example 3] Panel test

Seven members of the shampoo panel were asked to use Comparative Examples and Examples 1 to 4 as usual shampoo, and then to give each item a score between 1 and 10. (1 point very bad - 5) Point Average - 10 points Very good) The panel test result was calculated by averaging the scores of 7 people, and the results for each evaluation item are shown in Table 5 and FIG. 3 .

Evaluation items comparative example Example 1 Example 2 Example 3 Example 4 amount of bubbles 4.57 6.86 6.14 5.57 7.29 softness when rinsing 3.71 4.00 7.29 6.86 8.14 softness when wet 4.43 4.71 7.00 6.43 7.86 soft after drying 4.14 4.86 6.57 6.71 8.00 hair shine 4.86 5.29 5.29 6.14 6.86

Looking at the results of the panel test, 1) In terms of the amount of foam, it can be seen that Examples 1 to 4 are superior to those of Comparative Examples, 2) In terms of softness during rinsing, softness in a wet state, and softness after drying, Examples 1 to 4 were superior to Comparative Examples, and 3) it was confirmed that Examples 1 to 4 were superior to Comparative Examples in hair gloss. In particular, Example 4 showed the best in all of the above evaluation items.
