Description

Composition for washing hypoallergenic hair or scalp {Composition for washing hair or scalp with low irritant}

The present invention relates to a composition for cleaning hair or scalp, which is hypoallergenic and has a soothing effect on scalp, and more specifically, contains a combination of an anionic surfactant and an amphoteric surfactant, and has a foam-type formulation, thereby reducing irritation. In addition, the present invention relates to a detergent composition for hair or scalp, which specifically exhibits an anti-inflammatory effect by containing a plant-derived extract, and thus a scalp soothing effect, specifically a shampoo composition.

In general, the shampoo composition, since the ability to clean the hair is the most important function, includes a surfactant as a main component. As the surfactant, anionic surfactants are basically used for cleaning power and foaming power, and in addition, nonionic surfactants for solubilization and emulsifying and dispersing functions are further used.

At this time, as anionic surfactants, sulfate-based surfactants such as alkyl sulfates, alkyl ether sulfates, ammonium lauryl sulfate, ammonium laureth sulfate, and sodium lauryl sulfate have better cleaning power and bubble power than other anionic surfactants. Therefore, it has been widely used in shampoo compositions.

However, while the sulfate-based surfactant has excellent cleaning power, there is a problem that the irritation to the skin and eyes is large and the irritation is strong to promote hair damage. In addition, anionic surfactants such as fatty acid salts have excellent cleaning power, but have a drawback of providing a pulling phenomenon on the skin after cleaning by a high pH.

The stimulation caused by these surfactants is not very stimulating for people with normal skin, but it is felt as a great stimulus for people with skin diseases such as atopy or acne, sensitive skin, etc., and the use is limited.

For this reason, attempts have been made to make a detergent using only a small amount of anionic surfactant, or to make a detergent using only a relatively non-irritating nonionic surfactant. However, a detergent using a small amount of anionic surfactant has a large cleaning power. The cleaning agent using only a nonionic surfactant has a disadvantage in that its foaming ability is greatly reduced and its performance as a shampoo is very low.

Therefore, there is still a need for a shampoo composition that has good skin power and low skin irritation while maintaining cleaning power.

[Test Example 1] Sensory evaluation

For the shampoo compositions of Comparative Examples 1 to 12 and Examples 1 to 3, sensory evaluation was performed as follows. After 10 professional evaluation personnel were used to use the shampoo compositions of Comparative Examples 1 to 12 and Examples 1 to 3, respectively, a comparative test was performed on the evaluation items shown in Table 3 below, and the lowest score was 1 The test was conducted with the highest score of 6. The evaluation results are shown in Table 3 below.

Comparative example Example One 2 3 4 5 6 7 8 9 10 11 12 One 2 3 Bubble 5 5 2 3 6 5 5 5 5 5 5 5 6 4 5 Bubble generation rate 4 4 2 3 6 5 4 5 5 5 4 4 5 5 5 Wet hair softness 3 One 2 3 One 3 3 2 4 2 4 4 6 6 4 Dry hair softness 5 3 2 2 2 5 2 4 4 2 3 3 6 6 4 Cleaning power 6 5 2 2 6 4 4 4 4 4 5 5 5 5 5 Hair moisturizing 5 4 3 2 3 4 3 3 4 3 2 3 5 5 5 Sum 28 22 13 15 24 26 21 23 26 21 23 24 33 31 28

As shown in Table 3, when the content of disodium laureth sulfosuccinate is outside the appropriate range (Comparative Examples 3 and 4), it was found that the amount of bubbles and the rate of bubble formation were low. In addition, when the lauryl hydroxyl facility contained less than the appropriate amount (Comparative Example 5), it was found that there was little hair softness, especially wet hair softness, and even more contained than the appropriate amount, the hair softness was more It was not improved but rather decreased (Comparative Example 6). In addition, when a sulfate-based anionic surfactant was blended instead of disodium laureth sulfosuccinate, the foaming power was improved, but hair softness in wet and dry conditions was reduced and hair moisturization was also decreased (Comparative Example 7 And 8). In addition, if the glutamate-based anionic surfactant disodium cocoyl glutamate is not included, the overall feeling of use is not significantly reduced, but it can be confirmed that the degree of deterioration in terms of hair softness, cleansing power, and hair moisturizing is lower than when it is included (( Comparative Example 9), when an appropriate amount of disodium cocoyl glutamate was formulated, it was found that the hair softness, the cleaning power and the hair moisturizing feeling were excellent (Examples 1 and 3). However, when the amount of disodium cocoyl glutamate is added in an amount exceeding a certain level, the degree of hair softness is rather reduced (Example 3). In addition, polyquaternium-7 is a cationic polymer, and is particularly suitable when compounded in an appropriate amount. It contributed to the improvement of the softness of the hair in the wet state, and it was shown that the softness level was improved when rinsing compared to the case where it was not formulated (Comparative Example 2).

In the case of Comparative Examples 1 and 10, the surfactant contained in the composition of the present invention was not included at all, and as an anionic surfactant, ammonium laureth sulfate, which is a sulfate-based surfactant, was excellent, so that foaming ability and cleaning power were excellent and amphoteric. Although the hair conditioning effect can be obtained by including cocamidopropyl betaine as a surfactant, there is a disadvantage that it can irritate the scalp when used by the inclusion of a sulfate-based surfactant. In addition, in Comparative Example 10 including guarhydroxypropyl trimonium chloride instead of polyquaternium-7, it was confirmed that hair softness and hair moisturizing feeling were significantly reduced.

In addition, it was found that when the kale extract or coconut oil was not included, dry hair softness and hair moisturization were significantly reduced (Comparative Examples 11 and 12).

[Test Example 2] Evaluation of irritation

The shampoo compositions of Comparative Examples 1 to 12 and Examples 1 to 3 were evaluated for use in terms of irritation by 10 professional evaluation personnel. The compositions of Comparative Examples 1 to 12 and Examples 1 to 3 were used for 3 days by a professional evaluation agent, and then a comparison test was performed on the items shown in Table 4, with the lowest score being 1 and the highest score. The test was carried out with 6. When the sum (D) of each stimulation level was 3 to 8, it was evaluated as hypoallergenic, 9 to 12 medium stimulation, and 13 to 18 strong stimulation. The evaluation results are shown in Table 4 below.

Comparative example Example One 2 3 4 5 6 7 8 9 10 11 12 One 2 3 Itchy scalp (A) One One One One 2 2 3 3 2 3 One 2 One One One Scalp stickiness (B) One 2 3 3 3 3 3 4 2 3 3 2 One 3 3 Scalp itching (C) 2 One One One One 2 3 3 2 4 3 3 One 2 3 Stimulus level sum (D) = A + B + C 4 4 5 5 6 7 9 10 6 10 7 7 3 6 7

As shown in Table 4, in Comparative Example 10, which contains a sulfate-based surfactant and contains guarhydroxypropyl trimonium chloride instead of polyquaternium-7, a significant degree of irritation such as itching, burning, and tingling occurs. It appeared to be. However, in the case of Comparative Example 1 containing a sulfate-based surfactant, cocamidopropyl betaine is used as an auxiliary surfactant, and a small amount of polyquaternium-7 is used, resulting in a small amount of coacervate that may be a stimulus, resulting in a low stimulation level. In addition, the disodium laureth sulfosuccinate used as the main surfactant may have an increased stimulation in combination with lauryl hydroxysulfate or disodium cocoyl glutamate, respectively. And 6, Comparative Example 9.

In addition, it can be confirmed that the irritation level is increased even if it does not contain any of the plant-derived extract kale extract and coconut oil (Comparative Examples 11 and 12).

On the other hand, it can be seen that the examples prepared according to the present invention, in particular Example 1, had a remarkably excellent feeling of use and a low stimulation level.
