Description

Composition for hair comprising 7-dehydrocholesterol

The present invention relates to a composition for hair containing 7-dihydrocholesterol.

Hair damage is caused by a combination of frequent chemicals such as perming and dyeing, physical factors such as extreme hair and hair brushing, and environmental factors such as sunlight and heat.

The process by which these factors cause hair damage is as follows. First of all, the cuticle on the surface of the hair breaks away and the number of cuticle layers decreases, and the inside of the hair is exposed and the hair protein is leaked and denatured. After that, the interstitial material of the hair escapes, and the binding between the cells is loosened, turning into crumbly, glossy, rough hair. When the damage accumulates, the hair is easily cut or broken.

Hair cosmetics are intended to provide proper nutrition to the hair to prevent such hair damage, or to restore the already damaged hair to healthy hair.

For this purpose, the cosmetics for hair should specifically improve the glossiness of the hair, smooth the hair to facilitate combing, and exhibit a hair conditioning action.

7-dihydrocholesterol (7-dihydrocholesterol, 7-DHC) is a new material in the field of cosmetics, which is in the spotlight for skin wrinkle improvement or sun protection.

The present inventors completed the present invention by confirming that when 7-dihydrocholesterol was applied to the hair, the hair improvement effect was exhibited by a completely different mechanism from the cosmetics for skin.

First, purified water, guarhydroxypropyl trimonium chloride, propylene glycol, cetrimonium chloride, and methyl paraben were weighed and dispersed in a Disper Mixer, and then dissolved by heating to 80 ° C (mixture A). Nitchloride, glyceryl stearet, cetearyl alcohol, propyl paraben, cyclomethicone and mineral oil were weighed and dissolved by heating to 80 ° C (mixture B). When the temperature of each mixture reached 80 ° C., the mixture B was slowly added to the mixture A while emulsifying while maintaining the rpm of the ultra homo mixer at 1700 and the paddle mixer at 25 rpm.

After emulsification, cyclopentasiloxane / dimethicone, dimethicone, and 7-dihydrocholesterol complex were added thereto, and the mixture was uniformly mixed with an ultra homo mixer's rpm of 1200 and a paddle mixer of 25. After 2 minutes, cooling was started, and when it reached 65 ° C., Yellow 2002-1, Dimethicone / Isolaures-6 was added thereto, and the mixture was stirred for 1 minute at rpm 2000 in an ultra homo mixer.

When the stirring is 55 ℃ rosemary extract, chamomile extract, lavender extract, sage extract, lily extract, pansy extract, ivy extract, potulaca oleracea extract, keratin amino acid, pyrotonolamine, ethanol, flavoring The rpm of the ultra homo mixer was 1100 and the rpm of the paddle mixer was 25, and it stirred for 1 minute.

Cooling was complete | finished when the temperature of the last stirring material fell to 40 degreeC, and the hair composition of this invention was manufactured.

[Experimental Example] Hair improvement effect by the composition for hair of the present invention

In order to confirm the hair improvement effect by the composition for hair of the present invention, the clinical experiment was performed as follows.

 The test subjects were selected as those whose hair condition was damaged during visual evaluation, hair crumbly, or hair was inflexible, and they were classified into four groups according to the hair condition.

 division                              Hair condition First group  10 men in their 20s to 50s who are stiff, sloppy, and less flexible 2nd group  5 males and 11 females in their 20s to 50s who are stiff, fluffy and flexible Third group  5 men and 15 women in their 20s to 50s who are stiff, sloppy, and less flexible Fourth group  Healthy men 15 to 50 men and 20 women in their 50s

In each group, the composition of Examples 1 to 3 and Comparative Examples 1 to 3 were applied to the head, and after 20 minutes, they were washed in running water using commercially available shampoo.

After allowing the compositions to be used for 30 days in the same manner, the condition of the hair was evaluated.

The hair improvement effect was evaluated in three categories: improvement of hair gloss, lubricity of hair, and hair conditioning action.

The degree of gloss improvement of hair was evaluated by observing the gloss and coating state of each hair using a microscope analyzer (MicroScope Analyizer).

The lubricity of the hair was evaluated by the degree of combing by combing each hair.

The hair conditioning effect was evaluated by the touch when the hair was touched by hand and the degree of static electricity generated when combing.

The evaluation score was set to very good: 3, good: 2, normal: 1, poor: 0 for each item, and the evaluation results are shown in Table 4.

Evaluation item Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Hair gloss 3 2 2 One One 0 Lubricity of hair 2 2 2 One One One Hair conditioning action 3 3 2 One One 0

As shown in Table 4, the hair composition of the present invention was found to be much better than the comparative example in all of the glossiness of the hair, the lubricity of the hair, and the hair conditioning action.

This effect is 7-dihydrocholesterol contained in the hair composition of the present invention is adsorbed to the cuticle layer of the hair to form a hair oil / moisture balance to maintain the damaged hair healthy, and help the penetration of the base and hair protector It seems to be due.

Therefore, the hair composition of the present invention can be seen that the effect of improving the hair is excellent.

The composition for hair of the present invention improves luster of hair and lubricity of hair, and is excellent in hair conditioning action.

Therefore, the hair composition of the present invention can be usefully used as a cosmetic and hair dye for improving hair.
