Description

[0001] HAIR CLEANSING COMPOSITION [0002]

Disclosed herein is a composition for low stimulus hair cleaning.

In recent years, hair is damaged due to various physical and chemical factors such as frequent combing, perming, dyeing, etc., so that the hair becomes rough and loses its gloss and softness and softening effect are frequently deteriorated. As a result, the hair is hard to be trimmed, the hair is cut off, and the ends are cracked.

To address this problem, there has been a continuing research into detergents or hair conditioning ingredients to improve the softness of the hair during or after cleaning, and to restore damaged hair. In particular, in order to protect hair, prevent damage, and provide a conditioning effect, a shampoo containing an anionic surfactant as a main component for removing contamination of hair and scalp by merely emphasizing only the cleaning function in the prior art, So-called conditioner shampoos, in which a conditioning agent is added in addition to a surfactant, have been developed and put into practical use, and their use is increasing.

However, in the detergents containing anionic surfactants and cationic polymers as constituents, most of the anionic surfactants are highly irritating to the skin, which may be a cause of irritation of the sensitive scalp. Therefore, nonionic surfactants having relatively low irritation are suitable for sensitive scalp cleansing, but they are not widely used because they are difficult to realize air bubbles and conditioning.

Experimental Example 1. Comparison of nonionic surfactants

The foaming power of the nonionic surfactant was measured by the following method.

Specifically, 1 g of the surfactant raw material was taken on the basis of the solid content, and 10 g of water was added to perform 20 hand folding operations. The amount and texture of the formed bubbles were visually evaluated.

FIG. 1 shows a photograph of the result of observation of the bubble strength of the nonionic surfactant. As shown in Table 2 and FIG. 1, the bubble amount and bubble retention time of coco-glucoside and polyglyceryl-10 laurate were the most excellent among the nonionic surfactants. Also, the amount of coco-glucoside in the alkyl glucoside and the bubble retention time were the most excellent.

Experimental Example 2: Comparison of cationic polymers

The composition for hair cleansing according to the present invention has the effect of improving hair conditioning in a nonionic surfactant system by including a cation-substituted cellulose polymer. In this experimental example, the conditioning effect was confirmed for four polymers having similar degree of cation substitution in order to determine the effect of addition of an alkyl group on the composition for hair cleansing in the cation-substituted cellulose polymer.

Four types of polymers used were Polyquaternium-10 (Ucare LR30M, Ucare JR400, Dow chemical) and Polyquaternium-67 (Softcat SL100, Softcat SX400X, Dow chemical) (A), (b), (c) and (d) of Table 4 below were blended with each of the nonionic surfactants, followed by wetting 10 g of water to the hair tress, And then rinsed. At this time, softness at the initial stage of rinsing and softness at the end of rinsing were evaluated from 1 to 10 points by eight expert panelists and shown in Fig.

As a result, as shown in FIG. 2, the sample compositions (c) and (d) including polyquaternium-67 showed a characteristic that the softness continued to the end of rinsing. In particular, the high molecular weight polyquaternium-67 showed improved softness at the end of the rinse than at the initial softness of the rinse. Thus, it has been found that the addition of an alkyl group to the cation-substituted cellulose polymer has the effect of improving hair conditioning in the nonionic surfactant system.

In a general shampoo, a complex of cation polymer-anionic surfactant (coacervate) is precipitated by insoluble precipitation by dilution. When only a nonionic surfactant is used without using an anionic surfactant, conventional coacervate is not precipitated. However, when the transparent sample compositions (a) and (c) were each diluted 100 times, precipitation was also observed in the sample composition of (C) as shown in Fig. It is judged that the polymer complex is precipitated through hydrophobic bonding between the alkyl substituents in the polyquaternium-67 molecule or between the alkyl substituent and the polymer chain, and the increase in adsorption of the polymer results in the sample composition of (c) At the end, softness seems to be the result of an increase.

Experimental Example 3. Comparison of Shampoo Composition

For the shampoo compositions of Examples 1 and 2 and Comparative Examples 1 and 2, the quality attributes of bubble power, conditioning feeling upon rinsing, feeling of conditioning after drying, and residual feeling were rated on a scale of 1 to 10, Were compared and compared. Comparative Example 2 shows a third-party product (Johnson's Baby Shampoo, manufacturer Johnson & Johnson) containing a high content of non-ionic surfactants with similar stimulation levels to Examples 1 and 2.

Fig. 4 shows the result of observation of quality properties of the shampoo composition. As a result, Example 1 showed a better conditioning effect than a conventional shampoo using an anionic surfactant (Comparative Example 1). Compared with Example 2 or Comparative Example 2, the composition exhibited excellent foamability and improved conditioning effect even when a nonionic surfactant was used. In particular, the composition of Comparative Example 2 containing a nonionic surfactant having a low level of conventional stimulation The hair cleansing composition according to the present invention was found to provide excellent foamability and conditioning effect in a nonionic surfactant system.

Experimental Example 4: Low Stimulation Test

The compositions of Example 1 and Comparative Examples 1 and 2 were evaluated for irritation.

The stimulation was evaluated by a 5% dilution with physiological saline followed by a HET-CAM test. The mucosal irritation test method is disclosed in Korean Patent Laid-Open Publication No. 10-2014-0115140 (a composition for scalp and / or hair containing disodium R-sugar-sulfosuccinate) and the ocular mucosal stimulation test method described in Reference Example 1 Which is hereby incorporated by reference in its entirety. As a result, the composition for hair cleansing according to the present invention showed no irritation unlike the conventional shampoo composition containing an anionic surfactant, and thus it was confirmed that the composition had excellent stability of use.
