Description

Sulfate-Free Shampoo Composition Containing High Concentration of Sulfosuccinate Surfactant ", which contains a high content of sulfosuccinate type surfactant,

The present invention relates to a cosmetic composition for scalp and / or hair, and more particularly to a cosmetic composition for scalp and / or hair which does not contain a sulfate surfactant and has improved skin irritation and hair friction.

In general, shampoos used to clean and keep hair and scalp clean and beautiful can be used in addition to cleaning purpose such as ease of combing, softness, smoothness, luster, reduction of friction on the surface of hair, prevention of static electricity, It is used for the purpose.

Conventional cosmetic compositions for scalp and / or hair use anionic surfactants basically for excellent foamability and detergency, and additionally use nonionic surfactants for solubilizing and emulsifying and dispersing functions.

As the surfactant, a sulfate surfactant is generally used. For example, a surfactant such as ammonium laureth sulfate may be used as disclosed in Korean Patent Laid-Open No. 10-2009-0056321, Sodium laureth sulfate is used as disclosed in Patent No. 10-0845393.

However, the sulfate surfactant has a strong stimulus to accelerate the damage of the hair, and it has a problem of accelerating the water drop (color dropout) of especially dyed hair (dyed hair) due to excessive washing power, and a study on the sulfate- (See, for example, Korean Patent Publication No. 10-2013-0055386, Korean Patent Publication No. 10-2013-0055387, JOURNAL OF COSMETIC SCIENCE, 54, 559-569 (November / December 2003), etc.).

Although a variety of sulfate-free compositions have been studied in this way, there are many cases in which there is substantially no difference in stimulation between a composition containing a sulfate-type surfactant and a sulfate-based surfactant, And the hair conditioning effect is deteriorated.

2. Experimental Example 1: skin irritation test ( HET -CAM Test)

In order to test the skin irritation of the shampoo composition according to the present invention, the inventors of the present invention used Comparative Experiments 1, 2 and 3 in which an anionic surfactant was used at the same 40% by weight using a HET-CAM Test (Hen's Egg Chorioallantoic Membrane) Comparative Example 2, Example 3 and Example 4 were diluted to a concentration of 10% and evaluated by the following method.

This test is performed by applying a test substance to the chorioallantoic membrane (CAM) of a fertilized egg, representing the degree of blood vessel response of the conjunctiva of the eye caused by the substance. Generally, , white horn) are used for this test.

The modified white eggs were prepared and incubated for 10 days in the incubator. After removing egg shells in the air sacs and removing the villus membranes, the vascular response time was measured by applying test materials.

As a result, as shown in Fig. 1, it was confirmed that blood vessel hemolysis and hemorrhage occurred in a strong stimulation reaction in Comparative Example 1 which is a sulfate surfactant. In Comparative Example 2 using a sulfate-based surfactant, Stimulation reaction and hemolytic hemolysis and hemorrhage occurred. However, in Examples 3 and 4 containing 40 wt% of sulfosuccinate and 60 wt% of sulfosuccinate, it was confirmed that there was no irritation reaction and no hemolysis.

Therefore, the shampoo composition according to the present invention containing sulfosuccinate was found to be extremely hypolipidic in vivo.

As a result, as shown in Table 2, it was confirmed that when the sulfosuccinate type surfactant was used in an amount of 40 wt%, the ratio of the increased amount of bubbles increased by 30 wt% and 35 wt% It was confirmed that bubble power was superior to those of Comparative Examples 1 and 2 using the sulfate and sulfonate surfactants. When the cationic water-soluble polymer was included in Comparative Example 3 in which the cationic water-soluble polymer was not included, As shown in FIG. In addition, it was confirmed that the best result was obtained in the fourth embodiment.

4. Experimental Example 3: Evaluation of transparency of formulation

The present inventors conducted experiments to confirm the transparency of the shampoo composition prepared in the composition of Table 1 above. In order to quantify the transparency, the transparency was measured using a UV-Vis spectrophotometer and is shown in Table 3 below. The compositions of the formulation were each measured by refluxing with purified water. The closer to 0, the higher the transmittance and the higher the solubilization power was.

Comparative Example 1 Comparative Example 2 Comparative Example 3 Example 1 Example 2 Example 3 Example 4 transparency 0.177 0.101 0.010 0.093 0.071 0.008 0.004

5. Experimental Example 4: Friction test of hair

The present inventors have evaluated the conditioning effect of the softness of the hair. The shampoo composition as shown in Table 1 was shampooed in 0.5 g of each of the hair tresses, and then completely dried. Then, the hair was heated at a constant temperature The samples were stored in a humidity chamber (25 ° C, 80%) for 8 hours and then repeated three times. At this time, the smaller the friction, the smaller the value and the softer the hair.

As a result, as shown in Fig. 2, it was confirmed that the hair friction of Examples 3 and 4 containing 40 wt% and 60 wt% of the sulfosuccinate type surfactant was the least and the softest was the least.
