[Test Example 4: Confirmation of formulation change]

To each of these Example 4 and Comparative Example 1 samples, water was mixed at a weight ratio of 1: 9 (sample 1: water 9) and stirred, and the viscosity was measured using a Brookfield viscometer at 25 ° C., respectively. As a result, in Example 4 it was 5,000cps, in Comparative Example 1 it was confirmed that the 2,500cps, the suspension formulation corresponding to the picture shown by the symbol 2 in Figs.

Furthermore, water was mixed with each of the samples of Example 4 and Comparative Example 1 in a weight ratio of 2: 8 (sample 2: water 8), and stirred, and then the viscosity (second viscosity) was measured using a Brookfield viscometer at 25 ° C. Measured. As a result, it was confirmed that in Example 4 was 45,000cps, in Comparative Example 1 was 33,000cps, it can be seen that the cream formulation corresponding to the picture shown in Figs.

[Test Example 5: Checking the exotherm degree]

5 g of the sample of Example 3 was prepared and the exotherm measured by an alcohol thermometer before and after application to the hair soaked with water of about 25 ° C. showed a difference in exotherm of about 7 ° C. to 32 ° C. after application at 25 ° C. before application to the hair. It was confirmed.

The exothermicity shown in the treatment cosmetic composition for hair and scalp according to an embodiment of the present invention is expected to be due to the hydration breaks the hydrogen bond of water and creates an ion-dipole. In other words, when polyols such as propylene glycol and butylene glycol encounter excess water, the dissolution enthalpy exhibits a negative value, which corresponds to the principle of exothermic reaction.

From the above results, when an amphiphilic polymer and a cationic polymer are used and further provided or incorporated in an infiltration structure physically fixed in the graft conjugate, they are not affected by external environmental factors and do not fall off from the hair even when physically stimulated. It can be seen that it can be maintained well.

In addition, in terms of softness, elasticity and smooth hair texture (Softness, Flexibility, Smoothness), each of the conditioning effects were confirmed, and according to the embodiment of the present invention, in the conditioning composition containing various additives including ethanol and cationic surfactant It can be effectively used in various cosmetic formulations by providing a soft, elastic and smooth feeling conditioning effect on damaged hair by excessive degreasing by ethanol.
