Description

TECHNICAL FIELD The present invention relates to a multi-component cosmetic and a cosmetic method using the multi-component cosmetic.

Cosmetics are selected according to the needs and preferences of each consumer, and various types are provided according to their uses and purposes. As examples of cosmetics, there are known single-agent cosmetics and multi-agent cosmetics containing a plurality of constituents.

Multi-agent type cosmetics are sometimes used for the purpose of improving desired effects and maintaining the effects as compared with single-agent type cosmetics by using a plurality of components. In addition, since multi-agent cosmetics use multiple constituents, the treatment time is longer than that of single-agent cosmetics, and it tends to be troublesome. It has the advantage of increasing the satisfaction of the resulting treatment.

To give an example of a multi-agent cosmetic, for example, Japanese Patent Laid-Open No. 2008-137995 (Patent Document 1) discloses that predetermined amounts of a quaternary ammonium salt-type cationic surfactant, an amino-modified silicone, a dialkyl ether, and water and a hair cosmetic containing a prescribed amount of acids, a polyhydric alcohol and water, a hair cosmetic capable of imparting excellent smoothness uniformly from the root to the tip of the hair. Techniques have been proposed to provide Further, Japanese Patent Application Laid-Open No. 2002-363055 (Patent Document 2) describes two types of compositions, one containing a predetermined amount of alginic acid and/or a water-soluble salt thereof and the other containing a calcium salt. Techniques have been proposed for providing an aesthetic pack cosmetic excellent in usability and feeling in use by means of an agent-mixed pack cosmetic.

In Comparative Examples 1 to 8, since formation of complexes was not observed (formation of complexes: evaluation x), "uniformity of agent after mixing" was not evaluated.
Separately from the above procedure, 0.5 g of each A agent and each B agent in Examples 1 to 6 and Comparative Examples 1 to 8 were prepared. Subsequently, the A and B agents of Example 1 were transferred to a new vinyl wrap, and the A and B agents of Example 1 were mixed five times by drawing a circle with the index finger on a flat surface. The tackiness of the agent after mixing was sensory evaluated according to the following evaluation criteria. In addition, each A agent and each B agent of Examples 2 to 6 and Comparative Examples 1 to 8 were mixed in the same procedure as the A agent and B agent of Example 1, and the "stickiness of the agent after mixing" was measured. evaluated.

(Evaluation criteria)
Each evaluation criterion is shown below.

Evaluation criteria for "formation of complex" 〇: A complex is generated in the agent after mixing (From the viscosity felt when touching agent A and agent B before mixing with a finger, agent A and agent B When you touch the mixed agent with your finger, you feel the viscosity is high).
×: No complex is formed in the agent after mixing (From the viscosity felt when touching the A agent and the B agent before mixing with a finger, the agent mixed with the A agent and the B agent was touched with a finger Viscosity felt at the time feels the same or lower).

Evaluation Criteria for “Homogeneity of Agent After Mixing” ◯: When the agent after mixing is mixed two or three times in a circular motion with a finger, the viscosity felt by fingers is uniform throughout the agent.
x: When the agent after mixing was mixed with a finger in a circular motion two or three times, the whole agent was uneven, with high and low viscosity areas mixed with fingers.

Evaluation criteria for "adhesiveness" ○: Excellent adhesiveness (A and B agents before mixing are taken on the index finger of one hand, and the agent A The stringiness is stronger when the agent mixed with agent B is stretched with the index finger and thumb).
×: Inferior adhesiveness (agents A and B before mixing are each taken on the index finger of one hand, and the agent mixed with agent A and B The string pull is the same or weak when extended with the index finger and thumb).

(Viscosity measurement)
Apart from the above sensory evaluation, each A agent and each B agent in the multi-agent cosmetics of Examples 1 to 6 and Comparative Examples 1 to 8, and the above "formation of complex" and "formation of agent after mixing The viscosities of each of the A agents and the B agents of Examples 1 to 6 and Comparative Examples 1 to 8 obtained by the uniformity evaluation procedure were measured after mixing.
Viscosity was measured using a stress-controlled rheometer ("Rheo Stress 6000" manufactured by HAAKE) at a measurement temperature of 25°C, a cone-plate sensor diameter of 35 mm, and a cone-plate sensor tilt angle of 2°. Mode, stress: G' was measured from 0.1 Pa to 3000 Pa (data interval: 30 points), and the value obtained as G' when the stress (τ) was 2.4 Pa was adopted as the viscosity measurement value. .
In Examples 3 and 4, the agent after mixing was uneven (uniformity of the agent after mixing: evaluation ×), and in Comparative Example 4, white precipitation was observed in the agent after mixing. No viscosity measurements were made on the agents.

In addition, in order to evaluate the formation of the composite by the viscosity increase ratio, the viscosity values of the A agent, the B agent, and the mixed agent in each example and each comparative example measured above were used to calculate the following formula. was used to calculate the value of the viscosity increasing parameter (α) (not calculated for Examples 3 and 4 and Comparative Example 4).
Viscosity parameter (α)=(viscosity value of agent after mixing agent A and agent B)/{(viscosity value of agent A+viscosity value of agent B)/2}
When the value of this viscosity increasing parameter (α) is large, the actual viscosity of the agent obtained by mixing the agents A and B is higher than the theoretical viscosity value of the agent obtained by mixing the agents A and B. Therefore, it can be evaluated that a composite having excellent thickening property is produced.

(Evaluation results)
Tables 1 to 4 below show the sensory evaluation results and viscosity measurement results.

From the results shown in Tables 1 and 2, the formation of complexes was observed in the multi-agent cosmetics of Examples 1-4, while the formation of complexes was observed in the multi-agent cosmetics of Comparative Examples 1-5. I didn't. In addition, in Examples 3 and 4, although formation of a complex was observed, the agent after mixing was non-uniform (Table 1, Fig. 1). Moreover, Examples 1 to 3 showed excellent adhesiveness of the agent after mixing.
The viscosity parameter (α) of the multi-agent cosmetics of Examples 1 and 2 was larger than the viscosity parameter (α) of the multi-agent cosmetics of Comparative Examples 1-3 and 5. Therefore, it can be seen that Examples 1 and 2 produced composites that were more excellent in thickening than Comparative Examples 1 to 3 and 5.

From the results shown in Table 3, no complex formation was observed in the multi-component cosmetics of Comparative Examples 6-8. Also, the evaluation of adhesiveness of the multi-component cosmetic of Example 1 was excellent, but the evaluation of adhesiveness of Comparative Examples 6 and 7 was inferior.
Further, the viscosity parameter (α) of the multi-agent cosmetic of Example 1 was larger than the viscosity parameter (α) of the multi-agent cosmetic of Comparative Examples 6-8. Therefore, it can be seen that Example 1 produces composites with better thickening properties than Comparative Examples 6-8.

From the results shown in Table 4, the multi-agent cosmetics of Examples 1, 5 and 6 were found to form complexes. In addition, in the multi-component cosmetics of Examples 1, 5 and 6, the uniformity and adhesiveness of the components after mixing were excellent.
The viscosity increasing parameters (α) in the multi-agent cosmetics of Examples 1, 5 and 6 are the viscosity increasing parameters (α) in the multi-agent cosmetics of Comparative Examples 1 to 3 and 5 to 8 shown in Tables 2 and 3. was greater than Therefore, it can be seen that Examples 1, 5, and 6 produced composites that were more excellent in thickening than Comparative Examples 1-3 and 5-8. In addition, a difference was observed in the value of the viscosity increasing parameter (α) depending on the type of polyvinylpyrrolidone used (Examples 1, 5, 6).

Based on the evaluation procedure in the sensory evaluation, the mixed agents obtained by mixing each A agent and each B agent of Examples 1 to 6 and Comparative Examples 1 to 8 were left to stand on a flat surface, and then photographed. I took a picture. Photographed images are shown in FIGS.
From the results shown in FIGS. 1 to 4, in Examples 1 to 6, compared to Comparative Examples 1 to 8, the agent after mixing swelled upward, and formation of complexes was observed.
