JP5099686B2 - Transparent cosmetic for hair - Google Patents

Description

  The present invention relates to a transparent cosmetic for hair.

  In hair cosmetics, an anionic surfactant permeates moisture into hair and imparts moisture. In addition, the cationic surfactant imparts smoothness and softness to the hair and improves the feeling of touch and combing.

  However, when an anionic surfactant and a cationic surfactant are used in combination, there is a problem in that a complex is formed in the composition, and precipitates and lumps are generated and become cloudy. In particular, in the case of transparent cosmetics, it was not transparent, and formulation was very difficult. Moreover, even if it can be made transparent, it has been difficult to maintain transparency over time.

  Until now, attempts have been made to use an anionic surfactant and a cationic surfactant together in transparent cosmetics. For example, a transparent hair rinse composition containing a monoalkyl type quaternary ammonium salt type cationic surfactant, a carboxylate type anionic surfactant, and a specific alcohol (see, for example, Patent Document 1) A transparent hair conditioning composition (for example, see Patent Document 2) containing a cationic surfactant and a highly alkoxylated anionic surfactant has been proposed.

However, although these attempts can temporarily suppress the formation of complexes in the composition, problems such as precipitates and lumps being formed over time, resulting in poor stability of the preparation, and transparency persistence. There is a problem of being inferior. In addition, when these compositions are made liquid, there is still a problem that precipitates and lumps are generated and become cloudy.

(Test Example 3: Evaluation of smoothness and moisture)
0.4 g of the cosmetics obtained in each Example and each Comparative Example was applied to a hair bundle (length 10 cm, width 0.8 cm, weight 1 g) left overnight at 23 ° C. and humidity 60%. Thereafter, the hair was stretched with a fingertip to make the hair bundle uniform. Again, after leaving for 30 minutes under the above conditions, the evaluation and sensory evaluation of the smoothness and moisture of the hair bundle were performed by 20 evaluation panels according to the following evaluation criteria.

<Evaluation criteria for smoothness>
