Description

The present invention relates to a hair rinse composition, and more specifically, it can give a supple and moist finish without giving the hair stickiness and weight while increasing the moisture retention of the hair, and at low humidity. The present invention relates to a hair rinse composition that is excellent in preventing rustiness and moisture.

Women's hairstyles are also changing the finish and feel of hair that are required with the trend. Recently, hair styles with a reduced volume of hair ends such as shaggy and layer cut are common. On the other hand, there is a demand not only for a soft and moist finish, but also for a feeling of stickiness and a texture that gives a volume without making hair heavy, by performing treatments such as coloring and perming. Furthermore, it is desired that these functions continue even in a low humidity environment in winter. In conventional hair rinse compositions such as hair rinses and hair treatments, cationic surfactants and silicones are blended for the purpose of softening the hair and improving the combing, and in order to give a moist feel, Solid oil is blended. However, with these conventional techniques, it is difficult to satisfy the needs required in recent hairstyles, and it has been a challenge to achieve both a moist finish and a lack of stickiness and weight.

As a method for solving these problems, for example, a hair cosmetic (for example, see Patent Documents 1 to 4) that imparts smoothness and flexibility to hair by using a fatty acid amidoamine compound or a hydroxyetheramine compound is proposed. ing. In addition, for the purpose of imparting gloss and smoothness to hair, it is known to blend an amino-modified silicone emulsion (see, for example, Patent Documents 5 and 6).

In addition, glucosamine and its salts are added to hair treatment agents for hair color for the purpose of giving hair good moisturizing properties and a pleasant smooth feeling (see, for example, Patent Document 7), and sugar amines such as N-acetylglucosamine. Applying a combination of products that are consumed orally and topically applicable hair care products such as conditioners for the purpose of adjusting hair condition such as hair texture, cleanliness, feel and hair strand arrangement (for example, However, it is not known to give a supple and moist finish by increasing the moisture retention of hair by blending with an amino-modified silicone emulsion in a hair rinse. It was.

Judgment criteria are as follows.
◎: Very good ... more than 16 test subjects who answered "good" ○: Excellent ... 11-15 test subjects who answered "good" △: Inferior ... The number of test subjects who answered "good" is 6 to 10 ×: Very inferior ... The number of test subjects who answered "good" is 5 or less

(4) No rustiness in a low humidity environment, moist feeling Commercially available black hair (10 g, 15 cm, manufactured by Beaulux) was shampooed with 2 g of 10% polyoxyethylene (2E.O.) sodium lauryl ether sulfate. After thoroughly rinsing with hot water, 2 g of the hair rinse composition of the present invention was applied, rinsed thoroughly with hot water, towel-dried, and dried in an environment of 25 ° C. and 60% humidity for 6 hours. Next, let it stand in a low humidity environment (25 ° C, 30% humidity) for 12 hours, and in terms of non-pumpiness and moist feeling, there are three levels of “good”, “normal”, and “bad” depending on the panel of 20 people. Judgment was made based on the number of people who answered “good” as a result of the determination.
Judgment criteria are as follows.
◎: Very good ... more than 16 test subjects who answered "good" ○: Excellent ... 11-15 test subjects who answered "good" △: Inferior ... The number of test subjects who answered "good" is 6 to 10 ×: Very inferior ... The number of test subjects who answered "good" is 5 or less
