Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning agent, and more particularly, to a cleaning agent for hair shampoo, facial cleansing agent, body shampoo, animal shampoo, etc. that is stably blended with hyaluronic acid. Regarding drugs.

[Prior Art] Hair shampoos are widely used by both men and women, primarily to cleanse the hair.

On the other hand, hyaluronic acid has recently attracted attention as a moisturizing agent for cosmetics, and numerous patent applications have been filed for cosmetics containing it. It has been reported that hyaluronic acid is also useful as a component of hair cosmetics; for example, JP-A-59-186911 describes a hair shampoo containing hyaluronic acid.

[Problems to be Solved by the Invention] By the way, anionic surfactants, amphoteric surfactants, etc. are generally used as the active main ingredients of hair shampoo, and the above publication also discloses that anionic surfactants and amphoteric surfactants are used as the main ingredients. An activator is used.

However, when the present inventors added hyaluronic acid to a hair shampoo containing an anionic surfactant or an amphoteric surfactant as a main ingredient, the anionic surfactant or amphoteric surfactant and hyaluronic acid reacted. It was found that an insoluble white gel-like precipitate was formed, which was thought to have been produced by the process. This kind of hair shampoo has the effects of "foaming" and "cleansing power" which are the characteristics of anionic surfactants and amphoteric surfactants, and the "moisturizing" and "cleaning power" which are the characteristics of hyaluronic acid. It also lost its lustrous effect and was found to be unsuitable as a product as it is.

Therefore, an object of the present invention is to provide hair shampoos and other cleansing agents that stably contain hyaluronic acid.

Test Example 1 When blending component (A) with component (B), which is the main component of the cleaning agent, the effect of suppressing precipitation formation when components (C), (D), and (E) were added was evaluated using the following method. The test was conducted.

(Test method) Each component other than sodium hyaluronate (A) shown in Table 1 was heated and dissolved at 80°C, and to this was added sodium hyaluronate (A) dissolved in a portion of purified water. The solution was cooled and used as a test solution.

Pour 100ml of this solution into a sealed sample container and
It was left in a constant temperature bath at 125°C or 5°C, and after one month, it was observed with the naked eye and evaluated according to the following criteria. The results are shown in Table 1.
Shown below.

○: No precipitate △: Slight precipitate ×: Precipitate present (blank below) As is clear from Table 1, when component (A) is blended into a product containing all components (B) to (E) Only the formation of precipitates is suppressed.

Examples 1 to 5 Hair Shampoo Components (1) to (phase) in Table 2 were heated and mixed with a part of @, and a solution of component (1) heated and dissolved in the remaining part of @ was added at 80° C. and mixed with stirring. Next, component Φ was added at 55°C to obtain a hair shampoo.

(Margin below) Table 2 (%) Test Example 2 The hair shampoo of Example 4 was subjected to a feel-of-use comparison test with a hair shampoo having the same composition except that sodium hyaluronate was not mixed therein by the following method. The results are shown in Table 3.

Target: 49 men and women aged 20-47 (average 39 years old)
(38 women, 11 men) Method: Two types of samples were tested for use for two weeks on each side for a total of four weeks, and each item was compared and evaluated based on the following criteria.
