JP2837489B2 - Cleansing composition for hair - Google Patents

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a hair cleansing agent, and more specifically, has a high foaming property and a good detergency against sebum, and has a sufficient function as a shampoo. And, by effectively adsorbing the silicone derivative to the hair surface by the action of the hydrocarbon-based oil, the suppleness of the hair in the wet state after shampooing, the smoothness and the suppleness of the hair after drying,
The present invention relates to a hair cleansing composition having excellent usability such as smoothness.

[Prior art] Conventionally, a quaternary nitrogen-containing water-soluble polymer has been widely used as a conditioning component of a hair cleansing agent.
It is excellent in suppressing tangling and snagging of paper during shampooing and giving a smooth feel, and is compounded and used in cleaning agents such as shampoos.

However, these can improve the smoothness during rinsing, but after towel drying and during drying, no effect of improving the smoothness and suppleness of the paper is observed, and conversely, these large amounts of Tended to lead to hair crackling, hair fly, etc.

In addition, various silicone derivatives can be considered as components for improving the smoothness of the hair, but if they are simply blended into a cleaning base such as a normal shampoo, the adsorptivity to the hair surface is low, which is expected. No sufficient effect was obtained. Furthermore, depending on the cleaning base of the shampoo, foaming and detergency are significantly reduced due to the addition of the silicone derivative, resulting in a shampoo having no shampoo function.

[Problem to be Solved by the Invention] The present invention has been found under the above background,
In addition to having the function of a shampoo with high foaming and sufficient detergency, it also has a smooth feel after towel drying and smooth and calm hair even after a complete trial without causing gowatsuki or hair fly. The present invention relates to a hair cleansing composition that can be used.
