Description

[Detailed description of the invention] The present invention relates to shampoo compositions.

More specifically, this shampoo has a rinsing effect that makes the hair supple and smooth after washing, and has an excellent conditioning effect that eliminates the hair fly phenomenon caused by the generation of static electricity after drying the hair, significantly improves the combability, and improves the ease of passing through the plan. The present invention relates to a composition. Recently, many shampoo compositions containing cationic polymers such as cationic cellulose, which are characterized by imparting conditioning effects to washed hair, have been proposed and put on the market.
Such shampoos are generally referred to as conditioning shampoos, but in addition to containing a cationic polymer as an essential ingredient, an amphoteric surfactant must be used as a cleansing active ingredient. The basic properties of products, such as foaming properties and cleansing properties, are poor (this decline in performance is particularly noticeable when washing hair that has hair styling products attached), and furthermore, the foaming properties and cleansing properties that are the basic properties of products are poor. The remaining cationic polymer and amphoteric surfactant complex (
Complex) hardens as the hair dries, causing hair fries and other problems, resulting in insufficient conditioning effects. In addition, the formulation of the shampoo composition changes over time, resulting in discoloration, odor loss, and other fatal drawbacks.

Some of these drawbacks of conditioning shampoos containing an amphoteric surfactant and a cationic polymer as essential ingredients can be improved by replacing the amphoteric surfactant as a cleaning active ingredient with an anionic surfactant. However, even when the shampoo composition is diluted with salt water in the condition of hair washing, the complex of anionic surfactant and cationic polymer does not precipitate and remains solubilized in the aqueous solution, and the cationic polymer does not exhibit any conditioning effect. The original purpose of adding and blending is not achieved.

As for methods for complex precipitation between anionic surfactants and cationic polymers, attempts have been made to use salt in combination, increase the amount of cationic polymers, etc., but all of these methods have insufficient conditioning effects. There are drawbacks such as heating and, conversely, making the hair less slippery, and further improvements are desired. The present inventors have carried out intensive research to improve the drawbacks of the Jump composition using a cationic polymer as a conditioning effect-imparting agent.
Unexpectedly and surprisingly, the addition of a silicone derivative to Jump's composition, which has an anionic surfactant and a cationic polymer as essential ingredients, resulted in a product that has excellent conditioning effects and is stable over time. It was discovered that a Jump composition with excellent cleaning and foaming properties can be obtained, and the present invention was developed.
