Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol-type hair treatment composition, and more particularly, to a spray from a nozzle of an aerosol container. The present invention relates to a spray foam type aerosol hair treatment composition which disappears at an appropriate speed and has good familiarity with the hair, and imparts smoothness and softness to the hair.

[0002]

2. Description of the Related Art A so-called spray foam, which is sprayed from a nozzle of an aerosol container and adheres in a foam when reaching hair, can be applied directly to hair, so that hands are not stained. It has been used in hairdressing products and the like as an easy-to-use product form because it has features such as the location of the part to be applied and the injection amount are easy to control because the part becomes white and foamy.

On the other hand, as a treatment agent for hair, a cationic surfactant is effective because it has good affinity and adsorption to hair, and the treatment effect is enhanced by using it in combination with a cationic surfactant. Higher alcohol has also been used as a lot.

[0004]

However, most of the hair treatment agents of the type in which a cationic surfactant and a higher alcohol are used in combination, are first applied to the hair and then applied to the hair, and the hands are washed later. It was difficult to use, especially when used in the out bath. Therefore, it was considered to improve usability by making this hair treatment agent a spray foam type, but the structure of the system derived from the interaction between the cationic surfactant and the higher alcohol eliminated the foam after spraying. Since it is difficult to remove the bubbles, it takes a long time for the foam to disappear, so that the hair does not fit well and a hair treatment agent of sufficient quality could not be obtained. Therefore, there has been a demand for the development of a spray foam type hair treatment agent that foams disappear in an appropriate period of time and has good familiarity with hair, and can impart smoothness and softness to hair.

[0005]

[Means for Solving the Problems] In view of such circumstances,
As a result of intensive studies to overcome the above drawbacks, the present inventors have found that a composition (stock solution) consisting of a specific amount of a higher alcohol, a cationic surfactant and a lower alcohol, and a specific ratio of liquefied petroleum gas and dimethyl ether. By further mixing a propellant consisting of a mixture at a specific ratio and filling the aerosol container, it is sprayed from the nozzle of the aerosol container in a spray form, and when it reaches the hair, it adheres in the form of foam, and the foam is still formed. It has been found that a spray foam type aerosol type hair treatment composition which disappears at a moderate speed and is well adapted to the hair and imparts smoothness and softness to the hair can be obtained, and based on this finding, the present invention has been completed.
