Abstract

PROBLEM TO BE SOLVED: To obtain a hair rinse agent composition, capable of uniformly applying to hair, having high rinsing effect and excellent in feeling to user and persistency of effect by combining an oily component with specific two kinds of surfactants and using a specific amount of water. SOLUTION: This hair rinse agent composition is obtained by combining (A) 20-60wt.% oily component with (B) 20-70wt.% nonionic surfactant, (C) 1-20wt.% cationic surfactant and diluting the mixture with <=15wt.% water so as to instantaneously uniformly disperse these components by self- emulsification. A material selected from among liquid paraffin, higher alcohol and silicone oil is preferably used as the component A. A surfactant selected from among a glycerin monofatty acid ester, a glycerin difatty acid ester and a polyoxyethylene sorbitane fatty acid ester is preferably used as the component B. Especially, trimethylmonostearyl ammonium chloride, etc., is preferably used as the component C.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair rinse composition which can be uniformly applied to hair, has a high rinsing effect, and has excellent feeling of use and durability of effect.

[0002]

2. Description of the Related Art Generally, a hair rinse composition contains a cationic surfactant, an oil component, etc., and these components are adsorbed to the hair to make the surface of the hair smooth,
It has the functions of improving combability, preventing static electricity, and protecting the surface of hair. Such a hair rinse composition is used by applying it to hair after washing and then rinsing.

However, since the conventional hair rinse composition is used by directly applying it to the hair or extending it, it is difficult to apply it uniformly to the entire hair. Especially for long hair, there is a problem that it is more difficult and time-consuming. Further, there is a problem that the effect is significantly reduced if the hair rinse composition is rinsed off in a state where it is not uniformly applied.

Furthermore, when a conventional hair rinse composition is used by diluting it, oil properties may be suspended or some components may be precipitated due to its properties, etc. Was impossible to disperse.

[0005]

Therefore, an object of the present invention is to provide a hair rinse composition which can be uniformly applied to hair, has a high rinsing effect, and is excellent in the feeling of use and the durability of the rinsing effect. Especially.

[0006]

Under such circumstances, the inventors of the present invention have conducted diligent research, and as a result, if an oily component, a nonionic surfactant and a cationic surfactant were used in combination, When self-emulsifying, it instantly disperses evenly, and can be easily and evenly applied to the hair, with a high rinse effect, and a hair rinse composition with excellent feeling of use and long-lasting rinse effect is obtained. Therefore, the present invention has been completed.

That is, the present invention relates to (A) an oil component,
A hair rinse composition containing (B) a nonionic surfactant and (C) a cationic surfactant and having a water content of 15% by weight or less.
