Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a hair treatment composition. More specifically, the present invention relates to a hair treatment composition, particularly a hair conditioning agent, having high temperature stability of viscosity and excellent feeling in use.

[0002]

2. Description of the Related Art A hair treatment composition having a so-called conditioning effect for imparting smoothness and luster to hair and improving comb passage is generally referred to as a hair rinse, hair treatment, hair conditioner, hair pack, or the like. It is commercially available.

It is a known fact that many of these hair treatment compositions contain a quaternary ammonium salt as a main component, and the above-mentioned conditioning effect can be obtained by adsorbing the quaternary ammonium salt on the hair. .

For the purpose of improving gloss, smoothness, moist feeling, ease of cohesion, and the like, a higher alcohol is blended to form a so-called gel-like complex with a quaternary ammonium salt. The timely addition of oils, waxes, silicone compounds, natural and synthetic polymers is also known.

[0005]

However, the conventional hair treatment composition can impart smoothness or the like without sticking the hair at the time of application and rinsing, but it can be dried with a towel after rinsing. At the time of drying the hair, it has been difficult to impart a sufficiently satisfactory smoothness and unity effect after drying.

[0006] In the above-mentioned hair conditioning agent, a complex of a quaternary ammonium salt and a higher alcohol is often applied as a conditioning component. Since it is determined by the amount and the blending ratio, there are many restrictions on the formulation, and it is very difficult to adjust the viscosity to a desired one and to adjust the feeling in use.

Further, in the above-mentioned complex of a quaternary ammonium salt and a higher alcohol, the structure formed by the preparation method changes into a lamellar to vesicle-like form, and it is difficult to adjust the structure to a constant viscosity. The temperature dependence of the viscosity of the hair conditioning agent containing such a complex is closely related to the melting point of the above-described complex, and specifically, a rapid decrease in viscosity is observed at a temperature near the melting point, Along with this, the stability of the product also drops sharply.

On the other hand, for the purpose of solving the above-mentioned problems, thickeners commonly used in cosmetics and the like, for example, so-called polymer thickeners such as carboxyvinyl polymer and xanthan gum are used in these hair treatment compositions. In the case where it is blended, various inconveniences occur. For example, many of these polymeric thickeners are anionic polyelectrolytes, which form a complex with the cationic surfactant incorporated in the hair conditioning agent and cause precipitation, resulting in product stability and appearance. Not preferred. In addition, when a polymer thickener other than anionic is blended, undesired properties such as slimming peculiar to the polymer appear after washing.

[0009] In recent years, sensibility engineering techniques have been incorporated into the evaluation of product characteristics during cosmetic behavior, and it has been found that various factors are related to consumer preference for products. In particular, in the case of hair conditioning agents, various studies have been made in the past to improve the feel after washing, after towel drying, and after drying.However, by using the above-mentioned new study method, consumers can use products. The feeling of picking up in the hand has revealed that he is also interested in the process of applying and stretching hair. In such a process, it is important to adjust the flow characteristics (rheological characteristics) of the product so as to be preferred by consumers. Therefore, a hair treatment composition having an appropriate viscosity and excellent flow properties is desired.

The present inventors have conducted intensive studies in view of the above problems, and as a result, have found that a specific copolymer capable of associating in a water-soluble medium, thereby increasing the viscosity of the water-soluble medium, and a cationic interface.
