Abstract

PURPOSE:To obtain a hair treatment capable of giving respectively strong soft touch, gloss, adsorption, smoothness, combability and antistatic properties and improved in durability. CONSTITUTION:This hair treatment contains a quaternary ammonium salt having a counter ion composed of fumaric acid, e.g. a compound of formula I (R1 is a 12 to 22C alkyl; R2 to R4 are a 1 to 5C alkyl, a hydroxyalkyl; X is fumaric acid), formula II (R5 and R5 are each a 12 to 18C alkyl; R7 to R8 are each a 1 to 2C alkyl), formula III (R9 is a 12 to 18C alkyl; R10 and R11 are each methyl), formula IV (R12 is a 12 to 16C alkyl) or formula V (R13 is a 12C alkyl). The mixture ratio of the compound is preferably 0.3 to 10wt.% in the case of a linse, a treatment, etc., which are each a type to be washed away and 0.05 to 2.0wt.% in the case of a blowing agent, a hair-setting agent, etc., which are each a type not to be washed away.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention provides a soft feeling for hair,
The present invention relates to a hair treatment agent capable of strongly imparting an antistatic effect such as luster, adsorption, slippage, combing, and high durability.

[0002]

2. Description of the Related Art Conventionally, hair is physically damaged by combs, brushes, dryers, hair washes, and permanent waves,
It is easily damaged by chemicals such as hair color, and has many problems such as hardness, dryness, slippage, and loss of luster.
To solve this, rinses, treatments, etc. are used, but their effects and sustainability are not satisfactory. Further, various additives are blended in order to reduce damage to permanent waves, hair color, etc. and to make hair easier to handle, but they are not satisfactory in any case. These content components are generally quaternary ammonium salts, anionic activators, nonionic activators, higher alcohols, fatty acid esters, hydrocarbons, polyhydric alcohols,
It is made of a combination of silicone oil and the like.

Among these combinations, a quaternary ammonium salt is used as an important raw material in order to prevent physical and chemical damage and to improve texture. Currently, the counterions of quaternary ammonium salts are monovalent anions such as chlorine, bromine and saccharin. The characteristics of this quaternary ammonium salt are: comb-like, antistatic effect, softness, adsorption,
Although they are slippery, the effects are weak, and in order to supplement these, it is a product in combination with other raw materials, but it is not satisfactory, and the sustainability is also weak and satisfactory. Absent. Despite the strong demand for products that have improved these, there has been no hair treatment agent having a strong effect and a long-lasting effect.

[0004]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to strongly impart an antistatic effect to the hair treatment agent such as softness, luster, adsorption, slippage, combing, and improve the durability. It is what

[0005]

Means for Solving the Problems As a result of intensive studies, the present inventor has found that by using a quaternary ammonium salt composed of fumaric acid whose counter ion is a divalent ion, the softness and gloss The inventors have found a hair treatment agent having a strong antistatic effect such as adsorption, slippage, combing, and high durability, and completed the present invention. That is, the hair treatment agent is characterized by containing a quaternary ammonium salt whose counter ion is fumaric acid. In the present invention, the hair treatment agent refers to one that is widely applied to hair, and includes, for example, rinse, treatment, blowing agent, hair setting agent, hair spray, hair color, permanent wave and the like.
Hereinafter, the present invention will be described in detail. The structural formula of the quaternary ammonium salt whose counter ion is fumaric acid has the following structure.
