Description

TECHNICAL FIELD The present invention relates to a hair rinse agent having excellent combability and antistatic properties for hair.

2. Description of the Related Art Generally, when washing hair, the oil and fat components on the hair surface are removed together with the dirt attached to the hair. Therefore, when brushing in a low-humidity environment, static electricity is generated due to friction, causing hair fly, which causes hair damage by excessive brushing. Therefore, the chargeability of the hair,
Reducing frictional resistance also has important implications for maintaining hair health.

For this purpose, a post-wash hair rinse agent is used to restore the deteriorated properties of the hair.

Conventionally, hair rinse agents mainly contain quaternary ammonium salts represented by dialkyldimethylammonium chloride and alkyltrimethylammonium chloride and contain higher alcohols, oils and fats, hydrocarbons, esters, stabilizers, fragrances, dyes, water and the like. In addition, it is made. The quaternary ammonium salt must be adsorbed on the hair in order to prevent "xime" and "tangling" of the hair after washing and to improve the dry finish.

However, conventional hair rinse agents have insufficient persistence of adsorption of quaternary ammonium salts during rinsing, and are not sufficiently satisfactory in combability and antistatic properties of hair.

An object of the present invention is to provide a hair rinse agent having excellent combability and antistatic properties.

Means and Actions for Solving the Problems In order to solve the above-mentioned problems, the present inventors have conducted research by blending quaternary ammonium salts with various additives such as water-soluble polymers Has been completed.

That is, the present invention provides (A): general formula (I) [In the formula, R ₁ is one selected from an alkyl group having 10 to 24 carbon atoms, an alkenyl group and a hydroxyalkyl group,
R ₂ is one selected from an alkyl group having 1 to 3 carbon atoms, an alkyl group having 10 to 24 carbon atoms, an alkenyl group and a hydroxyalkyl group, and R ₃ and R ₄ are alkyl groups having 1 to 3 carbon atoms. And X represents a halogen atom or a methylsulfate residue] at least one quaternary ammonium salt 0.1
~ 10% by weight, (B): general formula (II) [In the formula, R ₅ represents an alkyl group having 1 to 4 carbon atoms or a hydrogen atom, R ₆ and R ₇ are alkyl groups having 9 to 21 carbon atoms,
Is an alkenyl group, X and Y are positive integers representing the degree of polymerization of the oxyethylene group, and X + Y is 110 to 150].
Weight% and (C): Chemical formula (III) [Wherein n represents an integer of 10 to 100] and contains at least one N-acetyl-D-glucosamine polymer of 0.05 to 10% by weight, and has a pH of 3.5 to 5.5. The present invention relates to a hair rinse agent characterized by:

The first essential component (A) of the present invention is the above general formula (I).
Which corresponds to a long-chain monoalkyl quaternary ammonium salt or a long-chain dialkyl quaternary ammonium salt. The long-chain alkyl group has 10 to 24 carbon atoms, and may contain a double bond or a hydroxy group, but the preferable carbon number is 12 to 22. The carbon number of the long-chain alkyl group is an essential factor for the performance of the hair rinse agent of the present invention. That is, the carbon number
When it is less than 10, the effect of imparting flexibility and suppleness to the hair is reduced, and when the carbon number exceeds 24, the hair becomes stiff and hard and the effect of imparting flexibility is reduced. On the other hand, when the number of carbon atoms is within the above range, the hair rinse agent has an appropriate hydrophobicity and thus has an affinity for the hair, and also has an appropriate water retention property, so that it has an effect of imparting flexibility and suppleness to the hair. To be demonstrated. Further, when X constituting the anion of the quaternary ammonium salt is a halogen atom or methylsulfate, the hair rinse agent has appropriate hydrophobicity and water retention.

The amount of the quaternary ammonium salt compounded is 0.1 to 10% by weight, preferably 1.0 to 2% by weight, based on the entire hair rinse agent. 0.
If it is less than 1% by weight, combability and antistatic property are insufficient, and if it exceeds 10% by weight, stickiness is caused on the hair, which is not preferable.

The second essential component (B) of the present invention is the above general formula (II)
A glucose derivative represented by, for example, polyoxyethylene (120 mol) methyl glucose dilaurate, posioxyethylene (120 mol) methyl glucose dioleate, polyoxyethylene (120 mol) methyl glucose diisostearate, polyoxy Ethylene (14
0 mol) methyl gucose diisostearate and the like. The blending amount of these glucose derivatives is 0.05 to 10% by weight, preferably 0.1 to 5% by weight, based on the entire hair rinse agent. If it is less than 0.05%, the tips of the hairs become dull, and if it exceeds 10% by weight, stickiness is caused, which is not preferable.

The third essential component (C) of the present invention is represented by the above chemical formula (II
It is an N-acetyl-D-glucosamine polymer represented by I), and its content is 0.05 to 10% by weight, preferably 0.5 to 5% by weight, based on the entire hair rinse agent. If the amount is less than 0.05% by weight, the tips of the hairs will become dry, and if the amount exceeds 10% by weight, stickiness will occur, which is not preferable.

Other optional components can be added to the hair rinse agent containing the essential components described above within a range that does not affect the effects of the present invention.

That is, as an optional component, hydrocarbons such as liquid paraffin, petrolatum, solid paraffin, squalane and olefin oligomer, isopropyl myristate,
Isopropyl palmitate, stearyl stearate,
Esters such as octyldodecyl myristate, octyldodecyl oleate and ethylhexanoic acid triglyceride, emulsifiers such as polyoxyethylene stearate and polyoxyethylene sorbitan monolaurate, N- (2-hydroxyethyl) -N- [bis (2

The combability and antistatic property were measured as follows.

[Combability] Comb through, untangled hair bundle (25-27cm, 20-30g)
Using a nylon brush with a tension meter, pass the comb at a constant speed (30 cm / sec). At that time, read the maximum load applied to the brush from the tension meter. The maximum load before and after rinsing the same hair bundle is 30
Measure each time and find the average value. From the following formula, the combability was defined as the reduction rate of the maximum load before and after the rinse treatment.

C _B : average value of maximum load (g) before rinsing C _A : average value of maximum load (g) after rinsing The combing evaluation was performed according to the following criteria.

30% or more: ◎ (very good) 20 to 30%: ○ (good) 10 to 20%: △ (normal) 0 to 10%: × (bad) [Antistatic] Combing, entangled hair bundles (25-30 cm, 10 g) is combed with a celluloid comb 30 times within a fixed time (15 seconds), and the electrostatic voltage is measured with an electrostatic checker (Nippon Kayaku). For the same hair bundle, the antistatic property was defined as the rate of decrease in static voltage before and after the rinse treatment. The measurement conditions are 17-
20 ℃, 65-70% RH.

Q _B : Static voltage before rinsing Q _A : Static voltage after rinsing The static voltage was evaluated according to the following criteria.

95% or more: ◎ Very good 85-95%: ○ Good 75-85%: △ Normal 65-75%: × Poor 65% or less: × × Inferior As is clear from the results shown in Table 1, when the water-soluble polymer was other than the component C, satisfactory combing properties and antistatic properties were not obtained.

Even if the water-soluble polymer is an essential component of the present invention, pH
When the value was out of the range of 3.5 to 5.5, combability and antistatic property were insufficient.

That is, it is understood that when the essential components of A, B and C and the pH satisfy the conditions of the present invention, excellent combability and antistatic property are exhibited.
