Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair conditioner, and more particularly to a hair conditioner composition which greatly improves the luster and moisturizing feel of hair and is also excellent in other hair conditioning effects.

[0002]

When the hair is washed with a shampoo containing an anionic surfactant as a main component in order to remove stains on the hair, not only stains on the hair but also oil components protecting the hair surface are removed. It is removed at the same time, resulting in dull, poor combing hair, and more likely to cause hair damage, split ends, and cut hair.

Therefore, for the purpose of preventing these adverse effects, a hair rinse agent containing a quaternary ammonium salt which is a cationic surfactant as an active ingredient is used.

These hair rinse agents have a conditioning effect on the hair (softness, moisturizing, smoothness,
The purpose is to impart combability and luster), but the quaternary ammonium salt alone cannot provide a sufficient effect in terms of luster, moistness and smoothness. Therefore, it has been proposed to blend oils and fats such as higher alcohols, glycerides and liquid paraffin in conventional hair rinse agents in order to improve these drawbacks. In recent years, hair care products using silicone gum have also been proposed for the purpose of improving the luster and smoothness of hair.

However, in the hair care products using these silicone gums, the silicone gums adhered to the hair are partially detached in the process of continuous use by consumers, and a product having satisfactory smoothness, combability and luster is obtained. The reality was that it was not done.

[0006] That is, an object of the present invention is to provide a hair rinse agent which has an appropriate releasability upon washing and which greatly improves the luster, smoothness and moisturizing feeling of hair.

[0007]

In order to achieve the above object, the hair rinse composition of the present invention has the following constitution. That is, the general formula (A)

[Chemical 4] (In the formula, 1-2 of R _{1 to} R ₄ represent a long-chain alkyl group having 12 to 24 carbon atoms, the rest represent an alkyl group having 1 to 3 carbon atoms or a benzyl group, and X represents a halogen atom. .) 0.3 to 5% by weight of one or more quaternary ammonium salts represented by the general formula (B).

Embedded image (wherein R ₅ are all methyl groups or a part thereof is a phenyl group (provided that 90% or more of the total number of R ₅ are methyl groups), and R ₆ are all methyl groups or One represents a hydroxyl group, and n represents an integer of 300 to 800.) One or more silicones represented by 0.1 to 2% by weight and the general formula (C).

(Wherein R ₇ are all methyl groups or a part thereof is a phenyl group (provided that 90% or more of the total number of R ₇ are methyl groups), and R ₈ are all methyl groups or one of them). Is a hydroxyl group, m is an integer of 20 to 60, n is an integer of 2 to 6, and a and b are each an integer of 10 to 30). 2% by weight of the hair rinse composition.

As the quaternary ammonium salt represented by the above general formula (A) in the present invention, all that can be used in ordinary hair rinse agents and the like are used. For example, dimethyldioctadecyl ammonium chloride,
Octadecyltrimethylammonium chloride, dodecyltrimethylammonium chloride, benzyldimethyloctadecylammonium chloride, didodecyldimethylammonium chloride, benzyldiethyldodecylammonium chloride, hexadecyltrimethylammonium chloride, dodecyltrimethylammonium bromide, docosyltrimethylammonium chloride, didodecyldimethylammonium bromide , And so on.

In the hair rinse composition of the present invention, one or a mixture of two or more of these cationic surfactants is preferably 0.3 to 5% by weight (hereinafter abbreviated as wt%) based on the total amount. Is mixed in an amount of 0.5 to 4 wt%. When the content is less than 0.3 wt%, good results on the hair conditioning effect cannot be obtained, and when it exceeds 5 wt%, the hair becomes sticky, which is not preferable.

Examples of the silicone represented by the general formula (B) in the present invention include dimethylpolysiloxane, methylphenylpolysiloxane, terminal hydroxyl group-containing dimethylpolysiloxane, terminal hydroxyl group-containing methylphenylpolysiloxane, and the like. In the formula, all R _{5 s} are methyl groups or a part thereof is a phenyl group, and it is essential that the ratio of methyl groups is 90% or more of the total number of R ₅ .

In the hair rinse composition of the present invention, 0.1 to 2 wt%, preferably 0.2 to 1 w, of the mixture of one or two or more of these silicones based on the total amount.
t% is compounded. If the blending amount is less than 0.1 wt%, a good result on the moist feeling after drying cannot be obtained, and if it exceeds 2 wt%, the hair becomes heavy, which is not preferable.

On the other hand, the average degree of polymerization n of the silicone used in the present invention is 300 to 800, preferably 400 to 800.
It is 700. Those having an average degree of polymerization of less than 300 are not effective, and those having an average degree of polymerization of more than 800 are not preferable because they are not smooth and glossy when continuously used.

Examples of the polyether-modified silicone represented by the general formula (C) in the present invention include dimethylpolysiloxane-polyoxyalkylene block copolymer, methylphenylpolysiloxane-polyoxyalkylene block copolymer, and terminal. Examples thereof include a hydroxyl group-containing dimethylpolysiloxane-polyoxyalkylene block copolymer and a terminal hydroxyl group-containing methylphenylpolysiloxane-polyoxyalkylene block copolymer.

The hair rinse composition of the present invention contains 0.1 to 2% by weight, preferably 0.2 to 1% by weight, based on the total amount of one or a mixture of two or more of these polyether-modified silicones. It Compounding amount is 0.1wt
When it is less than 2% by weight, good moist feeling after drying cannot be obtained, and when it exceeds 2% by weight, tackiness is caused on the hair, which is not preferable.

The hair rinse composition of the present invention comprises the above-mentioned three components as essential constituents.
Other components may be appropriately blended within the range that achieves the object of the present invention.
