Description

[0001] Hair conditioning composition [0002]

The present invention relates to a hair conditioning composition, and more particularly, to a hair conditioning composition having less slip during rinsing and superior hair conditioning effect after drying.

Recently, as the level of living has improved, interest in beauty has been increasing, among which beauty of hair is also an important part. According to this trend, a variety of hair cosmetic products such as dyed products and permanent products have been researched and commercialized.

However, frequent dyeing, permanent hair is easy to damage hair, and this damaged hair has no gloss, it is rough and it is difficult to trim hair. Also, even in case of healthy hair, if only shampoo is used, oil is removed from hair due to excessive cleaning, and it is difficult to maintain calm hair due to lack of gloss and static electricity.

Therefore, in order to overcome this, an emulsion type conditioner composed of a hair conditioning material such as a high alcohol, a cationic surfactant, water and silicone is generally used. However, a conditioner with a high amount of high alcohol will leave excess oil in the hair and adversely affect the scalp, making it unsuitable for people with thin hair or sensitive scalp. To this end, a rinse with no or high alcohol content is circulating in the market, but hair conditioning is less effective.

For example, U.S. Patent Application Publication No. 2003/0216267 discloses a transparent conditioner, but it does not contain a high-grade alcohol and thus has a disadvantage that the overall condition is less effective. U.S. Patent No. 6,365,142 discloses an emulsifying system in which a tertiary alkylamine is neutralized, a fatty alcohol, and a silicone conditioning agent. However, the emulsifying system has a disadvantage in that a rich feeling and excellent conditioning effect are expected during use, but there is a lot of slippery during rinsing.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a hair conditioning composition which has a low content of high-alcohol content and which is less slippery during rinsing, and which does not deteriorate overall feeling upon application and after drying.

In order to solve the above problems, the hair conditioning composition of the present invention comprises a polyacrylate-1 crosspolymer cationic carbomer; A glyceryl oxyhydroxypropylalkyldimonium chloride cationic surfactant represented by the following formula (1)

A linear or branched alkyl group in formula 1 R is C _{12 ~ 18,} an alkenyl group, or combinations thereof; And higher alcohols.

The hair conditioning composition of the present invention may further comprise a quaternary cationic surfactant and / or a water-insoluble nonvolatile silicone compound, if necessary, having a specific structure.

The hair conditioning composition of the present invention is excellent in the conditioning effect of wetting and drying after rinsing with little slipperyness.

Hereinafter, the present invention will be described in detail. The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms and the inventor may appropriately define the concept of the term in order to best describe its invention It should be construed as meaning and concept consistent with the technical idea of the present invention.

The polyacrylate-1 crosspolymer contained in the hair conditioning composition of the present invention is a polyacrylate-1 crosspolymer, which is an aminoacrylate copolymer having a C _1-4 alkyl (meth) acrylate and an amine functional group , And a commercially available product (Aqua CC from Noveon).

The polyacrylate-1 crosspolymer according to the present invention has a function of improving the viscosity in the cationic surfactant base in the hair conditioning composition of the present invention, which has a lower alcohol content than that of the conventional hair conditioning composition, The dispersion stability is also excellent.

The content of the polyacrylate-1 crosspolymer according to the present invention may be appropriately determined according to need, and may be, for example, 0.1 to 5% by weight based on the total weight of the composition, but is not limited thereto. If the content of the polymer is less than 0.1% by weight, the effect of increasing the viscosity may be insignificant. If the content of the polymer is more than 5% by weight, the viscosity may be too high.

In order to improve the viscosity with the polyacrylate-1 crosspolymer according to the present invention, the pH condition must be controlled. The viscosity of the polyacrylate-1 cross polymer according to the present invention is such that the viscosity does not decrease even after an increase in pH. Therefore, it is usually necessary to introduce a desired viscosity at an acidic pH of 3 to 4 and then to adjust the pH to a proper value with a basic substance.

As the acid for making the acidic condition, a usual inorganic acid or organic acid such as citric acid, lactic acid, glycolic acid, phosphoric acid, acetic acid, hydrochloric acid and the like can be used And basic materials such as triethanol amine, monoethanol amine, sodium hydroxide (NaOH) and potassium hydroxide (KOH) are used as the basic substance.

If the content is less than 1% by weight, the effect as an emulsifier may be insignificant. If the content is more than 10% by weight, an additional conditioning effect can not be expected to increase.

As the higher alcohol contained in the hair conditioning composition of the present invention, there can be used a high alcohol which can be commonly used in the art, wherein the higher alcohol means an aliphatic alcohol having 6 or more carbon atoms contained in one molecule .

Preferably, the higher alcohols that may be used in the present invention may be represented by the following formula:

The content of the higher alcohol according to the present invention is not particularly limited and may be appropriately determined, for example, 1 to 10% by weight, preferably 1 to 5% by weight based on the total weight of the composition. If the content of the higher alcohol is less than 1% by weight, the effect of correcting may be insufficient. If the content is more than 10% by weight, excessive rubbing may occur during rinsing.

The hair conditioning composition of the present invention may contain a quaternary cationic surfactant, a silicone compound, water and the like which are conventionally used in hair conditioning compositions in addition to the above-mentioned active ingredients.

Quaternary cationic surfactants that may be included in the present invention include, but are not limited to, quaternary cationic surfactants conventionally used in the art. For example, quaternary cationic surfactants represented by the following formula Can be active:
