Description

Hair conditioning composition

The present invention relates to a hair conditioning composition, and more particularly, to a hair conditioning composition having excellent hair conditioning effect after drying while being less slippery when rinsing.

Recently, as the standard of living has improved, interest in beauty is increasing, and hair beauty is an important part. According to this trend, various hair cosmetic products such as dyeing products and permanent products have been researched and commercialized.

However, frequent dyeing and perm are easy to damage the hair, and thus the damaged hair is not glossy, fluffy and difficult to prepare. In addition, even in the case of healthy hair, only shampoo is used to remove oil from the hair due to excessive washing, resulting in lack of gloss and difficulty in maintaining calm hair due to static electricity.

Therefore, in order to overcome this, an emulsion conditioner composed of a hair conditioning material such as higher alcohol, cationic surfactant, water, and silicone is generally used. However, high-alcohol conditioners are not suitable for those with thin hair or sensitive scalp because they leave excess oil on the hair and adversely affect the scalp. To this end, high-alcohol-free or low-rinse rinses are available on the market but are less effective in hair conditioning.

For example, U.S. Patent Application Publication No. 2003/0216267 discloses a transparent conditioner, but does not include higher alcohol, so that the effect of the overall conditioner is lowered. In addition, U.S. Patent No. 6,365,142 discloses an emulsification system and a fatty alcohol and a silicone conditioning agent that neutralize tertiary alkylamine, but a rich feeling and excellent conditioning effect are expected in use, but there are many drawbacks when rinsing.

Therefore, the problem to be solved by the present invention is to provide a hair conditioning composition having a lower content of higher alcohol than the conventional, less slippery during rinsing, but does not fall overall feeling during application and after drying.

In order to solve the above problems, the hair conditioning composition of the present invention is a polyacrylate-1 crosspolymer (Polyacrylate-1 Crosspolymer) cationic carbomer; It is a glyceryloxyhydroxypropyl alkyldimonium chloride cationic surfactant represented by the following formula (1),

In Formula 1, R is a C _12-18 linear or branched alkyl group, alkenyl group or a combination 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 of a specific structure, if necessary.

The hair conditioning composition of the present invention is excellent in the conditioning effect after wetting and after drying, while being less slippery when rinsing.

Hereinafter, the present invention will be described in detail. The terms or words used in this specification and claims are not to be construed as limiting in their usual or dictionary meanings, and the inventors may appropriately define the concept of terms in order to best explain their invention in the best way possible. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention based on the principle that the present invention.

The dispersion stability is also excellent.

The content of the polyacrylate-1 crosspolymer according to the present invention may be appropriately determined as necessary, and may be, for example, 0.1 to 5 wt% 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 thickening effect may be insignificant. If the content of the polymer is more than 5% by weight, the viscosity may be too high, thereby reducing compatibility.

In order to improve the viscosity with the polyacrylate-1 crosspolymer according to the present invention, pH conditions should be adjusted. Viscosity appears under acidic conditions, and thereafter, the viscosity does not decrease even when the pH is increased. Therefore, the viscosity required at acidic conditions of pH 3-4 is generally introduced and then adjusted to an appropriate pH with a basic substance.

In order to evaluate the smoothness of the hair conditioning composition prepared in Examples and Comparative Examples, the coefficient of friction of the hair after wet and dry was measured. The hair used was a European dark brown hair obtained from De Meo Brothers, USA, made of a 18 cm long, 1.5 g tare. The hair tareres were washed with a conventional shampoo, treated with 1 g of the product of Examples and Comparative Examples for 1 minute, rinsed in running water for 30 seconds, squeezed out, and the coefficient of friction at the time of wetness was measured. After drying for 12 hours at 25 ° C. and 50% constant temperature and humidity conditions, the coefficient of friction of dry hair was measured. The instrument used was a MTT-160 tensile strength tester obtained from Dia-Stron, UK, the friction speed was 300 mm / min, the vertical load was 100g. The friction coefficient was obtained by the following Equation 1, and the smaller the friction coefficient, the smoother. The experimental results are shown in Table 5.
