Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to a hair conditioning composition, and more particularly, to imparting smoothness, softness, and moist feeling to hair during use and at the time of finishing after drying, and further, after a lapse of time. The present invention also relates to a hair conditioning composition in which the hair does not become hard, and the conditioning effect is excellent in durability.

[0002]

2. Description of the Related Art Conventionally, hair cosmetics for hair conditioning include a rinse-off type such as a rinse and the like, a hair lotion, a hair cream, a hair gel, a hair mist, an aerosol type hair mousse, a hair spray and the like. Some have been used, and both have been widely used to impart conditioning effects to hair.

[0003]

However, in the conventional hair conditioning hair cosmetics, while the hair is smooth and soft during use and at the time of finishing after drying, the hair becomes harder as time passes thereafter. And the conditioning effect was sometimes not sustained. Therefore, there has been a demand for the development of a hair conditioning hair cosmetic composition which is excellent in the durability of the conditioning effect such that the hair conditioning is performed the night before and the conditioning effect is sufficient the next day.

[0004]

Under these circumstances, the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that a combination of a cationic surfactant, a hydrogenated castor oil, an ester of a higher fatty acid and a silicone derivative is used. By blending, the hair has smoothness, softness and moist feeling both during use and at the time of finishing after drying, and furthermore, the hair is hard to be hardened even after a long time, and the conditioning effect is improved. The present inventors have found that a long-lasting hair conditioning composition can be obtained, and have completed the present invention.

That is, the present invention provides the following components (A) to
(C) A hair conditioning composition comprising: (A) a cationic surfactant; (B) an ester of hydrogenated castor oil and a higher fatty acid; and (C) a silicone derivative.

Hereinafter, the present invention will be described in detail. The cationic surfactant of the component (A) used in the present invention is a raw material used as a hair conditioning agent, and has a good affinity and absorptivity to hair, and works to impart smoothness and softness to hair. However, the effect tends to decrease over time. In the present invention, by using the components (B) and (C) described below in combination, the effect can be maintained and an excellent conditioning effect can be obtained. The cationic surfactant of the component (A) used in the present invention is not particularly limited as long as it is generally used as a conditioning agent in hair cosmetics and the like, but a mono-long-chain alkyl-type quaternary ammonium salt is used. And a quaternary ammonium salt of a di-long chain alkyl type or a quaternary ammonium salt of an ethylene oxide (EO) addition type. Specifically, stearyl trimethyl ammonium chloride, behenyl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, distearyl dimethyl ammonium chloride, dibehenyl dimethyl ammonium chloride, dicetyl dimethyl ammonium chloride, stearyl dimethyl benzyl ammonium chloride, dilauryl dimethyl ammonium chloride, Dipolyoxyethylene (15EO) coconut oil alkylmethyl ammonium chloride; dipolyoxyethylene (4EO) lauryl ether dimethyl ammonium; and the like. Of these, stearyl trimethyl ammonium chloride, behenyl trimethyl ammonium chloride, distearyl dimethyl ammonium chloride, Divehenyldimethylammonium chloride is particularly preferred.

In the present invention, the cationic surfactant (A) can be used singly or in combination of two or more, if necessary.
% By weight (hereinafter, simply referred to as% by weight), and more preferably 0.5% to 3% in order to obtain a higher effect of imparting smoothness and softness to hair and maintaining it.

[0008] The ester of the hardened castor oil and the higher fatty acid as the component (B) used in the present invention is an ester compound of the hardened castor oil and the higher fatty acid obtained by hydrogenating the castor oil. There are monoester, hydrogenated castor oil higher fatty acid diester and hydrogenated castor oil higher fatty acid triester. Specific examples include castor oil hardened with stearic acid, castor oil hardened with isostearic acid, castor oil hardened with triisostearic acid, and castor oil hardened with monohydroxystearic acid. In the present invention, the component (B) imparts a moist feeling to the hair and, in combination with the component (A) or the component (C) described below, can improve the durability of the conditioning effect of the hair. The component (B) of the present invention is not particularly limited as long as it is an ester of a higher fatty acid and a hardened castor oil, which can be generally used for cosmetics, and a monoester of a hardened castor oil and a higher fatty acid having 14 to 22 carbon atoms is preferable. Specifically, monostearic acid hydrogenated castor oil, monoisostearic acid hydrogenated castor oil, monohydroxystearic acid hydrogenated castor oil and the like are preferable.
Of these, monostearic acid-hardened castor oil is particularly preferred.

In the present invention, the hardened castor oil component (B) and the higher fatty acid ester may be used alone or in combination of two or more.
The content is preferably 1 to 5%, and more preferably 0.2 to 3% in order to obtain a higher effect of imparting a moist feeling to hair and maintaining it.

The silicone derivative (C) used in the present invention is usually used for the purpose of imparting gloss and smooth feel to hair. In the present invention, the silicone derivative has smooth feel and combability. In addition to the effect of imparting the goodness of the above, the persistence of the effect can be improved by the combined use with the above other essential components. The silicone derivative of the component (C) used in the present invention is not particularly limited as long as it is a silicone derivative having an effect of imparting smooth feel and good combability to hair, and silicone oil, high molecular weight silicone, silicone resin , Cyclic silicone, polyether-modified silicone, amino-modified silicone, alkyl-modified silicone, alkyl polyether co-modified silicone, cationized silicone, fluorine-modified silicone and the like.

In the present invention, the silicone derivative of the component (C) can be used alone or in combination of two or more, if necessary.
10% is preferable, and from 0.1 to 0.1% to obtain a higher effect of imparting smooth feel and combability to hair and maintaining it for a long time.
8% is more preferred.

As described above, in the present invention, by using the component (A), the component (B) and the component (C) in combination, the hair is given smoothness, softness and moist feeling, and is excellent in hair. In addition to the above, a conditioning effect can be obtained, but in addition, the hair is hardly hardened even after a lapse of time, and the durability of the conditioning effect is improved.

In the hair conditioning composition of the present invention, in addition to the above essential components, a viscosity modifier, an emulsifier, an emulsifying aid, a pH adjuster, and a pH adjuster may be used within a quantitative and qualitative range depending on the purpose.
