DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-in-water type hair cosmetic of the type to be washed away after application, such as a hair rinse, a hair treatment, and a hair conditioner.

[0002]

2. Description of the Related Art Conventionally, hair rinsing, hair treatment, etc. have been proposed to improve hair defects such as shampooing, smoothness or deterioration of combability that occur after shampooing or styling. Hair cosmetics such as hair conditioners are used. Various types of such hair cosmetics are provided, for example, those containing a cationic surfactant as a main component, and those containing an oil component such as silicone oil or olive oil. Also, today, there is a demand for a hair cosmetic that promises a smooth, moist, and moist finish when finished after drying. However, when silicone oils and oils blended in conventional hair cosmetics are used alone or in combination, they are insufficient in terms of smoothness and moist feeling when finished after drying.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hair cosmetic having an excellent finish after drying.

[0004]

According to the present invention, there is provided an oil-in-water type hair cosmetic comprising the following components (A), (B), (C) and (D): A) One or more kinds of cationic surfactants 0.1 to 20% by weight (B) One or more kinds of higher alcohols 0.1 to 30% by weight (C) Water-swollen clay mineral (D) At 20 ° C One or more silicone oils having a kinematic viscosity of 10,000 centistokes or more are provided.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the oil-in-water type hair cosmetic of the present invention will be described in more detail. Examples of the cationic surfactant which is the component (A) of the oil-in-water hair cosmetic of the present invention include quaternary ammonium salts, which have at least one guanidino group as a cationic group in the molecule, and A compound having an activity or a salt thereof may be used alone or in combination of two or more. The cationic surfactant of the component (A) has an action of imparting softness and flexibility to hair.

The quaternary ammonium salts include those represented by the following general formula (1).

The quaternary ammonium salts represented by the general formula (1) impart appropriate hydrophobicity to hair cosmetics, improve affinity for hair, and impart appropriate water retention to hair. Has the effect of making hair soft and supple. Here, the carbon number of the alkyl group and the alkenyl group is in the range of 10 to 24, preferably 12 to 22. If the number of carbon atoms is less than 10, the effect of softening and suppleness of the hair may not be sufficiently exhibited. If the number of carbon atoms exceeds 24, the hair becomes stiff and hard, and the effect of softening the hair tends to decrease. Not preferred. Further, the anion constituting the quaternary ammonium salt of the general formula (1) is preferably, for example, a chloride ion, a methyl sulfate ion or an ethyl sulfate ion. Such anions impart appropriate hydrophobicity and water retention to hair cosmetics.

[0008] Specific examples of such quaternary ammonium salts include the following. Stearyltrimethylammonium chloride, cetostearyltrimethylammonium chloride, behenyltrimethylammonium chloride and the like.

The compounds having at least one or more guanidino groups in the molecule and having a surfactant activity include alkylguanidines such as hexadecylguanidine, octadecylguanidine and 2-octyldodecylguanidine, and oleylguanidine. Alkylene guanidine, 2-guanidinoethyl lauroamide, 4-
Alkylamidoguanidines such as guanidinobutyllauroamide, 3-guanidinopropyloctanoylamide, 2-guanidinoethylstearoylamide, and 6-guanidinohexylmyristoylamide; alkyleneamide guanidines such as 4-guanidinobutylolenoylamide guanidine; N-coconut oil Fatty acid acyl-L-arginine ethyl, N-coconut oil fatty acyl-L-arginine stearyl, N-lauroyl-L-arginine propyl,
Arginine derivatives such as N-2 ethylhexanoyl-L-arginine methyl, 1,8-diguanidinooctane,
Examples include diguanidine derivatives such as 1,18-diguanidinoolein.

Further, D-, L-, and D- used in the present invention.
D. Examples of L-basic amino acids include D-lysine, L-lysine, and D. lysine. L-lysine, D-arginine, L-arginine, L-arginine, D-histidine, L-histidine, D. L-histidine and the like.

A salt of a compound having a guanidino group and having a surfactant activity, or a salt of D-, L-, D. In order to form a salt of an L-basic amino acid, the acid may be neutralized with an acid. Examples of the acid include inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid and nitric acid, acetic acid, citric acid, tartaric acid, propionic acid, and the like. Lactic acid, salicylic acid, glycolic acid, succinic acid, malic acid,
Organic acids such as butyric acid and prolidone carboxylic acid are exemplified.

The content of the cationic surfactant (A) is 0.1 to 20% by weight, preferably 0.5 to 1% by weight.
The range is 0% by weight. If the content is less than 0.1% by weight, the effect of making the hair soft and supple cannot be obtained. On the other hand, if the content exceeds 20% by weight, the hair becomes sticky, which is not preferable.

The higher alcohol which is the component (B) of the oil-in-water type hair cosmetic of the present invention has a function of imparting softness and suppleness to hair. As the higher alcohol, one having 14 to 22 carbon atoms can be used, and examples thereof include cetyl alcohol, stearyl alcohol, cetostearyl alcohol, and behenyl alcohol. Among them, cetyl alcohol or cetostearyl alcohol is most preferably used for the oil-in-water hair cosmetic of the present invention.

The content of the higher alcohol as the component (B) is in the range of 0.1 to 30% by weight, preferably 0.5 to 15% by weight. If the content is less than 0.1% by weight, the effect of making the hair soft and supple cannot be obtained. On the other hand, if the content exceeds 30% by weight, the hair becomes sticky, and the cosmetic becomes hard and difficult to apply to the hair, which is not preferable.

The water-swelling clay mineral, which is the component (C) of the oil-in-water hair cosmetic of the present invention, improves the rinsing property of the hair cosmetic when rinsing, gives a rich feeling and is moist when finished. It is blended to give a certain luster and smoothness. Clay minerals also have the effect of protecting hair from damage from the outside world. Specifically, the following can be used as the clay mineral. Bentonite (Kunimine Kogyo Co., Ltd., Knipure G, Mizusawa Chemical Co., Ltd., Benclay SL), montmorillonite (Kunimine Kogyo Co., Ltd. Knipure F).

The compounding amount of the clay mineral of the component (C) is 0.1.
It is in the range of 1 to 5% by weight, preferably 0.5 to 3.0% by weight. If the content is less than 0.1% by weight, the effect is not exhibited, and if it exceeds 5.0% by weight, emulsification is hindered.

The silicone oil which is the component (D) of the oil-in-water type hair cosmetic of the present invention is used in hair cosmetics such as slimy feeling when applied, smoothness when rinsing and smoothness when finishing. It is blended to give a feeling.

Examples of the silicone oil (D) include those represented by the following general formula (3).

Embedded image [In the formula, R ⁷ represents a hydrogen atom, a lower alkyl group having 1 to 3 carbon atoms, or a phenyl group. R ⁸ represents a lower alkyl group having 1 to 3 carbon atoms or a hydroxyl group. Also, n is 900
The above is particularly desirable. ]

The silicone oil as the component (D) is used in an amount of preferably from 0.1 to 0.1% based on the total amount of the hair cosmetic.
It is 50% by weight, particularly preferably 0.1 to 20% by weight. When the amount is less than 0.1% by weight, it is difficult to impart a smooth feeling of use to the hair cosmetic. If it exceeds 50% by weight, the hair becomes sticky and tends to have a heavy finish.

The hair cosmetic composition of the present invention includes the above (A) to
In addition to the component (D), fatty acids, higher alcohols, emulsion stabilizers, cold stabilizers, thickeners, plant extracts, animal extracts, animal and plant metabolites, which are generally incorporated into hair cosmetics as required. , A protein derivative, a crude drug, a bactericide, an oil, a surfactant, a pH adjuster, an ultraviolet absorber, a pigment, a fragrance, and the like.
