Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a hair treatment and a method for setting hair using the same.

[0002]

2. Description of the Related Art Hair treatment mainly comprises a cationic surfactant, a higher alcohol and an oil,
It is mainly used for the purpose of imparting flexibility to hair and suitably changing the feel and appearance of hair.

[0003]

However, in the conventional hair treatment, it has not been possible to impart curl to hair or to impart straightness to hair.

Accordingly, the present invention solves the above-mentioned problems in the prior art, and without damaging the hair.
An object of the present invention is to provide a hair treatment capable of imparting curl to hair and imparting straightness to hair.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, a cationic surfactant, a higher alcohol and an oil component are used as main components, and a reducing agent is used in an amount of 2 to 11%. % By weight and a pH of 7 to
The inventors have found that a hair treatment adjusted to 12 can solve the above problems, and have completed the present invention.

That is, the hair treatment is applied to the hair, left for 3 to 30 minutes, washed with water, and dried to leave a part of the water.
When wound around a rod part of a curling hair iron at 20 ° C. and heat-treated, the hair can be provided with curling properties, and the dried hair can be heated to a temperature of 60 to 220 ° C.
When pressed under heating while being sandwiched between the plate portions of the straightening hair iron, straightness can be imparted to the hair, and the above problem can be solved.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The point that the hair treatment of the present invention is particularly different from the conventional hair treatment is that the hair treatment contains a reducing agent.
For example, thioglycolates such as thioglycolic acid and ammonium thioglycolate, cysteinates such as cysteine and cysteine hydrochloride, cysteine derivatives such as N-acetylcysteine and cysteamine, thioglyceryl alkyl ether, mercaptoalkylamide, sulfite , Bisulfite and the like can be used.

The above reducing agents can be used alone or in combination of two or more. The content of the reducing agent in the hair treatment must be 2 to 11% by weight, and especially 4 to 11% by weight. Preferably it is 11% by weight. Content of reducing agent in hair treatment is 2
When the amount is less than 10% by weight, curling or straightness cannot be imparted to the hair, and when the content of the reducing agent in the hair treatment is more than 11% by weight, the hair is damaged, and The uniform slip (slip) feeling is reduced.

Further, the hair treatment of the present invention has a pH
Is required to be 7 to 12, and for this purpose, an alkali agent is added. Examples of such an alkali agent include ammonium bicarbonate, aqueous ammonia, monoethanolamine, diethanolamine, triethanolamine, and potassium hydroxide. , Sodium hydroxide, sodium borate, sodium carbonate, and the like.

[0010] In the present invention, p of hair treatment
It is necessary that H is 7 to 12 because if the pH of the hair treatment is lower than 7, it is impossible to impart curl or straightness to the hair, and if the pH of the hair treatment is higher than 12. This is because the hair is damaged, and the gloss and uniform slipperiness of the hair are reduced. And it is especially preferable that pH of this hair treatment is 8-11.

[0011] The hair treatment of the present invention contains a reducing agent and a pH of 7 to 12, as described above, except that a cationic surfactant, a higher alcohol and an oil component are used in the same manner as a normal hair treatment. Is constituted as a main component.

Examples of the cationic surfactant include, for example, stearyltrimethylammonium chloride, cetyltrimethylammonium chloride, stearyltrimethylammonium bromide, cetyltrimethylammonium bromide, behenyltrimethylammonium chloride, lauryltrimethylammonium chloride, lauryltrimethyl bromide. Ammonium, dibehenyl dimethyl ammonium chloride, dicetyl dimethyl ammonium chloride, distearyl dimethyl ammonium chloride, dicocoyl dimethyl ammonium chloride,
Examples include myristyldimethylbenzylammonium chloride, stearyldimethylbenzylammonium chloride, lanolin fatty acid amidopropylethyldimethylammonium ethyl sulfate, and dimethylaminopropylamide stearate.

In the present invention, the content of the cationic surfactant in the hair treatment is from 0.1 to 15
% By weight, especially 1 to 10% by weight. When the content of the cationic surfactant in the hair treatment is less than 0.1% by weight, the hair may not be able to be imparted with flexibility and good finger passing property. If the content in the hair treatment is more than 15% by weight, the wash-off will be too large, and the necessary components will also be washed away, which may reduce the sustainability of the effect.

As the higher alcohol, for example,
Cetanol (cetyl alcohol), stearyl alcohol, oleyl alcohol, octyldodecanol, chimyl alcohol, isostearyl alcohol, cholesterol, sitosterol, serachyl alcohol, decyltetradecanol, phytosterol, hexyldecanol, lauryl alcohol, myristyl alcohol, cetostearyl alcohol , Behenyl alcohol, batyl alcohol and the like.

[0015] The content of these higher alcohols in the hair treatment is 0.5 to 20% by weight, especially 1 to 20% by weight.
~ 15% by weight is preferred. When the content of the higher alcohol in the hair treatment is less than 0.5% by weight,
There is a risk that the hair may not be able to impart flexibility and good finger passing properties. If the content of the higher alcohol in the hair treatment is more than 15% by weight, the amount of adsorption to the hair becomes too large, Accordingly, the hair may be rough or rough.

Examples of the oil component include vegetable oils such as avocado oil and shea butter, animal oils such as mink oil and egg yolk oil, animal waxes such as sperm whale oil, beeswax and lanolin, and vegetable oils such as jojoba oil. Wax, mineral solid wax such as montan wax, paraffin, polyethylene,
Hydrocarbons such as petrolatum, higher fatty acids such as oleic acid, esters such as isopropyl myristate, fluorine oils such as perfluoropolyether, dimethylpolysiloxane, cyclic siloxane, methylphenylpolysiloxane, methylpolysiloxane, and polyether-modified silicone And silicone oil such as amino-modified silicone.

The content of the oil in the hair treatment is 0.01 to 15% by weight, particularly 0.05 to 10% by weight.
% By weight is preferred. When the content of the oil in the hair treatment is less than 0.01% by weight, the hair may not be able to be imparted with flexibility and good finger passing property, and the content of the oil in the hair treatment may be 15%. When the amount is more than the weight%, the amount of adsorption to the hair becomes too large, which may give the hair stickiness.

The hair treatment of the present invention is prepared by dissolving or dispersing the above components in water or a water-based medium. At that time, if necessary, for example, a reaction modifier such as dithioglycolic acid or a salt thereof, an anionic surfactant, various surfactants such as a nonionic surfactant, carboxymethylcellulose or a salt thereof, pullulan or Derivatives thereof, carrageenan, xanthan gum, thickeners such as various alkylolamides, humectants such as propylene glycol, 1,3-butylene glycol, glycerin, collagen,
Hydrolysates of proteins derived from animals and plants, such as keratin, silk, soybean protein, and wheat protein, and derivatives thereof, preservatives, stabilizers, anti-inflammatory agents, coloring agents, chelating agents, flavors, and the like can be appropriately contained.
