Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition, and more particularly to a hair cosmetic composition capable of continuously imparting flexibility and smoothness to treated hair.

[0002]

2. Description of the Related Art Hair treatment agents containing a reducing agent have been known. For example, the first permanent agent usually contains a reducing agent in order to swell and soften the hair. Then, the hair is oxidatively fixed by the second agent containing the oxidant and exerts a permanent effect.

Further, a hair dye containing a reducing agent as an essential component is known in order to obtain a hair dye having a mild action and an excellent dyeability (Japanese Patent Laid-Open No. 3-72144).
On the other hand, a hair treatment agent containing a silicone derivative is known. Conventionally, a rinsing agent or treatment agent containing a quaternary ammonium salt has been used to prevent damage to the hair by washing the hair with shampoo, drying it with a drier, and perming treatment, but it makes the hair softer. The effect was slight, and only a temporary effect could be expected.

Therefore, it is known that when a keratin substance decomposing derivative and a silicone derivative are mixed in a hair treatment agent, the protein is supplemented by the keratin substance decomposing derivative and the elution is prevented by the silicone derivative (JP-A-57). -130910). Further, it is known that the rinsing effect is improved by using a silicone derivative and polyethylene glycol together with a quaternary ammonium salt (JP-A-56-99407).

Further, a hair dye containing a silicone derivative for enhancing the hair dyeing effect (JP-A-57-192310).
No.), a shampoo containing a silicon derivative for improving the conditioning effect (JP-A-58-7479).
No. 8), a hair conditioner containing a silicone derivative together with other essential components to prevent redeposition after washing the hair (Japanese Patent Laid-Open No. 61-6), and other hair treatment agents containing many silicone derivatives are disclosed. ..

[0006]

By the way, when the hair loses its flexibility and smoothness, it loses its aesthetic appearance and worsens combing, which causes breakage and split ends. Therefore, effectively imparting flexibility and smoothness has been a serious issue for hair cosmetics, and various hair cosmetics have been developed.

However, although some of the above-mentioned effects are obtained immediately after use, there is a problem in that the effect is not long-lasting and the effects are diminished over time. The present invention has been made from such a point of view, and it is an object of the present invention to effectively provide the flexibility and smoothness of the hair after use and to provide a hair cosmetic composition having excellent durability of these effects. And

[0008]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventor has found that a hair cosmetic composition includes a first agent containing a reducing agent and a second agent containing an epoxy-modified silicone. And then using these to treat hair sequentially,
The present inventors have found that it is possible to continuously impart flexibility and smoothness to hair, and have reached the present invention.

That is, the present invention is a hair cosmetic composition comprising a first agent containing a reducing agent and a second agent containing an epoxy-modified silicone. Furthermore, the present invention includes a method for treating hair, which comprises treating the hair with a first agent containing a reducing agent, and then treating the hair with a second agent containing an epoxy-modified silicone, and a reducing agent. Provided are a method for treating hair, which comprises mixing a first agent and a second agent containing an epoxy-modified silicone, and treating the hair with this mixture, and a hair cosmetic used in these methods.

As described above, the hair cosmetic composition of the present invention is a combination of the hair cosmetic compositions comprising the first agent and the second agent, each of which can be used alone. In addition, when treating the hair by mixing the first part and the second part before use, they are mixed to form a single cosmetic.

The present invention will be described in detail below.

<1> First Agent The first agent of the present invention is a hair cosmetic containing a reducing agent. Examples of the reducing agent used in the present invention include thioglycolic acid or a salt thereof (ammonium thioglycolate, sodium thioglycolate, potassium thioglycolate, thioglycolic acid monoethanolamine, thioglycolic acid diethanolamine, thioglycolic acid triethanol. Amines, etc.), mercaptan compounds such as thioglycerin, dithioglycerin, thioglycol, thioglycolic acid ethanolamide, N-acetyl-cysteine, or salts thereof, cysteine compounds such as cysteine hydrochloride, thioacetamide, sodium sulfite, potassium sulfite, etc. Bisulfite, sodium bisulfite, bisulfite such as potassium bisulfite, ascorbic acid or its derivatives (ascorbyl stearate, ascorbyl palmitate, dipalmitin Ascorbyl etc.), glucose, a sugar or derivatives thereof such as sorbic acid, citric acid, organic acids such as lactic acid, and other, salicylaldehyde, thiosalicylic acid, sodium hypophosphite, and the like. Among these, thioglycolic acid or a salt thereof, a cysteine compound, and sodium sulfite are particularly preferable.

The first agent of the present invention is a hair cosmetic composition containing one or more of the above reducing agents, and includes shampoo, conditioner, hair conditioner, treatment,
Blow lotion, hair cream, styling gel, hair mousse, split hair coat, hair liquid, hair tonic, hair restorer, hair restorer, etc. for treating hair, regardless of aqueous, oily, gel-like dosage forms .. Also,
As these other components, those usually used for hair cosmetics may be used, and they may be produced according to the usual method for producing hair cosmetics.

The reducing agent is 0.01 with respect to the total amount of the first agent.
-10%, preferably 0.5-5%. If the blending amount is less than this range, a sufficient effect of imparting flexibility and smoothness to hair cannot be expected. Further, if the amount is more than this range, the reducing action is too strong and the hair is damaged.

<2> Second Agent The second agent of the present invention is a hair cosmetic composition containing an epoxy-modified silicone. The epoxy-modified silicone is represented by the following general formula (Formula 1).

[0016]

[Chemical 1]

In the formula, R is an alkylene group having 1 to 3 carbon atoms,
x is 1 to 500, preferably 1 to 250, and y is 1 to
It represents a number of 50, preferably 1 to 30. The second agent of the present invention is a hair cosmetic composition containing one or more kinds of epoxy-modified silicone, which is a rinse, hair conditioner, treatment, blow lotion, hair cream, styling gel, hair mousse, split hair coat, hair liquid, Hair tonics, hair nourishing agents, hair restorers, and the like for treating hair, regardless of their aqueous, oily, gel-like dosage forms, etc., may be used as long as they are used after the first agent is used.

The second agent may be the same kind of cosmetic material as the first agent, and the first agent and the second agent may be mixed and used at the time of use. Epoxy-modified silicone is
Preferably 0.1 to 30% is blended. If the blending amount is less than this range, the effect of imparting flexibility and smoothness to hair is lacking in sustainability, and if the blending amount is more than this range, oiliness is felt and the feeling of use deteriorates, so it is preferable to blend in the above range.

Similar to the first agent, the second agent is not particularly limited in other components and manufacturing method. The epoxy-modified silicone may be dissolved in cyclic silicone or the like and added to the preparation, or may be emulsified with a surfactant, and may be appropriately selected depending on the dosage form.

<3> Hair Treatment Method of the Present Invention The hair treatment method of the present invention comprises a step of treating hair with the first agent and a step of subsequently treating hair with a second agent. The combination of the first agent and the second agent is arbitrary, and the second agent may be used after the first agent. For example, a combination of shampoo as the first agent, rinse as the second agent, blow lotion as the first agent, and split ends coat as the second agent can be mentioned.

The first agent and the second agent may be mixed before use. For example, the first agent and the second agent, which are hair cosmetics of the same kind, are mixed with a palm or the like, and the hair is treated with the mixture. In particular, in cosmetics such as hair cream and hair mousse that are held on the hair for a long time, the effects can be obtained even if the order of use of the first agent and the second agent is different.

It is more preferable that a heat treatment such as a drier or a blow is applied at the time of use.

[0023]

When the hair is treated with the first agent of the hair cosmetic composition of the present invention and then treated with the second agent, or when the hair is treated with a mixture of the first agent and the second agent having the same purpose, each makeup is treated. In addition to the action of the essence, it is possible to continuously impart softness and smoothness to the hair.
