The agent may be, if necessary, compounded with a humectant, a blood circulation-accelerating agent, a cooling agent, an UV absorbent, a sterilizer, a perfume, etc. The agent can be applied as a shampoo, pre-shampoo, hairdressing cream remover, dandrull-removing agent, etc., in an O/W type emulsified transparent-semitransparent jelly.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hair treatment agent, and more particularly, the present invention relates to a hair treatment agent that stably contains a large amount of liquid oil and is used to treat polymers such as high viscosity silicone contained in hair products. The present invention relates to a hair treatment agent that exhibits an excellent cleaning effect on scum and poorly soluble aged oil and fat stains, and has an extremely pleasant feel.

[Problems to be solved by conventional techniques and inventions] Conventionally,
Shampoos are used to wash away dirt from the scalp and hair, to keep them clean, to normalize their physiological functions, to keep the scalp healthy, and to make the hair beautiful.

Shampoos contain anionic surfactants, amphoteric surfactants, and nonionic surfactants as the main active ingredients, but in recent years, excessive degreasing due to the increase in the number of shampoos, and friction during shampooing. In order to reduce irritation to the hair and scalp, the use of hypoallergenic cleansing surfactants and the addition of various conditioning agents such as polymers have made it possible to avoid excessive degreasing with shampoos as in the past. ing.

On the other hand, high viscosity silicone, moisture-resistant setting polymers, etc. are added to hair products such as setting agents to improve their functions, but these are difficult to clean with conventional shampoos. This, together with the above-mentioned limitation in shampoo degreasing ability, makes it difficult to remove and clean polymers, poorly soluble sebum, etc. from the scalp and hair.

If the removal of these components from the scalp and hair is insufficient, the hair may lose its dark color, have more split ends and breakage, become dry and dry, and become less slippery.
Various problems occur such as loss of elasticity, difficulty in tying the hairstyle, poor hairstyle, poor perm, tangles, and tendency to get caught.

Therefore, there has been a desire for a hair treatment agent that is gentle on the scalp and hair and that can easily remove high viscosity silicone and sebum stains that are difficult to clean with conventional shampoos.

[Means for solving problems]

Under these circumstances, the present inventors conducted intensive research and found that a hair treatment agent obtained by combining an aqueous component consisting of a surfactant, alcohol, and water with a liquid oil having a lower viscosity is effective against the scalp and scalp. The present invention was based on the discovery that it is gentle on the hair, can easily remove stains such as high viscosity silicone that are difficult to clean with conventional shampoos, has a good feeling of use, and has excellent stability. completed.

That is, the present invention comprises the following components (a) to (d) (a) surfactant, etc.) alcohols (c) water (d) liquid oil, and an aqueous component consisting of (a) to (c). The present invention provides a hair treatment agent characterized by having a viscosity ratio of 1 or more between hair and oil components.

Examples include cationic surfactants such as alkylisoquinolinium salts; amphoteric surfactants such as imidacilline type, amide amino acid salt, alkylbetaine type, and alkylsulfobetaine type.

These (a) components can be used alone or in combination of two or more, and are 0.05 to 15% by weight (hereinafter simply expressed as "%") in the total composition, particularly 0.1 to 5% by weight. % is preferable.

Examples of the alcohol component (b) include monoalcohols such as ethanol, glycerin, ethylene glycol, diethylene glycol, triethylene glycol, hexanediol, butylene glycol, heptanediol, propylene glycol, sorbitol,
Examples include polyols such as maltitol and polyethylene glyfur.

Among these, ethanol, glycerin, propylene glycol, butylene glycol, sorbitol, polyethylene glycol and the like are particularly preferred.

These alcohols can be used alone or in combination of two or more, and are 0.5 to 40% in the total composition, especially 2 to 40%.
It is preferable to mix 30%.

Component (c) water is 0.1 to 25% in the total composition, especially 1
It is preferable to mix 15% to 15%.

The liquid oil of component (d) is not particularly limited as long as it is a liquid oil at 25°C, and examples include volatile cyclic silicones such as four- and five-membered rings, 100 cs or less (7) dimethylpolysiloxane, Examples include hydrocarbons such as methylphenylpolysiloxane of 100 cs or less, squalane, liquid paraffin, and isoparaffin, branched fatty acids, higher fatty acid esters, benzoic acid esters, triglycerides, diglycerides, and rosin derivatives. Among these, especially cyclic silicone, dimethylpolysiloxane and methylphenylpolysiloxane of 20cs or less, 20cs

These liquid oils can be used alone or in combination of two or more, and contain 20 to 98%, especially 50 to 98%, of the total composition.
% is preferable.

Furthermore, the hair treatment agent of the present invention contains, in addition to the above-mentioned essential ingredients,
To the extent that the effects of the present invention are not impaired, ingredients used in ordinary cosmetics, such as moisturizers, blood circulation promoters, cooling agents, ultraviolet absorbing or reflecting agents, antiperspirants, bactericidal agents, skin activators,
Anti-aging agents, fragrances, colorants, etc. can be added.

The hair treatment agent of the present invention can be produced by a conventional method, but especially by mixing and stirring the aqueous components (a) to (c) to make them uniform, and then slowly adding the oil component and stirring. Preferably, it is manufactured. This method is usually carried out at room temperature, but may be carried out with heating if, for example, the raw materials do not melt at room temperature.

In the present invention, the oil component is stably retained in the O/W type emulsion. In addition, the viscosity ratio of the aqueous component consisting of components (a) to (c) and the oil component needs to be 1 or more. If it is less than 1, it is not possible to stably blend a large amount of the oil component, oil floating or separation occurs, which not only causes problems in appearance but also does not provide sufficient performance, which is not preferable.

The hair treatment agent of the present invention is die IJ-like, that is, -phase transparent or translucent, and has a 1.0.0OOO
It is obtained as a gel-like material having a viscosity of Cs or higher, and can be applied as a shampoo, pre-shampoo, hair makeup remover, dandruff remover, etc.

[Action and effect]

The hair treatment agent of the present invention is a transparent to semi-transparent sherry-like emulsion of ○/W type that stably contains a large amount of liquid oil. When this is applied to the scalp or hair and pine surge is performed, the oil agent is absorbed into the scalp. The oil agent quickly spreads over the hair, and this oil directly dissolves the oily dirt accumulated on the scalp and hair or removes it from the hair. Furthermore, when rinsed with a large amount of water, these dirt-containing oils self-emulsify due to the action of surfactants and are washed away cleanly. Oil stains can be easily removed. Also,
It is gentle on the scalp and hair, and has an extremely good feel when used.

In addition, since the hair treatment agent of the present invention uses a large amount of liquid oil, it can be used as a conditioning agent in itself, and oil-soluble active ingredients, which were conventionally difficult to use, can be easily applied to the scalp and hair. It is also useful for applying to hair and the like.
