Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic characterized by being substantially free of water, and more particularly to a hair cosmetic which does not break a set hairstyle when used on hair. Without causing stickiness or weight,
The present invention relates to a composition that imparts moderate cohesion, good sliding, and luster.

[0002]

2. Description of the Related Art Various hair cosmetics have been developed to prevent entanglement of hair, to improve cohesion, and to give appropriate luster.
Cream, gel, solid, etc., or mist,
Various forms such as mousse and spray have been proposed. Prescription components include various oils, silicone derivatives,
An activator and the like were appropriately compounded.

[0003]

However, the composition in which water is blended in the prescription component has a drawback that, when used at the end of styling, the hair gets wet and the set hairstyle is destroyed. The combination of the oil agent and the surfactant may cause stickiness and weight depending on the selection of the type and amount, and when used at the end of styling, the set hairstyle may be broken. Also,
When a silicone derivative was used, stiffness and difficulty in washing hair were sometimes caused. Therefore, there has been a demand for development of a hair cosmetic which prevents the entanglement of hair, improves the unity, and imparts an appropriate luster while maintaining the set hairstyle.

[0004]

[Means for Solving the Problems] In view of such circumstances,
The present inventor has conducted intensive studies to overcome the above-mentioned drawbacks, and as a result, contains a specific amount of higher alcohol, ester oil and / or triglyceride oil, and lower alcohol, and is substantially free of water. Finds that hair cosmetics that do not break the set hairstyle when used on the hair, and give moderate cohesion, good sliding, and luster without causing stickiness or weight. Thus, the present invention has been completed.

That is, the present invention provides the following components (A) to
(C); (A) higher alcohol 0.1 to 5% by weight (B) ester oil and / or triglyceride oil 20
(C) 35 to 79.9% by weight of a lower alcohol, and is substantially free of water. Further, the following components (A) to
(C); (A) higher alcohol 0.1 to 5% by weight (B) ester oil and / or triglyceride oil 20
(C) 35 to 79.9% by weight of lower alcohol and containing a propellant in addition to a stock solution substantially free of water, wherein the mixing weight ratio of the stock solution and the propellant is , Stock solution: propellant = 50:50 to 10:90. Hereinafter, the present invention will be described in more detail.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The higher alcohol of the component (A) used in the present invention enhances the treatment effect by using it in combination with the ester oil and / or triglyceride oil of the component (B) as a treatment aid, and also enhances the hair. It has the function of imparting lubricity to the surface. The higher alcohol of the component (A) used in the present invention is not particularly limited as long as it is a higher alcohol that can be usually used for cosmetics, but preferably has 14 to 22 carbon atoms.
Examples include myristyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, oleyl alcohol, and the like. Of these, cetyl alcohol, stearyl alcohol, and behenyl alcohol are particularly preferred.

In the present invention, the higher alcohol as the component (A) can be used alone or in combination of two or more, but the amount of the higher alcohol is 0.1 to 5% by weight (hereinafter simply referred to as “%”). And more preferably 0.5 to 2.
5%. If the amount is less than 0.1%, the treatment effect and the lubricity of the hair cannot be obtained satisfactorily. If the amount exceeds 5%, the stability of the composition may be impaired.

The component (B) ester oil and / or triglyceride oil have excellent affinity to hair and effect of imparting conditioning property, and are smooth and supple to hair.
It works to give a sense of unity and is effective as a treatment effect imparting agent. The ester oil and / or triglyceride oil of the component (B) used in the present invention is not particularly limited as long as it is generally used in cosmetics and the like and can impart a treatment effect to hair. Ester oils such as isopropyl myristate, octyl palmitate, cetyl 2-ethylhexanoate, cetyl palmitate and propylene glycol dicaprate, and triglyceride oils such as glyceryl tri-2-ethylhexanoate and glyceryl tricaprate.

In the present invention, the ester oil and / or triglyceride oil (B) can be used alone or in combination of two or more.
-60%, more preferably 30-55%.
If less than 20%, the treatment effect cannot be obtained satisfactorily.
Also, if the content is more than 60%, the oily feeling becomes strong,
It is difficult to obtain good quality such as stickiness and weight.

In the present invention, the lower alcohol of the component (C) is used as a solvent for the components (A) and (B). The lower alcohol of the component (C) used in the present invention includes aliphatic monoalcohols having 1 to 3 carbon atoms, and specific examples thereof include ethanol and isopropanol. Of these, ethanol is particularly preferred.

In the present invention, the lower alcohol of the component (C) can be used alone or in combination of two or more. The blending amount is 35 to 79.9%, more preferably 40 to 65%. %. If less than 35% (A)
Ingredients of the component and the component (B) increase, and stickiness and weight may occur, which may cause adverse effects on usability.
On the other hand, if the content is more than 79.9%, the treatment effect cannot be obtained satisfactorily, and a squeaky feeling due to lower alcohol may be felt.

In the hair cosmetic of the present invention, it is essential that the above-mentioned components are blended and that the cosmetic does not substantially contain water. The inclusion of water as a prescription component has the disadvantage that when used on the hair at the end of styling, the hair gets wet and the preset hairstyle breaks down.

[0013] In addition, the above-mentioned components (A) to (C) are blended in a specific amount, added to a stock solution containing substantially no water, and further mixed with a propellant in a specific weight ratio. You can get cosmetics. In this case, the hair can be used without soiling the hands, and an appropriate amount is easily applied to the hair, so that the usability is further simplified.

Examples of the propellant include liquefied petroleum gas, dimethyl ether and the like, and these can be appropriately selected and used. In the case of a spray type hair cosmetic, the mixture weight ratio of the stock solution and the propellant is 50:50.
10:90, more preferably 40: 60-2.
0:80. By mixing within this range, the stock solution can be sprayed in a good spray form.

Further, the hair cosmetic composition of the present invention may further comprise, in addition to the above essential components, an anionic, cationic, nonionic, amphoteric, in a quantitative and qualitative range according to the purpose, without impairing the effects of the present invention. , Various oils other than polyhydric alcohols, ester oils and / or triglyceride oils, silicone oils, silicone derivatives such as polyoxyalkylene-modified organopolysiloxanes, various polymers, conditioning agents, emollients, ultraviolet absorption Other ingredients commonly used in hair cosmetics, such as agents, fragrances, bactericides, preservatives, antioxidants, and hair care cosmetic ingredients, can be added.

The hair cosmetic of the present invention may be in the form of a liquid, gel, cream, etc., depending on the combination with other components and the mechanism of the container.
The present invention can be carried out in various forms, and can be filled in a conventional aerosol container in combination with an appropriate propellant. Specifically, hair lotion, hair liquid,
It is possible to use hair gel, pomade, hair mist, hair spray, hair mousse and the like.
