DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol-type hair treatment composition, and more particularly, to a spray from a nozzle of an aerosol container. Is a spray-foam type composition that disappears at a moderate speed and has good familiarity with the hair, and because the fineness of the foam is fine, it can be applied evenly and evenly to the hair, giving the hair smoothness and luster It relates to a hair treatment composition.

[0002]

2. Description of the Related Art A so-called spray foam, which is sprayed from a nozzle of an aerosol container and adheres in a foam when it reaches hair, can be applied directly to hair, so that hands are not stained, so that it is not applied. It has been used in hairdressing products and the like as an easy-to-use product form because it has features such as the location of the part to be applied and the injection amount are easy to control because the part becomes white and foamy.

On the other hand, various conditioning components such as cationic surfactants, cationic polymers, lanolin derivatives and the like are used as treatment agents for imparting smoothness and softness to hair, and higher alcohols and the like are used as treatment aids or system aids. As a spray foam type hair treatment agent, for example, a combination of a cationic surfactant, a higher alcohol, a lower alcohol and a specific propellant is used in JP-A-9-175953. Techniques are disclosed.

[0004]

However, the conventional spray-foam type hair treatment agent has a satisfactory effect of imparting smoothness to the hair because the foam disappears at an appropriate speed and the hair becomes familiar. Although,
In some cases, the texture of the foam was coarse, and it was difficult to apply the foam evenly and evenly. So, without impairing the effect of the conventional spray foam type hair treatment agent,
In addition, there has been a demand for the development of a spray foam type hair treatment agent which has a fine foam and can be uniformly applied to the hair.

Hereinafter, the present invention will be described in detail. The aerosol-type hair treatment composition of the present invention comprises a stock solution and a propellant, and will be described first from the stock solution. The sucrose fatty acid ester of HLB 8 to 19 of the component (A) used in the present invention is a hydrophilic nonionic surfactant. In the present invention, the oil-in-water emulsion composition can be used in combination with the component (B). Works as an emulsifier in the undiluted solution,
It also has the effect of improving the moisturizing property and lubricity of the hair and imparting flexibility, and also has the function of giving the hair smoothness and flexibility. The sucrose fatty acid ester of the component (A) in the present invention has an HLB of 8 to 11, and if it has a HLB of 11 to 15, emulsification is more favorable and more preferable. When the HLB is less than 8 or more than 19, it is difficult to obtain a good emulsion in combination with the component (B).

The sucrose fatty acid ester of the component (A) can be generally used for cosmetics and the like, and has an HLB of 8 to 19.
There is no particular limitation as long as the fatty acid is 14 to 22 carbon atoms, and stearic acid and palmitic acid are particularly preferred.

In the present invention, the sucrose fatty acid ester of the component (A) can be used alone or in combination of two or more. The sucrose fatty acid ester having an HLB of 8 to 19 is, for example, HLB And a sucrose fatty acid ester having an HLB of 8 or more, and a weighted average value of the HLB in the range of 8 to 19.

This includes cases where the number is in the range of 18. The compounding amount of the component (B) is 0.05 to 5 parts, more preferably 0.1 to 1 part, in 100 parts of the stock solution. If the amount is less than 0.05 part, the emulsification is not sufficient, and if the amount exceeds 5 parts, the foaming becomes excessive, causing poor injection, and the function as a spray foam may be impaired.

In the present invention, the lower alcohol of the component (C) acts in the direction of breaking the foam stabilized by the properties of the sucrose fatty acid ester, the nonionic surfactant, the oil of the component (D), and the like, It shows the function of moderately adjusting the speed of bubble disappearance. More specifically, it is possible to realize a good bubble elimination property in which all the bubbles are easily erased by a single brushing after spraying the hair. Examples of the lower alcohol of the component (C) used in the present invention include aliphatic monoalcohols having 1 to 3 carbon atoms, specifically, ethanol,
Isopropanol is exemplified. 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, and the compounding amount is 1 to 50 parts in 100 parts of the stock solution.
More preferably, it is 5 to 30 parts. If the amount is less than 1 part, the compatibility between the stock solution and the propellant decreases and the spraying state deteriorates, and the foam disappears smoothly, and the foam remains without disappearing by one brushing, and the familiarity to the hair tends to deteriorate. Can be
On the other hand, when the amount exceeds 50 parts, the function as a spray foam may be impaired, such as deterioration of foaming properties.

The oil component (D) used in the present invention comprises:
As a treatment agent or treatment aid, it works to enhance the effect of giving hair smoothness,
Further, by forming an emulsion with water of the component (E), the stability of the system is enhanced, and it also has an effect of improving the feel during use. The oil agent of the component (D) used in the present invention is not particularly limited as long as it is an oil agent that can be usually used for cosmetics. Specific examples thereof include hydrocarbon oils such as liquid paraffin, squalane, and squalene; isopropyl myristate; Ester oils such as octyl palmitate, cetyl 2-ethylhexanoate, and propylene glycol dicaprate;

Examples include higher alcohols such as myristyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, oleyl alcohol, cetostearyl alcohol, and batyl alcohol. Of these, higher alcohols and glycerin fatty acid esters are preferred. Particularly, higher alcohols having 14 to 22 carbon atoms are preferred, and myristyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, oleyl alcohol, cetostearyl alcohol, and batyl alcohol are particularly preferred.

In the present invention, the oil agent of the component (D) can be used alone or in combination of two or more.
The compounding amount is 0.1 to 30 parts, more preferably 1 to 20 parts, in 100 parts of the stock solution. If the amount is less than 0.1 part, the treatment effect cannot be obtained satisfactorily. If the amount exceeds 30 parts, the function as a spray foam may be impaired, for example, resulting in deterioration of the spray state or foaming property.

In the present invention, the water of the component (E) forms an emulsion with the components (A) to (D), and purified water or the like is usually used.

Next, the propellant will be described. The propellant used in the present invention is a mixture of dimethyl ether (hereinafter referred to as DME) of the component (A) or liquefied petroleum gas (hereinafter referred to as LPG) of the component (A). DME of component (A) is a general-purpose propellant in aerosol products, but in the present invention, it has high compatibility with other components and has a function of adjusting the spray state as a propellant. On the other hand, LPG of the component (a) is also a general-purpose propellant, which is usually separated and refined from natural gas or petroleum, and mainly contains propane, butane, and isobutane. In the present invention, LPG exhibits compatibility with lower alcohols, ethers and the like, and has a function of adjusting the foaming state as a propellant. LP used in the present invention
