Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel, two-layer-separated, foam-generating aerosol-type transparent hair which is blended with two or more kinds of oils, has improved touch feeling, is visually beautiful, and has two layers. It concerns cosmetics.

[0002]

2. Description of the Related Art Conventionally, in order to impart a good feel to hair, it is necessary to replenish oil, particularly to damaged hair, and liquid oils such as silicone oil have been used. These oils are water, lower alcohols,
Since it is immiscible in an aqueous medium such as a mixture of water and a lower alcohol, it has been necessary to emulsify with a surfactant or the like to mix and contain them. However, the emulsified stock solution becomes cloudy, and it is difficult to obtain a transparent appearance even when filled in a transparent container. Also, when a surfactant is used more than necessary, the stability over time of the stock solution is improved, but stickiness is caused, and the finish is inferior, and when aerosolized, there is a disadvantage that the foam quality is deteriorated with time. is there.

[0003] The applicant of the present invention has previously disclosed a foam-forming aerosol-type hair cosmetic which imparts good finish properties and has excellent foam stability over time by dividing and filling a hair lubricity imparting component. (Japanese Unexamined Patent Publication No. 5-22183)
No. 2). However, in this hair cosmetic composition, when the hair lubricity-imparting component is, for example, two or more incompatible oils, it has been difficult to mix transparently without turbidity. Further, in order to maintain the transparent state, it is necessary to add a new surfactant necessary for uniform mixing. In this case, there is a problem that stickiness is produced and the finish is adversely affected.

[0004]

SUMMARY OF THE INVENTION The present invention provides a novel, two-layered, foam-generating aerosol composition which imparts an excellent feel to hair, especially damaged hair, and is also visually beautiful. An object of the present invention is to provide a transparent hair cosmetic.

[0005]

The present inventors have conducted various studies on transparent hair cosmetics. As a result, when filling a plurality of water-immiscible liquid oily components, these oily components were classified into two or more. And by filling these directly into the container,
The present inventors have found that two layers having a transparent appearance without forming any turbidity are formed without using components for mixing and dispersing and without emulsification, thereby completing the present invention.

That is, the present invention relates to an aerosol-type hair cosmetic composition obtained by filling an aerosol pressure-resistant container with a stock solution comprising a plurality of liquid oily components and an aqueous component and a propellant, wherein at least two or more of the oily components are used. The foam-forming aerosol-type transparent hair cosmetic is further characterized in that the container is directly filled with the classified oily component, aqueous component and propellant. The present invention also provides the foam-forming aerosol-type transparent hair cosmetic, wherein the aerosol pressure-resistant container is a transparent container.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The foam aerosol-type transparent hair cosmetic composition of the present invention comprises a plurality of liquid oily components and aqueous components (hereinafter referred to as an aqueous stock solution) in an aerosol pressure-resistant container as described above.
And a propellant, which is filled by a specific method. First, each component of the hair cosmetic of the present invention will be described.

The aqueous medium used for the aqueous stock solution in the hair cosmetic composition of the present invention includes, for example, water, lower alcohols, and mixtures of water and lower alcohols. The lower alcohols include, in particular, ethyl alcohol. It is suitable.

Next, the liquid oily component used as an essential component in the hair cosmetic of the present invention is insoluble in the aqueous medium and is a component that imparts an excellent touch to damaged hair. is there. As such,
In addition to silicone derivatives such as dimethylpolysiloxane and organically modified silicone oil, liquid paraffin, liquid isoparaffin, hydrocarbon compounds such as animal and plant squalane, and natural animal and vegetable oils such as olive oil and jojoba oil are exemplified. Among these, dimethylpolysiloxane is particularly preferred in terms of hair finish. In a transparent hair cosmetic, these liquid oily components are usually 0.1 to 50% by weight, preferably 0.5 to 40% by weight, based on the total amount of the hair cosmetic.
It is blended in the range of weight%. If the amount is less than 0.1% by weight, the desired effect is not sufficiently exhibited, and if it exceeds 50% by weight, stickiness is unavoidable.

[0010] The hair cosmetic composition of the present invention is characterized in that the aerosol pressure-resistant container is filled with the oily component, the aqueous stock solution and the like by the following method. That is, in the present invention, a plurality of liquid oil components such as the silicone derivative and other liquid oil components are charged separately from the aqueous stock solution. At this time, a plurality of liquid oily components such as a silicone derivative and other liquid oil components separated from the stock solution are divided into two or more, and they are mixed and dispersed by directly filling them into a pressure-resistant aerosol container. Need not be added, the finish such as stickiness is not impaired, and a layer having a transparent appearance without turbidity can be formed.

In the present invention, when a plurality of liquid oily components are divided into at least two or more, it is preferable to divide the plurality of liquid oily components into respective oily components. Several types of oily components may be appropriately combined and classified. In this case, it is preferable to combine oil components having good compatibility. For example, it is preferable to combine a high-viscosity dimethylpolysiloxane and a low-viscosity dimethylpolysiloxane without intentionally dividing them.

The type of the propellant used in the hair cosmetic of the present invention is not particularly limited, and any of those usually used in foam-forming hair cosmetics can be used. Specifically, liquefied petroleum gas or the like is used. The used amount of the propellant is usually in the range of 3.0 to 10.0 parts by weight per 100 parts by weight of the stock solution.

In the present invention, when each of the divided liquid oily components, the aqueous concentrate and the propellant is filled into an aerosol pressure-resistant container, the order of filling each of the water-immiscible liquid oil and the aqueous concentrate is particularly important. There is no limitation, and a predetermined container is filled in an arbitrary order, and thereafter, the propellant is filled.

The hair cosmetic composition of the present invention may further contain, in addition to the above-mentioned essential components, various additives commonly used in conventional hair cosmetic compositions, as long as the object of the present invention is not impaired.
