Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an aerosol type first agent composition for permanent wave. More specifically, the size of the formed wave is almost uniform throughout the hair, and it has excellent toughness and wave durability.
The present invention relates to an aerosol-type first agent composition for permanent wave, which causes less damage to the scalp and can be easily treated.

[0002]

2. Description of the Related Art A permanent waving agent is for forming a wave on hair for a long period of time and comprises a first agent containing a reducing agent as a main agent and a second agent containing an oxidizing agent as a main agent. The mechanism of forming a wave on the hair by such a permanent waving agent is to fix the hair on a rod or the like to curl it, and reduce the disulfide bond of cystine contained in the keratin protein in the hair with a reducing agent by the first agent. By doing so, a mercapto group is generated, and the mercapto group is oxidized with an oxidizing agent by the second agent to generate a new disulfide bond in the hair to immobilize the wave.

Usually, thioglycolate and cysteine are used as the reducing agent, and bromate, hydrogen peroxide and the like are used as the oxidizing agent.
To promote these functions, the first agent contains an alkaline agent, and the second agent contains an acid to neutralize the alkali of the first agent. Further, a surfactant is mixed for the purpose of penetrating the medicinal solution between the hairs, and an additive is mixed for the purpose of protecting the hair from the chemical influence of the medicinal solution.

However, if the blending amount of these surfactants and additives is large, the function of the drug solution is hindered, while if the blending amount is small, the permeability of the drug solution is poor and a non-uniform wave is formed.

Further, in the conventional permanent waving agents, it is not taken into consideration that the hair quality of the hair is different between the hair tip and the root, and the hair tip has a newly formed part of the root that physically changes with time. Also, while the degree of damage due to chemical damage is extremely small, the degree of damage is large. In addition, when the first agent is uniformly applied to the hair in such a state, the wave is strongly applied to the tip of the hair and is loosely applied to the root, so that an uneven wave is formed. .. In addition, there is a problem in that the tip of the hair is more strongly affected by the first agent and the degree of damage is greater.

Furthermore, in the operation of winding the rod from the tip of the hair,
Since the diameter of the rod becomes thicker toward the root, uneven waves are likely to be formed. The formation of such a non-uniform wave may interfere with the formation of a favorable hairstyle and regular hair styling, and the hair care may be complicated, leading to a reduction in wave durability.

[0007] The first permanent wave for the conventional
The agent is easy to disperse and often adheres to the operator's finger, so the operation is not easy and may damage the operator's finger.Moreover, a highly volatile solvent is used for storage. In some cases, the solvent is volatilized, and the reducing agent as the main component is oxidized by an enzyme in the air to deteriorate the quality.

Incidentally, for example, Japanese Patent Publication No. 38-629
No. 8, JP-A-54-73135, JP-A-56-63914, and JP-A-51-22832 disclose various aerosol type perm agent compositions. None of the products could sufficiently solve the above problems.

[0009]

Therefore, the present inventors have found that
As a result of earnest studies in view of the above-mentioned conventional techniques, a uniform permanent wave is formed on the entire hair, and the degree of damage to the hair is reduced, and the hair is less likely to scatter and easily penetrates into the hair to be applied to the practitioner. Finally, the inventors have found a first-agent composition for permanent wave, which is capable of eliminating the rough skin of the fingers, has a good storage condition and has a small deterioration in quality, and has completed the present invention.

[0010]

That is, the present invention relates to an aerosol type permanent wave first agent composition containing a solvent and a propellant comprising a liquefied gas and / or a compressed gas.

[0011]

ACTIONS AND EXAMPLES The first agent composition for an aerosol type permanent wave of the present invention contains a solvent and a propellant composed of a liquefied gas and / or a compressed gas as described above.

Aliphatic polyhydric alcohols such as triethylene glycol, polyethylene glycol, dipropylene glycol, butanediol, hexylene glycol, glycerin, N
-Pyrrolidones such as methylpyrrolidone can be used alone or in admixture of two or more, and among them, ethanol, benzyl alcohol, orange oil, from the viewpoint of permeability to the hair surface, Diethanolamine carbonate, N-methylpyrrolidone and isoparaffin hydrocarbons are preferably used.

The content of the solvent is preferably 0.5 to 30% (% by weight, the same applies hereinafter), particularly 10 to 20% in the first agent composition for an aerosol type permanent wave. If the content of such solvent is less than 0.5%,
If the effect is not satisfactory, and if it exceeds 30%, the cost becomes high and problems such as a bad odor tend to occur.

In the present invention, the propellant comprises liquefied gas and / or compressed gas, and such liquefied gas is
Examples include dimethyl ether, liquefied petroleum gas, fluorocarbons, and the like.
Examples thereof include CO ₂ gas, N ₂ gas, N ₂ O gas and the like. These may be used alone or in combination of two or more, but from the viewpoint of improving the jettability of the composition obtained among them and improving the miscibility of the water-soluble main agent and the solvent described later, Dimethyl ether is particularly preferably used.

The content of the propellant is preferably 1 to 30%, more preferably 5 to 20% in the first type composition for aerosol type permanent wave. When the content of the propellant is less than 1%, the spray pressure becomes low, the foam-breaking property is deteriorated, the permeability to the hair becomes small, and 30%.
If it exceeds, the jetting pressure becomes high and the liquid is scattered, so that an appropriate amount of the composition tends not to adhere to the hair.

In the first agent for aerosol type permanent wave of the present invention, a conventional reducing agent which has been conventionally used can be used as the reducing agent. Examples of such reducing agents include thioglycolic acid, ammonium thioglycolate, thioglycolic acid such as thioglycolic acid monoethanolamine or a salt thereof; or a thioglycolic acid-based reducing agent consisting of glycerin monothioglycolate, L -Cysteine, L-cysteine hydrochloride, D
Examples of the present invention include L-cysteine, cysteine such as DL-cysteine hydrochloride, or a salt thereof; homocysteine or a salt thereof; thiomalic acid or a salt thereof; thiolactic acid or a salt thereof; cysteamine or a salt thereof; thioglycerin or the like. It is not limited to the examples.

The content of the reducing agent may be an amount sufficient to exert its function, and is usually 3 to 12% with respect to the first type agent composition for an aerosol type permanent wave, especially.
It is preferably 4.5 to 7.5%.

The aerosol type first agent composition for permanent wave of the present invention contains, as an essential component, a propellant consisting of the solvent and a liquefied gas and / or a compressed gas. In the present invention, purified water and the like are further added. Water is preferably used.

The water is preferably contained in the aerosol type permanent wave first agent composition in an amount of 60% or more, and when the content of water is less than 60%, hydrogen bond and salt bond of the hair. Since the effect of cutting the hair tends to be difficult to obtain, the wave formation of the hair tends to be slow.

The first agent composition for an aerosol type permanent wave according to the present invention comprises a propellant and a reducing agent consisting of the above solvent, liquefied gas and / or compressed gas, and water, as well as, for example, ammonium carbonate, ammonium hydrogen carbonate, Carbonates such as sodium carbonate and sodium hydrogen carbonate, anionic surfactants such as sodium lauryl sulfate, other various surfactants commonly used in cosmetics, pH adjusting agents such as ammonia water, emulsifiers, penetrants,
Appropriately add hair nourishing agents, chelating agents such as ethylenediaminetetraacetic acid (EDTA) or salts thereof, coloring agents, fragrances, and various additives for the purpose of protecting hair within a range that does not affect the function of the reducing agent. You can

The method for preparing the first agent composition for aerosol type permanent wave of the present invention is not particularly limited,
The solvent, the reducing agent and other various components are appropriately added to water, and the mixture is mixed with a propellant composed of a liquefied gas and / or a compressed gas, and a usual method is used for a pressure container for an aerosol generally used. There is a method of filling with.

The first agent composition for an aerosol type permanent wave of the present invention obtained as described above has the above-mentioned p content.
It is preferable to adjust the pH to 7 to 10, especially 8 to 9 by adding an H adjuster or the like. Such pH
When the value is less than 7, the wave formation tends to be weak, and when it exceeds 10, the hair tends to be damaged.

Further, the first agent composition for an aerosol type permanent wave of the present invention has an internal pressure of 1.2 to 5 kg / cm ² · when filled in a pressure container for an aerosol, for example.
G, especially 1.5 to 3 kg / cm ² · G is preferably adjusted. When the internal pressure is less than 1.2 kg / cm ² · G, it is necessary to relatively increase the amount of propellant, and it tends to be difficult to provide a desired injection form. ^If it exceeds ^2. G, the liquid tends to be scattered, an appropriate amount of the composition may not adhere to the hair, or an appropriate spraying state may not be obtained.

The aerosol type first agent composition for permanent wave of the present invention may be sprayed in the form of foam, mist, thread or the like. In practice, it is usually in the form of foam and the sprayed foam is It is very preferable that the crushed state is quick (foam break) rather than being kept stable. Such foams can be adjusted by adjusting the type and amount of surfactant.

When the aerosol type first agent for permanent wave of the present invention is used, a second bromate-based permanent wave agent such as sodium bromate or potassium bromate as a second agent is used. A hydrogen peroxide-based second agent for permanent wave and the like can be used. Further, it is not particularly necessary that the second agent is an aerosol type.
