Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a composition for forming a foam, wherein at least two compositions are mixed at the time of use, and more particularly to a composition suitable for cosmetics not using Freon gas.

[0002]

2. Description of the Related Art An aerosol composition which forms a mousse is used in packs, detergents, etc. due to its good usability, such as good sealability due to foam, good cleanability due to the large surface area, and soft feeling of use. It has been widely used in cosmetics and cleaning compositions. In particular, in pack cosmetics, the properties of such aerosol foams were suitable for pack cosmetics. However, chlorofluorocarbon, which is the base gas for this foaming, is considered to be a cause of destruction of the ozone layer, and its use is greatly restricted, so that aerosols for forming conventional foams are practically impossible. As an alternative gas to CFCs in the aerosol forming such a foam, for example, liquefied natural gas and the like have been considered, but such a gas is flammable and is not suitable for use in cosmetics and the like. If possible, it is desirable to use a non-flammable gas. In the case of using a gas, there is a problem such as an explosion accident in the disposal of aerosol cans, and a foam is formed without taking such a form. Means for doing so were also desired. That is,
In other words, it has been desired to develop a foam-forming composition that does not affect the environment and has a low risk of causing an explosion accident or the like. Such technology is not only for cosmetics, but also for decolorization, deodorization and mold removal of hypochlorite, stain remover for partial use of clothes, dish detergent, bath It has also been desired in detergents, topical skin disinfectants, topical skin medicines and the like.

On the other hand, a technique of mixing at least two kinds of compositions, ie, a composition containing a carbonate and a composition containing an acidic component, to generate carbon dioxide gas is a known technique. The formation of foams has not been performed at all using carbon dioxide gas generated by mixing with carbon dioxide as a base gas.

[0004]

SUMMARY OF THE INVENTION The present invention has been made under such circumstances, and an object of the present invention is to provide a foam-forming composition which does not affect the environment and is less likely to cause an explosion accident. Make it an issue. Hereinafter, the present invention will be described in detail focusing on embodiments.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION (1) Cosmetic of the present invention The cosmetic of the present invention is a cosmetic which forms a foam with carbon dioxide gas, and 1) a cosmetic composition containing a carbonate, 2) At least two independent compositions of a cosmetic composition containing an acidic component are used as constituents, and the constituents are mixed on or immediately before the skin. In the cosmetic of the present invention, the number of the independent compositions may be three or more, but it is necessary that the two independent compositions are included therein. Here, the term “independent composition” means a form in which the compositions do not exist in a mixed state at the time of commercial use, but are mixed at the time of use or immediately before. That is, at the time of marketing, the components of the independent compositions are not mixed. These compositions can take any form as long as they can be taken in cosmetics. For example, a composition such as a uniform one-phase solution, an emulsion composition, a powder composition, a dispersion composition Any of the materials can be used, and the forms of the constituent compositions can be different. However, from the requirement of forming a foam, it is required that at least one of the constituent compositions is a composition containing an aqueous component. Any of the constituent compositions of the present invention may contain optional components usually used in cosmetics, in addition to the above essential components. Such optional components include, for example, hydrocarbons such as petrolatum and microcrystalline wax, esters such as jojoba oil and gay wax, triglycerides such as tallow, olive oil, higher alcohols such as cetanol and oleyl alcohol, and stearic acid. , Fatty acids such as oleic acid, polyhydric alcohols such as glycerin and 1,3-butanediol, nonionic surfactants, anionic surfactants,
Preferred examples thereof include cationic surfactants, amphoteric surfactants, thickeners such as ethanol and carbopol, preservatives, ultraviolet absorbers, antioxidants, dyes, and powders. Among these optional components, particularly preferred ones are selected from fatty acids such as stearic acid, oleic acid, isostearic acid and / or salts thereof, glycerin, 1,3-butanediol, dipropylene and 1,4-pentanediol. One or two or more combinations are contained as polyhydric alcohols. This is because each of these has a favorable effect on maintaining the foam. Of these, the fatty acid and / or its salt is preferably contained together with the carbonate. Of these,
The fatty acid and / or salt thereof is preferably contained in an amount of 0.1 to 20% by weight, more preferably 0.5 to 18% by weight in terms of the amount of the fatty acid in the final form to be administered to the skin. , Glycerin and 1,3-butanediol, dipropylene glycol and 1,4-pentanediol as one or more combinations of 8 to 2
It is preferably 0% by weight, more preferably 9 to 18% by weight.
Glycerin: The ratio of one or more selected from 1,3-butanediol, dipropylene and 1,4-pentanediol is preferably 1: 3 to 3: 1.

(2) Carbonate which is an essential component of the cosmetic of the present invention The cosmetic of the present invention is characterized by being an independent constituent composition containing a carbonate. As the carbonates that can be used in the cosmetic of the present invention, those that are usually used in cosmetics can be used without any particular limitation. For example, sodium carbonate, potassium carbonate, sodium hydrogencarbonate, potassium hydrogencarbonate Salts of alkali metal and carbonic acid or bicarbonate, such as
Preferred examples include salts of alkaline earth metals such as calcium carbonate, magnesium carbonate, calcium bicarbonate and magnesium bicarbonate with carbonic acid or bicarbonate, and salts of ammonia such as ammonium carbonate and ammonium bicarbonate with carbonic acid or bicarbonate. it can. These may contain only one kind, or may contain two or more kinds in combination. Of these, particularly preferred are salts of alkali metals with bicarbonate or salts with carbonic acid, of which sodium bicarbonate is particularly preferred. This is because a form in which carbon dioxide gas is generated by decomposition of a bicarbonate with an acid is preferable for foam formation, and among them, sodium bicarbonate and sodium carbonate are particularly preferable. The preferred content of these carbonates in the cosmetic of the present invention is 0.1 to 5% by weight in the form finally administered to the skin.
And more preferably 0.5 to 3% by weight. This is because if the amount is too small, the foam may not be formed, and if the amount is too large, the foam formation may be inhibited.

(3) Acidic component which is an essential component of the cosmetic of the present invention The cosmetic of the present invention is characterized in that a composition containing an acidic component as an essential component is an independent constituent composition. The requirement for the acidic component is to generate carbonic acid when mixed with the carbonate, in other words, an acid that is stronger than carbonic acid. Examples of the acid include mineral acids such as phosphoric acid, organic acids such as oxalic acid and citric acid, and salts thereof. Among them, organic acids are preferable, and citric acid and / or salts thereof are particularly preferable. Of course, these may contain only one kind, or may contain two or more kinds in combination. The preferred content of these acidic components in the cosmetic composition of the present invention is 0.1 to 10% by weight, more preferably 0.5 to 10% by weight in the final form to be administered on the skin.
~ 5% by weight. This is because if the amount is too small, the amount of carbon dioxide gas generated may be insufficient, and if the amount is too large, the foam-forming ability may reach a plateau and irritation by acid may increase.

(4) Compositions Other than the Cosmetic of the Present Invention The cosmetic of the present invention is applied to the field near cosmetics, and can utilize the preferable properties derived from foams as in the case of cosmetics. it can. Such a technique also belongs to the technical scope of the present invention. Such application fields include, for example, decolorizing / deodorizing / fungus removing agents containing hypochlorite, etc., stain removers for partial use of clothes, dishwashing detergents, bath detergents and medicines such as antibiotics. Preferred examples include a skin external disinfectant and a skin external medicine. These can be produced by adding these active ingredients to the above components.
