Description

  The present invention relates to a cosmetic, and more particularly, to a cosmetic suitable for a so-called “post-form” cosmetic that does not foam when taken out of a container and foams after use.

  Among the aerosol cosmetics, the form at the time of discharge is a normal cream or gel, and the so-called “post foam cosmetic” that foams to form a foam by rubbing and applying is a foam at the time of spreading the coating. It is applied to cosmetics in various fields such as hair cosmetics and cleaning cosmetics because of its gentle touch, excellent usability and the ability to evenly apply an appropriate amount on the skin. It is attracting attention as a new dosage form. (For example, see Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4, Patent Document 5, and Patent Document 6) Usually, such a post-form cosmetic is compared with a normal foamed aerosol cosmetic. It is created with a configuration in which the content of vaporized components such as fluorocarbons and liquefied natural gas is reduced. However, in the present situation where aerosol cosmetics are difficult to use due to environmental considerations, it is desired to develop post-form cosmetics that do not contain vaporized components.

  ADVANTAGE OF THE INVENTION According to this invention, the post foam cosmetics of a vaporization component non-containing form can be provided.

(1) Carbonate and / or bicarbonate which is an essential component of the cosmetic of the present invention The cosmetic of the present invention is in a post-foam form and contains carbonate and / or bicarbonate as an essential component. Examples of carbonates or bicarbonates include alkali metal salts such as sodium and potassium salts, alkaline earth metal salts such as calcium and magnesium, ammonium salts, triethanolamine salts, and triethylamine salts. Preferred examples include organic amino acid salts, basic amino acid salts such as lysine salts and arginine salts. Particularly preferred is sodium carbonate or sodium bicarbonate. This is because the amount of carbon dioxide generated per weight is large, and the reaction with the organic acid occurs quickly. In the cosmetic of the present invention, such carbonates or bicarbonates can be contained alone or in combination of two or more. The preferred content of such carbonates and bicarbonates in the cosmetics of the present invention is 1 to 10% by mass, more preferably 3 to 5% by mass, based on the total amount of the cosmetics. . This is because if the amount is too small, foaming may not be sufficient, and if the amount is too large, the foam texture may be impaired.

(2) Organic acid-containing microcapsules that are essential components of the cosmetic of the present invention The cosmetic of the present invention is characterized by containing organic acid-containing microcapsules as an essential component. Techniques in which liquid or solid oil raw materials and polyhydric alcohol are contained in microcapsules and contained in cosmetics are already known (for example, Patent Document 10, Patent Document 11, Patent Document 12). It can be manufactured by applying such a known technique. The microcapsules that can be used in the cosmetic of the present invention can be used without particular limitation as long as it is a commonly used raw material. For example, any of natural materials such as gelatin or synthetic materials such as resins can be used. Can be used. Particularly preferably, the basic structure is a resin. As the capsule of the resin, the basic structure of the capsule is a homopolymer or copolymer formed from one or more monomers selected from acrylic acid ester, methacrylic acid ester, vinyl acetate and styrene, or the monomer and acrylic acid , Methacrylic acid, divinylbenzene, and a resin capsule made of a copolymer selected from a monomer selected from ethylene glycol dimethacrylate are preferable. Among these, the resin capsule encapsulates a solid or liquid organic acid, and the capsule The amount of organic acid included in the capsule is 50 to 90% by mass of the whole capsule, the particle diameter of the capsule is 2 to 20 μm, and the pressure resistance (breaking) strength is ² to 40 kg / cm ^2. A spherical resin capsule is preferred. Such microcapsules emulsify the contents and the constituent monomers of the polymer that forms the outer shell of the capsule, and then add a polymerization initiator such as azobisisobutyronitrile or benzoyl peroxide to the emulsion polymerization. Just do. As a surface active component used for such emulsification, for example, hexlite sold under the name of “Laponite XLG” can be suitably exemplified. The preferable content of such a surfactant component is 0.01 to 5% by mass, and more preferably 0.05 to 1% by mass. This is because if it is too much, the inclusion rate is lowered and the partition walls are weakened. These and partition wall components 1 to 5% by mass, the included organic acid 5 to 9% by mass, and the remainder as a reaction solvent such as water, an emulsion system in which droplets are dispersed by mechanical force is formed, and a polymerization initiator is added thereto. In addition, emulsion polymerization is carried out, the resulting microcapsules are separated by means such as centrifugation, and washed if desired, whereby the organic acid-containing microcapsules of the present invention can be produced. Examples of the liquid or solid organic acid to be encapsulated include dibasic acids such as adipic acid, succinic acid, and succinic acid, hydroxycarboxylic acids such as malic acid, citric acid, lactic acid, and glycolic acid, oleic acid, linoleic acid, Fatty acids such as linolenic acid, lithinolic acid, stearic acid, lauric acid, myristic acid, palmitic acid, behenic acid and the like can be preferably exemplified, and fatty acids can be particularly preferred, among which a fatty acid which is liquid at 1 atm and 25 ° C is preferred, Specifically, oleic acid, linoleic acid, linolenic acid and the like are particularly preferable. These can contain only the seed | species, and can also contain them in combination of 2 types. The content of the organic acid-containing microcapsules in the cosmetic of the present invention is preferably 1 to 20% by mass, more preferably 5 to 15% by mass. This is because if the amount is too small, foaming may not be sufficient, and if the amount is too large, the organic acid becomes excessive, and the feeling of use may be impaired by the unreacted organic acid.

(3) Cosmetics of the present invention The cosmetics of the present invention are post-form cosmetics, and contain 1) the carbonate and / or bicarbonate and 2) the organic acid-containing microcapsules. It is characterized by. By taking such a configuration, the cosmetic of the present invention gradually foams with the rubbing action, and accordingly, the strength of the irritation due to the rubbing becomes soft and the comfort aroused by the rubbing action increases. Have the following characteristics: Thereby, in massage etc., it is possible to avoid excessive stimulation due to friction by rubbing and to further enhance the effect of massage. Moreover, the thermal sensation obtained by the massage can be maintained for a long time due to the heat insulating effect of the foam generated by the foaming, and thereby the blood flow can be further increased. Further, since the cosmetic itself does not contain a vaporizing component, it can be filled and stored in a normal non-pressure-resistant container, thereby eliminating the need to puncture the container as in the case of disposal of an aerosol can. Further, the solvent effect of the liquefied gas component does not reach the skin, and in addition, the effect of increasing the blood flow rate by carbon dioxide gas can be obtained. From such various features, the cosmetic of the present invention is preferably applied to massage cosmetics. Of course, the comfort of use due to foaming during application spreading is also manifested in other cosmetics as well, and is a desirable property in other cosmetics, so the cosmetic of the present invention is applied to cosmetics other than massage cosmetics. It is also within the technical scope of the present invention.
