Description

  The present invention relates to a cosmetic, and more particularly to a cosmetic suitable for a foam-forming cosmetic.

  Among cosmetic dosage forms, there are two types of aerosol cosmetics: 1) spray cosmetics and 2) foam-forming cosmetics. A spray cosmetic is a composition having a relatively low viscosity that is sprayed in a mist with a relatively high-pressure gas. A foam-forming cosmetic is an emulsion having a relatively high viscosity whose interface is reinforced with higher alcohol. The liquid is discharged while forming bubbles with a relatively low pressure gas. In the past, fluorinated hydrocarbons have been used as the gas for ejection and discharge, but in recent years they have been replaced with natural gas or the like for environmental considerations. However, in liquefied natural gas, there are problems of lowering jetting properties and discharging properties in a low temperature region, and lowering of fat solubility under such conditions has been an unavoidable problem. That is, it has been desired to develop an aerosol cosmetic that is a system that does not use fluorinated hydrocarbons and that is excellent in low-temperature ejection properties or ejection properties.

  On the other hand, carbon dioxide is a cosmetic and is used for the purpose of promoting blood circulation. As such a usage form, for example, it is known that it is used in the form of an effervescent tablet in a bath agent. (For example, refer to Patent Document 1 and Patent Document 2) For cyclic carbonates such as ethylene carbonate and propylene carbonate, plasticity in the coating is known, and is used as a plasticizer in nail colors and the like. (See, for example, Patent Document 3, Patent Document 4, and Patent Document 5) However, foam-forming cosmetics containing carbon dioxide or cyclic carbonates are not known, and by containing such components at low temperatures Also, it has not been known at all that a foam-forming cosmetic material excellent in dischargeability can be obtained.
