Description

  The present invention relates to a foamy aerosol cosmetic, and more particularly to a foamy aerosol cosmetic suitable for a cleansing cosmetic.

  In the form of a topical skin preparation, a large surface area can be obtained at the time of administration, and since the spread on the skin is light, it is necessary to administer the composition to a fine part, This is effective when it is necessary to administer the drug with low irritation. From this point of view, there are examples where antibiotics used for wounds are applied. Usually, such a foam dosage form is formed by ejecting an oil-in-water emulsion emulsified with soap or a nonionic surfactant with a gas or the like. Among such techniques, those utilizing nonionic surfactants are known. (For example, refer to Patent Document 1 and Patent Document 2) However, there is no known foam-like composition using a nonionic surfactant and having an extremely small aqueous component and mainly an oil component. This is because it was difficult to form a foam having excellent stability with only the oil component. Foam aerosols mainly composed of oil components are already known (see, for example, Patent Document 3 and Patent Document 4), both of which use an anionic surfactant as a surfactant. . In cosmetics, cleansing materials, cleaning materials, and the like are known as those that are easily stimulated by the makeup operation. Attempts have already been made to develop a foam cleansing material or a cleaning material, paying attention to the low irritation when using the foam cosmetic. (See, for example, Patent Document 5 and Patent Document 6) and the like are known, but these are all foam-like compositions of an aqueous component, and the range of the effect exceeds that of an aqueous cleaning material. Absent. Therefore, at present, a foam-type cleansing material aiming at oily dirt and makeup removal, especially a foam-type cleansing material composed mainly of an oil-based component has not been obtained yet. That is, it has been desired to develop a cosmetic suitable for cleansing that has a lot of oily components, has performance as an oil-based cleansing, and has little irritation during use due to the properties of the foam. The current situation is not.
