Description

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

  By taking the foam structure of the foam aerosol, a cosmetic composition having a very large area can be brought into contact with the skin. Utilizing such foam characteristics, it can be applied to pack cosmetics for the purpose of more effectively transdermally absorbing active ingredients, applied to cleansing cosmetics for the purpose of improving dirt removal effects, or hair Attempts have been made to apply it as a mousse dosage form for the purpose of administration uniformly and without causing dripping or the like in a place where there is a large three-dimensional change. However, as foam formation requirements, since the foam structure is maintained by utilizing the tension of the interface formed by the higher alcohol and the surfactant, there is a limit to the blending of ingredients that break the interface, and the gloss is limited. It was impossible to apply it to hair-styling materials. For this reason, a search for a surfactant that creates a foam interface that is hard to break even when a glossy component such as silicone coexists has been made, and a fatty acid ester of polyglycerol has been found as such a surfactant. Yes. (For example, see Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4) Although the foam interface that is hard to break is realized by the inclusion of such components, it still contains components such as silicone. In reality, this is not enough.

  On the other hand, in the aerosol cosmetics, it is a foamy aerosol cosmetic containing 70 to 95% by mass of an oily component having fluidity at 1 atm of 25 ° C., which contains at least two types of polyglycerol fatty acid esters. Nothing has been known at all, and it has not been known at all that those having such a configuration can maintain foam formation even when an antifoaming component such as silicone is contained.

Is particularly preferred. This is because, on the one hand, it is easy to form a stable foam, and on the other, it is suitable as a uniform dispersion medium for the gloss imparting component. Further, from the same viewpoint, it is preferable to further contain a diester of N-acylglutamic acid. In this component, the acyl group constituting the diester of N-acylglutamic acid is preferably a linear aliphatic acyl group having 10 to 32 carbon atoms, for example, lauroyl group, myristoyl group, palmitoyl group, stearoyl group, behenoyl group.
