Document Type and Number:
WIPO Patent Application WO/2023/157333
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an aerosol composition that does not substantially contain a surfactant and has good dispersion stability even when an oily component is contained in a large amount. This problem is solved by an aerosol composition containing water, an oily component, and a water-soluble polymer, wherein the water-soluble polymer contains at least one selected from the group consisting of polyvinyl alcohol and polyvinyl pyrrolidone, the content of the water-soluble polymer in the aerosol composition is 0.01-2.5 mass%, the aerosol composition forms an emulsion, the average particle size of the droplets of the emulsion is 0.5-7.0 μm, and the aerosol composition does not substantially contain a surfactant.
