Abstract:
1. A method for cleansing the skin comprising scrubbing the skin with a scrub agent comprising hydrogel particles comprising bubbles and having a specific gravity of 0.7 to 1.00 and an average particle diameter of 50 to 500 μm, wherein the hydrogel particles are obtained by a process comprising: stirring an aqueous solution comprising 0.1 to 8.0 percent by weight of a gel-former and 0.5 to 5.0 percent by weight of a bubble-regulating agent to form a bubble-containing hydrogel and water, and then discharging the bubble-containing hydrogel through a pore into a gaseous phase or a liquid phase to form bubble-containing hydrogel particles, or spraying the bubble-containing hydrogel through a spray nozzle into a gaseous phase to form bubble-containing hydrogel particles.
