<p>The invention provides resin particles which are excellent in storage stability and feelings in use and can be effectively adsorbed and retained on the skin, hair, fibers or the like to exhibit effectively the effects resulting from metal oxide fines, for example, UV-screening, antimicrobial, and deodorant effects: a process for producing the resin particles; and cosmetics containing the same. The invention relates to resin particles containing a metal oxide and having a ΔT (%) value of 20 or above as defined by the following formula; resin particles made of a crosslinked hydrophilic synthetic polymer and containing a metal oxide; a process for producing the resin particles; and cosmetics containing the same: ΔT (%) = transmittance(%) (550nm) - transmittance(%) (350nm) wherein each transmittance is determined by using an aqueous dispersion obtained by dispersing the resin particles in water at such an amount as to give a metal oxide concentration of 0.01 % by mass.</p> |
