Abstract: The present invention provides resin beads that can provide various types of products, such as a cosmetic having excellent tactile impression, such as spreadability on the skin, moist feeling, and softness, and having high stability such that such tactile impression is kept over a long period of time, that can be substituted for resin particles composed of a synthetic material derived from petroleum, and that have favorable biodegradability. The present invention also provides various types of products, such as a cosmetic, using the resin beads. The resin beads are obtained by surface-treating, with a solid surface treatment agent, core beads formed with a resin containing cellulose as a main component, and have a cumulative 50% particle size on a volume basis of 50 μm or smaller, a degree of sphericity of 0.7 to 1.0, a degree of surface smoothness of 70 to 100%, and a degree of crystallinity of 60% or less. In addition, the present invention provides a product of any one of a cosmetic, a dermatological preparation, a paint, a shaped article, a film, a coating agent, and a resin composition which contain the resin beads.

Abstract: The present invention provides a method for producing resin beads which can provide various types of products, such as cosmetics, imparted with superior tactile impression, spreadability on the skin, transparency, and product stability, and which can be substituted for resin particles composed of a synthetic material derived from petroleum. The method is a method for producing resin beads containing a cellulose derivative as a main component. The production method includes: a suspension preparation step of mixing an oil phase containing the cellulose derivative and an organic solvent that dissolves the cellulose derivative, the organic solvent having a water-solubility of 0.1 to 50.0 g, and an aqueous phase containing a dispersion stabilizer, thereby preparing a suspension containing oil droplets containing the cellulose derivative and the organic solvent; and an oil droplet contraction step of adding water to the suspension, thereby contracting the oil droplets, wherein the water is added to the suspension in such a way as to satisfy the following expression (A) until a content of the organic solvent in the suspension becomes equal to or less than the water-solubility of the organic solvent. (W/S)/T≤1.00 (A), wherein W: an addition amount of water (parts by mass),
S: an amount of the suspension (parts by mass), and
T: a time (minutes) required for addition.
