Nanoemulsions are prepared by: a) solubilizing a silicone resin in an organic solvent system to yield a silicone resin solution concentration of about 80% or less, wherein the organic solvent system comprises a single solvent selected from the group consisting of monoalcohols, polyalcohols, ethers of monoalcohols, ethers of polyalcohols, fatty esters, Guerbet alcohols, isoparaffins, naphthols, glycol ethers, provided that the solvent is not diethyleneglycol monobutyl ether; b) mixing the silicone resin solution with an aminosiloxane polymer to obtain an aminosiloxane polymer:silicone resin mixture having ratio of about 20:1; c) allowing the resin mixture to age for at least about 6 hours at ambient temperature; d) adding the resin mixture to a vessel; e) optionally adding with agitation, an additional organic solvent to the resin mixture; f) mixing until homogenous; g) adding a protonating agent; h) additionally adding an aqueous carrier in an amount to produce the desired concentration of emulsion.

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.
