Abstract: 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.

Abstract: Nanoemulsions are prepared by: a) solubilizing a silicone resin in an organic solvent system to yield a silicone resin solution concentration of 80% or less, wherein the organic solvent system comprises diethyleneglycol monobutyl ether and at least one additional solvent; b) mixing the silicone resin solution from a) with an aminosiloxane polymer to obtain an aminosiloxane polymer: silicone resin mixture; 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) adding an aqueous carrier in an amount to produce a desired concentration of emulsion.
