    • The present invention provides a method of making a nanoemulsion comprising the steps of: 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 if the solvent is a glycol ether it is not diethyleneglycol monobutyl ether; b) mixing the silicone resin solution from a) with an aminosiloxane polymer to obtain an aminosiloxane polymer:silicone resin mixture having ratio of about 20:1; c) allowing the aminosiloxane polymer:silicone resin mixture to age for at least about 6 hours at ambient temperature; d) adding the aminosiloxane polymer:silicone resin mixture to a vessel; e) optionally adding with agitation an additional organic solvent to the aminosiloxane polymer:silicone 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; and a nanoemulsion preparable by said method.
    • 本发明提供制备纳米乳液的方法,其包括以下步骤:a)将有机硅树脂溶解在有机溶剂体系中以产生约80%或更低的有机硅树脂溶液浓度,其中有机溶剂体系包含选择的单一溶剂 选自一元醇,多元醇,一元醇的醚,多元醇的醚,脂肪族酯,格尔伯特醇,异链烷烃,萘酚,乙二醇醚,但如果溶剂为二醇醚则不是二甘醇单丁醚; b)将来自a)的有机硅树脂溶液与氨基硅氧烷聚合物混合以获得氨基硅氧烷聚合物:具有约20:1的比例的有机硅树脂混合物; c)使氨基硅氧烷聚合物:有机硅树脂混合物在环境温度下老化至少约6小时; d)将氨基硅氧烷聚合物:有机硅树脂混合物加入到容器中; e)任选地在搅拌下向氨基硅氧烷聚合物中加入另外的有机溶剂:有机硅树脂混合物; f)混合直至均匀; g)加入质子化剂; h)另外加入一定量的含水载体以产生所需浓度的乳液; 和通过所述方法制备的纳米乳液。
