Incorporation of a watersoluble compound into a lipid

摘要

A water soluble active material (I) is incorporated into a fatty material (II) by the following method: a) lecithin is treated to give a fraction practically free from phosphatidyl choline; b) an aqueous solution of (I) is incorporated into a mixture of the lecithin fraction and (II) under vigorous agitation and in sufficient quantity to ensure hydration of the lecithin fraction, thus forming a heterogeneous mixture, and c) this mixture is dried to form a homogeneous product.
