Abstract (en)
[origin: WO9118613A1] The present invention provides compositions and method for the preparation of emulsions and multiple emulsions. Specifically, the invention provides solids which are self-emulsifying glasses which, on contact with a sufficient amount of an aqueous phase, form emulsions or multiple emulsions without input of emulsive mixing. Emulsions and multiple emulsions produced from the self-emulsifying glasses are encompassed by this invention. The self-emulsifying glasses are prepared from certain matrix compounds and an oleaginous material by a solvent method. The glass results from removal of solvent from a combination of matrix compound, oleaginous material and a solvent which dissolves substantially all of the matrix compound. Multiple emulsions result from glasses in which the oleaginous phase is a primary, e.g. water-in-oil emulsion. The glasses and emulsions produced therefrom are particularly useful pharmaceutical, food and cosmetic applications.
