Abstract
Abstract Wax polishing compositions in the form of a double emulsion wherein the continuous phase comprises organic solvent, organopolysiloxane and water-in-oil emulsifier and the discontinuous phase comprises aqueous particles having dispersed particles of wax therein. Compositions are prepared by adding at room temperature an aqueous media containing emulsified wax to a solvent solution containing organopolysiloxane and water-in-oil emulsifier, also at room temperature.
