Abstract
Abstract Improved wax compositions comprising certain hydrocarbon ester-containing organopolysiloxanes are disclosed. These compositions have improved shelf stability and excellent luster-bestowing properties, lubricating properties and water-repellent properties. They are useful in textile manufacture, such as treating sewing threads and textile warps, and for protecting surfaces, such as furniture surfaces and automobile surfaces.
