Abstract
Oil-in-water (O/W) and water-in-oil (W/O) emulsions and microemulsions containing silanes or siloxanes having quaternary ammonium groups are made by reacting organic quaternary ammonium compounds having epoxide groups or halohydrin groups, with silanes or siloxanes having amino groups. The reaction is carried out in an aqueous polar phase containing a surfactant. The emulsions and microemulsions are especially useful for treating hair, skin, or the underarm.
