Abstract
Provided are oil-in-water and water-in-oil emulsion compositions including from 0.01 to 5 wt % of a halogenated elastomer emulsifier, and optionally from to 0.5 wt % of a polyalkylene amine co-emulsifier. The emulsion compositions disclosed herein provide for increased interfacial elasticity and decreased interfacial tension at the oil-water interface to increase resistance to coalescence of dispersed water droplets of a water-in-oil emulsion or oil droplets of an oil-in-water emulsion. The emulsion compositions disclosed herein are suitable for lubricant applications due to their resistance to shear thinning.
