Abstract
A process is provided for preparing an aqueous emulsion of an amino-functional polyorganosiloxane. The process includes mixing A) an amino-functional polyorganosiloxane, B) a non-ionic surfactant, and C) water; and thereafter mixing in additional starting materials including additional water, D) a water soluble salt, E) a pH adjusting agent, and F) a preservative. A phase inversion occurs during the process, such that the resulting emulsion has A) the amino-functional polyorganosiloxane in the internal, discontinuous phase and C) the water in an external, continuous phase.
