  • Patent number: 5244598
    Abstract: A method is provided for preparing an amino-functional polyorganosiloxane microemulsion having an average particle size of from about 0.015 to about 0.05 microns by (A) forming an oil mixture by blending (1) an amino-functional polyorganosiloxane and (2) at least one surfactant, wherein at least one of the surfactants is insoluble in the amino-functional polyorganosiloxane; (B) dropwise adding an initial portion of water to the oil and surfactant mixture prepared in step (A), agitating the mixture formed in step (B) for a period of time sufficient to form a homogeneous mixture; (C) adding water to the homogeneous mixture formed in (B); and (D) adding a lower aliphatic carboxylic acid having from 1 to about 4 carbon atoms or a mineral acid selected from HCl, H.sub.2 SO.sub.4, HNO.sub.3, HBr, or Hl to the mixture formed in (C) in an amount sufficient to provide the mixture with a pH of from about 4 to about 7, the acid reacting with the amino-functional polyorganosiloxane (A)(1) to form a water-soluble salt.
