Abstract

The invention relates to the preparation of organopolysiloxane microemulsions, wherein the components (A) organopolysiloxane, (B) emulsifier, (C) water, optionally, (D) cosurfactant and optionally (E) acid are brought together and mixed in any desired sequence. Microemulsions are formed spontaneously without introduction of energy in the form of heat or severe shearing forces.
