ABSTRACT:
According to this invention, a microemulsion of an organopolysiloxane containing cyclohexylamino groups is prepared as follows: component (A), an organopolysiloxane containing cyclohexylamino groups and component (B), a nonionic surfactant and component (C), ethylene glycol or propylene glycol are blended. Formic acid or acetic acid, component (D) and water, component (E), are then added. The mixture is then stirred to form an emulsion precursor liquid, which is then dispersed in a prescribed amount of water. The microemulsion of the organopolysiloxane containing cyclohexylamino groups prepared using the method of this invention has an excellent shelf stability.
