<p>A simple and cost-effective process for making stable and high particle size silicone emulsion especially in the range of 1-100 micron involving a selective combination of organopolysiloxanes, emulsifiers and water in a single process. Importantly apart from the selective use of emulsifier to achieve the desired high particle size emulsion the quantity of the emulsifiers are selective for obtaining the stable emulsion. The process of making high particle organopolysiloxane emulsion makes advantageous use of surfactant / surfactants having a critical HLB value that help to mix oil and water easily without need for complex manipulative steps or precautions while water addition. Moreover, the present invention further identifies the importance of the selective use of thickener which has an important role in achieving a stable high particle emulsion with good shelf life.</p> |
