Abstract
Disclosed is a process of making silicone-in-water emulsion, compositions including a silicone-in-water emulsion and use of the compositions as an additive in paint and coating formulations, printing ink compositions, personal care products, textiles, leather and indirect food contact applications. The process includes contacting a silicone with an organic non-polar solvent, adding an anionic surfactant, and further adding water under shear, to obtain a silicone-in-water emulsion; and removing the non-polar solvent, wherein the silicone-in-water emulsion has a particle size distribution Dv50 in the range from ≥0.1 μm to ≤25 μm, determined according to dynamic light scattering technique with a fixed scattering angle of 90°.
