General description

Silicon oils constitute a group of hydrophobicpolymeric compounds with a linear chain of siloxanerepeating units (–Si–O) and a variety of side chains. Owing to their uniqueproperties like wettability, lubrication, smooth gliding behavior, andmechanical strength, they are widely used in electric insulators, anti-foaming,laboratories, and lubricants.
Silicone oil is a low viscosity, liquid polymerized, siloxane with organic side chains. Silicone oil exhibits antimicrobial activity against endopthalmitis causing microorganisms under in vitro conditions.

Application

Silicone oilcan be used as an intraocular liquid in vitreoretinal surgery as it canmaintain the adhesion between the retina and retinal pigment epithelium.

It can be used in a two-phase partitioning bioreactor totreat gas effluents. Silicon oils are compatible with the aqueous phase andlead to better emulsion between the two phases.

Itcan also be used to generate hydrophobic coatings on glass surfaces.(4)
