The following is water in PDMS, but it may still have some useful information:

Hope it's useful, best of luck!

Hello,

using an ultraturax to prepare the emulsion of PDMS in water should work, as soon as the ratio PDMS over water is small (small quantity of PDMS).

Sylgard 184 is a complex mixture, I am not sure additionnal surfactant should be added.

We produced a paper on emulsions containing slygard 184

Even this topic is 5 years old, I would like to ask if somebody has tried to emulsify PDMS or OH-terminated PDMS in water with "silicone" surfactants? These are polydimethylsiloxane backbone and polyether hydrophilic chains, sometimes OH captured. Typical surfactants are DC198, DC193, Momentive SR234, most of them used as stabilizers / emulsifiers in production of rigid or flex polyurethane foams.
