Compounds are non-volatile and stable at room temperature.
PDMS is a very poor solvent, so you're not likely to have much success in making solutions. There are specialized silicone surfactants, used in cosmetics, that might let you prepare suspensions.
Dear Subhrajyoti,
Poly(dimethylsiloxane), dimethylpolysiloxane, dimethylsilicone fluid,
dimethylsilicone oil (PDMS) consists of fully methylated linear siloxane polymers containing repeating units of the formula (CH3)2SiO, with trimethylsiloxy end-blocking units of the formula (CH3)3SiO. It is a clear, colourless, viscous liquid. Polydimethylsiloxane is frequently used in commerce as such, as a liquid containing 4-5% silica gel, and as an aqueous emulsion formulation containing, in addition to silica gel, emulsifiers and preservatives. It is Insoluble in water and in ethanol; soluble in carbon tetrachloride, benzene, chloroform, diethyl ether, toluene and other organic solvents. It is used variously in the cosmetic and consumer product industry as well. For example, PDMS can be used in the treatment of head lice on the scalp and dimethicone is used widely in skin-moisturizing lotions where it is listed as an active ingredient whose purpose is "skin protection." Some cosmetic formulations use dimethicone and related siloxane polymers in concentrations of use up to 15%.
Based on the properties indicated in the above text, it is clear that PDMS is not a good solvent for organic non-volatile hydrophilic compounds. These compounds should be suspended or emulsified when using PDMS as a solvent.
