The present disclosure provides a composition for use in drilling fluids comprising an adsorbing substrate that is loaded with a hydrophobic liquid. In one aspect, the hydrophobic liquid comprises a base oil, an emulsifier, a rheology modifier, a viscosifier, a quaternary amine or a mixture thereof. The composition may be combined with an oil- based or hydrocarbon continuous phase, and an aqueous dispersed phase to form a non- aqueous phase invert emulsion for use in drilling applications. |
