A silicone gel (“silogel”) composition used to deliver pharmaceutical products transdermally as well as a method for producing the silogel composition, which may contain up to 80% additive ingredients. Preferred embodiments of the invention may include silogel compositions which provide high viscosity/no separation due to API. They are not temperature-sensitive, have no shear stress from the ointment mill/EMP, have no gumming up/stickiness, and no hardening.
