Title: Frank S. Rankin: Innovator in Pharmaceutical Delivery Devices

Introduction

Frank S. Rankin is a notable inventor based in Swansea, GB. He has made significant contributions to the field of pharmaceutical delivery devices, holding a total of 2 patents. His work focuses on improving the efficiency and effectiveness of drug delivery systems.

Latest Patents

One of Rankin's latest patents is for a pharmaceutical delivery device that utilizes a siloxane polymer matrix. This innovative device is designed to deliver both hydrophilic and hydrophobic pharmaceutically active materials. The device features small particles with an average diameter of less than 20 microns, which comprise the hydrophilic or polar pharmaceutically active material dispersed in a silicone matrix. The production of these devices involves the use of specific organopolysiloxane-polyoxyalkylene copolymers, and an emulsion of the drug component is created before curing the composition into an elastomer.

Another significant patent by Rankin involves a treatment composition for keratinous fibers. This composition includes a polydiorganosiloxane with a molecular weight of at least 2500 and terminal --OX groups, where X can be hydrogen, lower alkyl, or alkoxyalkyl. The formulation also contains an organosiloxane with at least three silicon-bonded hydrogen atoms. This composition is particularly effective in rendering fibers shrink-resistant and is ideally applied in the form of an aqueous emulsion.
