Reactive Topical Skin Protectant
Abstract
Biopraxis is developing a method for production of novel catalysts from inexpensive precursors, at high yield, under mild conditions. Under an earlier program, Biopraxis demonstrated that catalysts produced by this method can effectively neutralize the agent simulants diisopropyl fluorophosphate (DFP) and 2-chioroethyl ethyl sulfide (CEES). Government testing identified a formulation that exhibited excellent efficacy against both GD and HE), reducing nerve agent penetration by 93.1% and mustard penetration by 81.5% in comparison with the not reactive TSP. Accordingly, the Government awarded a follow-on program. The program was cut short due to funds being diverted for the Iraq war. The best formulation that had been identified by that time did not allow any detectable GD penetration in 2Ohours (99.96% reduction) and was projected to take more than 950 hours to reach breakthrough (a 16,502% increase). This same formulation also showed excellent efficacy against HD; i.e., a 217% increase in the time to breakthrough, and a 59% reduction in penetration by 2Ohours, in comparison with the non-reactive TSP. Since the catalysts are solid particulates, formulations may contain mixtures of catalysts that are superior for decontaminating different agents.
