Abstract

A topical skin protectant formulation containing a barrier cream and an active moiety for protecting warfighters and civilians against all types of harmful chemicals, specifically chemical warfare agents (CWA). The active moiety is an amine, polyalkenimines and/or derivatives. The topical skin protectant offers a barrier property and an active moiety that serves to neutralize chemical warfare agents into less toxic agents.
