Abstract: There is provided a decontaminant product for decontaminating a surface or object that is contaminated, or suspected to be contaminated, with a hazardous chemical agent, wherein the decontaminant product comprises polymeric material comprising a polymer of: (i) itaconic acid, or a derivative thereof such as an itaconic ester or an itaconic acid isomer; (ii) an acrylate monomer, such as 2-trifluoromethyl acrylic acid (TFMAA), methacrylic acid (MA), N,N-methylene bisacrylamide (MBA) 2-hydroxyethyl methacrylate, N,N-diethylamino ethyl methacrylate (DEAEM), acrylamido-2-methyl-1-propanesulfonic acid (AMPSA), ethylene glycol dimethacrylate (EGDMA), acrylic acid, acrylamide, acrylonitrile and acrolein, or a derivative thereof; (iii) urocanic acid, or a derivative thereof such as an ester thereof such as urocanic acid ethyl ester; (iv) a vinyl monomer, such as 1-Vinylimidazole, p-divinylbenzene, m-divinylbenzene, 2-Vinylpyridine and 4-Vinylpyridine; or (v) an amine monomer such as allylamine.

Abstract: A skin sample is mounted in a diffusion cell between a receptor and a donor chamber. A substance to be tested is provided to the skin sample via the donor chamber. The diffusion cell has a driver for applying pressure variations to fluid in the receptor chamber in order to cause repeated flexing of the skin sample to simulate the behaviour of living (moving) skin.
