Another component is furanocoumarin, which induces phototoxicity in skin
Alternatively, the second, cationic structural unit can be derived from a [2-(methacryloylamino) ethyl] tri-methylammonium salt, such as, for example, [2-(methacryloylamino) ethyl] tr-methylammonium chloride, [2-(methacryloylamino) ethyl] tri-methylammonium fluoride, [2 (methacryloylamino) ethyl] tri-methylammonium bromide, [2-(methacryloylamino) ethyl] tri-methylammonium iodine, [2-methacryloylamino) ethyl] tri-methylammonium bisulfate, [-(methacryloylamino) ethyl] tri-methylammonium alkyl sulfat, [2-(methacryloylamino) ethyl] tri-methylammonium dihydrogen phosphate, [2-(methacryloylamino) ethyl] tri-methylammonium hydrogen alkyl phosphate, [2 (methacryloylamino) ethyl] tri-methylammonium dialkyl phosphate, and combinations thereof
Why TB-500 Might Be Better" TB-500 is arguably the superior compound for pure structural damage
Why we dont recommend most DIY tests Though we think DIY lead tests are worthwhile, we didnt like the more comprehensive (and more expensive) DIY kits that we tested, and we recommend against using any of them
