The invention provides compounds of Formula (I), or pharmaceutically acceptable salts thereof. The compounds, compositions, methods and kits of the invention are useful for the treatment of pain, itch, and neurogenic inflammation.

Processes and facilities for producing several types of recycled content organic chemical compounds from waste plastic. Processing schemes are described herein for converting waste plastic (or hydrocarbon having recycled content derived from waste plastic) into useful intermediate chemicals and final products. In some aspects, recycled content aromatics (r-aromatics) can be processed to provide recycled content benzene (r-benzene) and/or recycled content toluene (r-toluene), which can be further processed to form a variety of intermediate and final organic chemical compounds including, but not limited to, recycled content nylons, recycled content polystyrene. recycled content benzoic acid, and recycled content phenol.
