Environmental impact of pharmaceuticals and personal care products mechanism occurs: (CH)2CO + hv → CH + CHCO CHCO → CH+ CO CH+ (CH)2CO → CH4 + CH2COCH 2CH → C2H6 A second pathway that nail polish remover can enter in the atmosphere is reacting with hydroxyl radicals. When acetone reacts with hydroxyl radicals, its main product is methylglyoxal. Methylglyoxal is an organic compound that is a by-product of many metabolic pathways. It is an intermediate precursor for many advanced glycation end-products, that are formed for diseases such as diabetes or neurodegenerative diseases. The following reaction occurs: (CH)2CO + ·OH → CHC(O)OH + ·CH CHC(O)OH + ·CH→ CHC(O)COH +
