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 +
Solvent casting and particulate leaching Solvent casting and particulate leaching In solvent casting and particulate leaching (SCPL), a polymer is dissolved in an organic solvent. Particles, mainly salts, with specific dimensions are then added to the solution. The mixture is shaped into its final geometry. For example, it can be cast onto a glass plate to produce a membrane or in a three-dimensional mold to produce a scaffold. When the solvent evaporates, it creates a structure of composite material consisting of the particles together with the polymer. The composite material is then placed in a bath which dissolves the particles, leaving behind a porous structure.
