Important substitute for phthalates

Due to the increased regulation of phthalates, Hexamoll® DINCH® has been used as a plasticizer since 2002, mainly as a DEHP (di (2-ethylhexyl) phthalate) substitute in toys and medical equipment. Due to its similar structure (the aromatic ring of the phthalates is replaced by a cyclohexane ring) it possesses similar physical properties but shows far lower toxicity. The high demand for phthalate species leads to a strong increase in the use and production of DINCH®.


MINCH Cyclohexane-1,2-dicarboxylate-mono-4-methyloctyl ester is the primary metabolite of DINCH® after elimination of an ester rest.
OH-MINCH Cyclohexane-1,2-dicarboxylate-mono-(7-hydroxy-4-methyl)octyl ester is a secondary metabolite of DINCH®.
oxo-MINCH Cyclohexane-1,2-dicarboxylate-mono(oxo-isononyl) ester is a secondary metabolite of DINCH®.
cx-MINCH Cyclohexane-1,2-dicarboxylate-mono-(7-carboxylate-4-methyl) heptylester is a secondary metabolite of DINCH®.
