Toxicity of Hexamoll® DINCH® following intravenous administration

TL;DRAbstract

Alternative plasticizers to di(2-ethylhexyl) phthalate (DEHP) for blood bags have been sought for many years. Cyclohexane-1,2-dicarboxylic acid, diisononylester (Hexamoll(®) DINCH(®)) is an alternative that has been evaluated in preliminary studies for compatibility and efficacy to preserve whole blood. While Hexamoll(®) DINCH(®) has an extensive database for mammalian toxicity via oral administration, data were needed to evaluate toxicity from intravenous (IV) administration to support the use of the plasticizer Hexamoll(®) DINCH(®) in blood bags. A series of studies was performed by slow IV injection or IV infusion of Hexamoll(®) DINCH(®), a highly viscous, hydrophobic substance, suspended in Intralipid(®) 20% (20% intravenous fat emulsion). Rats were injected once, followed by 14 days of recovery; injected daily for 5 days followed by 5 days of recovery, or infused for 29 days (4h/day) followed by 14 days of recovery. Dose levels were 0, 62, 125, and 250-300mg/kg body weight/day. Th
