Additional information

Justification for selection of repeated dose toxicity via oral route - systemic effects endpoint:

Data is from a long term study (2 years) wherein the TDLo was found to be greater than 120000 mg/kg body weight in humans

Justification for selection of repeated dose toxicity inhalation - systemic effects endpoint:

The low vapour pressure of the chemical diiodohydroxyquinoline shall ensure that the exposure to vapours shall be negliglible and therefore it is expected that the chemical shall not exhibit repeated dose toxicity by the inhalation route.

Justification for selection of repeated dose toxicity dermal - systemic effects endpoint:

From the acute dermal study results and also considering the fact that the chemical diiodohydroxyquinoline is used as a skin antiseptic it is assumed that the chemical shall not exhibit repeated dose toxicity by the dermal route in low concentrations.

Justification for classification or non-classification

The data for repeated dose toxicity by the oral route is from a long term study (2 years) wherein the TDLo was found to be greater than 120000 mg/kg body weight in humans. Given that the oral route of exposure is considered to be the most prominent route of exposure, it is concluded that the chemical shall not exhibit repeated dose toxicity via the oral, inhalation and dermal route.
