Acute toxicity
A DNEL for acute toxicity should be derived if an acute hazard leading to acute toxicity (e.g. C&L) has been identified and there is a potential for high peak exposures. These “peaks” are normally associated with inhalation exposure but are less common for skin contact and ingestion (Appendix R.8-8). Isodecyl benzoate is not classified for acute toxicity; oral, dermal or inhalation.
Irritation
Isodecyl benzoate is not classified as a skin irritant. A DNEL is not required for this endpoint.
Sensitization
Isodecyl benzoate is not classified as a sensitizer. A DNEL is not required for this endpoint.
Genetic toxicity
Isodecyl benzoate is not classified as a genotoxic or mutagenic. A DNEL is not required for this endpoint.
Reproductive and Developmental toxicity
Isodecyl benzoate is not classified as a reproductive or developmental toxin. A DNEL is not required for this endpoint.
Long-term systemic effects
The potential of a substance to cause long-term systemic effects can judged based on the results of repeated dose toxicity testing. The following DNELs are conservative by nature and are protective of all adverse effects.
Dermal - Systemic
Dose descriptor = NOAEL of 619 mg/kg/day; from a well described repeated dose oral study.
Modification of dose descriptor
= dermal NOAEL * (animal exposure / worker exposure) * (animal days / worker days) * (oral abs / dermal abs)
= 619 * (8 / 8) * (4 / 5) * (100/10)
dermal NOAEL = 4952 mg/kg/day
