The pattern of identified uses described for isoheptane includes short-term peak exposure by inhalation and the dermal route as well as long-term repeated exposure by inhalation and the dermal route. In the case of short-term exposure, it is not possible to derive a DNEL for systemic effects, since CNS toxicity (narcotic effects) and local irritation on the skin are the leading effects.Therefore, appropriate risk management measures will be identified.

The pattern of identified uses described for isohheptane includes short-term peak exposure by inhalation and the dermal route as well as long-term repeated exposure by inhalation and the dermal route. In the case of short-term exposure, it is not possible to derive a DNEL for systemic effects, since CNS toxicity (narcotic effects) and local irritation on the skin are the leading effects.Therefore, appropriate risk management measures will be identified.
The assessment factors used to derive the relevant DNELs were taken from ECETOC 2003 and other, more recent, information.
