Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information - workers

The pattern of identified uses described for Normal-Heptane 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.

Additional information - General Population

The pattern of identified uses described for heptane 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.
