Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

DNEL related information

Workers - Hazard for the eyes

Additional information - workers

The long-term DNELs are based on a subacute 28 day oral gavage study with isopropyl myristate. The subacute NOAEL for rats was found to be 1000 mg/kg bw/d (see section 7.5.1, Gloxhuber, 1982).

Assessment factors were used according to the "Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health", ECHA, May 2008.

Dermal DNEL:

QSAR based dermal permeability regarding molecular weight, log Pow and water solubility, calculated a very low dermal absorption for isopropyl myristate (see section 7.1.2, Danish EPA, 2010). Therefore, assuming a dermal absorption of 10% displays a sufficient conservative approach.

Inhalation DNEL worker:

The NAEC was determined by calculating from oral exposure to 8h inhalation exposure by factor 0.38 and allometric scaling from rat to human worker by factor 0.67 according to the "Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health", ECHA, May 2008.

Inhalation DNEL - general population:

The NAEC was determined by calculating from oral exposure to 8h inhalation and allometric scaling from rat to human worker by factor 1.15 according to the "Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health", ECHA, May 2008.
