Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Workers - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
1.76 mg/m³
Most sensitive endpoint:
developmental toxicity / teratogenicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
75
Dose descriptor starting point:
NOAEL
Value:
150 mg/kg bw/day
Modified dose descriptor starting point:
NOAEC
Value:
132.24 mg/m³
Explanation for the modification of the dose descriptor starting point:
The results of the oral combined repeated toxicity/reproscreening study with Standolized Linseed Oil are read across to Standolized Soybean Oil. The oral NOAEL for developmental toxicity of 150 mg/kg was used to base the inhalation DNEL on. Route-to-route extrapolation is applied in accordance with the ECHA REACH Guidance on Information Requirements R.8 by dividing by the 8-hr respiratory volume of the rat (0.38 m3/kg bw), and corrected for light activity of the worker (6.7 m3/ 10 m3). The derived concentration is corrected for differences in oral and inhalation absorption with a default factor of 2, in accordance with the ECHA REACH Guidance, arriving at a NOAEC worker of 132.24 mg/m3.
AF for dose response relationship:
1
Justification:
Default assessment factor as a NOAEL is used
AF for differences in duration of exposure:
6
Justification:
Default assessment factor for duration of exposure (sub-acute to chronic)
AF for interspecies differences (allometric scaling):
1
Justification:
Not necessary as allometric scaling is taken into account in the route to route extrapolation
AF for other interspecies differences:
2.5
Justification:
Default assessment factor for other interspecies differences
AF for intraspecies differences:
5
Justification:
Default assessment factor for intraspecies differences workers
AF for the quality of the whole database:
1
Justification:
Study was a reliable OECD 421 study under GLP-conditions with structural similar substance Standolized Linseed OIl. It is not deemed necessary to apply an extra assessment factor for read across purposes as due to higher level of polyunsaturated fatty acid chains, Standolized Linseed Oil presents the worst case scenario in terms of toxicology.
AF for remaining uncertainties:

Justification:
No remaining uncertainties were identified

Explanation for the modification of the dose descriptor starting point:
The results of the oral combined repeated toxicity/reproscreening study with Standolized Linseed Oil are read across to Standolized Soybean Oil. The oral NOAEL for developmental toxicity of 150 mg/kg was used to base the dermal DNEL on. Route-to-route extrapolation is applied in accordance with the ECHA REACH Guidance on Information Requirements R.8 by correcting for 10% dermal absorption

Dose descriptor starting point:
NOAEL
Value:
150 mg/kg bw/day
Modified dose descriptor starting point:
NOAEC
Value:
65.22 mg/m³
Explanation for the modification of the dose descriptor starting point:
The results of the oral combined repeated toxicity/reproscreening study with Standolized Linseed Oil are read across to Standolized Soybean Oil. The oral NOAEL for developmental toxicity of 150 mg/kg was used to base the inhalation DNEL on. Route-to-route extrapolation is applied in accordance with ECHA’s Guidance R.8 (November, 2012). In the route to route extrapolation via the inhalation route a correction for respiratory volume is applied by using 1.15 m3/kg bw (ECHA’s guidance R.8, November, 2012). The derived concentration is corrected for differences in oral and inhalation absorption with a default factor of 2, in accordance with the ECHA REACH Guidance, arriving at a NOAEC general population of 65.22 mg/m3.
