Workers - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
5 mg/m³
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
18
Dose descriptor starting point:
NOAEL
Value:
103 mg/kg bw/day
Modified dose descriptor starting point:
NOAEC
Value:
91 mg/m³
Explanation for the modification of the dose descriptor starting point:

Starting point us the oral NOAEL of 103 mg/kg bw. A factor of 2 is applied for route to route extrapolation: oral to inhalation. For animal versus human exposure the following formula is applied: 103/2*(1/0.38)*6.7/10) = 91 mg/m3.

AF for dose response relationship:
1
Justification:
No additional assessment factor for dose response is needed because the dosing was well spaced in the study and a NOAEL in the 8-k study was assessed by EFSA (ECHA’s guidance, R.8.4.3.1, November, 2012)
AF for differences in duration of exposure:
6
Justification:
Since the dose descriptor is derived is from an 8 wk study an additional assessment factor of 6 is used to take the extrapolation of sub-acute data to chronic exposure into account (ECHA 2012, Chapter R8, p 29)
AF for interspecies differences (allometric scaling):
1
Justification:
An assessment factor of 1 has been used because the difference in metabolic rate between rat and humans has been accounted for in the conversion of NOAEL in mg/kg bw to the NOEC mg/m3, as presented in ECHA’s guidance R.8, figure R. 8-2 (November, 2012
AF for other interspecies differences:
1
Justification:
Additional assessment factors for interspecies differences are not needed as has been derived in the ECETOC report (TR 110, 2010) based on a review of the scientific literature. The concept of adjusting animal dose by allometric scaling predicts reasonably well the appropriate dose in humans. A Geometric Standard Deviation (GSD) of 2.5-2.6 suggests the likelihood of some variability or additional uncertainty around the predicted NOAEL in humans. This analysis is based on a comparison of animal to actual human data that per se includes intraspecies variability in humans (see below at intraspecies differences).
AF for intraspecies differences:
3
Justification:
An assessment factor of 3 has been used to account for the intraspecies differences. This factor has been retrieved by ECETOC (TR110, 2010). The ECETOC analysis has been based on a comparison between animal and actual human data that per se includes intraspecies variability in humans. In addition, the human population under investigation comprised cancer patients; this represents a very sensitive subpopulation. A Geometric Standard Deviation (GSD) of 2.5-2.6 suggests the likelihood of some variability or additional uncertainty around the predicted NOAEL in humans. Thus, this standard deviation represented by the GSD of 2.5-2.6 is probably due to potential differences in biological sensitivity between species, and includes intraspecies differences
AF for the quality of the whole database:
1
Justification:
An assessment factor of 1 is applicable because the information fulfils the REACH requirements: The repeated dose effect of the key toxicant is used: Camphor, which information was assessed by EFSA. This substance has been tested in an 8-wk study and a sub-acute NOAEL is derived. For the other constituents of Terpene hydrocarbon alcohols read across from Terpineol-multi is used, which is a major constituent of the substance. For Terpineol multi sub-chronic inhalation information is available (OECD TG 413, Rel. 1) resulting in absence of adverse effects. This means that using the NOAEL of Camphor is conservative for the Terpene hydrocarbon alcohols and no additional AF for the quality of the database is needed) ECHA’s Guidance, R.8.4.3.1, November, 2012)
AF for remaining uncertainties:
1
Justification:
There are no remaining uncertainties other than those addressed above.

Overall assessment factor (AF):
72
Dose descriptor starting point:
NOAEL
Value:
103 mg/kg bw/day
Modified dose descriptor starting point:
NOAEL
Value:
1.43 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:

Based on the toxico-kinetic information it can be anticipated that dermal absorption equals or is lower than oral absorption and will not exceed oral absorption. Therefore the starting dose descriptor is the same: 103 mg/kg bw.

AF for dose response relationship:
1
Justification:
No additional assessment factor for dose response is needed because the dosing was well spaced in the 8-wk study and a NOAEL was assessed by EFSA (ECHA’s guidance, R.8.4.3.1, November, 2012).
AF for differences in duration of exposure:
6
Justification:
Since the dose descriptor is derived from an 8-wk study an additional assessment factor of 6 to take account of extrapolation of sub-acute data to chronic exposure (ECHA 2012, Chapter R8, p 29).
AF for interspecies differences (allometric scaling):
4
Justification:
For allometric scaling a factor of 4 is applicable to convert rat to human data, as determined by ECHA (Table R.8-3, 2012)
AF for other interspecies differences:
1
Justification:
Additional assessment factors for interspecies differences are not needed as has been derived in the ECETOC report (TR 110, 2010) based on a review of the scientific literature. The concept of adjusting animal dose by allometric scaling predicts reasonably well the appropriate dose in humans. A Geometric Standard Deviation (GSD) of 2.5-2.6 suggests the likelihood of some variability or additional uncertainty around the predicted NOAEL in humans. This analysis is based on a comparison of animal to actual human data that per se includes intraspecies variability in humans (see below at intraspecies differences).

AF for the quality of the whole database:
1
Justification:
An assessment factor of 1 is applicable because the information fulfils the REACH requirements: The repeated dose effect of the key toxicant is used: Camphor, which information was assessed by EFSA. This substance has been tested in an 8-wk study and a sub-acute NOAEL is derived. For the other constituents of Terpene hydrocarbon alcohols read across from Terpineol-multi is used, which is a major constituent of the substance.

AF for remaining uncertainties:
1
Justification:
There or no remaining uncertainties, other than those that are already addressed above.
Acute/short term exposure

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
833 µg/cm²
Most sensitive endpoint:
sensitisation (skin)
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
3
Dose descriptor:
NOAEC
Value:
2 500 µg/m³
AF for dose response relationship:
1
Justification:
The NOAEC is used in the LLNA study (10%) was taken as the dose descriptor starting point and therefore an AF of dose response is not needed. In addition, the concentration were well spaced and a linear relation between concentration and effects was derived which is in accordance with ECHA’s guidance, R.8.4.3.1, November, 2012.
AF for differences in duration of exposure:
1
Justification:
An AF for difference in exposure is not needed because the LLNA represents also repeated exposure as is applicable for human exposure.
AF for interspecies differences (allometric scaling):
1
Justification:
An assessment factor for allometric scaling is not needed since local effects are independent of the basal metabolic rate and therefore this scaling is not applied (allometric scaling factor of 1) ECHA, 2012, Chapter R8.
AF for other interspecies differences:
1
Justification:
The assessment factor for remaining uncertainties can be 1. For vehicle effects: an assessment factor of 1 is applied as the matrices of the products compiled from the substance are not intended to enhance penetration. For type of skin (skin thickness and skin integrity) it can be seen that the human skin (exposed hands) to be similarly or less sensitive compared to the skin of the mouse ear. The LLNA is selected as a model because the mouse ear is considered very thin with high blood flow and as such reflect a similar thickness and integrity compared to human skin in general.
AF for intraspecies differences:
3
Justification:
The intraspecies variation in humans is greater than that in the more homogenous experimental animal population. Based on an evaluation of the scientific literature by ECETOC, an AF of 3 for workers is advised after a detailed review of the literature. The ECETOC review is based on systemic effect. Sensitisation results from systemic exposure and therefore these ECETOC AFs can be applied here.
AF for the quality of the whole database:
1
Justification:
An assessment factor of 1 is applicable because the skin sensitisation LLNA information of Limonene is used which represents at maximum 15% of the Terpene hydrocarbon alcohols, of which 40-90% do not have skin sensitsation potential.
AF for remaining uncertainties:
1
Justification:
No remaining uncertainties were identified other than those already addressed above.
Acute/short term exposure

Additional information - workers

The DNELs for long term exposure (systemic effects) were derived in accordance with the Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.8: Characterisation of dose [concentration]-response for human health with the exception of two assessment factors:

1.        Interspecies differences, remaining differences. For remaining differences it is considered that those already have been taken into account when applying an assessment factor for allometric scaling. The argumentation for this can be found in the ECETOC Guidance on Assessment Factors to Derive a DNEL (Technical Report No. 110, 2010). It is concluded that the concept of adjusting animal dose by allometric scaling predicts reasonably well the appropriate dose in humans. A Geometric Standard Deviation (GSD) of 2.5-2.6 suggests the likelihood of some variability or additional uncertainty around the predicted NOAEL in humans. This analysis is based on a comparison of animal to actual human data that per se includes intraspecies variability in humans. As the human population under investigation comprised cancer patients, this represents a very sensitive subpopulation. Thus, this additional’ variability represented by the GSD of 2.5-2.6 is probably due to not only potential differences in biological sensitivity between species, but also intraspecies differences. The intraspecies variability in humans is taken into account by the specific Assessment Factors for workers (3) and the general population (5). The introduction of the ‘remaining’ AF of 2.5 for interspecies variability would therefore mean an unjustified compilation of AF. Therefore, although ‘residual’ interspecies variability may remain following allometric scaling, this is largely accounted for in the default AF proposed for intraspecies variability, i.e. reflecting the interdependency of inter- and intraspecies AF.

2.        Intraspecies differences. The current proposed AF for intraspecies extrapolation of systemic effects for workers and the general population in the ECHA guidance differ from those proposed in the ECETOC guidance (2010). After studying both guidances it is concluded that the AF proposed by ECETOC are based on an evaluation of the scientific literature while the REACH TGD refers to standard default procedures. Therefore, the ECETOC guideline will be followed until the scientific basis for using an alternative approach has been established. This means that for workers instead of an AF of 5 as proposed in the ECHA guidance an AF of 3 will be used and for the general population instead of an AF of 10 and AF of 5.

General Population - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
1.5 mg/m³
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
30
Dose descriptor starting point:
NOAEL
Value:
103 mg/kg bw/day
Modified dose descriptor starting point:
NOAEC
Value:
45 mg/m³
Explanation for the modification of the dose descriptor starting point:

Starting point is the NOAEL of 103 mg/kg bw. A factor of 2 is applied for route-to-route extrapolation: 50% oral to 100% inhalation absorption, resulting in a starting point of 51.5 mg/kg bw. In addition, for rat to human extrapolation a factor of 1.15 is used resulting in 45 mg/m3 (103mg/kg bw *0.5 (oral versus inhalation absorption /1(.15 (conversion from rat to human).

AF for dose response relationship:
6
Justification:
No additional assessment factor for dose response is needed because the dosing was well spaced in the study and a NOAEL is derived from an oral 8-wk study, assessed by EFSA (ECHA’s guidance, R.8.4.3.1, November, 2012).
AF for differences in duration of exposure:
6
Justification:
Since the dose descriptor is derived from 8-wk study an additional assessment factor of 6 to take account of extrapolation of sub-acute data to chronic exposure (ECHA 2012, Chapter R8, p 29).
AF for interspecies differences (allometric scaling):
1
Justification:
An assessment factor of 1 has been used because the difference in metabolic rate between rat and humans has been accounted for in the conversion of NOAEL in mg/kg bw to the NOAEC in mg/m3, as presented in ECHA’s guidance R.8, figure R. 8-2 (November, 2012).
AF for other interspecies differences:
1
Justification:
An assessment factor of 1 has been applied because besides allometric differences no other interspecies differences need to be accounted for which has been shown by ECETOC TR 110 (2010) after a review of the scientific literature. ECETOC concludes that adjusting animal dose by allometric scaling predicts reasonably well the appropriate dose in humans. The application the ‘remaining’ AF of 2.5 for interspecies variability would mean an unjustified compilation of AF. The ‘residual’ interspecies variability may remain following allometric scaling, but this is largely accounted for in the default AF proposed for intraspecies variability, i.e. reflecting the interdependency of inter- and intraspecies AF.
AF for intraspecies differences:
3
Justification:
An assessment factor of 5 has been used to account for the intraspecies differences as has been derived by ECETOC (TR110, 2010) based on a review of the scientific literature. The ECETOC analysis has been based on a comparison between animal and actual human data that per se includes intraspecies variability in humans. In addition, the human population under investigation comprised cancer patients, this represents a very sensitive subpopulation. A Geometric Standard Deviation (GSD) of 2.5-2.6 suggests the likelihood of some variability or additional uncertainty around the predicted NOAEL in humans. Thus, this standard deviation represented by the GSD of 2.5-2.6 is probably due to potential differences in biological sensitivity between species, but includes intraspecies differences.

Value:
103 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:

A modification of the dose descriptor is not needed because the oral route in the 8-wk toxicity study is used and the human exposure is also via the oral route. The starting point NOAEL is therefore 103 mg/kg bw.

AF for dose response relationship:
1
Justification:
No additional assessment factor for dose response is needed because the dosing was well spaced in the study and a NOAEL in the 8wk repeated dose toxicity study and assessed by EFSA (ECHA’s guidance, R.8.4.3.1, November, 2012)
