- Conclusions:
- The test substance - a UVCB - has a low water solubility (0.035 mg/L), which is not favorable for absorption. The partition coefficient of 5.14 is also indicative of low absorption after oral intake. Based on these physico-chemical properties it is therefore unlikely that the substance will show a high systemic exposure after oral administration.
The test substance has been administered orally to rats for at least 4 weeks in an OECD 422. Systemic effects were observed at the mid and high dose levels, demonstrating a clear absorption of the substance upon oral administration. Based on this experimental data and as a worst case approach, the oral absorption is considered at 100% for risk assessment purposes.
In the gastro-intestinal tract, the test substance may be metabolized. Excretion will occur mainly via urine (low molecular weight products) or bile (high molecular weight products). Based on the partition coefficient, the test substance may accumulate to some extent in adipose tissue.
The test substance is a waxy solid, with a low vapour pressure (0.0001 Pa) and high boiling temperature (> 250°C, degradation). Based on these characteristics, the substance is not expected to enter the respiratory tract and subsequent absorption of the test substance via inhalation is considered negligible.
According to the criteria given in the REACH guidance, 10% dermal absorption will be considered in case MW > 500 and log Pow <(-1) or > 4, otherwise 100% dermal absorption should be used. As the criteria for 10% dermal absorption are not met, 100% dermal absorption should be considered for risk assessment purposes. - Executive summary:
Oral and dermal absorption are estimated at 100% while absorption via inhalation is negligible.
