PBT assessment: overall result

Reference
Name:
Lexolube1
Type of composition:
legal entity composition of the substance
State / form:
liquid
Reference substance:
Lexolube1
PBT status:
the substance is not PBT / vPvB
Justification:

Criteria for assessing PBT properties are defined in Annex XIII, REACH Regulation (EC) No 1907/2006. Further details are laid down in ECHA Guidance on Information Requirements and Chemical Safety Assessment; Chapter R.11: PBT Assessment (Nov 2014). The assessment of PBT / vPvB properties is based upon a separate assessment for each parameter (i.e. P or vP, B or B and T). Substances are only assigned as PBT or vPvB when they fulfil the criteria for all three properties (persistency, bioaccumulation and toxicity in case of PBT substance) or both criteria (i.e. very persistent and very bioaccumulative) in case of vPvB, respectively.

Available data indicate that the substance does not meet the requirements for B and T classification. Even though the substance is not readily biodegradable (possibly P) degradation does occur. Modelling of possible degradation pathways does indicate that ultimate degradation is feasible, predicting likely degradation products that are known to be readily biodegradable.

Therefore, making all allowances for regulatory parameters available, the substance is neither PBT nor vPvB.

Likely routes of exposure:

Workers may be exposed via the dermal route due to substance handling during manufacture. This exposure is negligible as the absorption through the skin is nearly zero. Based on the low vapour pressure of the substance, an uptake via the inhalative route is not relevant, too. Oral exposure is not relevant based on the handling, education and safety precautions in the factory. As conclusion, only the dermal exposure route may be relevant for humans, but is negligible.
