PBT assessment: overall result

Reference
Name:
Alcohols, C13-15-branched and linear
Type of composition:
legal entity composition of the substance
State / form:
liquid
Reference substance:
Composition 1
Reference substance:
Composition 1
Reference substance:
Composition 1
PBT status:
the substance is not PBT / vPvB
Justification:

PERSISTENCE

The substance is readily biodegradable and may therefore be considered to be “not P/vP”.

BIOACCUMULATION

The substance has a log Kow of ≥4.5. As no experimentally determined BCF is available, the substance must be assessed as “vB (and B)” based on the log Kow alone. However, the substance is considered unlikely to be B/vB as its different C13 and C15 components are rapidly degradable and long-chain alcohols are generally known to be very efficiently biotransformed. Estimated BCF values range from ca. 500 to 1000 L/kg based on a QSAR that takes into account biotransformation (Arnot-Gobas).

TOXICITY

For the substance a long-term 72-h EC10 value of 0.012 mg/L was determined in aquatic algae. Further, there is no evidence of CMR properties or chronic toxicity as specified in REACH Annex XIII. Therefore, the substance is assessed to be “not T”.
