- Reference substance:
- di-, tri- and tetrachlorotetradecane
- Reference substance:
- di-, tri- and tetrachlorotetradecane
- Reference substance:
- di-, tri- and tetrachlorotetradecane
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence
A GLP study with only minor deviations from OECD Guideline 301 D was conducted. C14 chlorinated paraffin (45% chlorination) was found to be rapidly biodegraded (64% degradation over 28 days) in closed bottle test (van Ginkel, 2010a).
The substance is regarded as readily biodegradable indicating the substance is not persistant.
Bioaccumulation
The log Kow value was determined to be > 4.5 indicating the substance might be bioaccumulative.
Do to lack of higher tier data the susbtance can be regarded as being bioaccumulative.
Toxicity
A short-term EC50 in Daphnia magna of C14-17 chlorinated paraffin (52% chlorinated) gave an EC50 of 0.0059 mg/L.In a reliable test, conducted according to OECD Guideline 202, a long-term NOEC in Daphnia magna of 0.01 mg/L has been reported for a C14-17 chlorinated paraffin (52% chlorinated). Note result is at the cut off for toxicity criterion.
Together, the results are considered to meet the criterion for toxicity (e.g. EC50 and NOEC < 0.01 mg/L) under Annex XIII.
Reference
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
