Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence Assessment
A substance is not considered to be persistent if it can be demonstrated that it has potential to degrade (via photolysis, hydrolysis and/or biodegradation). The substance Acacia mearnsi extract was found to be readily biodegradable in an OECD 301B and OECD 301D with 100% degradation respectively in 20 and 28 days. Therefore, based on initial persistence screening Acacia mearnsi extract is not expected to meet the Persistent (P) or very Persistent (vP) criteria.
Bioaccumulation Assessment
The study (Klimish 1, GLP laboratory) concerning the estimatation of the partition coefficient n-octanol/water (Kow) with HPLC method (OECD guideline 117) showed a log Kow less than 3, potential for bioaccumulation is thus low. Therefore Acacia mearnsi extract is neither Bioaccumulative (B) nor very Bioaccumulative (vB).
Toxicity Assessment
Substance does not meet screening criteria. Acute aquatic toxicity (LC50 and EC50) >0.1mg/l. Substance is neither carcinogenic, mutagenic nor teratogenic. Therefore Substance is not Toxic (T).
Summary and overall Conclusions on PBT or vPvB Properties
Substance does not meet the screening criteria for persistency nor toxicity so is neither PBT nor vPvB.
- Likely routes of exposure:
The substance is not PBT / vPvB
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
