Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

Derivation of PNEC is not relevant because this product is used in STP and is 100% readily biodegradable. However, some PNEC for aquatic part were estimated.

Conclusion on classification

The results from the aqutic toxicity studies are as follows:

LC50 (96h) fish (freshwater, mortality) = 67.1 mg/L (estimated concentration) with 95% confidence limits 54.0 - 83.0 mg/L

EC50 (48h) daphnia (freshwater, mortality) = 13.2 mg/L (estimated concentration) with 95% confidence limits 7.0 - 25.0 mg/L

EC50 (72h) alga (saltwater, biomass) = 7.4 mg/L

EC50 (96h) alga (freshwater, growth rate) = 12.8 mg/L (estimated concentration) with 95% confidence limits 9.5 - 23.6 mg/L

EC50 microorganism was not dtermined because the tested substance is readily biodegradable (100%).

The test substance is readily biodegradable (100%), no potential for bioaccumulation were showed therefore according to all the above available data, Acacia mearnsi extract does not require any classification for the environmental part under the 1272/2008/EC regulation (and Directive 67/548/EEC).

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.
