Justification:

Classification of Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene (CAS No 37330 -39 -5) for effects in the environment

In determining the classification appropriate to Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene , it is necessary to consider all available evidence concerning its persistence, potential to accumulate and predicted or observed environmental fate and behaviour that may present a long-term and/or delayed danger to the structure and/or functioning of aquatic ecosystems. These points are considered below. 

 

Persistence

Available data suggests that cardanol is readily bio-degradable in water and soil compartment of the environment. Thus, it can be expected that Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene  isclassified as a non-persistent (P) chemical. 

 

Potential to accumulate

The estimated bioconcentration factor (BCF) for cardanol is 483.6 L/kg w which does not exceed the bioconcentration threshold of 2000. Thus it is concluded that Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.

Thus, Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene  does not satisfy the criterion for classification as bioaccumulative (B).

Toxicity

 

The short term toxicity values of fish, invertebrates and algae are LC50 = 0.085 mg/L, EC50 = 0.42 mg/L and EC50 = 1.41 mg/L, respectively. These values suggest classification for aquatic toxicity in Acute category 1.

However, in accordance with Annex XIII of the REACH regulation, the criteria of the long-term no-observed effect concentration (NOEC) or EC10 for marine or freshwater organisms of less than 0,01 mg/l is not satisfied. Thus Reaction mass of Cardanol diene and Cardanol monoene and Cardanol triene shall not be considered a toxic chemical.

 

Thus, based on all the above it can be inferred that cardanol is neither a P substance nor will qualify as B and T(Toxic).Thus, the chemical is not a PBT (vPvB).
