- Justification:
Classification of 3-phenoxybenzylic alcohol for effects in the environment
In determining the classification appropriate to 3-phenoxybenzylic alcohol, it is necessary to consider all available evidence concerning its persistence, potential to accumulate and predicted or observed environmental fate and behavior 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
The half period of 3-phenoxybenzylic alcohol in water and soil is 15 days and 30 days therefore it is considered that the substance will qualify as not persistent as the half-life does not exceed the threshold criteria of 40 days and 120 days respectively. So, it can be indicated that the substance is readily biodegradable in water and soil medium also in sediment the half-life is 135 days and it can thus be inferred that the substance is non persistent in sediment medium as well. However, it can be observed that 3-phenoxybenzylic alcohol is not biodegradable in nature. But based on the half-life it can be inferred that 3-phenoxybenzylic alcohol is non persistent in character.
Thus, 3-phenoxybenzylic alcohol is not classified as a persistent (P) chemical.
Potential to accumulate
The potential for 3-phenoxybenzylic alcohol to bioaccumulate in the tissues of organisms that inhabit aquatic or terrestrial matrices is negligible as the BCF factor for the substance is less than 2000.
The estimated BCF of 3-phenoxybenzylic alcohol of 30 is below the threshold of 2000.
Thus, 3-phenoxybenzylic alcohol does not satisfy the criterion for classification as bio accumulative (B).
Potential to Toxicity
The toxicity values of fish, invertebrates and algae for the target chemical are LC50 = 4.303 mg/L, EC50 = 0.05 mg/L and EC50 = 13.498 mg/L, respectively. These values suggest that classification for aquatic toxicity due to this chemical will be applicable. But, the estimated BCF value of 3-phenoxybenzylic alcohol reported is not >= 500 though the chemical is found to be not readily degradable in the aquatic environment. Thus considering the CLP Criteria for aquatic classification of the substance, it is concluded that 3-phenoxybenzylic alcohol is likely to exhibit aquatic toxicity in acute and chronic category 1.
Thus, 3-phenoxybenzylic alcohol satisfy the environmental effect criterion for classification as toxic (T).
It can be inferred that 3-phenoxybenzylic alcohol is a not a PBT (including vPvB) substance as per Annex XIII of the REACH Regulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
