Conclusion on classification
Classification related key information
Degradation:
Biodegradation: readily biodegradable according to category approach
Bioaccumulation:
Bioaccumulation in fish: BCF (28d)= 255 L/kg (OECD 305 E); read across
Aquatic acute toxicity:
- Fish: LC50 (96 h) > 5 mg/L for Oryzias latipes (nominal, OECD 203); no effects observed up to the limit of water solubility
- Invertebrates: EC50 (48h) > 5 mg/L for Daphnia magna (nominal, OECD 202): no effects observed up to the limit of water solubility
- Algae: ErC50 (72 h) > 5 mg/L for Selenastrum capricornutum (nominal, OECD 201); no effects observed up to the limit of water solubility
Aquatic chronic toxicity:
- Fish: NOEC (28 d): 2 mg/L for Danio rerio (OECD 305 E), read across: no effects up to the limit of water solubility
- Invertebrates: NOEC (21 d)≥ 0.84 mg/L (meas. TWA) for Daphnia magna (OECD 211); no effects observed up to the limit of solubility
- Algae: NOErC (72 h) ≥5 mg/L for Selenastrum capricornutum (nominal, OECD 201); no effects observed up to the limit of water solubility
Classification justification according to CLP
Docosanoic acid (CAS 112-85-6) is a poorly water soluble substance, for which no acute and chronic toxicities were observed up to the limit of water solubility (0.016 mg/L) for fish, invertebrates and algae. Based on the category approach, the substance is considered to have low potential for bioaccumulation and is judged as readily biodegradable. Hence, docosanoic acid does not need to be classified and labelled as environmental hazard according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
