Conclusion on classification
Classification related key information
Biodegradation in water: readily biodegradable; WoE, read across
BCF: 255 L/kg in fish after 28 days exposure (OECD 305); read across

Acute toxicity:
- to fish: no effects expected up to the limit of water solubility; read across
- to invertebrates: no effects expected up to the limit of water solubility; WoE, read across
- to algae: no effects expected up to the limit of water solubility; WoE, read across
Chronic toxicity:
- to fish: no effects expected up to the limit of water solubility; WoE, read across
- to invertebrates: no data available
- to algae: no effects expected up to the limit of water solubility; WoE, read across
Classification justification according to CLP
Fatty acids, C18-22 (CAS 90990-11-7) is poorly water soluble. Based on a weight of evidence (WoE) determination, the substance is considered to have no acute and chronic effects on aquatic organisms up to the limit of its water solubility, is readily biodegradable under environmental conditions and has low potential for bioaccumulation. Hence, Fatty acids, C18-22 (CAS 90990-11-7) does not need to be classified and labelled as environmental hazard according to the 2nd ATP of Regulation (EC) No.1272/2008 (CLP).
Classification justification according to DSD
Fatty acids, C18-22 (CAS 90990-11-7) is poorly water soluble. Based on a weight of evidence (WoE) determination, the substance is considered to have no acute effects on aquatic organisms up to the limit of its water solubility, is readily biodegradable and has a low potential for bioaccumulation under environmental condition. Hence, Fatty acids, C18-22 (CAS 90990-11-7) does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
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.
