Additional information
Conclusion on classification
Studies investigating the short-term aquatic toxicity of 1,3-Propanediol, 2,2-bis(hydroxymethyl)-, allyl ether are available for freshwater fish, Daphnia and algae, showing L(E)C50 values of 52 mg/L (fish, 96-h LC50), 69.9 mg/L (Daphnia, 48-h EC50) and >100 mg/L (algae, 72-h EC50). Long-term ecotoxicity data are not available and the substance was concluded to be not readily biodegradable. As such, based on available data 1,3-Propanediol, 2,2-bis(hydroxymethyl)-, allyl ether is concluded to be 'not classified' for aquatic hazard classification under CLP (EC No. 1272/2008), but is classified as Aquatic Acute category 3 (H402) (Harmful to aquatic life) under GHS. Given the absence of long-term ecotoxicity data and the fact that the substance is not readily biodegradable, aquatic chronic classification has been derived based on available acute ecotoxicity data as Aquatic Chronic category 3 (H412) (Harmful to aquatic life with long lasting effects) under CLP (EC No. 1272/2008) and GHS.
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.
