Description of key information
Additional information
Photodegradation in water and hydrolysis have both been observed in preparatory work performed prior to undertaking an algae study (see 6.1.5) however half-lives in water cannot be accurately quantified from this data for use in risk assessment
Aldehydes in aqueous solutions are oxidised to form carboxylic acids, but this reaction is not sufficiently strong to consider the substance as a reducing agent. As the substance biodegrades readily further information on stability in water is not considered necessary.
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.
