Results and discussion
Any other information on results incl. tables
Since this material is not volatile, the only potential photolytic reaction that needs to be considered is direct photolysis at the earth's surface. Direct photolysis is not possible because this material does not have a chromophore absorbing at a wavelength of 290 nm or above, and the presence of such a chromophore is a necessary condition for photolysis.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- Direct photolysis of sodium formate is not possible, since the substance does not have a chromophore absorbing at a wavelength of 290 nm or above, which is a prerequisite for photolysis.
- Executive summary:
Since this material is not volatile, the only potential photolytic reaction that needs to be considered is direct photolysis at the earth's surface. An expert judgement is available based on reliable handbook data for sodium formate, which describes that direct photolysis is not possible because this material does not have a chromophore absorbing at a wavelength of 290 nm or above, and the presence of such a chromophore is a necessary condition for photolysis (Lymanet al., 1990). Phototransformation testing would there be redundant for sodium formate.
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.
