Applicant's summary and conclusion
- Conclusions:
- The substance is not readily biodegradable. It will degrade in the presence of light in the water, but not in the dark.
- Executive summary:
The substance does not contain hydrolysable groups. It is estimated that the substance has a low potential to hydrolyse in the dark (note the hydrolysis testing was performed according to Directive 84/449/EEC, C.10 and based on the test conditions, photolytic interference should be avoided by appropriate means). The substance is stable in acidic and neutral pH conditions. There is no information about whether it undergoes hydrolysis at alkaline conditions. Based on the test result, hydrolysis in the absence of light is not expected.
However, its eco-toxicological information showed that the substance has a poor stability. As the substance is a photoinitiator, it would be expected to rapidly degrade in the environment upon exposure to nature light.
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).
