Applicant's summary and conclusion
- Conclusions:
- Reference 1) Degradation in percentages (for indirect photolysis) was estimated ca.50 after 3 days with APOWIN (Episuite).
Reference 2) Can decompose on photolysis.
Reference 3) May directly photolyze. - Executive summary:
Three data are available concerning the potential phototransformation of Dibenzoyl peroxide. Nevertheless, no information are available in order to challenge the relevance of these data.
Reference 1) Degradation in percentages (for indirect photolysis) was estimated ca.50 after 3 days with APOWIN (Episuite).
Reference 2) Can decompose on photolysis.
Reference 3) May directly photolyze.
Based upon these data, Dibenzoyl peroxyde may decompose due to photolysis.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
