Applicant's summary and conclusion
- Conclusions:
- The relative density ("D" _"4" ^"20" ) of the test susbtance was determined according to EC method A.3 and OECD 109. The relative density ("D" _"4" ^"20" ) of the test substance was determined to be 1.4874 relating to the density of water at 4 °C (0.999972 g/cm3).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
