- Reaction mass of 2-[7-isopropyl-5-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane and 2-[8-isopropyl-6-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane
- EC Number:
- 916-737-4
- Molecular formula:
- Reaction mass of 2-[7-isopropyl-5-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane and 2-[8-isopropyl-6-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane
- IUPAC Name:
- Reaction mass of 2-[7-isopropyl-5-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane and 2-[8-isopropyl-6-methylbicyclo[2.2.2]oct-5-en-2-yl]-1,3-dioxolane

Applicant's summary and conclusion
- Conclusions:
- The surface tension of a 90% saturated aqueous solution of the substance has been determined as 65.8 mN/m at 20°C using the OECD Harmonized ring method (GLP-compliant study in accordance with EC A.5 and OECD 115). Because this is not < 60 mN/m, the substance is not surface active according to the EC A.5 guideline.
