Applicant's summary and conclusion
- Conclusions:
- The substance is not surface active.
- Executive summary:
In an OECD harmonised ring test the surface tension of the substance was determined in 5-fold using a tensiometer. The corrected surface tension is 64.7 mN/m. The substance is considered not surface active
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
