Applicant's summary and conclusion
- Conclusions:
- The surface tension of a 1 g/l solution has been determined to be 32.3 mN/m at 18.5 ± 0.5 degC and can be considered to be a surface active material based on Method A5 of Commission Directive 92/69/EEC.
- Executive summary:
In a general physico-chemical properties study (525/026), the surface tension of a 1 g/l solution has been determined to be 32.3 mN/m at 18.5 ± 0.5 degC and can be considered to be a surface active material based on Method A5 of Commission Directive 92/69/EEC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
