Applicant's summary and conclusion
- Conclusions:
- R-Pantolactone has to be considered as a not surface active substance.
- Executive summary:
The surface tension of R-Pantolactone in water (at a concentration of about 0.1%) was determined to be 72.2 mN/m at 19.6 °C ± 0.1 °C. Based on the criteria as outlined in the EEC Guideline and the results of this study, R-Pantolactone has to be considered as a not surface active substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
