Key value for chemical safety assessment
Additional information
Discussion for CAS # 756-13-8:
Surface tension measurement for CAS# 756-13-8 need not be conducted per Annex VII, column two if based on structure, surface activity is not expected or predicted. As the test substance does not contain both hydrophilic and hydrophobic domains, and further has a hydrolytic half-life in water of <2.5 minutes, no surface activity is expected. Nevertheless, surface tension of CAS# 756-13-8 was assessed in three studies. In the key study, CAS# 756-13-8 as a pure liquid had a measured surface tension of 10.80 mN/m at 25°C. In the supporting study, the measured surface tension was 11.76 mN/m, temperature not specified. Both studies used the platinum plate method for determination of surface tension. In the remaining study, surface tension of a water solution of CAS# 756-13-8 was stirred overnight before measurement. Owing to rapid hydrolytic half life, the test functionally measures surface tension of perfluorpropionic acid (PFPA, CAS# 422-64-0) and is not considered further. The key study was performed using standard instrumentation. The platinum plate method used is permitted under OECD TG115, but study compliance with test guidelines and GLP standards cannot be assessed. The supporting study reports only the instrument used and the result (no temperature specified), and cannot be assessed as to its reliability. The remaining study is functionally a test of surface tension of a PFPA solution, and is not relevant to surface tension of pure CAS# 756-13-8. Therefore, the results of the key study are accepted as the density of CAS# 756-13-8.
