Data sets of surface tension of puncine derivatives (octyl-, nonyl-, decyl-, undecyl- and heptadecyl-punicine) and oleic acid/sodium oleate in water measured with bubble pressure tensiometry at different pH and different concentrations.

Measurements were done at BP100 of KRÜSS GmbH. For each mesurement the adequate amount of a 25mM surfactant solution (40 vol-% EtOH and 60vol-% distilled water) werde diluted in 70 mL of distilled water.

data files are named as follow: date of measurement_type of surfactant_ concentration of surfactant_ pH of measurement_number of measurement

surfactants: OA Oleic acid NaOL Sodium oleate OP Octyl punicine NP Nonyl punicine DP Decyl punicine UDP Undecyl punicine HDP Heptadecyl punicine
