- Conclusions:
- The surface tension of this substance was deduced from the measurement of a similar substance.
The source substance 2,3-dihydroxypropyl laurate (CAS 142-18-7) is a mono-constituent, C12, monoester. The surface tension was determined to be ca. 34.3 mN/m at 20 °C (80% saturated solution, 5 mg/L) at 20 °C.
The target substance is a UVCB, C12, mono, di and triester. It can be deduced that the target substance is surface active.
