- Analytical purity: no data
- Batch No.: 4012745340
- Item No.:172734
Key result
Surface tension:
ca. 28 mN/m
50 °C
0 other: No values for concentration were provided.
Remarks on result:
other: The surface tension was found to be approx. 28 mN/m over a range of 44 – 58 °C.


The surface tension was found to be fairly constant over a range of 40 – 60 °C, with a value of approximately 28 mN/m.

The results indicate that the substance is surface active at these temperatures.

Description of key information

Surface tension: approximately 28 mN/m over a range of 40 – 60 °C (similar to OECD 115).

Key value for chemical safety assessment

Additional information

The surface tension of the substance Glycerides, C16-18 and C18-unsatd. mono- and di-, citrates (CAS 91052-16-3) was determined by the Wilhelmy plate method, equivalent or similar to OECD 115.
