Results and discussion

Surface tension
Surface tension:
63.6 mN/m
Temp.:
21 °C
Conc.:
90 vol%
Remarks on result:
other: from duplicate aqueous samples prepared at 90% saturation, individual replicate values being 63.6 and 63.6 mN/m

Any other information on results incl. tables

Based on analytical data generated during the determination of water solubility, the dissolved content of the sample solutions was expected to be predominantly hydrolysis/degradation products, as opposed to the initial parent test item. This was concluded not to impact on the validity of the test as, due to the rapid hydrolysis/degradation observed for this test item, the hydrolysis/degradation products were considered more relevant with respect to environmental risk assessment, with the parent test item expected to degrade on accidental release into water.

Applicant's summary and conclusion

Conclusions:
The surface tension of Linalyl propionate was 63.6 mN/m at 21.0 ± 0.5 °C (from duplicate aqueous samples prepared at 90% saturation, individual replicate values being 63.6 and 63.6 mN/m). The test item was considered not to be surface-active.
Executive summary:

The surface tension of Linalyl propionate was measured according to OECD Guideline No. 115 (ring method).

The surface tension of Linalyl propionate was 63.6 mN/m at 21.0 ± 0.5 °C (from duplicate aqueous samples prepared at 90% saturation, individual replicate values being 63.6 and 63.6 mN/m). The test item was considered not to be surface-active.
