Results and discussion

Surface tension
Surface tension:
70.2 mN/m
Temp.:
20 °C
Conc.:
90 vol%
Remarks on result:
other: from duplicate aqueous samples prepared at 90% saturation, individual replicate values being 69.7 and 70.7 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 also contain a significant concentration of hydrolysis/degradation products, as well as 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 equally 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 isobutyrate was measured according to OECD Guideline No. 115 (ring method).
The surface tension of Linalyl isobutyrate was 70.2 mN/m at 20.0 ± 0.5 °C (from duplicate aqueous samples prepared at 90% saturation, individual replicate values being 69.7 and 70.7 mN/m). The test item was considered not to be surface-active.
Executive summary:

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

The surface tension of Linalyl isobutyrate was 70.2 mN/m at 20.0 ± 0.5 °C (from duplicate aqueous samples prepared at 90% saturation, individual replicate values being 69.7 and 70.7 mN/m). The test item was considered not to be surface-active.
