Details on test material:
Name: Linalool Oxide
Batch No.: PE00097239
Purity: 98.5 % (Sum of cis- and trans- isomers)
Expiry date: 2016-08-27


Please note that although the substance is described in the report with the IUPAC name: 2-(5-methyl-5-vinyltetrahydrofuran-2-yl)propan-2-ol related to the CAS number 1365-19-1, recent analytical data had been determined the substance to be a multi-constituent 2-(tetrahydro-5-methyl-5-vinyl-2-furyl)propan-2-ol related to the CAS number 60047-17-8.

As the chemical manufacturing process has not changed since the report was written, the recent analytical information is relevant to the batch which was tested.

Any other information on results incl. tables

The surface tension of a 1 g/L aqueous solution of Linalool Oxide (batch number: PE00097239) was determined according to OECD Guideline 115 and Council Regulation (EC) No. 440/2008 Method A.5 from 2015-02-19 to 2015-02-20 at Dr.U.Noack-Laboratorien, 31157 Sarstedt, Germany. The determination was carried out with a tensiometer in ten successive measurements with a standard deviation £ 0.05 mN/m at a temperature of 20 ± 0.5 °C.

The surface tension of a 1 g/L aqueous solution of the test item Linalool Oxide at 20 °C was determined to be 52.02 mN/m (standard deviation ± 0.04 mN/m). Due to the fact that the surface tension is

Applicant's summary and conclusion

Conclusions:
The surface tension of a 1 g/L aqueous solution of the test item Linalool Oxide at 20 °C was determined to be 52.02 mN/m (standard deviation ± 0.04 mN/m). Due to the fact that the surface tension is < 60 mN/m, the test item is classified as surface-active substance.
