Specific details on test material used for the study:

- Names of test material (as cited in study report): Lemonile; 3,7-dimethyl-2,6-nonadienenitrile
- Substance type: Colourless liquid
- Physical state: Liquid
- Analytical purity: 99.4 % (sum of components)
- Lot No: VE00101509
- Expiration date of the lot/batch: 2012-09-09

Temp.:

20 °C

Vapour pressure:

1.7 Pa

Headspace vapour concentrations of Lemonile as found after an equilibration time of 24 h, 48 h and 72 h are exposed in Table 1. The values are in agreement, indicating that the headspace was saturated in test substance vapour.
