Substance characterisation

The test substance Vetivert Oil is a Natural Complex Substance (NCS) which is a subgroup of Complex reaction products or Biological material (UVCB substances).

In a key study, vetivert oil was found to be not readily biodegradable.

Vetivert oil is a NCS consisting of > 140 constituents. For 24 of the major constituents, divided over 3 different functional groups (alcohols, hydrocarbons and ketones), Log Kow values have been estimated. These 24 constituents make up 70.6% of the total composition of vetivert oil. Based on these estimations it can be concluded that > 25% w/w of vetivert oil has a Log Kow > 4 (as alcohols are the main component).

Classification

Vetivert Oil is not readily biodegradable and the Log Kow is > 4 for > 25 % of the constituents. As there is no tested BCF for vetivert oil for its main constituents at the moment, a classification for long-term effects in the environment is applied for both the classification according to Directive 67/548/EEC (DSD) and according to Regulation 1272/2008/EC (CLP).
