Description of key information
Based on a weight of evidence approach, the acute toxicity of lavandin oil heavy fraction to aquatic invertebrates (daphnia) can be estimated using adequate toxicity data of major constituents, greater than 1% in the mixture. Six constituents were considered representing more than 85% of the UVCB substance.These data are summarized in the table below:
| Constituent names | CAS nr | LC50 daphnia 48h (mg/L) | source |
| acetate linalyle (67%) | 115 -95 -7 | 0.82 | ECOSAR V1.11 |
| borneol (5%) | 507 -70 -0 | 13.38 | ECOSAR V1.11 |
| acetate lavandulyle (5%) | 25905-14-0 | 0.681 | ECOSAR V1.11 |
| linalol (3%) | 78-70-6 | 4.698 | ECOSAR V1.11 |
| caryophyllene (3%) | 87-44-5 | 0.019 | ECOSAR V1.11 |
| lavandulol (2%) | 58461-27-1 | 3.903 | ECOSAR V1.11 |
using additivity formula mentionned in CLP regulation 1272/2008 in section 4.1.3.5.2., the LC50 daphnia for the lavandin oil heavy fraction is estimated at 2.92 ml/L.
