Description of key information
Substance characterisation
The test substance Spearmint oil is a Natural Complex Substance (NCS) for which typically 92.80% of the constituents are identified. The constituents of Spearmint oil are mainly monoterpenoid aldehydes, cyclic monoterpenes and alcohols.
Based on the constituent approach as described in the industry protocol for the REACH registration of NCSs of botanical origin used as fragrance ingredients (see footnote 1), the water solubility of the different constituents ranges from 0.02 to 1767 mg/l. The vapour pressure of Spearmint oil as a whole is estimated 60.36 Pa, and ranges from 3.04 to 536 Pa for its different constituents. The Log Kow of the constituents ranges from 2.73 to 6.99. In addition it can be observed that the Log Kow is above 4.5 for 17.86 % of the typical substance composition, whereas at above 4 for 19.3% of the typical composition. The log Koc of the different constituents ranges from 1.53 to 4.30. Based on the readily biodegradability of 89.18% of its typical concentration, Spearmint oil is considered as a readily biodegradable.
Environmental fate and pathways
As can be seen from the above, properties as water solubility, volatility, adsorption and lipophilicity, can only presented as ranges among the constituents and a unique value each of these physico-chemical property cannot be attributed to the NCS as a whole. Environmental behaviour of Spearmint oil will thus preferably be based on data for the individual constituents. When using the LCID methodology + (this means with modification to better take into account all constituents, including whose without harmonised classification) (CEFIC/VCI, 2016), Carvone is identified as lead constituent. With a 68% typical concentration this constituent may drive an important part of the environmental behaviour of Spearmint oil. Moreover, by comparing environmental assessment conducted with Limonene or a mixture of Limonene/Carvone, it confirmed that the use of Carvone in the environmental exposure assessment is a worst-case to describe the environmental risks of spearmint oil.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
