Description of key information
Substance characterisation
The test substance Tangerine oil is a Natural Complex Substance (NCS) which is a subgroup of Complex reaction products or Biological material (UVCB substances). With 97% of the constituent composition of Tangerine oil known, this NCS can be considered as a well defined NCS. The constituents of Tangerine oil are predominantly alicyclic or acyclic unsaturated monoterpene hydrocarbons. In the typical Tangerine oil, the main constituent d-limonene is present at 88% of the composition.
The composition with mainly monoterpene constituents represents a relatively homogenous type of NCS. In spite of the structural similarities of many constituents, the ranges for water solubility, volatility, adsorption and lipophility are considerable and thus the environmental behaviour of the constituents may vary. Due to these differences the assessment of the environmental properties of Tangerine oil is based on data for the constituents.
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), Tangerine oil is to be considered as a readily biodegradable substance. The water solubility ranges from 2.6 to 1101 mg/l for the constituents. The water solubility is > 10 mg/l for 95% of the constituent composition including the main constituent d-limonene.
The log Kow of the constituents ranges from 3.38 – 4.9. Log Kow is above 4 for 92% of the composition of this NCS. With log Kow 4.38, d-limonene represents the group with a relatively high log Kow (Koc of d-limonene estimated at 2413). Most constituents may have a tendency to sorb to organic matter.
The estimated vapour pressure of Tangerine oil is 198 Pa, ranging from 11 to 536 Pa for the constituents. For d-limonene (typically 88%) the vapour pressure is 193 Pa and another 3% of the constituents composition has a higher vapour pressure. This indicates that partitioning by volatilisation will be significant.
Classification
Although Tangerine oil is considered readily biodegradable, log Kow is >4 for typically 92% of the constituent composition. As there is no tested BCF for Tangerine oil or for its main constituent d-limonene at the moment, a classification for long-term effects in the environment is applied as a worst case for both the classification according to Directive 67/548/EEC (DSD) and according to Regulation 1272/2008/EC (CLP).

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.
