Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The adsorption coefficient of Orivone has been determined to be 3.74E+02 (log10 Koc 2.57) using the HPLC screening method, designed to be compatible with Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001 Method C.19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008.

The Henry's Law constant is calculated using the equation from EUSES. Using a molecular weight of 168.28 g/mol, and the experimentally determined vapour pressure of 4.2 Pa (at 24 °C) and water solubility of 370.8 mg/L (at 24 °C) the Henry's Law constant at environmental temperature (12 °C) is calculated to be 0.964 Pa·m³/mol.

Based on Level III environmental distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 16587-71-6 and the measured physicochemical parameters (water solubility and log Kow) as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (80.5%) and water (17.8%) with minor amounts to air (1.55%) and sediment (0.24%).

The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plant (STP). Model calculations show that 0% of the substance will be degraded and that 93.9%, 4.44% and 1.66% will partition to water, sewage sludge and air, respectively.
