Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

A calculated Koc value of 235 L/kg indicates that the substance will have a low potential to adsorb to sediment/soil.

To assess the volatilisation potential of the substance a Henry's law constant was calculated which showed a value of 0.186 Pa.m3/mol (at 12 °C). Based on this value alpha-Terpineol will remain in the water phase and does not have a tendency to partition to air.

Based on Level III environmental distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 98 -55 -5 and the measured physico-chemical parameters as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (73.9%) and water (25.9%) with small amounts to sediment (0.15%) and air (0.03%).

The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plant. Model calculations show that 85.4% of the substance will be degraded and that 12.4 %, 2.16 % and 0.073 % will partition to water, sewage sludge and air, respectively.
