Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- log Koc > 5.6 [91.4 % of the test material C4-C10 branched and linear hydrocarbons (light) – Naphtha]
- Distribution in water (up to 69.1 %) and air (up to 48.8 %) [respective hydrocarbons (C4, C7, C10, branched and linear)]
Additional information
Adsorption/desorption:
The adsorption coefficient (Koc) of the test material has been determined to be greater than 111 to >4.27 x 10e5, log10 Koc 2.05 to >5.63, using the HPLC screening method. By fraction collection and subsequent GC analysis, 91.4% of the test material had a log10 Koc value greater than 5.6.
Distribution modelling:
The distribution of respective hydrocarbons (branched and linear, C4 -C10) in the environmental compartments, air, water, soil, and sediment, has been calculated using the level III fugacity model, included in EPI Suite model. Distribution ranges of linear hydrocarbons (C4, C7 and C10) is between 29.6 - 48.8 % to air, 50.6 - 69.1 % to water, while partitioning into soil or sediment does not exceed 1.73 % or 2.27 %, respectively. An overall range of the distribution of the respective, branched hydrocarbons (C4, C7 and C10) is between 1.8 - 38.5 % to air, 60.1 - 66.1 % to water, while partitioning into soil or sediment does not exceed 1.27 % or 0.867 %, respectively.
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.
