Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Koc and log Koc values of the test substance at neutral pH were >4.3E5 and >5.63 respectively.

Key value for chemical safety assessment

Koc at 20 °C:
430 000

Additional information

Alkylated naphthalene, EC Number 700-826-8, is a close structural analog of the Alkylnaphthalene being assessed in this dossier. The substances have similar chemical and physical properites and therefore the Adsorption Coefficient (Koc) testing for Alkylated naphthalene, EC Number 700-826-8, can be used as read-across to the alkylnaphthalene in this dossier.

The HPLC method (OECD 121) using soil-adsorption-reference data was applied for the determination of the adsorption coefficient (Koc) of alkylated naphthalene. The Koc and log Koc values of the test substance at neutral pH were >4.3 × 105and >5.63 respectively.

[LogKoc: 5.63]
