Description of key information

The adsorption coefficient was calculated using Quantitative Structure Activity Relationships (QSAR), the details of which are provided in the Technical Guidance Documents in support of Commission Directive 93/67/EEC on risk assessment for new notified substances.

The adsorption coefficient was calculated using the following equation:

Log10Koc = 0.81 10gl0 Pow + 0.10

Key value for chemical safety assessment

Koc at 20 °C:
3.43

Additional information

Using QSAR calculations the adsorption coefficient of S-900 has been determined as log10 Koc > 3.86.
