Description of key information

The soil adsorption coefficient of Ca/Mg-salt of Fumarated Tall Oil Rosin was measured at pH 2 and pH 6 using the HPLC method according OECD TG 121. LogKoc values at pH 2 range between 3.02 and 4.50, where as at pH 6, logKoc values were found below 1.45 as well as between 2.04 and 3.09. The latter value was used for safety assessment.
