Description of key information

The water solubility of substances in the category Rosin adducts and rosin adduct salts range from 1.38 mg/L to 60 mg/L  
Water solubility of Rosin, maleated is 1.38 mg/L
Water solubility of Rosin, fumarated is ca. 9 mg/L
Water solubility of Rosin, fumarated, reaction products with formaldehyde is 60 mg/L
Water solubility of Fatty acids, tall oil, oligomeric reaction products with maleic anhydride and rosin, calcium magnesium zinc salts is <10 mg/L

Key value for chemical safety assessment

Additional information

GLP-compliant, guideline studies (Chilworth Technology 2010) are available for Rosin, fumarated, Rosin, fumerated, reaction products with formaldehyde and Fatty acids, tall oil, oligomeric reaction products with maleic anhydride and rosin, calcium magnesium zinc salts. A GLP-compliant, guideline study (Inveresk 2004) is available for Rosin, maleated. An additional GLP-compliant, guildeline study (Inveresk 2004) is available for Rosin, fumarated.

Although the Chilworth (2010) studies follow standard guidelines, there are concerns that the test method may not be appropriate for the test substance as there is a large difference in results between the preliminary study and the study following the column elution method. For this reason, where both Chilworth and Inveresk studies are available a substance the Inveresk values are considered as key.

In addition, calculated values are provided for each of the substances (Marlin Consultancy 2010). Where test data are available this should be used instead of calculated data, therefore the tested values are considered as key for this category.
