The log partition coefficient of rosin, reaction products with formaldehyde is 5.36 at pH 6.03



Key value for chemical safety assessment

Additional information

A GLP-compliant study, conducted according to EU Method A.8 (flask method), was provided for Rosin, reaction products with formaldehyde ( Chilworth Technology, 2010b). An additional supporting study, conducted according to OECD Guideline 117 (HPLC Method) was also provided for Rosin, oligomers (SafpPharm Laboratories Limited, 1992a)
