CAS number: 95009-65-7
The partition coefficients for members of the category Rosin adducts and rosin adduct salts range from 0.4 to 5.89 The partition coefficient of Rosin, maleated is 2.2 – 5.89 in unbuffered media and 1.5 - >6 at pH 2The partition coefficient of Rosin, fumarated is 2.8 at pH 3.93 – 4.47. A supporting study determined a log Kow of 2.7 – 3.6 at pH 7.5 and 4.4 – 7 at pH 2, both measured at 35°C The partition coefficient of Rosin, fumarated, reaction products with formaldehyde is 3.3 at pH 3.99 – 4.37The partition coefficient of Fatty acids, tall oil, oligomeric reaction products with maleic anhydride and rosin, calcium magnesium zinc salts is 0.4 at pH 5.43
GLP-compliant, guideline studies (Chilworth Technology 2010) are
available for Rosin, fumerated, Rosin, fumarated, 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 2000) is available for Rosin,
maleated. An additional GLP-compliant, guideline study (Water Quality
Institute 1992) is available for Rosin, fumarated. The range of results
from all reliable, guideline studies is provided.
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.
wide range of partition coefficient values for substances in this
category is due to the chemical structures of the substances, as they
are composed of ionisable organic acids.The
substances in this category are UVCB mixtures and therefore can exhibit
more than one peak and log Kow value.
