Based on the available data, substances in the category Rosin adducts and rosin adduct salts are not considered readily biodegradable.
Reliable studies are available for several
members of this category. The studies are all GLP-compliant and
conducted to standard guidelines.
Inveresk Research (2002) is a GLP-compliant
study that followed the standard OECD 301B test guideline. For rosin,
maleated, ca.0.34% degradation was demonstrated after 28 days and
ca.18.92% degradation after 28 days for Rosin, fumarated / maleated.
Neither of these substances would be considered readily biodegradable on
the basis of these results
Rosin, fumarated, reaction products with
formaldehyde is not being registered under REACH, but would fall within
the category definition. 26% degradation was demonstrated after 28 days
in an OECD 301B study (Harlan Laboratories, 2010). This would not be
considered readily biodegradable.
In an OECD 301D study with Rosin, fumarated
the test item achieved ca. 15% degradation after 28 days (Water Quality
Institute, 1993) and is not readily biodegradable.
Research (2002) is a GLP-compliant study that followed the standard OECD
302B test guideline. The biodegradation of the substance Resin and Rosin
Acids, Maleated, Potassium salts (CAS 85408-27-4) was determined to be
52.6% after 28d. The substance is not considered readily biodegradable.
studies are available for various substances that would fall within the
category definition, and the studies cover both
and maleated substances, it is considered to be appropriate to read
these results across to all category members. Based on the available
data, substances in the category Rosin adducts and rosin adduct salts
are not considered readily biodegradable.
