The Rosin adducts and rosin adduct salts category is a UVCB
category and includes rosin or rosin salts that have been chemically
reacted with either fumaric acid or maleic anhydride.Rosin
acids are the predominant components of rosin (>85%). Rosin acids are
composed of three skeletal classes oftricyclic carboxylic
acids which share similar structure, but vary in the position of the
double bonds and methyl groups. As each member of this category is a
UVCB, the organic components will vary in type and proportion.However,
once in water, the maleic anhydride form will hydrolyse to result in the
same structures as rosin reacted with fumaric acid.The presence of a
metal cation will not alter the structure of the organic component of
the molecule. The organic component can therefore be viewed as
equivalent across the category, and biodegradation results from one
category member can be read across to other substances within the
Reliable studies are available for several category members and on
the basis of the study results the substances would not be considered to
be readily biodegradable.
