Log Kow: -0.2 to -1.8 (Citric acid)
Trizinc dicitrate may dissociate to citrate and zinc in water. For the
purposes of exposure estimation and risk characterisation, zinc and
citrate are considered separately.
Log Kow is not relevant for the zinc ions.
A number of studies are available that indicate that citric acid/citrate
has a low Log Kow. Secondary sources to which data could not be assigned
gave values of -1.64 and -1.76. A reliable study conducted according to
generally accepted scientific principles gave values in the range -1.6
to -1.8 (Kuban 1991). A reliable study conducted according to generally
accepted scientific principles, ion-pair octanol water partition
coefficients of -0.76±0.10 for H2A- and -0.21±0.11 for H3A were
determined (Avdeef 1992). There is some variation in the results but
this is not considered critical for a substance with very low Log Kow.
