After oral uptake, Na-benzoate is rapidly absorbed from the gastro-intestinal tract and combines with glycine in the liver forming hippuric acid (Feldman et al., 1970; US FDA 1972; WHO 1996; Feillet et al., 1998) which is rapidly excreted via the urine (about 75%) within 6hr and rest within 2-3 days (Kubota et al., 1988; Fujii et al., 1991; Kubota et al., 1991).
