Several experiments were conducted to study the metabolism of esters of -hydroxybenzoic acid after oral (1000 mg/kg bw) or intravenous (50 mg/kg bw) administration to dogs. The esters were absorbed in the gastrointestinal tract and rapidly hydrolysed by esterases in the liver and kidney. In the case of butyl -hydroxybenzoate (No. 870), 48% was recovered after oral and 40% after intravenous administration. Liver preparations from dogs injected with 100 mg/kg bw of the methyl, ethyl, or propyl ester showed 100% hydrolysis within 3 min. In the case of the butyl ester, 100% hydrolysis occurred within 30–60 min (Jones et al., 1956).

The total annual production of the 46 flavouring agents in this group is 450 000 kg in Europe (International Organization of the Flavor Industry, 1995) and 1 800 000 kg in the USA (Lucas et al., 1999). Vanillin (No. 889), ethyl vanillin (No. 893), methyl salicylate (No. 899), and piperonal (No. 896), for which ADIs were previously established by the Committee, accounted for approximately 98% of the total annual volume in Europe and 99% in the USA. In Europe, the estimated daily intakes of these compounds were 55 mg of vanillin, 6.2 mg of ethyl vanillin, 0.5 mg of methyl salicylate, and 1.6 mg of piperonal. In the USA, the estimated daily intakes were 150 mg of vanillin, 43 mg of ethyl vanillin, 44 mg of methyl salicylate, and 3.2 mg of piperonal. The estimated daily intakes of two other flavouring agents in this group were in the low milligram range: the estimated intake of ethyl salicylate is 1.7 mg/person per day in the USA and that of -methoxybenzaldehyde is around 0.5 mg/person per day in both Europe and the USA. The estimated intakes of most of the other 40 flavouring agents were between 1 and 100 µg/person per day, and those of 10 were

Because of its prevalence and importance as a flavouring agent, vanillin (No. 889) has been the subject of numerous studies on metabolism. Male albino rats were given 100 mg/kg bw of vanillin in a solution of propylene glycol and water by stomach tube; urine and faeces were collected separately for 24-h periods, and bile samples were collected by cannulation of the common bile duct. Only trace amounts of benzoic acid derivatives remained in the urine after the first 24 h, and none remained after 48 h. Free and conjugated forms of vanillic acid and vanillyl alcohol accounted for 94% of the dose in the urine. Vanillin and its primary reduction and oxidation metabolites were also excreted in appreciable amounts in the bile. Bile collected for 5 h from two rats given vanillin at a dose of 100 or 300 mg/kg bw orally contained glucuronide conjugates of vanillin (6%), vanillyl alcohol (8%), and vanillic acid (9%) (Strand & Scheline, 1975).
In the investigation of the metabolism of various aromatic aldehydes and alcohols by rat intestinal microflora, the major metabolites were products of reduction. Microflora-mediated metabolic transformations included reduction, dehydroxylation, -demethylation, and decarboxylation, leading to a variety of derivatives of benzyl alcohol, benzoic acid, and toluene (Scheline, 1972). After incubation of vanillyl alcohol (No. 886) with rat caecal extract, vanillic acid and the toluene derivatives, 4-methylguaiacol and 4-methylcatechol from complete reduction of the alcohol functional group were present (Scheline, 1972). Analysis of urinary metabolites collected over the first 24 h from male rats given vanillyl alcohol by gavage at a dose of 100 or 300 mg/kg bw showed the presence of vanillic acid and traces of vanillyl alcohol and the glycine conjugate of vanillic acid. Smaller quantities of conjugated fractions of vanillin, guaiacol, catechol, 4-methylguaiacol, and 4-methylcatechol were also found. The presence of catechol and 4-methylcatechol indicated that decarboxy-lation and complete reduction of the alcohol function, respectively, occurred(Strand & Scheline, 1975).

Four groups of 11-week-old CD-1 mice (40 males and 40 females in the control group; 20 males and 20 females in the treated groups) were given methyl salicylate at a dose of 0, 100, 250, or 500 mg/kg bw per day by gavage in corn oil. All mice were treated for 1 week before, 14 weeks during, and 3 weeks after cohabitation, for a total treatment period of 18 weeks. Reproductive performance was assessed by observing the number of litters per breeding pair, the number of live pups per litter, the proportion of pups born alive, the sex ratio of pups born alive, and the live pup weight. Body weight was measured at weeks 1, 2, 3, 6, 10, 14, and 18. The only significant result was a slight decrease in the mean number of litters in mice at the highest dose. Two attempts to determine which sex was affected were unsuccessful owing to the poor fertility of the control groups in follow-up experiments. Eleven animals died during the 18 weeks of the study, the deaths being distributed relatively evenly among the treated groups. Gavage trauma was the commonest cause of death, and none of the deaths was considered related to the chemical or dose. The NOEL was 250 mg/kg bw per day (National Toxicology Program, 1984).

Body weight was measured weekly and haematological examinations were performed at the fifth month on animals at the two lower doses. After sacrifice, the organs were weighed, and gross and histological examinations were performed. All the animals at the highest dose were dead by the second week. Of the groups at 500 mg/kg bw per day, only two survived the duration of the experiment, while the rest died at weeks 2, 3, 5, and 8. The body weights of the groups at the two lower doses were not significantly different from those of controls, and haematological examinations showed normal values. Increased liver and kidney weights were seen at all doses but not in the animals placed on the recovery diet.
