Interesting links. Sorry for the hi-jack but...
That second link lead me to SODIUM BENZOATE, BENZOIC ACID which got me thinking about Benzyl alcohol (BA) because it is used so often in the injectable formulas, especially steroids that bodybuilders use. So those links led me to the following:
Carcinogenicity of benzyl acetate, benzyl alcohol, and benzaldehyde
With benzyl alcohol, no treatment-related increase in tumours was observed in F344/N rats or B6C3F1 mice after administration of <400 mg/kg body weight per day in rats or <200 mg/kg body weight per day in mice by gavage in corn oil (US NTP, 1989).
So THAT is good news.
Reproductive toxicity doesn't appear too bad as well:
Reproductive toxicity of benzyl acetate, benzyl alcohol, and benzaldehyde
Benzyl alcohol at 550 mg/kg body weight per day by gavage on days 6-15 of pregnancy had no effect on gestation index, average number of live pups per litter, postnatal survival, or pup body weight on days 0 and 3 in CD-1 mice (York et al., 1986), while 750 mg/kg body weight per day (days 7-14) induced a reduction in the pup weight and maternal weight gain, but no pup mortality or changes in mating or gestation indices, the total number of resorptions, or the number of live pups per litter (Hardin et al., 1987).
