In an acute dermal toxicity study (Hazleton, 1991), groups of 5 -7 weeks old Sprague-Dawley rats (male / female) were dermally exposed to Vanilline for 24 hours to approximately 10% area of the body at doses of 2000 mg/kg bw. Animals then were observed for 14 days.
In the preliminary study, 2 males and 2 females per group were treated under the same conditions as those employed in the main study, at the dose levels of 1000 and 2000 mg/kg. No deaths were seen at all dose level tested of 2000 mg/kg.
Dermal LD50 Combined > 2000mg/kg bw. No clinical sign, except yellowish coloration of the skin and no mortality occurred at this dose.
According to classification criteria of EC regulation 1272/2008 Vanillin should not be classified for acute dermal toxicity based on the LD50 in male and female rats.
