Serious eye damage/eye irritation - Category 2

Studies in rabbits have shown that hydroxycitronellal is converted to two primary metabolites: reduction to the alcohol 7-hydroxycitronellol and oxidation to the carboxylic acid 7-hydroxycitronellylic acid. On average, about 50% of hydroxycitronellal is excreted as 7-hydroxycitronellylic acid which is therefore regarded as the major metabolite.
