Safety

Low concern · Safe at standard use

(E)-Geranyl propionate is the propionate ester of geraniol, occurring at low levels in a few herbaceous essential oils.

Skin. A 4 percent patch test on volunteers produced neither irritation nor sensitization. Applied undiluted to rabbit skin for 24 hours, it was non-irritating.

Oral and dermal. Acute oral LD50 in rats and acute dermal LD50 in rabbits both exceed 5 g/kg.
