Executive summary:

In an acute dermal toxicity study, 10 guinea-pigs were administered a single dermal dose of myrtle essence at 5000 mg/kg bw. Animals were then observed for mortality and clinical signs of toxicity for 14 days.

Dermal reactions noted were slight redness (3/10), moderate redness (7/10), slight edema (4/10) and moderate oedema (6/10) at the site of application.

One animal was found dead on Day 6.
