A European bug-fighting secret has hit the U.S. It's a chemical called IR-3535, and it's been used in Europe and other parts of the world for more than 20 years. The concoction repels mosquitos, deer ticks, body lice, and biting flies. The active ingredient is ethyl butyl-acetyl-amino-propionate. That's why it's easier to just call it IR-3535.
Here's the best part. IR-3535 has passed the EPA toxicity tests indicating that it's safe for children, even if they swallow it. The jury is still out on how it stacks up against Deet, the gold standard bug fighter in this country. But this is the first time in 50 years a new synthetic insect repellent has hit the market in the U.S. So far, the new ingredient is only available in a bug lotion sold by Avon.
