Avon Skin So Soft Spray, used with great success
Avon finally reacted to the repeated studies that Skin So Soft did nothing to repel insects -- they added picaridin, which IS effective against mosquitoes!
Picaridin repels insects, ticks and chiggers. It is a synthetic compound first made in the 1980s. It was made to resemble the natural compound piperine, which is found in the group of plants that are used to produce black pepper. Picaridin has been widely used as an insect repellent in Europe and Australia, but has only been available in the United States since 2005.
Picaridin can be used on human skin or clothing to repel mosquitoes, biting flies, ticks, fleas, and chiggers. These products may be pump sprays, liquids, aerosols, or wipes. There are about two dozen products with picaridin in them for sale in the United States.
Always follow label instructions and take steps to avoid exposure. If any exposures occur, be sure to follow the First Aid instructions on the product label carefully. For additional treatment advice, contact the Poison Control Center at 1-800-222-1222. If you wish to discuss a pesticide problem, please call 1-800-858-7378.
Some people have had skin irritation from using products containing picaridin, although this is very uncommon. If picaridin gets into someone's eyes, it may also cause irritation. When researchers fed large doses of picaridin to rats, the rats lost weight and their kidneys were affected. Picaridin is considered practically nontoxic if inhaled.
When researchers applied picaridin to the skin of rats, 60% of it went through the skin. In humans, less than 6% of the picaridin applied to skin was absorbed. Picaridin may be broken down once it is in the body. Rats and humans excrete almost all of it in their urine within a day of exposure.
Researchers did not see increases in cancer among laboratory animals after putting picaridin on the animals' skin for two years. The U.S. EPA decided that picaridin is not likely to cause cancer based on long-term skin exposure studies in rats and mice.
DEET is probably the insect repellent that melted plastic in the above post, and users should read about it (I use it to repel bedbugs, but shower in the morning).
