IVYBLOCK HISTORY

In the early 1980s the U.S. Department of Agriculture in conjunction with the Dr. Gary Hoshide, head of the U.S. Forestry Service Health and Safety Division set out in search for a way to prevent poison ivy, poison oak and poison sumac rash. Occupational Safety and Health Administration (OSHA) had unearthed the top reason for lost-time injuries among forest firefighters-poison ivy rash. Hoshide hired scientists at the University of San Francisco to research the mechanism of the rash.

The search began with the medical team at University of San Francisco discovering that the rash did not spread under armpits of some firefighters where an antiperspirant was applied. Wanting to determine if there was a connection, they asked a chemical company lab in New Mexico to identify which ingredient might offer protection. They in turn sent it to a sister company in Louisville, KY-United Catalyst, Inc., now Süd Chemie.

Studying the chemistry, Süd Chemie's biochemists found the central compound that they were looking for was Quaternum-18 Bentonite (Q-18B). The next ten years were spent perfecting the chemistry, creating a product that would not only help firefighters in their daily work, but all who encounter the poisonous plants. Süd Chemie filed for patents, submitted a Drug Master File (DMF) and filed for a New Drug Application (NDA) with the FDA.

On August 26, 1996 the U.S. Food and Drug Administration (FDA) granted EnviroDerm Pharmaceuticals, Inc. the approval needed to market IvyBlock, the first and only poison ivy, poison oak and poison sumac skin protectant that can prevent the onset of this rash. IvyBlock has exclusive use of the active ingredient quaternium-18 bentonite, which now uses the CTFA name: Bentoquatam.
