bentoquatam

Bentoquatam is a topical skin protectant used to prevent allergic contact dermatitis caused by exposure to urushiol, the allergenic resin found in poison ivy, poison oak, and poison sumac. It works by forming a physical barrier or coating on the skin that blocks plant oils from contacting and penetrating the skin, thereby reducing or preventing rash development. Bentoquatam does not treat existing rashes but is effective as a preventative measure when applied before exposure. The mechanism of action is primarily physical; it does not alter systemic immune responses. It is available over-the-counter as a lotion or suspension under brand names such as Ivy Block.
