Environment-friendly antifoulants for the prevention of biofouling
Environmentally-friendly alternatives to organometallic antifoulants that are efficacious at preventing biofouling by organisms such as the zebra mussel. Preferred antifoulant compositions utilize compounds having a Lipophilic-Amide-Spacer-ElectroNegative (“LASEN”) structural motif, such as capsaicin, and compounds having a TetraHydroCannibinoid (“THC”) structural motif. The antifoulant compositions are non-toxic, and effective.
