Mitin FF

Description

[Ciba-Geigy, originally Geigy] A complex chlorinated phenyl urea compound synthesized in 1938. Mitin FF is sold as a wool mothproofing agent and insecticide that protects keratin-based fibers like wool from clothes moths and carpet beetles. It bonds chemically to fibers much like an acid dye, preventing it from easily washing or rubbing off during routine cleaning. Mitin FF was registered in the US in 1948, and has been used extensively since then on blankets, rugs and industrial yarns.
