Quaternary ammonium compounds are commonly used on which type of material?

• A. Wood
• B. Fabrics
• C. Surfaces
• D. Metals

Answer: (C)

Quaternary ammonium compounds are cationic disinfectants that work best when they can form a stable, antimicrobial film on a surface. They are designed for hard, nonporous materials where this film stays put long enough to kill microbes during contact time. That makes them ideal for surfaces like countertops, floors, and equipment in pest control and sanitation settings. Porous materials such as fabrics or wood tend to absorb or wick away the active chemical, which reduces effectiveness and can cause issues with residue or damage, so quats aren’t the go-to choice for those materials. While metals can be treated in some cases, the common and most reliable use described is on surfaces.
