Quats, short for quaternary ammonium compounds, are a group of chemicals commonly used as disinfectants and antiseptics. They are effective against a wide range of bacteria, viruses, and fungi, making them popular in cleaning products, sanitizers, and personal care items. Quats work by disrupting the cell membranes of microorganisms, leading to their destruction. These compounds are often found in household cleaners, surface disinfectants, and even some hair conditioners. While quats are generally safe for use, they can cause skin irritation in some individuals and may contribute to antibiotic resistance if used excessively. Proper usage and following safety guidelines are essential.
