Antibacterial and disinfecting ingredients in detergents are added to help kill or inhibit the growth of bacteria and other microbes on surfaces and fabrics, providing enhanced hygiene beyond basic cleaning.
Common Antibacterial Ingredients in Detergents: Triclosan and Triclocarban ( widely used in soaps and detergents but concerns about their safety, environmental impact, and contribution to antibiotic resistance led to regulatory bans on their use in consumer antibacterial soaps by the FDA in 2016), Benzalkonium Chloride ( widely used in disinfectants and some detergent formulations ), Chloroxylenol (PCMX) (antimicrobial chemical permitted in some antiseptic wash products and disinfectants, functioning by disrupting cell walls of bacteria), Alcohols (Ethanol, Isopropanol)( Common active ingredients in hand sanitizers and some disinfectant wipes), Sodium Hypochlorite (A strong disinfectant widely used in household and industrial cleaning products, including disinfecting laundry detergents), Hydrogen Peroxide(used as a disinfecting agent and often formulated with other ingredients to increase its effectiveness)
These agents can be combined with surfactants and builders in detergents to provide both cleaning and antimicrobial efficacy.
The FDA banned 19 antibacterial active ingredients, including triclosan and triclocarban, because of concerns include the potential for antimicrobial resistance, skin irritation, environmental persistence, and toxicity to aquatic organisms.
