Detergents, familiar and indispensable products in the home, are synthetic surface active agents that are chemically classified as anionic, nonionic, or cationic (Table II–23). Most of these products also contain bleaching (chlorine-releasing), bacteriostatic (having a low concentration of a quaternary ammonium compound), or enzymatic agents. Accidental ingestion of detergents by children is very common, but severe toxicity rarely occurs. However, the introduction of concentrated, single-use laundry detergent packets ("pacs" or "pods") in 2012 has resulted in an increase in reported serious ingestions, including some deaths. Overall, laundry detergent packet exposures are more severe than exposures to laundry nonpacket products. In addition, laundry packet exposures are more severe than both dishwasher packet and nonpacket exposures.
