Quaterinary Ammonium Chlorides
Definition
Quaternary ammonium salts are cleaning agents, or "surfactants," that can also be found in disinfectants, fabric softeners, and shampoos. There is concern that quaternary ammonium salts can cause dermal and respiratory allergies in sensitized populations. However, concentrations of quaternary ammonium salts used in SC Johnson products are below levels that have shown effects in sensitization tests.
