Quaternary Ammonium Compounds QUATS

SCA endorses products with the Toxic-Free Tick, that do not contain QUATs. Generally there is a lack of safety data concerning QUATS & most of the QUATS have environmental concerns for toxicity. Some can cause skin irritation & allergic contact dermatitis, some can interfere with our hormones. QUATS are toxic to aquatic organisms.

  • "This ingredient and related ingredients are all called quats—”quaterny ammonium compounds” that are used in a wide range of products as preservatives, surfactants, and germicides. Some are also used as conditioning agents, giving skin and hair a slippery and smooth feel." - AnneMarieSkincare

  • Disinfectant products; "effective against most vegetative bacteria and enveloped viruses, and some fungi." - Science Direct

  • "In addition to harming germs, quats are lung irritants and can contribute to asthma and other breathing problems. They irritate skin too – and can lead to rashes. (This is one reason why packages of antibacterial wipes strongly recommend washing your hands after use. A factor that really takes the convenience out of using a wipe in the first place!)" - www.womensvoices.org
