Biocide, preservative and surfactant associated with severe skin, eye, and respiratory irritation and allergies, benzalkonium chloride is a sensitizer especially dangerous for people with asthma or skin conditions such as eczema. Benzalkonium chloride is found in many household disinfectants and cleaning supplies. Regular use of products containing antimicrobials such as benzalkonium chloride could leads to the development of resistant bacteria in homes and food processing facilities.

Cosmetics and personal care products are not required to be tested for safety before being allowed on the market. The Skin Deep® scoring system was designed to help the public understand whether a product is safe to use or whether it contains ingredients of concern.
Every product and ingredient in Skin Deep gets a two-part score – one for hazard and one for data availability. The safest products score well by both measures, with a low hazard rating and a fair or better data availability rating.HOW WE DETERMINE SCORES
The Skin Deep ingredient hazard score, from 1 to 10, reflects known and suspected hazards linked to the ingredients. The EWG VERIFIED™ mark means a product meets EWG’s strictest criteria for transparency and health.
The Skin Deep data availability rating reflects the number of scientific studies about the product or ingredient in the published scientific literature.
