Benzethonium Chloride
Benzethonium chloride is a (synthetic) quaternary ammonium salt that is benzyldimethylamine in which the nitrogen is quaternised by a 2-{2-[p-(2,4,4-trimethylpentan-2-yl)phenoxy]ethoxy}ethyl group, with chloride as the counter-ion. An antiseptic and disinfectant, it is active against a broad spectrum of bacteria, fungi, moulds and viruses. It has a role as an antiviral agent, an antibacterial agent, an antifungal agent, an antiseptic drug and a disinfectant. It is a chloride salt, a quaternary ammonium salt and an aromatic ether. — ChEBI

- Summary: Under the conditions of these 2-year dermal studies, there was no evidence of carcinogenic activity of benzethonium chloride in male or female F344/N rats receiving 0.15, 0.5, or 1.5 mg/kg. There was no evidence of carcinogenic activity in male or female B6C3F1 mice receiving 0.15, 0.5, or 1.5 mg/kg.; Exposure of rats and mice to benzethonium chloride by dermal application in ethanol for 2 years resulted in epithelial hyperplasia in male and female rats and mice and sebaceous gland hyperplasia and ulcers in female rats at the site of application.

- Exposure Routes: The substance can be absorbed into the body through the skin and by ingestion. Source: ILO-WHO International Chemical Safety Cards (ICSCs)
- First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whene Source: CAMEO Chemicals

- Cosmetic Ingredient Review Conclusion: On the basis of the available animal and clinical data, the Expert Panel concludes that Benzethonium Chloride and Methylbenzethonium Chloride are safe at concentrations of 0.5 percent in cosmetics applied to the skin. A maximum concentration of 0.02 percent is safe for cosmetics used in the eye area.
