Benzalkonium Chloride is a quaternary ammonium compound used as a disinfectant, sanitizer, and preservative in various applications.

It is commonly used in surface disinfectants, hand sanitizers, water treatment, pharmaceutical formulations, and personal care products.

In low concentrations, it is generally safe for skin contact, but prolonged or repeated exposure to higher concentrations may cause irritation.

Store it in a cool, dry place, in a tightly sealed container, away from heat and direct sunlight.

It is biodegradable under certain conditions, but disposal should follow environmental regulations to prevent aquatic toxicity.
