Cetrimide is widely used as an antiseptic and disinfectant in various medical and healthcare settings. It is commonly found in formulations for cleaning wounds, treating minor cuts, and preventing infections. Due to its antimicrobial properties, it is effective against bacteria, fungi, and some viruses, making it a key ingredient in surgical scrubs, hand washes, and skincare products. Additionally, cetrimide is utilized in ophthalmic solutions to clean and disinfect the eye area. It is also employed in the preparation of creams and ointments for treating skin conditions like eczema and dermatitis. In industrial applications, it serves as a surfactant and preservative in cosmetics, shampoos, and other personal care products. Its ability to reduce surface tension makes it useful in laboratory settings for cell lysis and protein extraction.
