Sodium octyl sulfate is widely used as a surfactant in various cleaning and personal care products. Its ability to reduce surface tension makes it effective in formulations like shampoos, body washes, and facial cleansers, where it helps to remove dirt and oil from the skin and hair. It is also utilized in household cleaning products, such as dishwashing liquids and laundry detergents, to enhance their cleaning efficiency by breaking down grease and grime. Additionally, it finds application in industrial settings as a wetting agent or emulsifier in processes requiring stable mixtures of oil and water. Its mild nature makes it suitable for use in products designed for sensitive skin.
