Linear alkylbenzene sulfonate (LAS) is a type of anionic surfactant commonly used in household and industrial cleaning products. It is derived from linear alkylbenzene, which is produced from petroleum. LAS is effective in breaking down grease and dirt, making it a popular ingredient in laundry detergents and dishwashing liquids. Due to its excellent cleaning properties, LAS is also used in various applications, including personal care products and industrial cleaners. It is biodegradable, which makes it a more environmentally friendly option compared to some other surfactants. However, its production and use are regulated to minimize environmental impact.
