Linear Alkylbenzene (LAB)

CAS# 67774-74-7

Linear Alkylbenzene (LAB) is a clear, colorless organic compound widely used as an intermediate in the production of surfactants. It is manufactured by the alkylation of benzene with linear mono-olefins, ensuring high purity and biodegradability. LAB is a key raw material for producing linear alkylbenzene sulfonate (LAS), the world’s most commonly used synthetic detergent. With stable chemical properties and excellent performance, LAB offers a balance of effectiveness, safety, and cost-efficiency across multiple industries.

Primary Application of Linear Alkylbenzene

Raw material of linear alkylbenzene sulfonate (LABSA), the active ingredient in household detergents, dishwashing liquids, and industrial cleaners. Due to its biodegradability and effective cleaning properties, LAB-based LAS is preferred in both domestic and commercial cleaning formulations. Additionally, LAB finds use in specialty industrial applications such as emulsifiers and agricultural chemicals. Its versatility, performance, and environmental compatibility make LAB an essential component in modern cleaning and chemical solutions.
