LINEAR ALKYLBENZENE

GENERAL

Linear alkylbenzene (LAB), a basic petrochemical intermediate derived by alkylation of benzene starting from n-paraffins feedstock, is used to produce LAS (Linear Alkylbenzene Sulphonate).

APPLICATION

Linear alkylbenzene sulfonates (LAS) for laundry detergents, light-duty dishwashing liquids, industrial cleaners, for household cleaners.
