Applications:LAS has good ability to remove and keep particles in dispersion. This is utilized in detergents for textile to remove inorganic dirt like earth. The alkyl chain of the molecule adhere to the solid surface that mostly has a faint negative charge while the likewise negatively charged sulfonic group tries to reach as far out as possible into the water phase and by this keeps the particle in dispersion. LAS are stable against oxidation making them suitable to use in mixtures containing oxidants like e. g. bleaching agents. They do not work well in hard water where water insoluble calcium soaps are precipitated. This is compensated by using them in mixtures together with softening substances and other surfactants. In oil based systems the calcium salts of LAS keep wear and soot particles in dispersion and they are therefore used in motor oil to prevent deposits in the motor.
