Core Characteristics

1. Structural FeaturesLAS is composed of a hydrophobic dodecyl benzene group and a hydrophilic sulfonate group. This typical amphiphilic structure allows it to effectively reduce the surface tension of water, penetrate into the gaps between dirt and the surface of objects, and then peel off and disperse dirt in water.
2. Performance AdvantagesIt has good hard water resistance and can maintain stable performance in water containing calcium and magnesium ions. With high cost-effectiveness, it is one of the most widely used anionic surfactants globally. In addition, it has good biodegradability, meeting the basic requirements of environmental protection.
3. Safety ReminderLAS has mild irritation to skin and mucous membranes. Long-term direct contact may lead to dry and rough skin. Therefore, corresponding protective measures should be taken during industrial operations.

Main Application Fields

1. Household Cleaning ProductsIt is the core raw material of laundry powder, laundry detergent and dishwashing liquid, accounting for 10%–30% of the formula. It can effectively remove oil stains, dust and protein-based dirt on clothes and tableware, and has stable foam performance to meet daily cleaning needs.
2. Industrial Cleaning and Textile IndustryIn the industrial field, it is used to prepare metal cleaners, floor cleaners and boiler scale removers, which can remove heavy oil stains and rust on the surface of industrial equipment. In the textile industry, it serves as a scouring agent, wetting agent and leveling agent, helping to remove sizing agents and impurities on fibers and improving the uniformity of fabric dyeing.
3. Agricultural ChemicalsAs an emulsifier and dispersant in pesticide formulations, it helps insoluble pesticide active ingredients disperse evenly in water to form a stable suspension. This improves the adhesion and permeability of pesticides on crop surfaces, thus enhancing the pesticide effect.
4. Other FieldsIn the papermaking industry, it is used as a deinking agent to remove ink from waste paper and improve the whiteness of recycled pulp. In the mining industry, it acts as a flotation agent to separate useful minerals from gangue. It can also be used as a component of water-based coatings to improve the dispersion of pigments and fillers.
