Linear Alkylbenzene Sulfonate
Linear Alkylbenzene Sulfonate (LAS) is a widely used anionic surfactant recognized for its excellent detergency and emulsifying properties.
Description
Linear Alkylbenzene Sulfonate (LAS), with CAS number 68585-34-2 and chemical formula C18H29NaO3S, is a prominent anionic surfactant derived from linear alkylbenzene. It is characterized by a sulfonate group attached to a linear alkyl chain, which imparts exceptional surface-active properties. LAS is a key ingredient in numerous cleaning formulations due to its high foaming capability, effective soil removal, and good biodegradability. Its amphiphilic nature allows it to solubilize hydrophobic substances in aqueous media, making it highly effective as a wetting agent, emulsifier, and dispersant. The precise molecular structure, particularly the length of the alkyl chain, influences its performance characteristics, such as detergency, solubility, and biodegradability. This material is typically supplied as a viscous liquid or a powder, depending on its specific formulation and counter-ion. Its versatility and cost-effectiveness position it as a staple in both industrial and household detergent applications worldwide.
Applications
Linear Alkylbenzene Sulfonate finds extensive use across various industrial sectors. It is primarily employed in the formulation of household detergents, including laundry powders, liquids, and dishwashing liquids, where it serves as the primary surfactant for effective cleaning and grease removal. Industrially, LAS is crucial in the manufacturing of institutional cleaners, all-purpose cleaners, and car wash detergents. Its emulsifying properties make it valuable in emulsion polymerization processes for the production of plastics and synthetic rubbers. Furthermore, it is utilized in the textile industry as a wetting agent and scourer, facilitating dye uptake and removing impurities. Agricultural applications include its use as an adjuvant in pesticide formulations, enhancing the spread and penetration of active ingredients. Its broad utility stems from its powerful surfactancy and economical profile.
Storage & Handling
Store in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly closed. Avoid contact with strong oxidizing agents. Handle with appropriate personal protective equipment to prevent skin and eye contact. Ensure good industrial hygiene practices are followed.
