Overview
Linear Alkylbenzene Sulfonate (LAS) is a synthetic anionic surfactant derived from linear alkylbenzene. It is widely used in the production of detergents and cleaning products due to its effective foaming and cleaning properties. LAS is biodegradable, making it a preferred choice in environmentally conscious formulations. LAS is typically produced through the sulfonation of linear alkylbenzene, resulting in a versatile surfactant that performs well in both hard and soft water. Its chemical structure allows it to reduce surface tension, enhancing the removal of dirt and grease from surfaces.
Physical and Chemical Properties
LAS is a viscous liquid with a light yellow to brown appearance. It has a density of approximately 1.06 g/cm³ and is highly soluble in water and polar solvents. The compound decomposes before reaching its boiling point, requiring careful handling during industrial processes. Key properties of LAS include its high foaming capacity, excellent detergency, and biodegradability. These characteristics make it suitable for a wide range of cleaning applications, from household detergents to industrial cleaners. Its effectiveness is maintained in various water hardness levels, ensuring consistent performance.
Main Applications
LAS is primarily used in the formulation of detergents, including laundry powders, liquid detergents, and dishwashing liquids. Its ability to emulsify oils and grease makes it ideal for industrial cleaners and degreasers. In addition to cleaning products, LAS is used in textile processing, agriculture, and oilfield chemicals. Its surfactant properties enhance the wetting and dispersing capabilities of formulations, improving overall efficiency in these applications.
Safety and Storage
LAS should be handled with care to avoid skin and eye irritation. Protective equipment such as gloves and goggles is recommended during use. The compound should be stored in a cool, dry place away from oxidizing agents to prevent degradation. Spills should be contained and cleaned up immediately to prevent environmental contamination. Proper disposal methods should be followed to comply with local regulations and minimize ecological impact.
B2B Procurement Guide
When procuring LAS, B2B buyers should verify supplier credentials and ensure compliance with environmental and safety standards. Quality control measures, such as testing for purity and consistency, are essential to meet application requirements. Buyers should also consider the form of LAS (liquid or powder) and packaging options (bulk or drums) based on their production needs. Negotiating long-term contracts can provide cost advantages and supply stability.
