Key Features
Superior Surface Activity：With a low critical micelle concentration (CMC) of approximately 8.1×10⁻³ mol/L, SLS rapidly reduces the surface tension of water, enabling efficient wetting, foaming, and oil - water separation. Its amphiphilic structure, featuring a hydrophilic sulfate head and a hydrophobic dodecyl tail, allows it to interact effectively with both polar and non - polar substances.
High Purity：Manufactured through a stringent multi - step process, our SLS product consistently maintains a purity level of ≥95%. Rigorous quality control measures ensure minimal impurities, guaranteeing stable performance and reliability in various applications.
Versatile Compatibility：SLS demonstrates excellent compatibility with a wide range of raw materials, including polymers, dyes, and other surfactants. This property makes it an ideal additive for formulating complex mixtures in industries such as cosmetics, textiles, and pharmaceuticals.
Stable Performance：It performs stably across a broad pH range (pH 5 - 9) and temperature conditions (up to 60°C), retaining its surface - active properties even in hard water environments.
Application
Personal Care Products：
A staple ingredient in shampoos, body washes, and toothpastes, SLS provides rich lather and powerful cleansing capabilities. In toothpaste, it effectively removes dental plaque and stains while enhancing the overall cleaning experience.
Industrial Cleaning：
Used in industrial detergents, degreasers, and car wash soaps, SLS breaks down tough grease, oil, and dirt on various surfaces, ensuring thorough cleaning.
Textile and Dyeing：
Functions as a dispersant and leveling agent in textile dyeing processes, preventing dye aggregation and ensuring uniform color distribution on fabrics.
Biochemical Research：
Essential in SDS - PAGE (Sodium Dodecyl Sulfate - Polyacrylamide Gel Electrophoresis) for protein separation and molecular weight determination. SLS denatures proteins and imparts a uniform negative charge, enabling accurate electrophoretic analysis.
Emulsion Polymerization：
Acts as an emulsifier in the production of polymer emulsions, stabilizing monomer droplets and facilitating the formation of high - quality latex products, such as polystyrene latex.
