Sodium Lauryl Sulfate

⭐ Sodium Lauryl Sulfate (SLS)

Sodium Lauryl Sulfate (SLS) is a highly effective anionic surfactant known for its excellent emulsifying, foaming, and water-solubility properties. It is biodegradable, alkali-resistant, hard-water resistant, and maintains strong stability across a wide pH range. With its ease of synthesis and cost-effective nature, SLS has become one of the most widely used surfactants in both consumer and industrial applications.

SLS is extensively utilized in cosmetics, personal care products, detergents, textiles, papermaking, lubrication, pharmaceuticals, construction materials, chemicals, and oilfield industries. In addition to industrial applications, SLS also plays an important role in research, including studies on anionic–cationic surfactant systems, micellar catalysis, and molecular self-assembly structures.

Enhanced Application Insights

Manufacturers prefer SLS for its:

High foaming ability, ideal for toothpaste, shampoos, and facial cleansers

Strong detergency and degreasing performance, making it suitable for household and industrial cleaning

Excellent wetting power, widely used in textile processing and paper pulping

Compatibility with other surfactants, improving formulation flexibility

Stable performance in high-alkaline systems, suitable for industrial degreasers and construction materials

Reliable rheology and viscosity control, beneficial for liquid detergents and personal-care formulations

SLS is also valued in scientific studies for its ability to form micelles, vesicles, and ordered molecular aggregates, making it a model surfactant for research in colloids, catalysis, and materials science.
