The chemical industry relies on precise identification and consistent quality for its raw materials. CAS number 151-21-3 unequivocally identifies Sodium Dodecyl Sulfate (SLS), a critical anionic surfactant. Understanding the technical specifications and chemical properties associated with this CAS number is crucial for formulators and procurement specialists. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer in China, provides Sodium Lauryl Sulfate (SDS) that rigorously adheres to these technical benchmarks.

Sodium Dodecyl Sulfate, with the chemical formula C12H25NaO4S, is characterized by its anionic nature, meaning it dissociates into a sodium cation (Na+) and a dodecyl sulfate anion (C12H25SO4-) in aqueous solutions. This anion is responsible for its surface-active properties. The dodecyl chain provides the hydrophobic tail, while the sulfate group forms the hydrophilic head, enabling it to reduce surface tension and perform functions like emulsification, foaming, and detergency.

Key specifications for SLS that purchasers often scrutinize include Appearance, Active Matter content, pH, Unsulfated Matter, Sodium Chloride, Sodium Sulphate, Iron content, Color, and Foaming Volume. Our product from NINGBO INNO PHARMCHEM CO.,LTD. typically presents as a White powder or needle, with an Active Matter content generally exceeding 92%. The pH of a 1.5% aqueous solution usually falls within the 7.5-10.5 range, indicating its alkaline nature. Low levels of unsulfated matter, sodium chloride, and iron are indicative of high purity, which is vital for sensitive applications in pharmaceuticals and cosmetics.

The Foaming Volume is another critical parameter, often measured in millimeters. A higher foaming volume signifies better lathering capabilities, which is highly desirable in products like shampoos and soaps. Our SLS consistently demonstrates excellent foaming volumes, confirming its efficacy. Moisture content is also kept to a minimum, typically below 5.0%, ensuring product stability and preventing clumping during storage and handling. For those looking to buy Sodium Dodecyl Sulfate with assured quality parameters, our offerings are designed to meet these exacting requirements.
