For chemists and formulators in the B2B sector, a thorough understanding of core chemical ingredients is paramount for successful product development. Sodium Dodecyl Sulfate (SDS), often referred to by its synonyms Sodium Lauryl Sulfate (SLS) or its designation K12, is a prime example of such an essential compound. This anionic surfactant, characterized by its C12 alkyl chain and sulfate head group, possesses a unique combination of properties that make it indispensable in numerous applications, from laboratory research to large-scale industrial production. As a key manufacturer and supplier, we aim to provide the detailed insights chemists need to leverage SDS effectively.

Chemically, SDS (CAS No. 151-21-3) is the sodium salt of dodecyl hydrogen sulfate. Its molecular structure, CH3(CH2)11OSO3Na, imparts amphiphilic characteristics. The long, nonpolar hydrocarbon tail readily interacts with nonpolar substances like oils and greases, while the polar, negatively charged sulfate head group ensures solubility in water and facilitates interaction with polar molecules. This duality is the foundation of its efficacy as a surfactant, enabling it to reduce surface tension, emulsify immiscible liquids, and disperse solids in liquid media.

In laboratory settings, SDS is renowned for its protein-denaturing capabilities. In SDS-Polyacrylamide Gel Electrophoresis (SDS-PAGE), it disrupts the non-covalent bonds within protein structures, causing them to unfold into linear chains. This process linearizes the proteins and coats them with a uniform negative charge, allowing their migration through the gel to be determined solely by their molecular weight. This application is critical for researchers in biochemistry and molecular biology studying protein structure and function. For such specialized needs, sourcing high-purity SDS from a reliable manufacturer is non-negotiable.

Beyond analytical applications, SDS is a workhorse in formulation chemistry. Its excellent detergency makes it ideal for cleaning agents, efficiently removing particulate and oily soils. Its significant foaming ability is highly valued in personal care products like shampoos and soaps, where lather is often equated with cleaning power. Furthermore, its emulsifying properties are crucial for creating stable oil-in-water or water-in-oil emulsions, essential for lotions, creams, and various industrial formulations. When considering the price of Sodium Dodecyl Sulfate, chemists must weigh its performance benefits against its cost-effectiveness for specific applications.
