Description
Sodium Dodecyl Sulfate (SDS) Micron Powder – Size: -325 Mesh
Product Description:
Sodium Dodecyl Sulfate (SDS) Micron Powder is a high-purity anionic surfactant widely used in biochemical, pharmaceutical, and industrial applications. With a particle size of -325 mesh and ACS reagent grade quality, this white to slightly yellowish powder is well-suited for use in laboratory research, protein electrophoresis (SDS-PAGE), and emulsion stabilization.
Its chemical formula C₁₂H₂₆O₄SNa gives SDS both hydrophobic and hydrophilic character, enabling it to lower surface tension and solubilize hydrophobic molecules in aqueous environments. Due to its excellent water solubility and high purity (≥99.5%), SDS is also used as a detergent, dispersant, and emulsifier across industries from cosmetics to material science.
