Product Details & Specifications

Sodium Dodecyl Sulfate (K12)

K12, Sodium Dodecyl Sulfate (C₁₂H₂₅NaO₄S, CAS 151-21-3), is a common anionic surfactant. It appears as a white or light yellow powder or liquid with a slight fatty odor. Highly soluble in water, it reduces surface tension and emulsifies oils. It is relatively stable but decomposes on heating and is combustible when exposed to open flame or high heat.
