Description
Sodium 2-ethylhexyl sulfate (CAS 126-92-1) is an anionic surfactant commercially known under trade names including Tergitol 08, NIAPROOF-8, and Tergemist. It carries no assigned E-code and is identified under EC number 204-812-8. The compound is the sodium salt of 2-ethylhexyl sulfuric acid.
In textile and leather processing, it functions as a wetting and penetration agent, reducing interfacial tension to drive aqueous solutions into dense fibrous substrates. In emulsion polymerisation, it acts as both a surfactant and process catalyst, stabilising monomer droplets and controlling particle size distribution during polymerisation reactions.
Sodium 2-ethylhexyl sulfate is supplied as a colourless aqueous solution and as a solid grade depending on application requirements. It falls under REACH regulation and suppliers operating in the EU must hold a compliant Safety Data Sheet. Standard packaging includes drums and IBC containers for industrial volumes.
