Sodium eicosyl sulfate

Description:
Sodium eicosyl sulfate, with the CAS number 13177-49-6, is an anionic surfactant derived from eicosyl alcohol and sulfuric acid. It typically appears as a white to off-white powder or solid and is soluble in water, forming a viscous solution. This compound is characterized by its long hydrophobic eicosyl chain, which contributes to its surfactant properties, allowing it to reduce surface tension and enhance wetting, emulsifying, and foaming capabilities. Sodium eicosyl sulfate is commonly used in personal care products, detergents, and industrial applications due to its ability to stabilize emulsions and improve the solubility of other ingredients. Additionally, it exhibits good biodegradability, making it a more environmentally friendly option compared to some other surfactants. However, like many anionic surfactants, it can be irritating to the skin and eyes, necessitating careful handling and formulation considerations in consumer products. Overall, sodium eicosyl sulfate is valued for its effectiveness in various applications while being mindful of safety and environmental impact.
