Sodium Ethylhexyl Sulfate

Sodium Ethylhexyl Sulfate (SEHS),sulfated surfactantused as asurface tension reducer, thereby enabling the mixing of water with other compounds. It is commonly found incleaning products,cosmetics, andpersonal care products. Additionally, it is an effective compound in products such asemulsifiers,detergents, andshampoos.

What is Sodium Ethylhexyl Sulfate (SEHS)?

Sodium ethylhexyl sulfate is aethylhexyl alcoholreacting with sulfuric acid to form asulfated surfactant. This compound is known for its cleansing and solvent properties and is used in a wide variety of industrial applications. Surfactants help balance molecules between water and oil, allowing these substances to mix. Thus, they can dissolve and remove dirt, oils, and other contaminants from water.

Chemical Properties:

• Chemical Formula:C₈H₁₇NaO₄S
• Molecular Weight:270.28 g/mol
• Physical State:Typically found as acolorless or slightly yellowish liquid.
• Solubility:Highly soluble in water,.
• pH:Exhibits acidic properties, but the pH level is usually adjusted in formulations.
