Sodium Lauryl Ether Sulfate CAS#68585-34-2
Sodium Lauryl Ether Sulfate (SLES)—also known as Sodium Laureth Sulfate or AES (Alcohol Ether Sulfate)—has the chemical formula CH₃(CH₂)₁₁(OCH₂CH₂)ₙOSO₃Na and CAS number 68585-34-2. It typically appears as a white to pale yellow viscous liquid or paste; common commercial forms include a paste with 70% active matter or a liquid with 28% active matter. It is readily soluble in water, forms stable foam in aqueous solutions, and has a pH (1% aqueous solution) ranging from 6.5 to 9.5. This product is widely used in personal care items (such as shampoos, body washes, and hand soaps) as well as in dishwashing detergents, laundry detergents, industrial cleaners, emulsifiers, and foaming agents. Standard packaging options include 200L plastic drums (200 kg), 1000L IBC totes (1000 kg), or smaller plastic containers. It should be stored in a cool, dry, and well-ventilated area away from direct sunlight. The shelf life is typically 24 months from the date of manufacture, and the HS code is 3402.11.00.
