Частые вопросы по продукту
What is Sodium Lauryl Sulfate Granular CAS 151-21-3?
A: Sodium Lauryl Sulfate Granular CAS 151-21-3 is a granular or needle-form anionic surfactant with the formula C12H25NaO4S and molecular weight 288.38 g/mol. It is also known as SLS, SDS or K12.
What is the advantage of the granular or needle form over powder?
A: The granular form reduces airborne dust during handling and dosing, which improves workplace cleanliness and safety. It also has better flowability while retaining the same foaming, emulsifying and detergency properties as powder grades.
What are the main applications of SLS?
A: SLS is used in shampoos, body washes, toothpaste, household detergents, industrial cleaners and textile or polymer processing. It provides foam, wetting, emulsification and cleaning performance in water-based formulations.
What specifications are important for Sodium Lauryl Sulfate?
A: Key parameters include active matter, petroleum-ether-soluble material, inorganic salts, moisture, pH and whiteness. High-purity grades with low salt content are generally preferred for personal care and oral care applications.
Is Sodium Lauryl Sulfate biodegradable?
A: SLS is readily biodegradable under standard aerobic conditions and is widely used in cleaning products. For environmental and regulatory claims, confirm the specific grade and test data for the target market.
