FAQ
Sodium dodecyl sulfate (SDS), CAS 151-21-3, is an anionic surfactant with the chemical formula C12H25NaO4S. It is a water-soluble, linear alkyl sulfate known for its strong detergent properties. SDS is widely used in various industries due to its ability to reduce surface tension. It appears as a white, crystalline solid and is commonly found in products like shampoos, cleaning agents, and laboratory reagents. Its molecular structure includes a hydrophobic dodecyl chain and a hydrophilic sulfate group, making it effective in emulsifying and dispersing oils.
Sodium dodecyl sulfate (SDS), CAS 151-21-3, has diverse applications. In pharmaceuticals, it acts as a detergent and emulsifier. Industrially, it is used in cleaning products, foam control, and as a wetting agent. In the food industry, it serves as a foaming agent and stabilizer. It is also employed in research for DNA extraction and as an analytical reagent. Additionally, SDS is found in personal care products like toothpaste and laundry detergents due to its surfactant properties.
Sodium dodecyl sulfate (SDS), CAS 151-21-3, is generally safe when used properly. It is non-toxic in low concentrations but may cause skin or eye irritation. Safety standards require adherence to handling guidelines, such as using gloves and goggles. Inhalation of SDS dust should be avoided, and proper ventilation is essential. Safety data sheets (SDS) outline precautions for safe handling, storage, and disposal to minimize risks in industrial and laboratory settings.
Sodium dodecyl sulfate (SDS), CAS 151-21-3, should be stored in a cool, dry place away from moisture and light. Keep it in a sealed, non-corrosive container to maintain stability. Storage conditions should ensure temperatures below 25°C and humidity levels below 60%. Avoid exposure to incompatible substances. Proper storage extends shelf life and ensures safety during handling and use.
