詳細

詳細

Sodium dodecyl sulfate (SDS) is a conventional anionic surfactant. An amphiphilic surfactant consists of polar hydrophilic head groups and non-polar hydrophobic tail groups. Surfactants are characterized by their ability to form micelles, i.e., their ability to self-aggregate above a critical micelle concentration (CMC). Due to its amphiphilic nature, the surfactant is used as a detergent in industries. They are useful for cleaning, wetting, dispersing, emulsifying, foaming, and antifoaming.

アプリケーション

Sodium dodecyl sulfate used as a surfactant:

• In the synthesis of SiO₂/polystyrene nanocomposite particles by miniemulsion polymerization.
• In the preparation of solid lipid NPs (SLNs) and poly(lactide-co-glycolide) NPs containing OA-Fe₃O₄ as CANs (composite antistatic NPs).
