Description

General description

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.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is used as a surfactant to enhance catalysis.  Click here for more information.

Application

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).
