• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis.
• Chemical Composition and Structure: Sodium dodecyl sulfate (SDS or NaDS), also known as sodium lauryl sulfate (SLS), is an anionic surfactant belonging to the alkyl sulfates surfactants. It consists of a 12-carbon atom chain (dodecyl group) attached to a sulfate group, giving it an amphiphilic structure. SDS is synthesized from dodecyl alcohol through a reaction with sulfuric acid, resulting in the formation of dodecyl sulfate, which is then converted to sodium salt using sodium hydroxide.
• Corrosion Inhibition: SDS serves as an efficient corrosion inhibitor for materials such as AZ91 Mg alloy by adsorbing on AlMn intermetallics to suppress micro-galvanic corrosion.
• Emulsion Stabilization: SDS is utilized in the crosslinking of gelatin, where it modifies the surface structure and charge of emulsion droplets by forming electrostatic complexes. This process results in desirable droplet structures with high stability.
• Foaming Agent: SDS is widely employed as a foaming agent in various fields due to its low cost and excellent foaming ability.
• Stabilizer for Fabrication of Magnetic Nanoparticles (MNPs): SDS is used as a stabilizer in the fabrication of MNPs, and these nanoparticles find applications as antibacterial and antifungal agents.
• Effects of Metal Ions on Aggregation Behavior: Sodium dodecyl sulfate's aggregation behavior is influenced by the presence of metal ions such as Europium(III) and Cerium(III). Additionally, the addition of sodium ions to SDS solutions alters critical micelle concentration (CMC) values, with CMC decreasing as the concentration of sodium salts like NaCl, sodium acetate, and sodium propionate increases.
