Sodium lauryl sulfate
DB00815. Background. Sodium Lauryl Sulfate (SLS) is an anionic surfactant naturally derived from coconut and/or palm kernel oil. It usually consists of a mixture of sodium alkyl sulfates, mainly the lauryl. SLS lowers surface tension of aqueous solutions and is used as fat emulsifier, wetting agent, and detergent in cosmetics, …

Aryl Sulfate
Addition of salts decreases the CMC of ionic surfactants because it has a tendency to screen the electrostatic repulsion at the surface of the micelle. In the case of sodium alkyl sulfate with 12 carbon atoms, the CMC decreases to 0.0056 M in 0.01 M NaCl, 0.0015 M in 0.1 M NaCl, and 0.0007 M in 0.3 M NaCl. Increasing the temperature …

Effect of sodium alkyl sulfate chain length on stability: …
Among all SAS molecules considered, the external force of sodium octadecyl sulfate is the largest at P 1 position, while sodium hexylsulfate is the smallest. The external forces required by molecules increase with the increase of alkyl chain length. The longer the alkyl chain is, the stronger the interfacial steric hindrance of the molecule is.
