CAS No.: 2044-56-6
Lithium dodecyl sulfate is an anionic hydrocarbon surfactant with both surface tension reduction and interfacial adsorption capabilities. Lithium dodecyl sulfate induces low surface viscosity; it forms micelles in aqueous solutions through entropy-driven (low temperature) and enthalpy-driven (high temperature) mechanisms. When acting synergistically with tetrabutylammonium bromide, Lithium dodecyl sulfate exhibits cloud point behavior due to micelle aggregation and phase separation. Lithium dodecyl sulfate can form an adsorption layer at the air-water interface with quantifiable surface excess and minimum area per molecule, and it has higher equilibrium surface tension and foamability compared to other dodecyl sulfate counterion variants. The foam stability of Lithium dodecyl sulfate above its critical micelle concentration is low, and its dynamic surface tension pattern changes dynamically with bubble frequency .

Hel 13-5 is a monomeric, lipophilic, basic amphipathic α-helical synthetic peptide composed of 18 amino acid residues. Hel 13-5 is designed as a substitute for proteins in artificial pulmonary surfactants, and it mimics the interaction between the N-terminal fragment of human pulmonary surfactant protein B and lipids. Hel 13-5 can bind to phospholipids for the development of pulmonary surfactant model systems. Hel 13-5 can be used in studies related to respiratory distress syndrome .
