Lithium dodecyl sulfate
Based on 1 Customer Validation
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.

Biological Activity
Lithium dodecyl sulfate (1-50 mM) has the lowest foam stability among tested dodecyl sulfate counterion variants, measuring 10 min at 1 mM (below cmc) and ~20 min at 25 mM (above cmc), due to labile micelles that do not enhance foam stabilization[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (9.18 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (9.18 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
