General description

Tetradecyl sulfate sodium salt is a detergent-like sclerosant.

Application

Tetradecyl sulfate sodium salt (Sodium tetradecyl sulphate) has been used:
  • to investigate the effects of sclerosant foam preparation and composition on foam structure, the time course of liquid drainage and foam coarsenin
  • in sclerotherapy of telangiectases and reticular veins
  • in situ studies of self-assembled monolayers of adsorbed cationic or anionic surfactant molecules on atomically flat H-terminated Si(111) surfaces in aqueous solutions

Hypoxia and limited vascularization inhibit bone growth and recovery after surgical debridement to treat osteomyelitis. Similarly, despite significant efforts to create functional tissue-engineered organs, clinical success is often hindered by insufficient oxygen diffusion and poor vascularization. To overcome these shortcomings
