Natural surfactants
The ever-increasing environmental concern about surfactants triggers an interest in natural surfactant. This review, which has an emphasis on work published since 1998, covers three categories of natural surfactants: amphiphiles produced by yeast or bacteria, amphiphiles containing a natural polar headgroup and amphiphiles containing a natural hydrophobic tail. Microorganisms produce both high ...

متن کاملSolutions with Added Surfactants
solutions with a new experimental chelating solution in infected dentin tubes. Twenty-five specimens were randomly assigned to each of the irrigating solutions. Twenty specimens were used as negative and positive controls. After 21 days of contamination with E. faecalis, the irrigating solutions MTAD, QMiX and Tetraclean NA were delivered into each infected root canal. The solutions were remove...
متن کاملAmino acid-based surfactants
The amino acid-based surfactants contain an amide bond, which may contribute to the selfassembly of the surfactants both at surfaces and in the bulk. In order to assess the importance of this type of intermolecular association, the behavior of sodium lauroyl glycinate and sodium lauroyl sarcosinate were compared. The former surfactant is capable of forming intermolecular hydrogen bonds while th...
متن کاملSurfactants - Surface Active Agents
The definition for a detergent is a cleaning agent. The main cleaning agent used in earlier days was soap. This term means a compound formed from the reaction of a fatty acid with a base such as caustic soda, forming the sodium soap of the acid. The more commonly used cleaning agent in this day and age is the synthetic detergent (SYNDET) which is a formulation such as TIDE or FAB. The essential...
