The invention provides an ampholytic surfactant containing quaternary ammonium salt as well as a preparation method and application of the ampholytic surfactant, and belongs to the field of materials. The amphoteric surfactant containing quaternary material, carrying out alkaline hydrolysis in ammonia water to obtain water-soluble carboxylate, and grafting quaternary ammonium salt groups on amide groups. Due to the existence of the quaternary ammonium salt group, the surfactant has good antibacterial property, and due to the fact that the surfactant has both a cationic group and an anionic group, the surfactant has good antistatic property. In application, the surfactant can be prepared with alkyl sodium sulfonate to obtain a pre-disinfection detergent for sanitary equipment and medical instruments. The surfactant and a thickener aid are dissolved in a solvent according to a certain ratio to obtain an antibacterial antifogging agent. The surfactant can also be added into a tanning agent to improve the antibacterial property of the tanning agent.

The invention relates to dispersants obtained by polymerization of ethylenically unsaturated acids or anhydrides onto mercapto-functionalized polyether polyols, to their use for producing polyol dispersions by acidolysis of polyurethane waste, as well as to the use of the resulting polyol dispersions for producing polyurethanes.
