Chinese scientists synthesized cationic polyether-modified silicone quaternary ammonium shampoo conditioners through addition, ring-opening, and quaternization reactions. The mass fraction of unreacted active hydrogen was determined by chemical titration. The compatibility of quaternary ammonium salts with anionic surfactants and their effects on the foaming power of shampoo systems were studied. It was found that polyether-modified silicone quaternary ammonium salts have good compatibility with anionic surfactants. Good foaming in the compound solution.

They studied the effect of cationic polysiloxane quaternary ammonium salt as a hair conditioner on the dry and wet combing effect of hair, and found that the particle size of the emulsion is mainly distributed around 10 μm; and 2% by mass of cationic polysilicon was added to the shampoo Oxyquat quaternary ammonium salt has improved wet carding effect by 28.0% and dry carding effect by 21.2%. It has better conditioning performance than ordinary emulsified silicone oil. Mao Lutian et al. Found in the research on the antibacterial effect of polysiloxane quaternary ammonium salt microemulsions in cosmetics. The polysiloxane quaternary ammonium salt microemulsion The antibacterial rates of ammonium salt emulsion and polysiloxane microemulsion on E. coli were 100.00%, 91.16%, and 84.66%, respectively. The minimum antibacterial concentration of polysiloxane quaternary ammonium salt microemulsion was 1.0 g / L (inhibitory E. coli) and 0.8 g / L (Staphylococcus aureus). Due to its bactericidal and deodorizing effect, it can also be added to antiperspirants. The macromolecules of cationic silicone surfactants contain hydrophobic long-chain polysiloxane links, which makes them excellent in slipperiness and softness; at the same time, they have strong skin and hair properties due to the positively charged quaternary ammonium salt Absorptivity and antistatic conditioning for hair.
