Phosphate esters and sulfonate silicone surfactants are the most common. ANTHONY and others use toluene as the solvent. Alkenyl polyether compounds react with hydrogen-containing silicone oil under the action of a catalyst to synthesize hydroxy silicone oil. Phosphoric acid or P2O5 is used for phosphorylation reaction. A phosphate ester silicone oil with good lubricity and antistatic properties on the fiber was prepared. Later, he used an epoxy silicone oil and an alkyl phosphate salt to prepare a silicone phosphate ester with very good emulsifying ability. Polysiloxane phosphate has both emulsification, foaming and mild washing properties of phosphate groups, non-ionic properties such as the cloud point of polyethers, and the affinity of polysiloxane for skin and hair. BROWN et al. Used a high-temperature condensation reaction of maleic anhydride, sodium sulfite, hydroxyl-terminated polyether, and α, ω-hydroxy silicone oil to prepare a sulfonate polyether polysiloxane surfactant. Good surface activity, hydrophobicity and biodegradability.
