A series of dihydromyrcenol-type trisiloxane surfactants(Sxy) were synthesized by hydrosilylation from 1,1,1,3,5,5,5-Heptamethyltrisiloxane and dihydromyrcenol-polyether catalyzed by Pt-PMVS. The structures of the products were characterized by means of FT-IR and 1H-NMR. We studied their surface and interface properties, compared with the marketing available trisiloxane surfactant BD-3077. The results showed that Sxy could reduce the surface tension of water down to 23 mN/m, a little higher than BD-3077(21 mN/m). The cloud point of S36, S39 and S312 solution(mass fraction 0.5%) were higher than 85 ℃. Sxy showed better stability in hydrolysis resistant experiments than BD-3077.
