  • Erucyl propyl hydroxysulfobetaine EHSB-40-Henan JIahe Biotechnology Co . . .
    EHSB-40 is a biodegradable betaine type viscoelastic surfactant, which can be used in daily chemical and oil field additives The critical micelle concentration (cmc) at room temperature is 1 6×10~ (-4)mol L
  • Thermal stability of hydroxyl sulfobetaine surfactant in high salinity . . .
    Considering betaine surfactant containing an amide group on the molecule has the characteristics of good foaming performance and low price, thiourea is added into the solution of LHSB to improve its thermal stability
  • Erucamide propyl hydroxysulfonyl betaine
    EHSB-40, a biodegradable sulfobetaine zwitterionic viscoelastic surfactant, excels in thickening, surpassing CAB when blended with AES, AOS, and especially fatty acid soaps It offers low irritation and bactericidal properties, enhancing softness, conditioning, and low-temperature stability in washing products
  • Betaine - SINOPT CHEM
    Widely used in hair and skin cleaning products With perfect foaming, thickening and conditioning performance, and good dispersing calcium soap ability They are widely used in shampoo, bath liquid, hand-washing liquid and industrial cleaning detergent
  • Erucyl propyl hydroxysulfobetaine EHSB-40-Zhonghai Chemical_wholly . . .
    EHSB-40 is a biodegradable betaine type viscoelastic surfactant, which can be used in daily chemical and oil field additives The critical micelle concentration (cmc) at room temperature is 1 6×10~ (-4)mol L
  • Effect of a Hydrophilic Head Group on Krafft Temperature, Surface . . .
    Among the three betaine surfactants, the occupied area (A) increases following the order EDAS < EDAB < EHSB The largest A possessed by EHSB is mainly from the formation of hydrogen bonds between hydroxyl groups and H 2 O molecules
  • EHSB-40 (CAS 164118-71-2) Oilfield Viscoelastic Surfactant
    EHSB-40, a biodegradable sulfobetaine zwitterionic viscoelastic surfactant, excels in thickening, surpassing CAB when blended with AES, AOS, and especially fatty acid soaps It offers low irritation and bactericidal properties, enhancing softness, conditioning, and low-temperature stability in washing products
  • Stability mechanisms of viscoelastic zwitterionic-anionic surfactants . . .
    In this study, a novel viscoelastic surfactant system was developed by combining zwitterionic surfactant erucic acid amide propyl hydroxysulfonyl betaine (EHSB) and anionic surfactant sodium dodecyl sulfate (SDS) to enhance air foam stability without damaging the formation in low-permeability reservoirs
  • Effects of Calcium Ions on the Solubility and Rheological . . . - PubMed
    Effects of calcium ions (Ca 2+) on the solubility, aggregate structure, and rheological behavior of a C22-tailed zwitterionic surfactant, erucyl dimethyl amidopropyl hydroxyl sulfobetaine (EHSB), have been investigated in aqueous solution
  • - Buy Product on Nanjing Xinyue Chemical Co. , Ltd.
    EHSB-40 is a biodegradable betaine-type viscoelastic surfactant, which can be used in daily chemicals and oilfield additives The critical micelle concentration (cmc) at room temperature is 1 6×10-4mol L
