Key Properties

  • Are more soluble than the dodecylbenzenesulphonates and alky sulphates due to the hydroxy group and the presence of unsaturated links in alkenyl derivatives

  • Good chemical stability can be used in strong acid or alkaline formulations

  • Give excellent cleaning and foaming in hard water

  • Foams well in the presence of sebum

  • Good foam stability

Applications

  • Liquid hand soap

  • Foaming agent for personal care

  • Detergent for household and toiletries

  • Emulsion polymerisation

  • Shampoos - will not strip the hair of natural oils. When used in combination with betaines (Amphokem CAB) or amine oxides (Lansurf CAO) a similar performance to an alkyl sulphate (Kemsurf DSA) can be achieved

  • Liquid dishwashing

  • Firefighting foams
