Abstract (en)
A detergent composition for washing soiled materials, notably fabrics is based on alkyl orthoxylene sulphonate as detergent active. Good detergency is achieved by restricting electrolyte concentration so that there is an ionic strength of not more than 0.05 mole/litre in the wash liquor. A detergent composition for this purpose contains not more than 60% by weight of water-soluble alkali metal salts and preferably contains zeolite as water-insoluble builder. Alternatively or additionally a second surfactant, which is soluble in electrolyte solution is included, in which case ionic strength may be greater than 0.02 mole/litre and there is synergy between the surfactants.
