A liquid heavy-duty detergent composition comprises a homogeneous solution of 5-20% C 12- C 22 alkane sulphonate, particularly sodium alkane sulphonate, 10-30% poly- or pyrophosphate builder, particularly tetrapotassium pyrophosphate, 1-8% sodium xylene or toluene sulphonate as hydrotrope and 40-85% water, all by weight. Potassium, ammonium and triethanolamine alkane sulphonates are less preferred. The composition may also contain sodium sulphate, anticorrosion agents such as sodium or potassium silicates, anti-redeposition agents such as carboxymethyl cellulose and its sodium salt, viscosity reducers such as ethanol or isopropanol and further detergents such as the anionics sodium lauryl or hexadecyl sulphate sodium sulphates of oxo alcohols, alkyl phenol polyether sulphates, polyether sulphates, fatty acidsoaps or alkylaryl sulphonates, and the non-ionics alkylphenol polyethenoxy compounds and fatty alkanolamides.
