An aqueous liquid detergent composition comprising water, electrolyte and detergent active material in amounts sufficient to form a structuring system capable of suspending particulate solids, said composition further comprising a functional polymer ingredient having an average molecular weight below 2000, provided that when the composition comprises: (a) at least 15% by weight of the detergent active material and from 1 to 30% by weight of a salting-out electrolyte; or (b) contains 5% or more of a swelling clay; and then the average molecular weight of the polymer ingredient is less than 1000; and when the functional polymer material comprises 0.5% by weight or less, relative to the total composition, of an acrylate or methacrylate polymer having a molecular weight of 500 or greater, the detergent active material comprises a synthetic anionic surfactant and a soap and the composition is free from pentasodium triphosphate; then the composition is also substantially free from insoluble abrasive; said composition yielding no more than 2% phase separation by volume upon storage at 25.degree. C. for 21 days.
An aqueous liquid detergent composition substantially free of insoluble abrasive comprising water, electrolyte and from 15 to 50% by weight of detergent active material in amounts sufficient to form a structuring system capable of suspending particulate solids, said composition further comprising from 0.5 to 12.5% by weight of a functional polymer selected from the group consisting of polyethylene glycols, Dextran, Dextran sulphonates, plyacrylates, polymethacrylates, polyacrylate/maleic acid copolymers and salts or part salts thereof, said functional polymer ingredient having an average molecular weight below 2000, provided that when the composition comprises:
