A laundry detergent composition contains a surfactant system consisting wholly of anionic surfactant, or of anionic and nonionic surfactants in a ratio at least 0.9:1, a detergency builder, and a soil release polymer which is a defined water-soluble or water-dispersible sulphonated non-end-capped polyester, for example, of terephthalic acid, isophthalic acid, sulphoisophthalic acid and ethylene glycol.

Detergent compositions containing soil release polymers

A laundry detergent composition contains organic surfactant, zeolite MAP builder, and a soil release polymer which is a defined water-soluble or water-dispersible sulphonated non-end-capped polyester, for example, of terephthalic acid, isophthalic acid, sulphoisophthalic acid and ethylene glycol.

A water-soluble copolyester comprising units of a polyglycol or capped polyglycol (for example, polyethylene glycol or polyethylene glycol methyl ether), an aromatic dicarboxylic acid (for example, terephthalic acid) and at least 30 mole % of a polyol having at least three hydroxyl groups (for example, glycerol), but free of ethylene glycol units, is a highly effective soil release polymer for use in detergent compositions. The aromatic dicarboxylic acid units may include units of a sulphonated aromatic dicarboxylic acid (for example, sulphoisophthalic acid).

Soil Release Polymers and detergent compositions containing them

An aqueous structured liquid detergent composition comprising detergents active materials and a peroxygen bleach compound, said detergent composition showing less than 25%, preferably less than 10%, more preferably less than 5% volume increase while stored at a temperature between 20.degree. and 37.degree. C. for three months after preparation.
