Abstract
An aqueous laundry prewash composition includes a cosurfactant system with a hydrophobic nonionic surfactant and a hydrophilic nonionic surfactant providing balanced detergency, a hydrotrope for stabilizing the cosurfactant system, a thickener and water forming the balance of the composition. A thickened aqueous laundry prewash composition is also disclosed including a surfactant system, water and a thickener being xanthan gum to develop a pourable product wherein shear caused by dispensing of the composition tends to reduce its viscosity. An aqueous laundry prewash composition thickened in a similar manner maintains in suspension an insoluble particle component to further enhance prewash characteristics.
