The present invention relates to detergent compositions comprising an organic surfactant, a non-phosphate detergent builder, an ethylene oxide/propylene oxide block copolymer and a polycarboxylate.

Detergent compositions containing a mixture of an ethylene

An aqueous clear, homogeneous liquid composition is provided for the pretreatment of fabric in advance of laundering. The composition includes a mixture of nonionic surfactants with a respective HLB less than 10 and greater than 10. Also present will be a hydrocarbon solvent and the salt of a C.sub.12 -C.sub.22 fatty acid. One embodiment of the composition is an aerosol mousse discharging as a foam that will a number of times alternately expand and collapse.

Fabric pretreatment cleaning compositions

A detergent is disclosed with an improved mixed surfactant system containing a C.sub.8 -C.sub.18 alkylbenzene sulfonate and a special C.sub.12 -C.sub.18 alcohol ethoxysulfate formed with from 6 to 30 units ethylene oxide and having an average weight of 60-80% ethylene oxide by weight based on non-sulfated alcohol ethoxylate. The total amount of aforesaid surfactant ranges from 10 to 20% and the ratio of sulfonate to sulfate is from 3.5:1 to 1.5:1.
