摘要:
Granular built detergent compositions containing specific mixtures of anionic surfactant alkoxylated nonionic surfactant and water-soluble cationic surfactant. In highly preferred compositions, the anionic surfactant comprises a sulfate or stulfo- nate anionic surfactant or a mixture thereof with a fatty acid soap. Especially preferred compositions comprise a mixture of sulfonate and sulfate anionic surfactants. The compositions provide enhanced oil and grease removal from fabrics together with good clay soil detergency, whiteness maintenance and foam control characteristics under realistic multicycle wash conditions.
摘要:
Granular laundry compositions comprising a particulate mixture of a water-insoluble natural or synthetic silica or silicate, a finely-divided organic peroxy acid bleach precursor, and an alkoxylated nonionic surfactant. The particulate mixture has a pH in 2 % aqueous dispersion of from pH 2 to pH 9. The compositions have improved granular physical characteristics, chemical stability and rate of solution/dispersion characteristics. They are useful in bleach activator, bleaching, detergent and laundry additive compositions.
摘要:
A detergent additive composition in the form of an extrudate comprising 75% to 95% of particulate infusible solids comprising storage-sensitive detergent-additive material and 5 to 25% of ethoxylated nonionic surfactant The storage-sensitive detergent additive material is preferably an organic peroxy acid bleach precursor. When added to detergent compositions, the additive compositions have excellent storage stability and water-dispersibility characteristics.
摘要:
Textile softening detergent compositions comprise a nonionic detergent, a cationic textile softener, builders and a nonionic-type optical brightener, selected from benzoxazole, coumarin, bis(benzimidazolyl) furan and bis-(sulphonamidostyryl)biphenyl types. Preferred compositions also contain a discolouration inhibitor, and are made by spraying a mixture of the nonionic detergent and cationic softener on to spray dried granules comprising at least part of the builders.
