A liquid laundry detergent composition comprising: (a) from about 0.1% to about 80%, by weight of the composition, of a polyanionic ammonium surfactant; (b) a liquid carrier; (c) wherein the composition is substantially free of bases having pKa equal to or greater than 10, other than nitrogen-based bases.

Liquid laundry detergent with polyanionic ammonium surfactant

A pretreater or laundry additive composition which removes stains and as a laundry additive, whiten fabrics are described herein. The compositions contain 0.1 to 20 wt. % of a nonionic surfactant, 0.1% to 10 wt. % of a hydrophobically modified polymer and less than about 5 wt. % of an anionic soap. Methods of using the composition are also described.

Method of pretreating stained fabrics with pretreater or laundry

The present invention relates to pretreater or compositions in stick form which remove stains. The compositions contain 30 to 80 wt. % of a nonionic surfactant, 1 to about 20 wt. % of an anionic soap, and 0.1% to 10 wt. % of a hydrophobically modified polar polymer. A method of using the composition is also described.

Stick pretreater compositions containing hydrophobically modified polar

Isotropic liquid detergent composition comprises specific soil antiredeposition polymers containing a hydrophilic backbone and monomer with hydrophobic side chains. When the molar ratio of the number hydrophilic groups to number of hydrophobic groups on said polymers is below certain critical levels, it has been unexpectedly found that the stability (i.e., clarity) of the composition remarkably increases. The solubility of the polymer is further dependent on the type and amount (minimum required) of hydrotrope; surfactant type and levels; and minimum electrolyte levels.

Isotropic liquids comprising hydrophobically modified polar polymer

Isotropic liquid detergent composition comprises specific soil antiredeposition polymers containing a hydrophilic backbone and hydrophobic side chain; and aliphatic hydrocarbon oils. When the molar ratio of hydrophilic groups of the backbone to number of hydrophobic groups attached to the backbone is below certain critical levels; and aliphatic hydrocarbon oil of defined molecular weight (MW) range are incorporated in the formulation; it has been unexpectedly found that the stability (i.e., clarity) of the composition remarkably increases in such oil containing compositions.

Isotropic liquids comprising hydrophobically modified polar polymers

An aqueous liquid detergent composition containing a nonionic surfactant, a builder, a particular hydroxypropyl methylcellulose ether and optionally an anionic surfactant is disclosed having unusual stability, especially at low temperatures. The hydroxypropyl methylcellulose is characterized as having 28-30% methoxyl and 7-12% hydroxypropyl substitution with molecular weight from 5-250 cps nominal viscosity in 2% aqueous solution at 68.degree. F.

Liquid detergent compositions containing hydroxypropyl methylcellulose

A detergent composition has been discovered that imparts improved soil shield properties to synthetic fabrics. The composition comprises:
