The present invention provides detergent compositions, essentially free of peroxygen or chlorine bleach compounds, containing one or more surfactants, one or more builders, one or more enzymes and one or more low MW (e.g., 0.8-25 kDa) polyethyleneimine (PEI) polymers or salts thereof, and methods of producing such compositions. The compositions of the invention provide certain benefits in cleaning of textiles (particularly fabrics including clothing), hard surfaces and dishware and utensils, including enhanced removal of certain difficult-to-remove stains such as chocolate pudding and grass, as well as of polyphenolic stains such as cherry juice, blueberry juice, red wine, tea and coffee. The invention also provides methods of using these compositions in laundry, hard surface cleaning and dishwashing applications.

Polymer-containing cleaning compositions and methods of production and use thereof

The present invention provides liquid cleaning compositions useful in cold water and hard water laundry applications, and methods for making and using such compositions. The compositions of the invention use surfactants or surfactant blends, such as &#x3b1;-sulfofatty acid esters or mixtures thereof (optionally along with one or more additional components), that have increased solubility/stability at cold temperatures, at higher-than-usual concentrations, and/or in hard water, with the composition remaining as a clear liquid. In certain embodiments, the compositions of the invention may be provided in the form of a unit dose, for example in a water-soluble pack or pouch. In use, the compositions of the invention result in an enhanced detergency along with a reduced amount of residue remaining in the machine, on laundered garments or cleaned dishware or hard surfaces, and on the body in personal care settings, and demonstrate a longer shelf-life, particularly when stored or used in colder temperatures.

Cleaning formulations with improved surfactant solubility and methods of production and use thereof

A liquid laundry detergent composition comprising from about 0.1% to about 80%, by weight of the composition, of a polyanionic ammonium surfactant; a substantially non-aqueous carrier; and a solid inorganic base having pKa equal to or greater than 10.
