A bleach composition and a method for bleaching stains is provided, the composition including a C.sub.7 -C.sub.20 aromatic aldehyde and a transition metal salt. Air is employed as source of oxygen which combines with the aldehyde to form the bleach active species. Peroxides, inorganic persalts and bleach precursors are unnecessary elements for the bleach systems of this invention.

Bleaching compositions based on air, uncomplexed transition metal ions

A bleach composition and a method for bleaching stains is provided, the composition including a C.sub.7 -C.sub.20 aromatic aldehyde and an imide, the latter being particularly N-hydroxyphthalimide. Air is employed as a source of oxygen which combines with the aldehyde to form the bleach active species. Peroxides, inorganic persalts and bleach precursors are unnecessary elements for the bleach systems of this invention.

Bleaching compositions and method for bleaching substrates directly with

Detergent compositions, essentially free of chlorine bleach compounds, containing a surfactant, builder, enzyme, peroxygen bleach and from about 0.001% to about 5% by weight polyethyleneimine (PEI) or salts thereof are disclosed. These compositions exhibit controlled and improved bleaching action on stains as well as improved storage stability, fabric safety and whitening/brightening characteristics.

Detergent compositions containing polyethyleneimines for enhanced

Detergent compositions, essentially free of peroxygen or chlorine bleach compounds, containing a surfactant, builder, enzyme and from about 0.001% to about 5% by weight polyethyleneimine (PEI) or salts thereof are disclosed. These compositions provide enhanced removal of organic stains, particularly on polyphenolic stains such as morello juice (cherry juice), blueberry juice, red wine, tea and coffee. Improvement was also demonstrated on certain non-polyphenolic stains such as grass.

Detergent compositions containing polyethyleneimines for enhanced stain

Novel personal product and detergent compositions comprising new and known glycacarbamate, glycaurea compounds or mixtures thereof are disclosed. The personal product compositions exhibit mild cleansing, opacifying/pearlescent and suspending action. The liquid detergent compositions exhibit enhanced viscosity and improved detergency. The powdered detergent compositions exhibit improved flow characteristics and improved detergency. Also, disclosed are novel glycacarbamate and glycaurea compounds which have enhanced water solubility and do not become turbid or produce sedimentation in aqueous compositions as well as an improved method of manufacture.

Compositions comprising glycacarbamate and glycaurea compounds

The present invention relates to novel detergent and/or personal wash compositions comprising glycosylamide surfactants.

Compositions comprising glycosylamide surfactants

The present invention relates to a new class of carbohydrate based nonionic surfactant, i.e., alkyl and alkenyl glycasuccinamide, and a process for their manufacture.

Anionic glycasuccinamide sufactants and a process for their manufacture

Anionic glycasuccinamide surfactants and a process for their manufacture

The present invention relates to novel hydroxy-containing alkyl glycamide surfactants and detergent composition comprising said surfactants. Since they surprisingly provide low foam, these surfactants can be used as cleansing surfactants in applications where low foaming is desirable.

Hydroxy containing alkyl glycamides, low foaming detergent compositions

Laundry detergent compositions containing a detergent surfactant, a detergent builder, and from about 0.1% to about 50% by weight ethylene aspartate cysteate sequestrants or its acid form are disclosed. These compositions provide enhanced removal of organic stains, such as food and beverage stains particularly polyphenolic stains such as wine, blueberry, tea, coffee, morello juice and the like.

Detergent compositions containing ethylene aspartate cysteate (EAC)

Mixed chain alkyl (alkyl glycosid) uronates as nonionic surfactants are disclosed.

Enzymatically stable alkyl (alkyl glycosid) uronates as nonionic

Novel compounds useful as sequestrants as well as builders for detergent compositions and methods for their preparation are disclosed.

Ethylene dicysteate sequestrants and methods for preparation

Ethyene containing cysteate sequestrants and methods of manufacture

Laundry detergent compositions containing a detergent surfactant, a detergent builder, and from about 0.1% to about 50% by weight ethylene dicysteate or its acid form are disclosed. These compositions provide enhanced removal of organic stains, such as food and beverage stains particularly polyphenolic stains such as wine, blueberry, tea, coffee, morello juice and the like.

Detergent compositions containing ethylene dicysteate (EDC) sequestrants

The present invention relates to sulfated polyhydroxy compounds used as anionic surfactants and to processes for their manufacture.
