The subject invention involves high moisture containing bar compositions comprising required amounts of a borate compound. The borate compound structures water in the bar thereby enabling the retention of high amounts of moisture without compromising bar properties.

High moisture retaining bars compositions comprising borax as water structurant

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

A method for bleaching laundry and household surfaces is provided which iudes preparing a wash medium with a bleaching composition incorporating polyoxometalates and being free of any effective amount of a bleaching agent such as hydrogen peroxide, organic peracids, inorganic peracids, organic persalts, inorganic persalts, Caro's acid, Caroates and mixtures thereof. A second step involves contacting a stained substrate such as a fabric, kitchenware or a household hard surface for a time and in an amount sufficient to remove the stains. Air is employed as a primary source of oxygen atoms for bleaching.

Bleaching with polyoxometalates and air or molecular oxygen

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.
