Light-duty liquid or gel dishwashing detergent compositions having

Mid-chain branched primary alkyl polyoxyalkylene surfactants useful in laundry and cleaning compositions, especially granular and liquid detergent compositions. These surfactants are also suitable for formulation with other surfactants for the purpose of providing improved surfactant systems, especially for use in detergent compositions which will be used in laundry processes involving low water temperature wash conditions. The present invention also relates to novel mid-chain branched primary alkyl polyoxyalkylene surfactants suitable for use in the surfactant mixtures.

Polyoxyalkylene surfactants

Mixtures of mid-chain branched primary alkyl sulfate surfactants useful in cleaning compositions, especially for lower water temperature applications, alone or formulated with other surfactants for the purpose of modifying the low temperature cleaning properties of the cleaning formulations. The present invention also relates to novel mid-chain branched primary alkyl sulfate surfactants suitable for use in surfactant mixtures.

Mid-chain branched alkyl sulfate surfactants

Mid-chain branched surfactants derived from mid-chain branched primary alkyl hydrophobic groups and hydrophilic groups. The present invention also relates to mixtures of mid-chain branched surfactants useful in laundry and cleaning compositions, especially granular and liquid detergent compositions.

Mid-chain branched surfactants

Mid-chain branched primary alkyl alkoxylated sulfate surfactants useful in laundry and cleaning compositions, especially granular and liquid detergent compositions. These surfactant mixtures are also suitable for formulation with other surfactants for the purpose of providing improved surfactant systems, especially for use in detergent compositions which will be used in laundry processes involving low water temperature wash conditions. The present invention also relates to novel mid-chain branched primary alkyl alkoxylated sulfate surfactants suitable for use in the surfactant mixtures.

Mid-Chain branched Alkoxylated Sulfate Surfactants

Cleaning compositions, particularly automatic dishwashing detergent compositions, comprising a stability-enhanced amylase and bleach-improving materials are provided. More specifically, the invention relates to granular automatic dishwashing detergents which provide enhanced cleaning/bleaching benefits. The automatic dishwashing compositions comprise stability-enhanced amylase enzymes and one or more bleach-improving compounds, such as organic peroxides, quaternary substituted bleach activators, quaternary substituted peracids and manganese or iron bleach catalysts.

Cleaning compositions containing bleach and stability-enhanced enzymes

Bleaching detergent compositions comprising particular bleach activators are provided. Excellent bleaching is secured through the selection of bleach activators which operate successfully under mildly alkaline washing conditions or in the presence of reduced levels of hydrogen peroxide.

Bleaching detergent compositions comprising bleach activators effective

Bleach boosters comprising zwitterionic imines and anionic imine polyions having a net negative charge are disclosed. The bleach boosters increase bleaching effectiveness in lower temperature solutions and demonstrate superior color safety profiles. The bleach boosters are ideally suited for inclusion into bleaching compositions including those with detersive surfactants and enzymes. Also provided is a laundry additive product including zwitterionic imines and anionic imine polyions with a net negative charge as bleach boosters. A method for laundering a fabric employing the bleach boosters of the present invention is also disclosed.

Color-safe bleach boosters, compositions and laundry methods employing

Cleaning compositions comprise a builder material which has substantially improved performance and is significantly less expensive than previous builders. The builder material has improved performance in that it unexpectedly has a high calcium ion exchange capacity and rate, and is easy to handle, process and disperse in washing solutions. The cleaning compositions contain a builder material having at least one crystalline microstructure including a carbonate anion, calcium cation and at least one water-soluble cation, wherein the builder has a particle size diameter within selected ranges for optimal performance. The microstructure should have a sufficient number of anions and cations so as to be 'balanced' or 'neutral' in charge.

Cleaning compositions containing a crystalline builder material in

Improved aqueous bleaching solutions formed by reacting a bleach activator having a perhydrolysis selectivity coefficient of 5 or greater and a low-pH perhydrolysis-efficiency coefficient of 0.15 or higher are provided. More specifically, the invention relates to bleaching solutions which provide enhanced cleaning/bleaching benefits though the selection of bleach activators at mildly alkaline washing solutions or in the presence of reduced-levels of hydrogen peroxide.

Bleaching solutions and method utilizing selected bleach activators

Detergents, especially automatic dishwashing detergents, comprising a stain removal system especially adapted for removal of tea stains, coffee stains and the like. The compositions comprise monopersulfate bleach such as 2KHSO.sub.5 .cndot.KHSO.sub.4 .cndot.K.sub.2 SO.sub.4 in combination with perborate or percarbonate at specific ratios, in combination with certain cationic or quaternary-substituted bleach activators.

Automatic dishwashing detergent having bleach system comprising

Automatic dishwashing detergent compositions, comprising particular quaternary-substituted bleach activators, are provided. More specifically, the invention relates to granular automatic dishwashing detergents which provide enhanced cleaning/bleaching benefits through the selection of quaternary-substituted bleach activators having specific features, such as caprolactam or valerolactam leaving groups and/or the ability to form particular cationic aliphatic peracid structures in solution. Preferred automatic dishwashing compositions comprise amylase enzymes. Included are preferred activator compounds and methods for washing tableware in domestic automatic dishwashing appliances using the activators.
