Fabric softeners having increased performance

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

A method of softening fabrics where the consumer adds an effective amount of a particulate fabric softening composition comprising fabric softener agent to an automatic dosing dispenser with water, seals the dispenser, and places the automatic dosing dispenser into a washing machine at the beginning of the wash process. The mechanical agitation and/or heat of the wash cycle aids in forming a finely divided emulsion/dispersion of fabric softener agent which is then released from the dispenser during the rinse cycle.

Method for using solid particulate fabric softener in automatic dosing

Bleaching compositions, laundry and automatic dishwashing detergent compositions comprising particular quaternary-substituted bleach activators, are provided. More specifically, the invention relates to compositions which provide enhanced cleaning/bleaching benefits though the selection of quaternary-substituted bleach activators having specific leaving groups with a conjugate acid pKa above 13 and with specific ratios of the rate of perhydrolysis to the rate of hydrolysis and the rate of perhydrolysis to the rate of diacylperoxide production. Included are preferred activator compounds and methods for washing fabrics, hard surfaces, and tableware using the activators.

Quaternary substituted bleach activators

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.

Automatic dishwashing compositions comprising quaternary substituted

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

Bleaching compositions, laundry and automatic dishwashing detergent compositions comprising multiple-substituted bleach activators which have at least one quaternary nitrogen atom, are provided. More specifically, the invention relates to compositions which provide enhanced cleaning/bleaching benefits though the selection of multiple-substituted quaternary bleach activators having specific leaving groups with a conjugate acid aqueous pK.sub.a above 13 and with advantageous ratios of rate of perhydrolysis to rate of hydrolysis and of rate of perhydrolysis to rate of diacylperoxide production. Included are preferred activator compounds and methods for washing fabrics, hard surfaces, and tableware using the activators.

Multiple-substituted bleach activators

Bleaching compositions, laundry and automatic dishwashing detergent compositions comprising multiple-substituted bleach activators which have at least one quaternary nitrogen atom,, are provided. More specifically, the invention relates to compositions which provide enhanced cleaning/bleaching benefits though the selection of multiple-substituted quaternary bleach activators having specific leaving groups with a conjugate acid aqueous pK.sub.a above 13 and with advantageous ratios of rate of perhydrolysis to rate of hydrolysis and of rate of perhydrolysis to rate of diacylperoxide production. Included are preferred activator compounds and methods for washing fabrics, hard surfaces, and tableware using the activators.

Automatic dishwashing detergents are provided in convenient, compact form without chlorine bleaches or phosphate builders. Thus, monopersulfate bleach such as 2KHSO.sub.5.KHSO.sub.4.K.sub.2 SO.sub.4 is used in combination with protease or amylase enzymes and acrylate organic dispersants to provide good cleaning of tableware. Weak builders such as citrate and pH-adjusting agents such as carbonate, bicarbonate and silicate can be present in the composition.

Low-dosage automatic dishwashing detergent with monopersulfate and

Compositions are disclosed containing fabric softener compound having two hydrophobic groups attached to the remainder of the compound through ester linkages (DEQA), said compositions being concentrated and containing viscosity/dispersibility modifiers which are single long chain cationic surfactants, highly ethoxylated nonionic surfactants and/or mixtures thereof. Premixes of the DEQA and viscosity modifiers to lower the viscosity of the molten DEQA are disclosed. Processes for making aqueous liquid compositions from solid particulate compositions containing the DEQA are also disclosed.

Concentrated fabric softener compositions containing biodegradable

Improved detergent compositions, especially granular automatic dishwashing detergents, comprising multiquaternary bleach activators are provided. The bleach activators contain multiple quaternary nitrogen groups, preferably at least three such groups and preferably have at least one quaternary nitrogen group in the peracid-forming portion of the bleach activator as well as at least one quaternary nitrogen group in the leaving-group portion.

Automatic dishwashing compositions comprising multiquaternary bleach

A granular fabric softening composition, which can be added to water to form an aqueous concentrated emulsion, comprising nonionic fabric softener, preferably a fatty alkyl ester of a polyhydric alcohol, and a mono-long-chain alkyl cationic surfactant. In particular, the use of a sorbitan ester with a mono-long-chain alkyl cationic surfactant provides a granular softening agent which can be used to form a highly dispersed, concentrated, aqueous composition which, when added to, e.g., a rinse cycle of a typical washing process, effectively deposits onto fabric from the aqueous bath.
