  • Patent number: 5560862
    Abstract: 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.

  • Patent number: 5559089
    Abstract: 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.

  • Patent number: 5545350
    Abstract: 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.

  • Patent number: 5536421
    Abstract: 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.

  • Patent number: 5520835
    Abstract: 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.

  • Patent number: 5185088
    Abstract: 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.
