The present invention relates to a detergent composition comprising alkali metal carbonate, a chelant selected from the group consisting of MGDA, alkali metal tripolyphosphate, GLDA, and mixtures thereof, alkali metal percarbonate, and a peroxidation catalyst, wherein the molar ratio of chelant to alkali metal percarbonate is in the range of 1.8 to 3.4. The detergent composition is particularly suited for the removal of tea and coffee stains.

Stain removal through novel oxidizer and chelant combination

Detergent compositions and methods of preparing and using the detergent compositions are disclosed. The detergent compositions comprise a polymer system comprising at least one polycarboxylic acid polymer, copolymer, or terpolymer, an alkalinity source comprising an alkali metal carbonate, a nonionic surfactant and water. The detergent compositions are suitable at alkaline pH and reduce or prevent scale formation, improve soil dispersion, and provide effective detergency.

High alkaline warewash detergent with enhanced scale control and soil dispersion

The invention includes ware detergent compositions which provides superior cleaning and removal of oily and fatty soils, without the production of excessive foam. According to the invention applicants have discovered that use of a quaternary cationic surfactant in combination with a nonionic low foaming surfactant can provide oily soil removal from ware that is superior to traditional warewash detergent formulations. Compositions for alkaline, preferably solid, warewash detergents are disclosed, as well as their use in dish machines and methods of manufacture.

Low-foaming warewash detergent containing mixed cationic / nonionic surfactant system for enhanced oily soil removal

Solid detergent compositions designed to maintain solid integrity throughout production of the pressed solid, during mechanical conveying and during ejection from molds, are disclosed. Solid detergent compositions having unexpected immediate block hardness without a curing step are provided by inclusion of a hardness additive composition comprising a synergistic ratio of polycarboxylic acid polymer chelants to aminocarboxylate chelants. Methods of making solid detergent compositions and solid detergent compositions having at least substantially similar cleaning performance to solid detergent compositions without the hardness additive composition are also provided.

Hardness additives comprising an acrylate/aminocarboxylate mixture and block detergents containing said mixture to improve edge hardening

Solid detergent compositions for dishwashing or warewashing compositions and applications of use are disclosed. In particular, solid caustic-based compositions that do not require a traditional dispenser for controlled rate of release over multiple cycles are disclosed. Compositions, methods of employ and cleaning using the same are disclosed.

Solid controlled release caustic detergent compositions

Detergent compositions designed to prevent aluminum discoloration while providing high cleaning performance on soils and stains are disclosed. Detergent compositions substantially free of nitrilotriacetic acid (NTA) are disclosed. Methods of using the detergent compositions are also disclosed.
