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.

##STR00002##

wherein each R.sup.3 is independently selected from a hydrogen and a —C(O)CH.sub.3 group; and 10 to 65 wt % of structural units of formula III

##STR00003##

wherein each R.sup.4 is independently selected from a hydrogen and a —CH.sub.3 group; and wherein at least one of R.sup.1 and R.sup.2 is a C.sub.1-3 alkyl group in at least 1 mol % of the structural units of formula I in the antiredeposition agent; wherein the antiredeposition agent has a lactone end group and wherein the antiredeposition agent has a weight average molecular weight of 1,500 to 6,000 Daltons.

Rinse aid compositions, methods of use, and methods of making said composition are disclosed. The rinse aid compositions can be solid or liquid. The rinse aid compositions comprise a defoamer, a sheeting agent, and a terpolyer of maleic, vinyl acetate, and ethyl acrylate. Preferred sheeting agents include one or more alcohol ethyoxylates. Preferred defoamer components include a polymer compound including one or more ethylene oxide groups. The solid rinse aid compositions are preferably substantially free of sulfate and sulfate-containing compounds.

A method of making a detergent composition including the following steps in the recited order: providing an aqueous composition comprising a citrate salt; lowering the pH by adding a first, un-neutralized or partially neutralized, polyacrylic acid having a weight average molecular weight in the range of 1000 to 6000 to form a second mixture; increasing the pH by adding alkali metal carbonate and/or alkali metal bicarbonate to form a third mixture; and adding a second polyacrylic acid having a weight average molecular weight in the range of 1000 to 6000 to form a fourth mixture; wherein the detergent composition is preferably an automatic dishwashing detergent composition or a laundry detergent composition.

A laundry detergent formulation is provided that is formed as an aqueous blend of surfactants, enzymes, builders, and soil release polymers to inhibit soil re-deposition back onto other clothing or elements of the washing machine. The detergent formulation also contains additives with properties that impart a treatment to fabrics that inhibits future soil deposition onto the clothing with continued use. The detergent formulation provides cleaning of heavy duty grease and automotive soils from clothing surfaces that is superior to current detergent products.

The present disclosure relates to high alkaline cleaners, cleaning systems and methods for removing polymerized zero trans fat soils. The high alkaline cleaner of the present invention generally includes one or more alkaline wetting and saponifying agent(s), a chelating/sequestering system and a surface modifying-threshold agent system. In various embodiments, the cleaners may include, at least one cleaning agent comprising a surfactant or surfactant system and/or a solvent or solvent system and/or a cleaning booster such as a peroxide or sulfite type additive. The cleaners may also include one or more components to modify the composition form and/or the application method in some embodiments. All components described above may also be optimized optionally, to provide emulsification of a composition (both as a usable product or a concentrate that can be diluted to form a usable product). The use of the high alkaline cleaner of the present invention has demonstrated enhanced cleaning characteristics especially at higher temperatures (100° F. to about 300° F.) but also shows enhanced cleaning at ambient temperatures.

Industrial 2-in-1 cleaning compositions providing both detergency and rinseability in a single cleaning composition comprising a polymer are disclosed. Alkali metal carbonate-based cleaning compositions and methods of both making and using the same provide user-friendly, solid, detergent compositions without the need for using a separate rinse aid composition. The compositions and methods are particularly well suited for use in industrial cleaning using alkali metal carbonate compositions that beneficially provide cleaning and rinseability in the rinse cycle.

Lipophilic super-absorbent swelling gels have been developed that will not only absorb the oil and grease from these machine parts, but will also act as an automated sweeper due to the self-generating mechanical force of the gel. An octadecylacrylate-co-ethylene glycol dimethacrylate (ODA-co-EGDMA) tetraalkylammonium tetraphenylborate lipophilic polyelectrolyte gel (EG-18) and poly(stearylacrylate-co-ethylene glycol dimethacrylate) (SA-co-EGDMA) neutral gel (NG-18) were evaluated for swelling and oil sorption capacity. NG-18 and EG-18 gels removed particulate contaminants and absorbed oils and grease on metal and non-metal surfaces without causing abrasion. The gels are also recyclable. The cleaning ability of the gels was compared with the standard solvent cleaner trichloroethylene (TCE) following ASTM G122-96(2008) test methods and MIL-PRF-680B procedure with MIL-PRF-10924 test grease. Polymer gel cleaners exhibited analogous extent and rate of cleaning as the TCE. These recyclable superabsorbent polymer cleaners will allow drastic reduction in the use of VOC containing solvents and HAP release.

Liquid acidic hard surface cleaning composition comprising certain copolymers provide good limescale removal and long lasting shine to a broad range of surfaces. Moreover, when formulated with suitable acid systems, they also provide improved surface safety over more delicate surfaces.

An automatic dishwashing composition is provided, comprising: a dispersant polymer blend, comprising an acrylic acid homopolymer; and a copolymer of acrylic acid and a sulfonated monomer; wherein the dispersant polymer blend has a blend ratio of the acrylic acid homopolymer to the copolymer of 3:1 to 1:3; a surfactant; a builder; and optionally, an additive.
