Described herein is a dishwashing detergent formulation, including

Dishwashing detergent formulations comprising polyaspartic acid and graft polymers based on oligo- and polysaccharides as film inhibiting additives

A cleaning composition comprises the reaction product of A) a chelating component and B) an acidic component different from the chelating component. The chelating component is selected from the group of methylglycine-N&#x2014;N-diacetic acid (MGDA), N,N-bis(carboxymethyl)-L-glutamate (GLDA), nitrilotriacetic acid (NTA), hydroxyethylethylenediaminetriacetic acid (HEDTA), ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), and mixtures thereof. The chelating component is generally a salt or a partial-salt of the respective acid, e.g. Na.MGDA. The B) acidic component and the A) chelating component are reacted in a molar ratio (B:A) of from about 6:1 to about 1:6 to form the reaction product. The cleaning composition further comprises a surfactant component in addition to the reaction product. The cleaning composition is useful for removing and/or preventing spotting and filming on ware surfaces in a dishwater, such as for removing and/or preventing filming and/or spotting on cookware, bakeware, tableware, dishware, flatware, and/or glassware in an automatic dishwasher (ADW).

Cleaning composition for dishwashing

A method of curing a coating composition and a method of forming a cured coating on an automobile component are provided. The coating composition comprises a radical polymerizable compound and an organoborane-amine complex having an organoborane initiator, an amine blocking agent, and water. The method of curing the coating composition comprises the steps of combining the organoborane-amine complex, the radical polymerizable compound, and water to form the coating composition. Carbon dioxide is introduced into the coating composition or into a composition including at least one of the organoborane-amine complex, the radical polymerizable compound, and water prior to forming the coating composition. Carbonic acid is formed in situ within the coating composition through reaction of the water and carbon dioxide. The organoborane-amine complex is decomplexed with the carbonic acid thereby separating the organoborane initiator and the amine blocking agent. The radical polymerizable compound is polymerized using the organoborane initiator in the presence of oxygen.

Method of curing a coating composition comprising a radical curable compound and an organoborane-amine complex

A method of forming a cured coating composition on an automobile component is provided. The method utilizes a coating compound including a radical polymerizable compound and an organoborane initiator and includes the step of applying the coating composition to the automobile component. The organoborane initiator is complexed with a bi-functional noncyclic blocking agent that has a carbon backbone and two organoborane complexing moieties. The two moieties are different from each other and are selected from the group of an amine moiety, a thiol moiety, and a phosphine moiety. In addition, the two moieties are separated from each other by two to four carbon atoms to increase the nucleophilicity of the blocking agent towards the organoborane initiator. The organoborane initiator is decomplexed from the blocking agent thereby forming a radical that is used to polymerize the radical polymerizable compound and cure the coating composition on the automobile component.

A method of dissociating an organoborane-amine complex in a coating composition is provided. The method includes the step of introducing the organoborane-amine complex, the radical polymerizable compound, and optionally an amine, onto a substrate to form the coating composition. The method also includes the step of introducing carbon dioxide into the coating composition in a molar ratio of at least 1:1 of the carbon dioxide to free amine groups present in the coating composition. More specifically, a carbamic zwitterion is formed in-situ from reaction of the carbon dioxide and the free amine groups. The formation of the carbamic zwitterion leads to dissociation of the organoborane-amine complex and formation of a radical. The radical is then used to polymerize the radical polymerizable compound.
