The invention includes a solid rinse aid that is particularly designed for extrusion solid formation and which is effective for creating spotless surfaces after rinsing. According to the invention, application has identified the critical combination of solid surfactants, coupling agents, hydrotrope, and hardening agents that is acceptable in the extrusion process to create a solid. The hydrotrope includes one or more short-chain alkylbenzene and/or alkyl naphthalene sulfonates. The composition hardens quickly but not so quick as to negatively impact the extrusion process. The compositions may also be used to form pressed or cast solids.

Solid rinse aid compositions, methods of use, and methods of making said composition are disclosed. Rinse aid is provided by a solidification agent, a sheeting agent, a defoamer component, and a polyacrylic acid homopolymer or alkali metal salt thereof forming a solid compositions. Preferred solidification agents include aromatic sulfonates. 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 cleaning agent which contains, separately from one another in a packaging form, at least one enzyme-containing preparation and at least one builder-containing preparation, as well as a clear rinser preparation.

A detergent composition, a method of making the detergent composition, and a method of use thereof are provided. The detergent composition comprises at least 0.001% by weight of an antimicrobial agent, based on the total weight of the composition; an enzyme; and at least 0.01% by weight of a hydrotrope, based on the total weight of the composition.

The invention provides to a powdered composition of additives and a method of use thereof for increasing the visibility, potency and coverage of disinfectant solutions, such as bleach.

A composition for a neutral floor cleaner with optimal cleaning efficacy and leaving limited to no residue and/or streaking on surfaces applied thereto is disclosed. The composition may include water, at least two cleaning agents, at least one builder, at least one stabilizer, and at least one chelator. Further, one of the cleaning agents may be water-soluble and another of the cleaning agents is water-insoluble. The amount of the two cleaning agents may also have a hydrophilic-lipophilic balance ranging from about 10.5 to about 12.5.

The application relates to a process for the synthesis of organic sulfonic acid salts of amino acid esters comprising the steps of (i) reacting at least one lactam with at least 3 carbon atoms in the lactam ring with at least one organic sulfonic acid in an aqueous solution, (ii) esterification of the organic sulfonic amino acid salt of step (i) with at least one alcohol with at least 8 carbon atoms comprising at least one hydroxyl group, (iii) optionally removal of water and/or removal of excess alcohol of step (ii). The application also relates to organic sulfonic acid salts of amino acid esters of the general formula (I).

A method for cleaning membrane is provided. The method includes, providing a membrane, introducing a thermo-sensitive ionic liquid to contact the membrane and perform a cleaning procedure to collect a cleaning solution, and layering the cleaning solution to form an aqueous layer and an ionic liquid layer at a specific temperature.

A method of treating a sensor array including a plurality of sensors and an isolation structure, where a sensor of the plurality of sensors has a sensor pad exposed at a surface of the sensor array and the isolation structure is disposed between the sensor pad and sensor pads of other sensors of the plurality of sensors, comprises exposing the sensor pad and the isolation structure to a non-aqueous organo-silicon solution including an organo-silicon compound and a first non-aqueous carrier; applying an acid solution including an organic acid and a second non-aqueous carrier to the sensor pad; and rinsing the acid solution from the sensor pad and the isolation structure.

According to the invention, the compositions and methods provide for the complete removal of labels, synthetic glues and/or adhesives from a plurality of surfaces through the use of an aqueous or non-aqueous basic organic solvent and/or an amidine, optionally in combination with surfactants, chelants, acidulants and/or additional bottle wash additives. Beneficially, the compositions and methods are suitable for use at lower temperatures and pH conditions, along with under caustic-free and/or reduced caustic conditions to effectively remove such labels, synthetic glues and/or adhesives from a surface within less than about 30 minutes.
