Solid rinse aid compositions and methods of making and using the same are disclosed. Solid rinse aid compositions include in a single concentrate composition a pyrithione preservative system to replace conventional preservatives in the isothiazolinone family, such as chloromethylisothiazolinone. Beneficially, the pyrithione preservative systems eliminate the need for any personal protective equipment to handle the solid rinse aid compositions. Methods of making and use using the rinse aids are also disclosed.

In one aspect, a personal care cleaning composition in tablet form may include a surfactant and a starch composition formed from starch, alcohol and water. The tablet may be formed using a method that includes preparing the starch slurry composition comprising the starch, alcohol and water, preparing a mixture of the starch slurry composition and the surfactant, and pressing the mixture into tablet form. In another aspect, a personal care cleaning composition in tablet form may include a surfactant, a starch composition formed from starch, alcohol and water, sodium carbonate, sodium bicarbonate, citric acid, and glycol ether. The tablet may be formed using a method that includes preparing the starch slurry composition comprising the starch, alcohol and water, preparing a mixture of the starch slurry composition and the surfactant, the sodium carbonate, the sodium bicarbonate, the citric acid and the glycol ether, and pressing the mixture into tablet form.

A detergent composition in the form of an effervescent tablet having high dissolution rate and good stability, which is suitable for producing aqueous solutions of cleaning compositions for cleaning hard surfaces and clothes. The tablet includes an alkylsulfate-type anionic surfactant, an effervescent system, a combination of at least two disintegrating agents, and urea.

A solid hard surface cleaning composition suitable for replacing liquid formulations while providing at least equivalent or enhanced cleaning performance, including at lower concentrations, is provided. The solid hard surface cleaning compositions include alkali metal carbonate alkalinity source(s), aminocarboxylic acid chelant(s), amphoteric surfactant(s), polyacrylate polymer(s) and anionic surfactant(s). The solid hard surface cleaning compositions can include additional functional ingredients, such as corrosion inhibitors. The solid hard surface cleaning compositions do not include hydroxide alkalinity and beneficially provide stable ready-to-use formulations that are safe for contact without the use of personal protective equipment (PPE) and are compatible with soft metals.

The invention relates to stable, anhydrous concentrated cleanser formulations.

An effervescent detergent tablet comprising calcium carbonate, sodium laureth sulfate, citric acid, tartaric acid, sodium bicarbonate, fragrance, Stepantex VT 90 (Methyl bis[ethyl (tallowate)]-2-hydroxyethyl ammonium methyl sulfate), polyhexamethylene biguanide (PHMB), stearic acid, silicon dioxide, enzymes mix, Long Brite (Disodium Distyrylbiphenyl Disulfonate) Magnesium Stearate, Kollidon CL, Chlorhexidine Hydrochloride and calcium carbonate and sodium disilicate mix.

A solid block detergent composition is described which can be dispensed with a water spray to form an aqueous detergent for cutting and removing grease, removing and suspending soils and rinsing easily leaving cleaned ware. The solid block detergent contains a neutralized sulfonated anionic surfactant in combination with various processing aids to optimize soil removal in a formulation that can be pressed for form a solid.

Provided are a solid preparation comprising an alkyl cellulose which provides excellent moldability and disintegrability even in a small amount of the alkyl cellulose, and a production method therefor. Specifically, provided are a solid preparation having an alkyl cellulose having a specific surface area by BET method of 0.5 to 10.0 m.sup.2/g and a dissolution start temperature of 5 to 27 C.; and a method for producing a solid preparation having the steps of: mixing a cellulose pulp and a first alkali metal hydroxide solution with stirring to obtain alkali cellulose, reacting the alkali cellulose with an alkylating agent to obtain a first reaction mixture, mixing the first reaction mixture and a second alkali metal hydroxide solution with stirring and without further addition of any alkylating agent to obtain a second reaction mixture, and pulverizing an alkyl cellulose isolated from the second reaction mixture to obtain an alkyl cellulose.

Process for manufacturing granules of salts of at least two aminopolycarboxylic acids (A), com-prising the steps of (a) providing an aqueous solution of (A1) at least one alkali metal salt of a mixture of L- and D-enantiomers of methyl glycine diacetic acid (MGDA), said mixture containing predominantly the respective L-isomer with an enantiomeric excess (ee) in the range of from 10 to 95%, (A2) at least one alkali metal salt of L- and D-enantiomers of glutamic acid diacetic acid (GLDA) or of enantiomerically pure L-GLDA, the weight ratio of (A1) and (A2) being in the range of from 1:9 to 9:1, (b) spray granulating said solution with a gas inlet temperature of at least 125 C. Additionally, the present invention relates to granules and to their use.

An effervescent detergent tablet comprising sodium laureth sulfate, citric acid, sodium bicarbonate, fragrance, Stepantex VT 90 (Methyl bis[ethyl (tallowate)]-2-hydroxyethyl ammonium methyl sulfate), polyhexamethylene biguanide (PHMB), silicon dioxide, enzymes mix, Long Brite (Disodium Distyrylbiphenyl Disulfonate), Stearic Acid, Nabion 15 (Carbon-Disilicate co-granulate) and Polyethylene glycol 4000
