Use of amino carboxylate for enhancing metal protection in alkaline detergents
The invention includes ware detergent compositions which prevent buildup of precipitates and also surprisingly provides significant metal protection of items exposed to alkaline detergent composition. According to the invention alkaline ware detergents may include an effective amount of amino carboxylate. Surprisingly, detergents which included amino carboxylate also provided significant metal protection against corrosion, even when traditional corrosion inhibiting components are reduced.
Detergent compositions containing a stabilized enzyme by phosphonates
Detergent compositions that contain an enzyme, alkaline source, and phosphonate or amine phosphonate salt are described here. A use solution of the detergent compositions containing disclosed phosphonates can retain its enzyme activity for an extended period of time. Specifically, one specific type of phosphonates and another specific type of amine phosphonate salts were discovered to stabilize enzymes in detergent compositions. Solid detergent compositions that contain disclosed phosphonate or amine phosphonate salts are more effective to remove soils and can save production and use costs.
Polyesters, detergents, and cleaning agents comprising these and their use
Disclosed are polyesters containing structural units corresponding to formula (I) or to formula (II) or to formulae (I) and (II), structural units of formula (III) or of formula (IV) or of formulae (III) and (IV), and optionally structural units of the formula (V)
COR.sup.1COOC.sub.2H.sub.4O(I),
COR.sup.1COO(C.sub.3H.sub.6O)(II),
COR.sup.2COOC.sub.2H.sub.4O(III),
COR.sup.2COO(C.sub.3H.sub.6O)(IV),
COR.sup.3COOR.sup.4O(V),
as well as nonionic endgroups of the formula (VI), and optionally nonionic endgroups of the formula (VII)
CO(OC.sub.2H.sub.4).sub.nOR.sup.5(VI),
COOR.sup.6(VII).
In these structural units and endgroups R.sup.1 to R.sup.6 are selected organic radicals and n is a number between 30 and 500.
The polyesters according to the invention are characterized by very good soil release properties, can be readily stored in detergent and cleaning agent formulations and can be used as soil-release polymers.
Process for manufacturing MGDA/GLDA granules, granules, and their use
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.
Pyrithione preservative system in solid rinse aid products
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.
Alkaline detergent composition containing a carboxylic acid terpolymer for hard water scale control
A highly alkaline detergent is described which includes the use of a carboxylic acid terpolymer in combination with an alkali metal hydroxide. The detergent maintains cleaning functions and also prevents hard water scaling at application temperatures, for example at temperatures of between about 145-180 degrees Fahrenheit and, for example, at a pH of 9.5 to about 13.
PYRITHIONE PRESERVATIVE SYSTEM IN FLOOR CLEANING PRODUCTS
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.
CLEANING COMPOSITONS, KITS, AND METHODS INCLUDING GLUCAMINE DERIVATIVES
Disclosed herein are cleaning compositions effective for cleaning an oral appliance or device. The cleaning composition can include: (i) a compound of Formula (I): wherein R.sup.1 is a hydrogen atom or an alkyl group, R.sup.2 is C(O)R.sup.3, R.sup.3 is a C.sub.7-C.sub.9 alkyl group, and n is an integer from 2 to 5; and (ii) a second component selected from the group consisting of persulfate (e.g., peroxymonosulfate and peroxydisulfate) salts, percarbonate salts, perborate salts, hypochlorite salts, dichloroisocyanurate salts, trichloroisocyanurate salts, tetraacetylethylenediamine, perphosphate salts, and combinations thereof. Optionally, the cleaning composition can further include water.

TABLET PRODUCTION
The invention relates to stable, anhydrous concentrated formulations in tablet form and methods of making stable, anhydrous concentrated formulation tablets.
Solid oven cleaning composition and methods for the preparation and use thereof
A solid oven cleaning composition is disclosed herein, as well as processes for preparation of the composition and methods for use of the same. A benefit to the solid oven cleaning composition can be providing a solid composition that is compact in size yet effective and efficient to use for cleaning the surfaces of an oven. Benefits to the solid oven cleaning composition can be enabling the use of less cleaning product and less time for cleaning an oven. A benefit to the solid oven cleaning composition can be the requirement of less space for shipment and storage.
