The need for a liquid hand dishwashing cleaning composition that is less hazy, while also provides reduced surface tension between the detergent composition and the soiled plate, and hence improvements in cleaning, is met when the liquid hand dishwashing cleaning composition is formulated with a surfactant system and a polyvinyl alcohol having a degree of hydrolysis of from about 40% to about 86%.

The invention is a detergent solution for cleaning a receptacle for milk or liquid milk-derived products, the detergent solution comprising water, one or more types of surfactant and an odour absorbing compound. The surfactants are provided to dissolve greasy milk-based residues from the receptacle and the odour absorbing compound is provided to neutralise odours produced by any remaining milk-based residues not removed by the surfactants. The detergent solution is water-based so that it can be rinsed off easily in a sink in the home. The detergent solution is particularly suited to plastic receptacles because plastic is more prone to accumulating mal-odour producing bacteria. This is because a plastic surface is more porous than glass so it is more difficult to remove greasy residues from a plastic surface and therefore grease can build up in the pores, out of the reach of surfactants, and provide a place for odour-producing bacteria to grow. An odour absorbing compound does not remove the residue but can neutralise the odours from the residue. The invention also discloses a method for dispensing a detergent solution comprising at least one surfactant, the method comprising ejecting detergent solution from a reservoir in the form of a spray, wherein the surfactant is present in the detergent solution in an amount of from 3% to 15% by weight of the detergent solution. The invention discloses also a method of cleaning a receptacle for milk, or liquid milk-derived products, the method comprising: spraying a detergent solution comprising at least one surfactant onto the receptacle, wherein the surfactant is present in the detergent solution in an amount of from 3% to 15% by weight of the detergent solution.

A liquid bioactive composition is provided that includes an enzyme with enzymatic activity toward a component of a biological stain. Also provided is a process for facilitating the removal of a biological stain is provided wherein the enzyme in the liquid bioactive coating material is capable of enzymatically degrading of one or more components of the biological stain to facilitate biological stain removal from a substrate.

The present invention relates to a method for removing a foreign material from the surface of an article comprising the following steps: i) providing an article having a surface covered at least partly with a foreign material; ii) contacting the article provided in step i) with a cleaning medium being an acid having a pKa in the range from −10 to 7 having a minimum concentration of 1 wt.-% and with a carrier medium having a density different from the density of the cleaning medium to obtain a mixture comprising the foreign material solved and/or dispersed in the cleaning medium, the carrier medium and the article free from the foreign material; iii) allowing the mixture obtained in step ii) to separate to obtain a heterophasic emulsion comprising at least a first phase comprising the carrier medium and the article free from the foreign material and a second phase comprising the cleaning medium and the foreign material solved and/or dispersed therein; iv) separating the phases obtained in step iii); and v) separating the article free from the foreign material from the carrier medium. Furthermore, the present invention relates to an installation for carrying out the inventive process.

A method of forming a gel or gel-like detergent composition comprising: dosing a solid composition, and dosing a liquid composition; into a water-soluble container.

The application relates to a shaped detergent product comprising 10-100 wt. % of a solid amorphous phase and 0-90 wt. % of one or more other solid phases, wherein the solid amorphous phase comprises 25-88 wt. % free acid equivalent of aminopolycarboxylate, 10-60 wt. % free acid equivalent of an acid, wherein the acid is not an aminopolycarboxylate, 2-30 wt. % water, and wherein the shaped detergent product contains at least 0.5 wt. % surfactant.

The need for a liquid hand-dishwashing composition which provides further improved sudsing volume and longevity when washing dishware using diluted liquid hand dishwashing compositions, especially in the presence of greasy soil and particulate soil, while still providing the desired cleaning, is met when the composition is formulated with from 5% to 50% of a sudsing surfactant system and polyvinyl alcohol having a viscosity of from 20 mPa.Math.s to 55 mPa.Math.s.

The present invention relates to a recycling process for a laminate and a solution used in such a process. The present invention finds particular application in the removal of an adhered overlay from an underlying substrate material such as plastic. The process includes subjecting the laminate to an impact frictional striking force, thereby substantially separating the substrate layer from the one or more surface layers of the overlay and then washing the substrate layer with a washing solution to remove the remaining surface layers of the overlay and glue from the substrate layer. The washing solution may be an aqueous solution including a surfactant, a solvent and a base.

Bioactive coatings that include a base and a protein associated with the base for actively promoting the removal of organic stains are provided. In aspects, bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.

A method of washing glassware is provided including: providing automatic dishwashing apparatus; providing soiled glassware; placing soiled glassware in automatic dishwashing apparatus; providing wash water; providing rinse water; selecting anhydrous mixed powder or mixed granule comprising: 2.5-5 wt % of oxidized maltodextrin, wherein oxidized maltodextrin has Degree of Oxidation of 0.4-1.7; 10-25 wt % of amino acid based builder; 20-75 wt % of additional builder, wherein additional builder includes at least one of sodium citrate, sodium carbonate and sodium percarbonate; 2.5-7.5 wt % of bleach activator; 0.5-10 wt % of nonionic surfactant; 0.5-1 wt % of phosphonate; 1-6 wt % of enzyme; 5-15 wt % of filler; and <1 wt % water; placing selected anhydrous mixed powder or mixed granule in automatic dishwashing apparatus; contacting selected anhydrous mixed powder or mixed granule with wash water to form combination; contacting soiled glassware with combination to provide treated glassware; and then contacting treated glassware with rinse water to provide cleaned glassware.
