A method for producing a washing agent portion unit having at least one receiving chamber surrounded by a water-soluble film, including the steps of: a) transporting a first water-soluble film in the direction of a dosing station; b) molding the first water-soluble film into the cavities of a deep-drawing die located below the water-soluble film, forming at least one cavity in the direction of travel of the film; c) filling the cavity by way of the dosing station with a first flowable washing agent preparation containing, based on its total weight, i) 20 to 80 wt. % surfactant; ii) 2 to 15 wt. % fatty acid; iii) 0.3 to 8 wt. % of the salt of a divalent cation; iv) 8 to 35 wt. % solvent; d) transporting the filled cavity in the direction of a sealing station; e) sealing the filled cavity with a second water-soluble film, and the washing agent portion.

The invention relates to compositions and methods that are useful in etching a metal surface. In particular, the invention relates to novel acid compositions and methods of using such compositions in etching a metal surface, preferably an aluminum surface prior to anodizing to dissolve impurities, imperfections, scale, and oxide. The compositions are effective in maintaining their etching capacity and in removing smut produced by the etching of a surface as well as in general cleaning.

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.

The present invention relates to personal care compositions comprising malodor reduction compositions and methods of making and using such personal care compositions. Such personal care compositions comprising the malodor control technologies disclosed herein provide malodor control without leaving an undesireable scent and when perfume is used to scent such compositions, such scent is not unduely altered by the malodor control technology.

A laundry detergent formulation is provided that is formed as an aqueous blend of surfactants, enzymes, builders, and soil release polymers to inhibit soil re-deposition back onto other clothing or elements of the washing machine. The detergent formulation also contains additives with properties that impart a treatment to fabrics that inhibits future soil deposition onto the clothing with continued use. The detergent formulation provides cleaning of heavy duty grease and automotive soils from clothing surfaces that is superior to current detergent products.

The present disclosure relates to detergent compositions that comprise renewable components and exhibit good performance, as compared to both traditional detergent formulations that contain non-renewable ingredients and known detergent formulations that contain renewable components.

A composition for cleaning hard surfaces includes from 3 to 20 wt-% dicarboxylic acid; from 3 to 25 wt-% surfactant; from 0 to 20 wt-% solvent; and water, and has a pH from 9 to 12.5. A ready-to-use solution of the composition includes from 0.1 to 5 wt-% dicarboxylic acid; from 0.1 to 5 wt-% surfactant; from 0 to 5 wt-% solvent; and water, and has a pH from 9 to 12.5. The composition is safe for use with calcite stone surfaces. A method of cleaning calcite stone surfaces comprises a use solution of the composition to the calcite stone surface, and rinsing, wiping, or scrubbing the surface. Another method of cleaning calcite stone surfaces comprises preparing a use solution by diluting the composition with water, applying the use solution to the calcite stone surface, and rinsing, wiping, or scrubbing the surface.

The present invention is directed to visually contrasting aesthetic particles having increased water solubility, particularly useful for combination with granular laundry detergent composition.

Acidic viscoelastic cleaning compositions are disclosed which use non polymer thickening agents. According to the invention, cleaning compositions have been developed using viscoelastic surfactants in acidic cleaning formulations. These provide the dual benefit of thickening as well as an additional cleaning, thereby improving performance. Applicants have also identified several pseudo linking agents which when, used with viscoelastic surfactants provide enhanced viscoelasticity and cleaning.

A process for making a particle, the particle includes: a) a nitrogen-containing cleaning-active in the form of a salt wherein the salt has a pH in 1% weight aqueous solution measured at 25° C. greater than 9; and b) a malodour-reducing agent including an acid group wherein the process includes the step of adding the malodour-reducing agent to the nitrogen-containing cleaning-active wherein the malodour-reducing agent is added in the absence of water.
