The invention relates to a cleaning product comprising: an inverted container assembly (10) comprising an inverted container (11) and a liquid dispenser (15) attached to a bottom surface (12) of the inverted container (11), and a viscous cleaning composition contained in the inverted container assembly (10).

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%.

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.

Dry mixtures and liquid formulations are provided that comprise metal oxide and/or metal hydroxide nanocrystalline particles. The dry mixtures are advantageously formulated with select surfactants to be readily solubilized and stable in liquid carriers. Additional select components are provided in preferred combinations that are capable of achieving improved biocidal and chemical agent efficacy. Notably, the inventive formulations provided herein allow for easier delivery of the formulations and increased shelf stability.

Surfactant compositions comprising an alkoxylate, a sulfate, or ether sulfate of a C.sub.10-C.sub.12 monounsaturated alcohol are disclosed. The alkoxylate, sulfate, or ether sulfate may derive from undecylenic acid or undecylenic alcohol. Compared with their saturated analogs, the monounsaturated alkoxylates, sulfates, and ether sulfates are less irritating, making them valuable for personal care, laundry, cleaners, and other household applications. Microscopy studies show that the alkoxylates, sulfates, and ether sulfates have favorable phase behavior over a wide range of actives levels, expanding opportunities for products with greater compaction. When combined with cationic surfactants, the alkoxylates, sulfates, and ether sulfates exhibit synergy, and they have improved solubility compared with their saturated analogs. The surfactants find value for the personal care, laundry and cleaning, emulsion polymerization, agricultural products, oilfield applications, and specialty foams industries.

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 two component composition and a method for depositing a water-soluble film on a surface. The present two component composition comprises a first component comprising at least one, two, three or more or all first surfactants and water and a second component comprising at least one, two, three or more or all second surfactants and water, wherein contacting the first component a) and the second component b) causes forming of the water-soluble film. Also the present invention relates to a water-soluble film preferably a cleaning gel obtained or obtainable by a method according to the invention.

A fluid washing composition with four separate components and laundry washing kit thereof is disclosed. The four components are housed in respective independent tanks of a laundry washing machine equipped with a program for selecting, dosing and differentiated delivering. Component 1 is a detergent formulation with a pH of 4.0-12.0, with high detergent effect in washing programs at temperatures of 40°-60° C., having a specific action on cotton fibers, particularly, whites. Component 2 is a detergent formulation with a pH of 8.0-12.0, with high detergent effect in washing programs at temperatures of 15°-40° C., having a specific action on synthetic, colored and animal-origin fibers. Component 3 is an enzyme-based stain-removing formulation including protease and lipase and possibly amylase with a pH of 5.0-6.0, stabilized with sorbitol and calcium chloride. Component 4 is an after-wash conditioning formulation, with a pH of 2.0-4.0.
