Concentrated water-soluble powdered detergent

Description

Technical Field

[0001] The present invention relates to a water-soluble powder detergent, a liquid detergent composition comprising it and the use thereof for pre-washing and / or internal and / or external washing of vehicles or parts thereof or for washing industrial floors and / or surfaces.Background of the invention

[0002] In the detergent sector, in particular in the sector of detergents for car washes or for industry in general, the use of water-based liquid detergents, generally produced and packaged in plastic packagings of 10, 25, 100, 200 or 1000 kg has been known for some time. Such a type of packages, necessary for the safe transport of liquids, involves the use of a relatively high quantity of plastic which accounts for about 5% by weight of the total product. Since this type of detergents is generally made in the production plant and only subsequently delivered to the end user by transporting (generally by road) the aforesaid packages, it is clear that not only the high quantity of plastic but also fuel cost and consumption for the transport of the aforesaid liquids (relatively heavy) are disadvantageous both from an economic point of view (costs of management and maintenance of the means of transport) and from an environmental point of view.

[0003] WO 2010 / 076595 A1 discloses liquid cleaner concentrate compositions in the form of an aqueous thickened emulsion comprising about 15 to about 50 wt % of a source of alkalinity; about 2 to about 30 wt % of a nonionic surfactant; about 0.1 to about wt % of a water conditioning or sequestering agent, such as hydroxyethlidene diphosphonic acid, and an optional alkyl polyglucoside surfactant. CA 2 685 979 A1 discloses solidification matrices in detergents for washing vehicles and cleaning floors. US 2010 / 093597 A1 discloses a concentrate composition, comprising: (a) an amine oxide surfactant, (b) an alkali metal hydroxide, (c) a secondary source of alkalinity, (d) a surfactant, and (e) a chelating agent, wherein the composition is formed into a solid useful in preparing a stable, aqueous use solution.

[0004] The need therefore remains in the sector to reduce the volumes of plastic packaging used and at the same time reduce the costs for the transport of large quantities of liquid detergent while reducing the total environmental impact.

[0005] The present invention solves the disadvantages listed above by providing a water-soluble powder detergent, which allows to directly make in situ and when needed, liquid detergent solutions having an optimal detergent power.

[0006] Furthermore, the present invention, by mixing the aforesaid powder with a polar solvent, preferably aqueous, in the appropriate quantities, allows to make detergent solutions with the desired concentrations, which can be modulated according to the specific application (i.e. pre-washing of vehicles, washing of industrial floors and / or surfaces or vehicles, interior upholstery cleaning, rim cleaning, etc.). Compared to having to purchase a different liquid detergent for each specific use, the present invention provides an advantageous system in that it can be implemented each time during the actual application and can be customised. The present invention therefore allows to reduce the volumes of detergent to be transported to the final user, thus considerably reducing the environmental impact and the costs for transport and logistics.Summary of the invention

Without wishing to bind to a specific theory, the Applicant has observed that, thanks to the combination of the specific powder compounds described above, it is possible to obtain a water-soluble powder detergent which is formed easily and rapidly, once mixed with a polar solvent (preferably with an aqueous solvent, more preferably with water), homogeneous and stable solutions over time (i.e. without the formation of non-dissolved substances). The solutions, preferably the aqueous solutions, thus formed (called for the purposes of the present invention as "liquid detergent compositions") are effective detergents that ensure an adequate removal of multiple types of dirt (organic and synthetic) even at low concentrations, at low temperatures (i.e. even at temperatures slightly above 0°C) and in the presence of particularly hard waters.

[0052] The present invention also has the advantage connected to the fact that such a powder detergent can be easily transported and, once it reaches the place of destination and at the time of actual need, be dissolved in a polar solvent (preferably in an aqueous solvent, more preferably in water) at the desired concentrations for the purposes of the specific intended use according to the present invention, to form the optimal detergent liquid composition without wasting products and excessive transport and / or packaging costs.

[0053] Alternatively, as already mentioned above, it is possible to dilute a more concentrated liquid detergent composition up to the optimal concentrations for use according to the present invention, also in this case saving in terms of packaging and transport costs / safety.

[0054] Among the advantages of the present invention it is therefore possible to include a saving in transport up to 80%, an optimisation of production costs, a packaging disposal reduced to a minimum as well as the possibility of obtaining on demand detergents customisable for different uses by easily and quickly modifying the dilution in polar solvent (preferably in an aqueous solvent, more preferably in water) or the concentration of the powder dissolved therein.Examples Example 1 - odourless water-soluble powder detergent
