Liquid composition for the cleaning of hard surfaces.
the present invention relates to a composition for cleaning hard surfaces * it relates more particulièreaent a hard surface cleaning composition in concentrated liquid form " usable as such or in a diluted form incorporating water supplement. Advantageously the composition is a solution limrpide " stable phase. There are traditionally three product categories of hard surface cleaning " i.e. T- - powders th scrubbing " - creams with fine abrasive " - * the liquids The composition according to the invention belongs th this third category * it comprises phosphoric esters. Many liquid compositions for cleaning hard surfaces have been described * - déjè for most compositions have a relatively low level of active components (on average 15 - 20% by weight of active components on the weight of the composition) and have a high proportion of water * The documents OF 2,603 307 and FR 2,396 797 describes cleaning compositions comprising T-phosphate esters it is emphasized that these compositions must be acids that they provide for drying a good surface gloss on the cleaned articles * In the documents FR's 2,027 559 and FR 2,394 602 are described phosphoric esters " presented as useful for the solubilization or dispersion and hydrocarbon insoluble in aqueous medium * The document FR's Dahs 2,193 871 is described a single phase liquid detergent containing inter alia phosphoric esters "however it is taught therein that the detergent composition should comprise a major proportion of water and that the phosphoric esters James function to promote fabric softening" being specified that the detergent compositions containing them are primarily intended clothes washing with softening * Detergent compositions with phosphoric esters for the phosphoric esters are only adjuvants or enhancers' VBE1 detergency in these compositions; presented as such one other possible compounds, it is not preferred for them. In addition, the detergent compositions do not comprise surfactants' non-. ionic, but include amine oxides basic elements. On the other hand the document of 2,008 777 describes a composition of surfactants for obtaining controlled foam properties, which is a criterion by determining for the purpose machine. In this composition, phosphate esters are associated with agents nonionic surface assembly for providing a function of inhibiting foam, and these components are combined with. an anionic surfactant foaming, so that the overall composition obtained is a foaming composition to foam height regulated. The anionic surfactant necessarily comprises a sulfate or sulfonate. This document teaches that the functions: searched are better satisfied that the aütant of phosphoric esters, which are more specifically of alkyl ether phosphate, - have a low number (it is to say less than 2 based on the examples) of groups of o.vydeaikylène and a chain lengths of the alkyl group esterifying the largest possible (it is to say at least in accordance with the examples illustrating these requirements). Considerations of the same type, applied to a powder composition for washing low foaming, are developed in the document FR's 2,318 921. Despite these proposals, at remaining somewhat. contradictory, there is thus a need for detergent compositions' capable nettoyerdes hard surfaces and to remove all kinds of dirt and particulate soils, scratch-free and being in liquid form and preferably in a single phase. It was found unexpectedly that this is achieved -,, as well as other apparent to those reading the description below, using a composition combining phosphoric esters and cofiring mbinaison appropriate other components with detergent action or reinforcing - detergency, as active material, in an aqueous medium. The invention thus concerns an alkaline liquid composition, which is stable single phase, for the cleaning of hard surfaces, characterized in that it comprises: a) at least two anionic surfactants, and among them at least one soap and at least one phosphoric ester, b) at least one nonionic surfactant, c) at least one detergent builder, d) at least one sequestering agent, e); optionally fragrances and/or other additives sympathized wheats, and f) water for the balance.

The composition of the invention can also include, if desired, other non-essential consituants, such as perfumes and/or dyes and/or other compatible additives, for improving the properties or the aesthetic appeal compositions.. The composition may be formulated for cleaning hard surfaces according to the invention by preparing separately, if necessary, each of its components and then mixing them intimately, water which is taken in conjunction with the solvent medium. This preparation can be done using techniques known to the skilled person. In its embodiment concentrated, in particular with a content of active material of 30 to 60% approximately, the composition advantageously contains as component (e) deionized water of the demineralized water. Alternatively the concentrated composition as aforesaid may be diluted, either when it is produced, either before use, and stored under this diluted form. In this case the water supplement may be, bag for all or part, tap water. The composition obtained both in its variant as concentrated as in its variant diluted, and particularly one that includes the preferred components, set forth above and of which the respective proportions of the components are those indicated above with reference to the concentrated formula, is storage stable, advantageously in a clear single phase. It has been found unexpectedly that the composition in concentrated form according The diluted composition obtained is also part of the present invention present tee. It constitutes a product corresponding to the domestic habits and to actively cleaning material ratio accords with the cleaning to be performed, particularly for cleanings, both occasional as routine, of hard floors, tiles, painted surfaces leachable, worktops, plumbing fixture, andc. The advantage critical concentrated formulation on the diluted formulation is that, while allowing the end user to easily obtain therefrom and to store it for subsequent usages, it makes possible a net reduction in costs and constraints for demineralizing town water for industrial manufacturer and greatly reduces the personal identification data set and the volume of the package, as well as the costs of storage and transportation, for an equivalent content of active material. Use in under normal conditions and as domestic habits. current, the compositions according to the invention ensure that all dirt, even very tough, hard surfaces both slightly porous that non-porous, and dries without traces. Sub compositions according to the invention, the soap provides an essential contribution detergency on hard surfaces and, in combination with phosphoric esters and nonionic surface agents, it ensures the stability of the composition in a single phase liquid and clear. The invention is illustrated in more detail in the examples hereinafter, which does limit the scope. In these examples also, agree with the percentages by weight of the component to 100% pure, based on the total weight of the composition. Abbreviations employed, pâr example 5 EO, are conventional and define one hand lê carbon number of alkyl groups and the levels of ethylene oxide groups of the affected molecules. Example 1.
