Technical Field

The present invention relates to a liquid mixture (preferably an oil-in-water emulsion) for cleaning paint, varnish, dye and/or wood stain spills, the use thereof and a cleaning process comprising the step of applying said mixture to fresh stains formed by paint, varnish, wood stain and/or dye.

In the environment, humans are increasingly exposed to accidental paint, varnish, dye and/or wood stain spills. In particular, in the supermarket sector and in the paint speciality sector, accidental spillage of paint, varnish, dye and/or wood stain is very frequent.

The consequences of these spills, both economically and aesthetically, and also for the safety of the professional and public working environment are very serious.

Background

To combat accidental paint, varnish, dye and/or wood stain spills, a number of products are used.

The most commonly used products are paint solvents or diluents, such as white spirit or CR 10 diluents. These paint solvents or diluents can effectively clean stains regardless of the nature of the paint, varnish, dye and/or wood stain spilled. However, these products, which are composed primarily of hydrocarbons, are carcinogenic, flammable, toxic, and environmentally hazardous.

In an attempt to overcome these disadvantages, other alternative solvents have been marketed. Among the latter, mention may be made of the product sold by the company Onyx under the name "solvapoint" or the product sold by the company even Build under the name "Brush cleaner".

However, these products are flammable, irritating, and/or toxic and are therefore equally harmful to humans and the environment.

Furthermore, solvent-based products are generally incompatible with painted, varnished, resinated, painted and/or plasticized flooring so that they degrade after use.

Water can also be used to clean fresh paint stains. However, it is possible to use a single-layer,due to their inability to clean paint from solvent-based or oil-based paints such as the paint known as "glycerophotchalic", the so-called "oil-based" paintsThe paints (paints based on heavy petroleum naphthas and hydrocarbons as solvents) or polyurethane paints, and therefore their use in the field of application is still very limited. Indeed, the immiscibility of these solvent-based paints with water prevents any effective cleaning and results in the spreading of the stain rather than the cleaning of the stain.

Recently new products called "eco solvents" or eco solvents have been developed. Mention may in particular be made of the product "Ecosolvent" from Biotech, of the product "Ecosolvant" from Charbonneaux-brabannt or of the product "Safer spray" from Ever Build. These ecological solvents have the advantage of being biodegradable and harmless to the environment. On the other hand, they are still sufficiently aggressive to degrade painted, varnished, resinated, painted and/or plasticized floors and cannot be used for high-viscosity solvent-based paints. In addition, ecological solvents are very odorous products, the odor of which is unpleasant for many users.

Thus, there is currently no liquid mixture (preferably an oil-in-water emulsion) for cleaning paint, varnish, dye and/or wood stain spills that simultaneously:

(1) has no irritation, no toxicity, no corrosion, no carcinogenicity, no flammability and no harm to users,

(2) is biodegradable and harmless to the environment,

(3) any type of stain formed by paint, varnish, dye and/or wood stain can be cleaned,

(4) can be used for any type of flooring without degrading it, including painted, varnished, lacquered, resinated and/or plasticized flooring,

(5) does not leave stains on the floor after use, and

(6) the comfort of the user is not impaired during use, for example, unpleasant and strong smells are emitted.

In practice, these six criteria may be contradictory. However, the inventors have worked to find a liquid mixture (preferably an oil-in-water emulsion) for cleaning paint, varnish, dye and/or wood stain spills which exhibits an excellent compromise between these various criteria (1) to (6).

Detailed Description

Certain definitions of terms used in the context of the present specification are given below.

The term "liquid mixture" means a single phase mixture or a multiphase mixture, such as a suspension or emulsion of two or three phases. Preferably, the mixture according to the invention is an emulsion.

The term "emulsion" means a dispersion consisting of a mixture of at least two liquids immiscible with each other, one of which is dispersed in the other in the form of droplets (european pharmacopoeia, eighth edition, volume 1 (2014): 835).

The term "oil-in-water emulsion" means an emulsion whose dispersed phase is an aqueous phase. These emulsions contain a surfactant or mixture of surfactants having an HLB of 8 to 16 to stabilize the system.

The HLB (hydrophilic lipophilic balance) of a surfactant or mixture of Surfactants will be determined by the Griffin method (Griffin WC: Classification of Surface-Active Agents by 'HLB)' Journal of the Society of Cosmetic Chemists 1(1949):311.Griffin WC: calibration of HLB value of Non-Ionic Surfactants, Journal of the Society of Cosmetic Chemists 5(1954): 259).

The emulsion may show signs of phase separation, but is easily redispersed by shaking.

The Hansen solubility parameter is a physicochemical property of all types of chemical products and their miscibility with other substances can be assessed. Hansen in its paper by Charles M.Hansen (Hansen, Charles: The three dimensional solution Parameter and Solvent Difsion Coating and The IR imaging in Surface Coating formulation. copenhagen: Danish Technical Press (1967)).

Various chemical solvents can be classified according to Hansen solubility parameters, which are each indicative of:

energy of intermolecular dispersion force: delta D

Energy of dipole force between molecules: δ P and

energy associated with intermolecular hydrogen bonding: δ H.

Furthermore, all of the aforementioned products are not harmful to humans and the environment.

In a preferred embodiment, the mixture as defined above is an emulsion.

In a preferred embodiment, the emulsion is an oil-in-water emulsion, wherein the dispersed phase is water and the dispersed phase is an organic solvent.

In a preferred embodiment, the mixture as defined above does not comprise sulfosuccinate salts.

It is therefore an advantage of the present invention to provide a liquid mixture (preferably an emulsion) that makes it possible to clean any stains resulting from paints, varnishes, dyes and/or wood stains, irrespective of the type of paint, varnish, dye and/or wood stain just spilled and irrespective of the condition of the floor or surface on which the accident occurred, in a manner that is not harmful to both its user and the environment.

The term "clean" means the action of removing paint, varnish, dye and/or wood stain spills that have not yet dried completely on contact with air by mixing them with the mixture according to the invention (preferably an emulsion) in order to obtain a floor that is as clean and attractive as the initial floor before spillage.

In fact, the composition according to the invention makes it possible to dilute and strip from the surface any type of paint, varnish, dye and/or wood stain that has not yet dried completely on contact with air.

Examples of paint types include, but are not limited to, solvent-based paints, water-based paints, acrylic paints, polyurethane paints, polyepoxy paints, and glycerophthalic acid paints.

In other words, the mixture (preferably an emulsion) can be used to clean up spills of fresh paint on the paint support without adversely altering the paint support.

The mixture (preferably emulsion) according to the invention is not harmful to its user and not to the environment. Thus, the mixture (preferably emulsion) according to the invention complies with REACH european regulation (EC) No. 1907/2006, 12/18/2006, in terms of the nature and concentration of the components of the mixture (preferably emulsion), and does not require the labels (classification, labeling and packaging, regulation (EC)1272/2008, 12/16/2008) relating to the european CLP regulation.

The mixture according to the invention, preferably an emulsion, is non-irritating, non-toxic, non-corrosive, non-carcinogenic and non-flammable and can be used without risk. The mixtures (preferably emulsions) according to the invention are not harmful to the environment and are biodegradable.

It may be desirable to use an antibacterial Agent (ATB) in combination with an antifungal Agent (ATF).

Thus, the addition of at least one preservative makes it possible to obtain a mixture (preferably an emulsion) that does not allow the growth and propagation of bacteria, fungi and/or moulds.

Preservatives are those conventionally used, in particular of the alcohol, acid salt, acid ester or essential oil type.
