Definitions
- the present invention relates to new concentrated and dilutable solutions or dispersions, their preparation process and their applications.
- a conventional micro-emulsion of terpenic solvent has the following typical composition: water / polyoxethylenated fatty alcohols / polyoxethylenated nonylphenols / sodium xylene sulfonate / isopropanol / terpenic solvent. Its lifespan is limited, as is its resistance to temperature. It can therefore only be used cold. Conventionally, microemulsions are obtained by gradually adding, with stirring, an aqueous phase to an organic phase (or vice versa), in the presence of a surfactant, and if necessary a third solvent.
- Microemulsions are homogeneous compositions, but they contain significant concentrations of formulating agents, in particular emulsifiers and hydrotropic agents.
- WO-A-91/00893 describes paint and varnish removers possibly containing water and being in the form of gels or supports impregnated on organic clays such as bentones. These compositions involve at least 10% of a third water-soluble solvent of N-methyl pyrrolidone type.
- the present application relates to a composition in the form of a liquid / liquid dispersion of the microemulsion type or solution of an active agent, concentrated and dilutable with water, characterized in that it is clear as water and that it essentially comprises at least 10% by weight of a hydrophobic active agent having a KB index (Kauri butanol) greater than or equal to 30 and preferably 40 or less than 10% of an N -alkyl pyrrolidone and - a glycol ether or preferably a mixture of two glycol ethers, in the latter case the first glycol ether having an HLB greater than 0.8, preferably 0.9 and very particularly 1.0 to that of the second glycol ether.
- a hydrophobic active agent having a KB index (Kauri butanol) greater than or equal to 30 and preferably 40 or less than 10% of an N -alkyl pyrrolidone and - a glycol ether or preferably a mixture of two glycol ethers, in
- the term “essentially” means at least 90% by weight of the composition, preferably at least 95% and very particularly at least 98%.
- hydrophobic is meant that the active agent has a low solubility in water.
- the solubility in water of the active ingredient (s) will preferably be less than or equal to 8%, in particular less than or equal to 6%, particularly less than or equal to 4%, very particularly less than or equal to 1%.
- composition When the composition is a microemulsion, it is for example water in oil (W / O), in particular “multiple” (O / W / O or W / O / W), and particularly oil in water (O / W) .
- glycol ether When only one glycol ether is used, it will have a high HLB. Particular use is made of the methyl ether of dipropylene glycol. When two glycol ethers are used, the methyl ether of dipropylene glycol is used in particular as the first glycol ether.
- the glycol ethers may represent, for example, 50% to 90% by weight of the concentrated microemulsion, in particular 60% to 90%, and very particularly 70% to 90%.
- the ratio of the first glycol ether to the second glycol ether may range, for example, from 1: 8 to 4: 5, in particular from 1: 5 to 3: 5, and very particularly from 1 : 3 to 2: 5 by weight.
- the active agent having a KB index preferably greater than or equal to 30 and in particular to 40 will be chosen from fatty substances, terpene derivatives of synthetic, semi-synthetic or natural origin, rectified or not (by distillation) such as essential oils of pine, citrus terpenes, especially orange such as d-limonene, solvents non-water-soluble organic substances of petroleum origin aliphatic, including isoparaffinics, certain carboxylated derivatives, such as esters such as dimethylesters, certain amides, carbonylated derivatives such as certain ketones, certain aldehydes, polar solvents other such as terpene alcohols, alcohols fatty (therefore high molecular weight), thiols, certain amines, and ethers comprising for example from 4 to 15 carbon atoms, preferably from 5 to 14 carbon atoms, in particular from 7 to 13 carbon atoms.
- fatty substances terpene derivatives of synthetic, semi-synthetic or natural origin,
- the active agent will preferably be chosen from citrus terpenes, in particular orange; d-limonene is particularly retained.
- the active agent will most particularly be d-limonene, a mixture of RPDE dimethylesters or their mixture.
- an active agent used in cosmetics as a moisturizer such as evening primrose oil, a soothing and healing as alianto ⁇ ne, a UV agent such as phenoxyethanol or Mexoryl ®, an anti-aging agent such as retinol, retinaldehyde, vitamin A acid, an exfoliating agent, an antioxidant agent or an active pharmaceutical agent usable in dermatology such as a corticosteroid.

- an anti-aging agent such as retinol, retinaldehyde, vitamin A acid, an exfoliating agent, an antioxidant agent or an active pharmaceutical agent usable in dermatology such as a corticosteroid.
- the N-alkyl pyrrolidone is preferably N-methyl pyrrolidone. It is obvious to those skilled in the art that in the present application when we speak of "a" given product, we must understand "at least one" product considered when the context justifies it. This is the case for example for the active agent which can be a mixture of active agents, or for the emulsifiers.
- the above microemulsions or solutions may also comprise one or more conventional additives chosen, for example, from additives soluble in a non-aqueous phase such as perfumes, and preservatives such as formaldehyde or parabens.

- the present application also relates to a process for the preparation of a microemulsion or concentrated solution above, characterized in that the active agent or liquid active agents and the glycol ethers or ethers are mixed with stirring to emulsify or dissolve them.
- this preparation can be done hot, it has the remarkable advantage of being able to be carried out at room temperature and quickly, in a few minutes of stirring, for example using a stirrer with 1 or 2 propellers, that is, the process requires a minimum of energy.
- a non-liquid active agent should be melted or dissolved beforehand to pass into liquid form.
- the present application also relates to a process for the preparation of a dilute microemulsion, characterized in that the diluent, the glycol ethers or ethers and the active agent or liquid active agents to be emulsified are stirred .
- the mixing order is not critical. In preferential conditions of implementation, a premixture of the diluent, of the glycol ethers or ethers is mixed with stirring, then the active agent or liquid active agents to be emulsified are added gradually with stirring. By adding “progressively” is meant for example adding 10% V ⁇ per minute.
- the diluent is in particular water or an aqueous phase. It is also in particular an isoparaffinic solvent. It can also be a non-water-soluble aromatic organic solvent such as petroleum solvents of the white spirits type.
- a microemulsion or dilute solution can also be prepared by diluting a microemulsion or concentrated solution above.
- the glycol ethers may represent, for example, 15% to 85% by weight of the diluted microemulsion, in particular 20% to 80%, particularly 25% to 70%, and very particularly 30% to 50%. .
- the aqueous phase preferably consists of water, in particular demineralized water.
- the aqueous phase preferably further comprises a softening agent such as a phosphonate or the tetrasodium salt of ethylene diamine tetraacetic acid.
- a softening agent such as a phosphonate or the tetrasodium salt of ethylene diamine tetraacetic acid.
- the softening agent may represent around 0.5% by weight of the composition.
- the aqueous phase can also contain, if desired, one or more water-soluble compounds such as dyes.
- compositions of the invention also exhibit high rinsability with water, in particular active agents which are not by nature, and / or a possibility of aqueous dilution and separation of phases adjustable at will and predetermined.
- microemulsions or solutions according to the invention are easily recyclable. After use, a simple aqueous dilution makes it possible to reduce the volume of non-aqueous effluents to be treated.
- the used solution or microemulsion quickly separates into two distinct phases, one of which is a non-aqueous phase. During the phase separation, the glycol ethers are distributed within each phase to facilitate the transfer and solubilization of the respective impurities and contribute to the clarity of the interface.
- the system according to the invention has total reversibility.
- the non-aqueous phase may be filtered and / or rectified for recycling.
- the simple addition of methyl ether of propylene glycol and water will recreate the initial product.
- This recycling can be repeated several times
- glycol ether (s) according to the invention, it is possible to obtain, even with the same composition of the remainder of the formula, microemulsions of active agents of chemical nature and also different polarity. than d-limonene and mixtures of dimethylesters.
- microemulsions of the invention make it possible to produce an excellent surface preparation of the mechanical parts before mounting or applying a protective coating. They can be used on most metals, alloys, plastic materials and elastomers, especially for exterior maintenance of aircraft.
- compositions which have excellent chemical harmlessness with respect to seals and sensitive materials.
- polycarbonates EPDM
- micro-emulsions or solutions of the invention as industrial solvent, cleaner - renovator or surface treatment for plastics such as garden furniture, as cleaner - renovator for stained wood. or blackened, cleaner for polyurethane foam. They also justify the use of the microemulsions or solutions of the invention for eliminating putty residues, cleaning brushes, removing glues and adhesives and diluting all paints. They still find their use in boating (washing wood, plastics, mechanical elements, ...) as long as they are rinsable with sea water unlike detergents, or even, for those involving a N-alkyl pyrrolidone, in pickling.
- microemulsions were prepared as follows:
- the methyl ether of dipropylene glycol is very gradually incorporated in demineralized water, in 5 minutes, until the mixture is clear.
- the mixture of RPDE dimethylesters or d-limonene is incorporated.
- Stirring is continued for 5 minutes and the homogeneity of the microemulsion is checked, for example by observing its transparency. It is observed that the use of 25% by weight of the methyl ether of dipropylene glycol alone makes it possible to emulsify from 2 to 10% of mixture of RPDE dimethylesters.
- the use of 80% of this ether alone makes it possible to emulsify from 2 to 10% of d-limonene. Water represents 100% by weight in both cases.
- microemulsions were prepared in the following manner: While maintaining constant stirring, very gradually incorporated into demineralized water, over 5 minutes, the methyl ether of dipropylene glycol and the n-butyl ether of propylene glycol . Always maintaining constant agitation, the mixture of RPDE dimethylesters or d-limonene is incorporated. Stirring is continued for 5 minutes and the homogeneity of the microemulsion is checked, for example by observing its transparency.
- composition containing 27% of methylpropylene glycol ether and 10% of n-butyl ether of propylene glycol makes it possible to emulsify from 2% to 20% of mixture of RPDE dimethylesters without having to make an adjustment of formula other than water qs 100% by weight. It is also observed that a stable microemulsion containing 15% of mixture of RPDE dimethylesters is obtained by using a mixture of 26% dipropylene glycol methyl ether with 5 to 15% propylene glycol n-butyl ether . Water here also represents qs 100% by weight.
- a stable micro-emulsion according to the invention of 10% d-limonene containing 5 to 20% water can be prepared using in the first case 85%% d 'methyl ether of dipropylene glycol and in the second case 45% of this glycol and 25% of n-butyl ether of propylene glycol.
- microemulsions were prepared by mixing in 5 minutes, until the mixture is clear, the methyl ether of dipropylene glycol and the n-butyl ether of propylene glycol, then, while maintaining constant stirring, the mixture of RPDE dimethylesters. The mixture is stirred again for 5 minutes and the homogeneity of the microemulsion is checked.
- Example 5 After diluting 1/1 of Example 7 with water, the diluted microemulsion of Example 5 is obtained if desired with 11.0% of propylene glycol n-butyl ether.
- microemulsion of Example 8 is dilutable in all proportions, in particular in water.
- the last line of the table represents the quantity of aqueous phase, for example of water, from which a release of the organic phase is caused, as well as the capacity of the microemulsions to absorb, for example water, that is, to be diluted.
- Example 6 For example with regard to Example 6, 100 g of the original microemulsion (representing 100% by weight) having then been used for degreasing automotive mechanical parts, when 40 ml of water are added with the micro-emulsion of soiled origin, agitates then leaves to stand, the appearance of a cloudiness is observed, witnessing the loss of the homogeneity of the composition, then there is a phase shift in two clear superposed phases with a very clear separation at the interface.
- the hydrophilic phase represents 92 ml for 65.3 ml at the start. Since 40 mL of water was added, about 80% of the starting hydrophilic phase was therefore recovered.
- the properties of the compositions of the invention therefore make it possible to have to treat only a reduced volume of liquid.
- a very large proportion of organic upper phase n-butyl ether of propylene glycol and d-limonene
- This example 14 shows that thanks to the use of glycol ether (s) according to the invention, a microemulsion of active agents of chemical nature and polarity as different as d-limonene and mixtures is obtained. of dimethylesters.
- a microemulsion corresponding to the formula of Example 18 was prepared but by replacing the mixture of RPDE dimethylesters with a mixture of 5% of said mixture of RPDE dimethylesters and 5% of d-limonene.
