Definitions
- the present invention relates to the degreasing of the surface of a metal, ceramic, glass, or made of plastic.
- chlorinated solvents in particular 1,1,1 trichloroethane. These are harmful products to the environment, especially the ozone layer stratospheric. It is planned to prohibit its use in the years to come. We also know processes aqueous less effective despite their complex formulations to water base, saponification agents (soda, potash, silicate, phosphate, borate or carbonate), chelation and surfactants.
- EP-A-0 564 402 published after the priority date which benefits part of this application, describes in synthesis examples 2 and 3 of detergents added, after purification, to water (15% by weight of the final composition).
- the subject of the invention is therefore a method of degreasing the surface of a metallic object, ceramic, glass or plastic, which consists of apply to it a composition comprising a compound amphiphilic formula A-B, A being a lipophilic radical and hydrophobic and B a hydrophilic radical.
- the process is characterized in that it consists in using a composition comprising at least 25% and preferably at least 60% by weight of the amphiphilic compound of formula A-B then serving as solvent, so as to form an oil or fat amalgam - compound A-B thanks to the radical A, then rinse the surface to water so as to remove the amalgam from the surface, this elimination being made possible thanks to the hydrophilicity of the amalgamation due to the presence of the radical B.
- the amphiphilic solvent of structure A-B is chosen so that Part A has the best affinity for the oil considered. A priori, this amphiphilic solvent will be used pure. If this is not possible, it will be added of one or of co-solvents, taking care to put the least possible. Indeed, if the amphiphilic solvent is too diluted, it will no longer be able to play its role of amalgam formation and will play the classic (non-performing) role of surfactant. In conventional detergency, the surfactant comes adsorb on oil to minimize tension interfacial between the oil and the aqueous solution. Task oil comes off giving a drop so as to minimize interfacial tension. The surfactant thus makes it possible to obtain an oil dispersion in the aqueous solution. The rates of surfactants used are generally weak (some for hundred).
- amphiphilic solvent on the layer fat aims to increase the hydrophilicity of this layer.
- the amphiphilic solvent dissolves the fatty layer well or is very miscible with it, due to its segment A having a very good affinity for oils and fats. This very good dissolution or miscibility leads to the formation of an amalgam of oil-amphiphilic solvent. As a result of its hydrophilicity, this amalgam is easily eliminated by a simple rinse with water.
- Part B of the amphiphilic solvent is for example an ionic head or an ethoxylated chain.
- alkylene glycol etheroxides because of their long hydrocarbon chain, in particular having 11 to 18 carbon atoms, and the presence of an ethoxylated segment, are very effective in degreasing a surface.
- alkylene glycol etheroxides in which R 1 has at least 10 carbon atoms.
- the hydrocarbon group which constitutes R 1 or R 2 may in particular be alkyl, alkenyl, cycloalkyl, alkylaryl and aralkyl, and in particular substituted by a hydroxyl group or by a hydroxyalkoxyl group.
- R 1 can come from an acetate, a propionate, a butyrate, a valerate, a cyclopentacarboxylate, a caproate, a cyclohexacarboxylate, an enanthoate, a benzoate, d 'a caprylate, a perlagonate, a caprate, a laurate, a myristate, a palmitate, a stearate, an oleate.
- R 2 can be methyl, ethyl, propyl, amyl, octyl, decyl, dodecyl, tetradecyl, hexadecyl, octadecyl, vinyl, octyl, pentadecyl, oleyl.
- R 1 is a ricinyl radical, it is a product derived from castor oil of natural origin.
- the most common and therefore preferred alkylene glycol etheroxides are those in which R 3 , R 4 , R 5 and R 6 are hydrogen atoms.
- the invention also relates to a composition of degreasing as defined in claim 4.
- the composition makes it more fluid, and therefore, to facilitate its subsequent elimination by water.
- the composition is heterogeneous. A simple shaking makes it homogeneous for many hours. This homogenization can be facilitated by heating at a temperature between 30 and 60 ° C and preferably between 30 and 40 ° C.
- the step of rinsing with water often gives a gel viscous, which can be removed by mechanical action (friction or jet under high pressure).
- an agent promoting the miscibility of compound A-B, especially alkylene glycol etheroxide in water.
- This agent can be a lower alcohol, in particular an alkanol or a glycol.
- Diacetone alcohol a alkylene glycol such as an alkyl glycol, hexylene glycol, a branched alkanol such as secondary butanol, or even etheroxides such as monobutyl oxide diethylene glycol or other glycol etheroxides particularly interesting due to their low toxicity.
- the amount of miscibility promoting agents is advantageously between 10 and 20% by weight.
- a composition according to the invention may comprise by weight from 60 to 75% of the etheroxide alkylene glycol or a mixture thereof, from 15 to 20% of water and 10 to 20% of an agent promoting the miscibility of alkylene glycol etheroxide in water.
- the invention also relates to a method of degreasing the surface of an object, which consists of apply per square centimeter of the surface, from 0.2 to 1 mg of a compound A-B, in particular of an alkylene glycol etheroxide as mentioned above, or of a composition such as mentioned above.
- the duration of application of the product amphiphilic A-B on the fatty layer can be between at least about a second and 10 minutes or more following the extent of the surface to be cleaned.
- this application can be carried out by immersion, by sprinkling or rubbing the surface using a damp cloth. You can also use a water jet.
- Alkylene glycol etheroxides called "ethoxylated metiloils" were used which can be obtained from the company Seppic, 75 quai d'Orsay, Paris France. These compounds have 2 to 5 moles of ethylene oxide.
- R 2 is methyl there and R 1 is a mixture of C 11, C 13 and C 18 monocarbonylated hydrocarbons. They are essentially methyl esters. On average, either 2 moles of ethylene oxide or 5 moles of ethylene oxide were added to the metiloil.
- Ethoxylated metiloils are therefore mixtures complex by the composition of the metiloil and by the degree of ethoxylation. This complexity leads to heterogeneity of the product for metiloil 5 OE. So we have initially sought to make this product homogeneous (existence of a single phase at room temperature either 20 ° C).
- Métiloil 5 OE remains heterogeneous at temperature ambient. Above 20% water, it leads to a gel. We therefore prefer to use the minimum possible rate of 15% of water by weight.
- the second step of the process consists in rinsing with water the coated surface of the amalgam oil - amphiphilic solvent. This amounts, among other things, to adding water to the Metiloil 5 OE formula, therefore to obtaining a percentage of water greater than 20% and relapsing into the formation of the lamellar phases. This is indeed what happens during rinsing with water: we observe the formation of a viscous gel on the surface.
- a co-solvent of the alcohol or glycol type can be added. Diacetone alcohol, hexylene glycol, secondary butanol or even diethylene glycol monobutyl ether can be used, for example.
- This latter solvent which is part of the family of glycol ethers, turns out to be particularly advantageous because of its very low toxicity and its superior performance compared to other alcohols or glycols.
- the minimum amount of diethylene glycol monobutyl ether (DGB) is 15% by weight.
- the following mixtures were made: 77% Metiloil 5 OE + 15% water + 8% BDG. 75% Metiloil 5 OE + 15% water + 10% BDG. 70% Metiloil 5 OE + 15% water + 15% BDG.
- the dilution in water of the first two formulas leads to the formation of a milky emulsion.
- the dilution in the water of the 3rd formulation leads to obtaining a translucent phase characteristic of microemulsions. It is the desired result.
- NM 22 S steel plate On a NM 22 S steel plate, dimensions 10 x 10 cm, degreased by the hot trichloroethane cycle, cold, vapor phase, deposit a thin layer of petroleum jelly. Using a cloth soaked in the above mixture, the plate coated with vaseline oil is rubbed. After 2 or 3 successive passages, the plate is placed under a jet of water (15 seconds). We then obtain a very good spreading of the film of water which is significant of a clean surface. The angle of contact with a drop of water deposited on such a surface is between 50 and 60 °.
- Example 1 The formula of Example 1 is diluted for half with water. We therefore prepared and used in this example, the following formulation: Métiloil 5 OE 35% diethylene glycol monobutyl oxide 7.5% water 57.5%
- Example 1 As described in example 1, the test is carried out degreasing. We obtain an efficiency similar to Example 1.
- Example 2 The formula of Example 2 is diluted for half with water. We therefore use, in this example, the following formulation: Metiloil 5 OE 17.5% diethylene glycol monobutyl oxide 3.5% water 79%
- the amount of Metiloil 5 OE is greatly reduced and we arrive in the area of use of a surfactant (maximum rate) in detergency.
- sodium dodecylbenzenesulfonate is used as the amphiphilic solvent.
- This compound AB has a lipophilic part (dodecylbenzene) and a hydrophilic part (ionic head sulfonate of Na). This compound is a solid at room temperature. It must therefore be dissolved in a liquid before it can be used.
- the following formulation was prepared and used: Na dodecylbenzenesulfonate 42.5% diethylene glycol monobutyl oxide 15% water 42.5%.
- the mixture obtained is much more fluid than the 50% mixture of Na dodecylbenzenesulfate + 50% water. This is due to the 15% monobutyl oxide in the diethylene glycol. This fluidity allows good spreading cloth as in example 1.
- Example 1 As described in example 1, the test is carried out degreasing. We obtain an efficiency similar to Example 1.
- MeT 1 to MeT 8 mixtures called MeT 1 to MeT 8 are carried out, in accordance with the weight formulations indicated below. These mixtures are homogeneous products, which are stable at low temperature (around 5 °) and which are not destabilized by infinite dilution with water (with the exception of Met 1).
- Example 5 We operate as in Example 1 and using the MeT 2 or MeT 7 mixtures, but applying the product by spray or soak (and no longer with a cloth), results are absolutely identical to those obtained at Example 5.
