Definitions

  • the present invention relates to a liquid composition having synergistic dissolving effect and use of the same to remove pollutants strongly bound to surfaces.
  • micellar-structure aqueous solutions of surface active agents may be applied to clean different surfaces.
  • surface active agents surfactants
  • solubility of substances otherwise immiscible with water or only sparingly miscible with water increases if the same are added to micellar solutions, since the oleophilic components get solubilized in the core of the micelles.
  • the surfactant concentration is considerably higher than cmc (critical micellization concentration) and the micellar system contains an additional auxiliary surfactant (for example an aliphatic alcohol of medium chain length such as n-butanol, n-pentanol and so forth), then further addition of the organic component leads to conversion of the swollen micellar system into an oil-in-water (o/w) type microemulsion.
  • an additional auxiliary surfactant for example an aliphatic alcohol of medium chain length such as n-butanol, n-pentanol and so forth
  • Combined concentration of the surfactant and the auxiliary surfactant (co-surfactant) at the observed point of microemulsion formation is called the critical microemulsion concentration [1-5].
  • microemulsions being molecularly heterogeneous systems with nanostructured discontinuities, form spontaneously from a polar liquid (generally water), an immiscible apolar liquid and some type of surfactant (anionic, cationic or non-ionic), without an input of energy.
  • a polar liquid generally water
  • an immiscible apolar liquid generally water
  • some type of surfactant anionic, cationic or non-ionic
  • Inverse micelles may form in the presence or absence of water, but in the latter case the cmc is not well defined and the systems are highly polydisperse.
  • water i.e. changing the H 2 O/surfactant molar ratio, the size and shape of the forming micelles can be affected and regulated fairly arbitrarily [6,7].
  • microemulsions are excellent cleaning supplies and can be suitable to dissolve even surface bound (sun-dried) dyestuff in some cases.
  • microemulsions imply considerable environmental load since they contain aromatic or aliphatic hydrocarbons in an amount up to 10-20% which contaminate the environment during application, thus, their use is limited.
  • the object of the invention was attained by providing a liquid composition having synergistic dissolving effect, which comprises
  • the liquid composition of the invention can be used for cleaning surfaces contaminated with dyestuff, heavy oil and/or bitumen.
  • the invention is directed to a liquid composition having synergistic dissolving effect, comprising
  • the invention is directed to the use of the liquid composition according to the invention for cleaning various surfaces contaminated with dyestuff, heavy oil and/or bitumen.
  • Component a) of the liquid composition of the invention is an alkylene glycol alkyl ether of unlimited water miscibility of general formula (C 3 -C 6 -alkyl)-(O-CH 2 -CH 2 ) n -OH, where the value of n is 1 to 5, or a mixture thereof.
  • the C 3 -C 6 -alkyl group in the above formula is a linear or a branched saturated hydrocarbon group containing 3 to 6, preferably 4 or 5, most preferably 4 carbon atoms.
  • the C 3 -C 6 -alkyl specifically includes propyl, isopropyl, n-butyl, sec-butyl, terc-butyl, isobutyl, n-pentyl, isopentyl, n-hexyl, isohexyl groups, and the like.
  • the hydrocarbon chain is preferably non-branched (normal).
  • the alkylene glycol part of the above component a) can be mono-, di-, tri-, tetra- or pentaglycol.
  • the amount of component a) ranges from 40 to 80 % of the total mass of the composition.
  • Component b) of the composition of the invention can be anionic or non-ionic surfactant, or a mixture thereof.
  • surfactant preferably Ufasan TEA (Brennteg Hungária Kereskedelmi Kft), 3EO (sodium lauryl ether sulfate, Biesterfeld Kft), Triton X100 (ICI Chemicals and Polymers Group), AOT (sodium salt of bis-(2-ethylhexyl) sulfosuccinate; Fluka), DAM (dialkyl ammonium-metasulfate; Stepan Company, Grenoble, France), Lutensol*GD70 (BASF), UFABLEND (Unger Fabrikker A.S.), or the mixture of two or more of the above surfactants can be applied.
  • Mixtures of Ufasan TEA and 3EO or Ufasan TEA and Triton X100 are the most preferred.
  • liquid compositions of the invention show synergistic dissolving capacity in the range of mass ratios of component a) to component b) between 4:1 and 80:1.
  • the liquid composition of the invention comprises water as component c) in an amount as required to 100%.
  • the liquid compositions of the invention may optionally comprise an alkali metal hydrogen carbonate such as sodium or potassium hydrogen carbonate or ammonium hydrogen carbonate as component d) in an amount up to 1.0 % of the total mass of the composition.
  • an alkali metal hydrogen carbonate such as sodium or potassium hydrogen carbonate or ammonium hydrogen carbonate as component d) in an amount up to 1.0 % of the total mass of the composition.
  • Sodium hydrogen carbonate is preferred.
  • the liquid compositions of the invention can be produced by mixing component a) alkylene glycol ether and component c) water; optionally adding component d) to the resulting alkylene glycol/water mixture during continous, vigorous mixing, and homogenizing it; finally, adding component b) surfactant and mixing the system until complete dissolution is achieved.
  • the so-obtained clear liquid has a pale yellow tone.
  • alkylene glycol ethers used as component a) of the liquid compositions of the invention are known commercial compounds (produced by BASF for example), or can be produced by analogy with the known compounds, using methods known from the prior art.
  • the surfactants used as component b) of the liquid compositions of the invention are known commercial products as well.
  • the alkali metal and ammonium hydrogen carbonates, used optionally as component d), are similarly known compounds.
  • liquid compositions of the invention are not fully homogeneous on a molecular level - although seem to be clear solutions -, but the systems contain nano-sized discontinuities the structure of which is not fully clarified up to date.
  • the liquid compositions of the invention contain so-called clusters of the size of 10-12 nm, proven by us in dynamic light scattering experiments. While we do not wish to limit the present invention by theories, we suppose that the above cluster structure contributes to the synergistic effect and largely promotes loosening and dissolving of the dry dye coat layers, oily and tarry contaminations.
  • liquid compositions (or complex mixtures) of the invention are well applicable to public buildings, street sculptures, privately owned objects (cars, doors and windows of buildings), transportation vehicles (bus, train, ship), infrastructure appliances of the transportation, that are coated with dye or oily contaminations.
  • the invention is directed to the use of the above liquid composition for cleaning surfaces contaminated with dyestuff, heavy oil and/or bitumen.
  • the liquid composition of the invention is preferably used for cleaning graffiti dye contaminated surfaces.
  • the surface to be cleaned can be smooth or porous, such as porous ceramic and/or plastered wall, or it can be granite, limestone, cast stone or concrete surface either.
  • the combined dissolving effect of the components of the liquid composition of the invention - below demonstrated by examples - is synergistic, i.e., it is greater than the sum of the separate dissolving effects of the components.
  • the composition does not contain aromatic or aliphatic hydrocarbons thus, the environmental load effect thereof is minimal and after use it can be removed by washing with water or blowing with steam and can be collected.
  • a further non-negligible advantage is that the concentration of the expensive surfactant component in the liquid composition of the invention is much smaller than in the known products used for similar purpose.
  • Liquid compositions of the invention are prepared as shown below: Composition 1 Component Amount (% by mass) butyl diglycol 45.0 UFABLEND 4.0 NaHCO 3 0.5 tap water 50.5 Composition 2 Component Amount (% by mass) butyl diglycol 45.0 UFABLEND 8.0 NaHCO 3 0.5 tap water 46.5 Composition 3 Component Amount (% by mass) butyl diglycol 45.0 Ufasan TEA 6.0 NaHCO 3 1.0 tap water 48.0 Composition 4 Component Amount (% by mass) butyl diglycol 45.0 Ufasan TEA 1.0 3EO 5.0 NaHCO 3 1.0 tap water 48.0 Composition 5 Component Amount (% by mass) butyl diglycol 45.0 Ufasan TEA 3.0 Triton X100 3.0 NaHCO 3 0.5 tap water 48.5
  • composition 1 as extraction liquid
  • the calculation is:
  • the measured dye concentration (c pract ) is 88.6 mg/L.
  • compositions 2 to 5 of the invention We determined also the dye dissolving capacity for compositions 2 to 5 of the invention according to the above. The results are summarized below. Sample (c pract -c add )/c add Composition 1 2.002 Composition 2 2.196 Composition 3 2.411 Composition 4 2.038 Composition 5 2.271
  • compositions 1 to 5 had proven to be the most effective liquid compositions of the invention. Among them, the strongest synergistic effect has been found for composition 3, where the relative excess dissolving capacity (c pract -c add )/c add was equal to 2.411. The relative excess dissolving capacity of compositions 1 to 5 of the invention and their synergistic effect is represented graphically in Figure 1 .
  • the surfactants applied to prepare the liquid compositions of the invention are: AOT, DAM, Lutensol*GD70, UFABLEND.
  • the liquid compositions contained one, two or three of the above surfactants (surfactant mixtures) and the amount and ratio of them were varied as well within the separate series. The results are summarized shortly below.
  • the synergistic effect is the strongest at lower (45 % by mass) butyl diglycol content. Synergistic effect is not observed in the presence of 80 or higher % by mass of butyl diglycol ( Figure 2.a ). The amount of the surfactant does not influence significantly the extent of the synergistic effect ( Figure 2.b )
