Definitions
- the invention relates to a demulsifying cleaning agent which is particularly suitable for removing oil and grease contamination.
- the area of use of such demulsifying cleaning agents is in particular the area of vehicle washing systems, such as Car wash systems or train cleaning systems are provided, in which high-pressure cleaning devices are often used.
- the cleaning agents used hitherto which are used to clean painted and unpainted surfaces of vehicles, engines, floors, facades, aircraft, etc., remove the oil and fat-containing contaminants by emulsifying from the surface and transfer the oil and fat components and the contaminant particles contained therein into the transport medium water.
- the focus of these cleaning agents is only on the complete removal of dirt. Due to the stable emulsification of the oil and fat components, but also the at least partial dispersion of the solid particles, a separation of these contaminants from the waste water in the cleaning system is not possible or only with great effort.
- EP-A 213 554 also discloses a demulsifying cleaning agent with a surface moisturizing effect, the composition of which is particularly suitable for the absorption of fats and oils and for cleaning vertical surfaces, the so-called surface moisturizing effect being achieved by the special formulation of the cleaning agent becomes.
- this cleaning agent separates the oil and fat components of the impurities through the demulsifying effect, so that these components can be separated from the dirty water phase.
- the cleaning effect of these cleaning agents is overall unsatisfactory, especially with regard to the removal of mineral soiling, e.g. Dusts, pollen etc.
- the cleaning agent of the present invention should also be particularly suitable for use in high-pressure cleaning devices and brush washing systems.
- the separation effect in the wastewater should in particular also meet the new requirements for the wastewater to be discharged into the public sewer network, as specified, for example, in Appendix 49 of the General Framework Administrative Regulation on Minimum Requirements for the Discharge of Wastewater into Waters of December 19, 1989 is.
- Cleaning agents of this type are ideally suited to cleaning oil and fat-containing contaminations, which in particular also contain mineral contaminants, such as dusts, pollen, etc., in a wide temperature range of approx. 15 to 70 ° C.
- the hydrocarbons, fats and oils of any kind emulsified during the cleaning process become instantly separated from the wastewater at rest, and so completely that the separable demulsified wastewater fully complies with the latest wastewater regulations.
- the cleaning agents according to the invention achieve a very good cleaning effect with economical use of cleaning agents.
- An essential advantage of the cleaning agent according to the invention is that the demulsifying properties are not lost even over the large temperature range of 15 to 70 ° C., which is not guaranteed with conventional cleaning agents of this type.
- 15 ° C is usually the water temperature that the cold water from the public water supply has.
- the temperature of 70 ° C is usually not exceeded when a hot water high pressure jet impacts a cleaning object.
- the cleaning agent according to the invention can be used universally for all possible types of dirt, in particular also for mixed soiling from oil and fat as well as mineral soiling, the demulsifying effect is not lost.
- the central feature here is the mixing ratio of the nonionic surfactants, which is expressed by the HLBg value.
- the ratio of anionic and non-ionic surfactants is also critical, since incorrect mixing here can also disrupt the demulsifying effect.
- the cleaning agents according to the invention can be present both in solid form and in liquid form.
- the cleaning agent according to the invention can be formulated as a concentrate or as an agent prepared with water.
- a solubilizer is added in an amount of about 0.5 to 18% by weight.
- a particular advantage of the present detergent mixtures is that they can be manufactured without phosphate.
- alkylbenzenesulfonates are preferred as the anionic surfactant, so that preferred cleaning agents predominantly contain those as anionic surfactants, the weight ratio V between nonionic and anionic surfactants in this case preferably being 3.5 to 12.5 .
- dialkyl sulfonate succinates have also proven themselves as anionic surfactants, and in the event that these anionic surfactants are predominantly present in the cleaning agent, a weight ratio V of approximately 2.9 to 11 is selected.
- anionic surfactants is the alkylnaphthalenesulfonates, in which case the weight ratio V is then set to about 3.5 to 12.
- alkyl sulfonates Another group of substances with which very good cleaning effects are achieved are the alkyl sulfonates, and in this case the weight ratio V will preferably be about 4 to 16.
- the salts of sodium and ammonium and of triethanolamine are preferred. It was also found that the demulsifying effect of the cleaning agents according to the invention is somewhat concentration-dependent and, surprisingly, the concentration with which the best demulsifying effect is obtained coincides with the concentration range which results as the minimum surfactant concentration range.
- the nonionic surfactants are preferably selected from the group of C 1 -C 8 oxo alcohols, which alone or in a mixture with C 1 to can provide the total nonionic surfactant content.
- Corrosion inhibitors for light and colored metals are added.
- the proportion by weight of these substances is frequently between 0.1 and 25% by weight of the cleaning agent.
- colorants and fragrances are usually added to the cleaning agent, but they play a minor role in terms of their weight percentage.
- the latter are usually between 0.0005 and 0.4% by weight.
- additives such as e.g. Complexing agents, corrosion inhibitors, dyes and fragrances for the cleaning agent according to the invention do not change its basic structure and characteristics, but that only additional, already known side effects are used here.
- the complexing agents are usually selected from the group EDTA, NTA, phosphonic acids and their soluble salts.
- the substances can be used individually or as a mixture.
- the cleaning agent according to the invention is used as a solid agent, so-called fillers are often added, which can make up between 10 and 80% by weight of the cleaning agent.
- Suitable fillers are soda, borax, sulfates and urea.
- the cleaning agent can also have an alkaline content added, which can be, for example, up to 9% by weight of NaOH.
- the cleaning agent For cleaning applications with a different approach, it may be advisable to give the cleaning agent an acidic pH, and in this case an inorganic or organic acid is added, which can make up to 25% by weight of the cleaning agent.
- solubilizers are used, as described above.
- the group of cumene sulfonates and their salts has proven to be favorable.
- formulations 1, 3 and 4 relating to liquid detergents and formulation 2 a solid detergent.
- Cin.ic alkyl sulfonate Na salt 1.5% Cin.ic alkyl sulfonate Na salt; 65% solution
- Alkyl radical C 12
- the formulation 5 named below again relates to a liquid cleaning agent and this cleaning agent was compared with the cleaning effect of a comparison formulation which is a conventional, highly effective car shampoo according to the prior art.
- alkylbenzenesulfonate approx. C-, 2nd
- the cleaning agent according to recipe 5 and according to the comparison recipe were examined for their cleaning effect as a function of the cleaning time.
- the concentration of the cleaning agent was varied between 0.5% and 50%. The results are shown in the table below.
- the number of times is defined as the ratio of the cleaning time of the recipe 5 required for complete degreasing to the time required to achieve complete degreasing with the comparison recipe.
- test tubes 200 ml long, 15 mm in diameter
- 50 ml detergent solution (recipe 5) in concentrations of 5%, 3%, 2%, 1%, 0.5%, 0.25%, 0.1% and 0.05% and 0.2 g of red-colored spindle oil were added.
- Each value is the average of three measured values.
- recipe 5 The optimal application concentration of recipe 5 is 0.5%, but it can also be processed with acceptable demulsifying properties in the range of 0.25 - 2.5%.
- test tubes 200 ml long, 15 mm in diameter
- 70 ml detergent solution (recipe 5 in demineralized water) in concentrations of 5%, 4%, 3%, 2%, 1%, 0.5%, and 0.25 % and heated in a saturated water vapor atmosphere in an autoclave to 135 ° C. at an operating pressure of 3-4 bar for 15 minutes.
- test conditions correspond approximately to those in a conventional hot water high-pressure cleaning device.
- the detergent solution was removed from the test tubes and the residues / deposits on the glass walls were assessed visually.
