Definitions

  • the invention relates to a surfactant mixture for the mechanical cleaning of hard surfaces, in particular bottles and dishes in the alkaline to highly alkaline range of the cleaning liquor.
  • the system must also be as low-foam or foam-free as possible, since excessive foam formation can lead to malfunctions in the operating behavior of the system, for example if the dirt accumulating in the foam layer cannot be removed sufficiently. Additional tendencies towards foam formation are caused by the impurities carried in by the items to be cleaned, especially by protein-containing residues on the items to be cleaned. In the case of bottle cleaning, this also applies in particular to the labels to be removed, through which the glue residues and residues of printing inks, including the surfactant auxiliaries contained in the latter, are introduced into the cleaning liquor.
  • non-ionic surfactants with low-foaming characteristics as cleaning agents for hard surfaces in alkaline baths. These are, in particular, addition products of ethylene oxide and / or propylene oxide onto amines, longer-chain fatty alcohols or alkylphenols, polyglycol ether formals or acetals or block copolymers of ethylene and propylene oxide.
  • Such surfactant systems can be adjusted, in particular by suitable variation of the ethylene oxide and propylene oxide proportions, to the lowest possible foam tendency and increased cleaning action, an excess weight of the propylene oxide favoring the former property and an excess weight of the ethylene oxide promoting the latter property.
  • the task was therefore to improve the dirt-holding capacity of such mixtures without having to accept the disadvantage of substantivity.
  • A means an anion
  • Such an average can be an integer or a fraction.
  • the ratio of the ethylene oxide to propylene oxide units should preferably be in the range from 0.8 to 1.5.
  • non-ionic surfactants can also be present as mixtures within groups A 1 ), A 2 ) or A 3 ) or else between groups A 1 ), A 2 ) and / or A 3 ).
  • the non-ionic surfactants of group A 1 ) are preferred.
  • the surfactant mixture contains a quaternary ammonium compound B) of the formula as a cationic component in which R 4 and R 5 , the same or different, are an alkyl radical with 1 to 8 C atoms, preferably with 4 to 6 C atoms, R 6 is an alkyl radical with 1 to 8 C atoms, preferably 1 to 6 C atoms , and R 7 is an alkyl radical having 1 to 4 carbon atoms or a benzyl radical.
  • A is an anion, preferably a chloride or bromide anion or one of the formula CH 3 OSO 3 -.
  • composition of the surfactant mixture is essential for the advantageous properties.
  • the ratio of components A: B should be in the range from 20:80 to 95: 5% by weight, preferably 40:60 to 85:15% by weight: -%, lie.
  • the surfactant mixtures can be used as a mixture of components A + B in undiluted, liquid form. However, they can also be used in the form of aqueous concentrates, for example for better meterability, if appropriate also with the addition of an organic solvent. Components A and B can of course also be added separately to the aqueous cleaning liquor.
  • the application concentration is expediently 0.05 to 10 g of the mixture A + B per liter of cleaning liquor, preferably 0.1 to 2 g per liter.
  • the application concentrations mentioned are non-critical statements, since the amount varies to a certain extent according to the type to be cleaned Surface and depending on the type and extent of contamination.
  • further additives and auxiliaries can be added to the surfactant mixtures according to the invention in the production of commercially available formulations.
  • these include dyes, fragrances, corrosion inhibitors and disinfectants.
  • the known builders which are optionally also complexing agents, should also be mentioned here.
  • the condensed phosphates such as tripolyphosphates and in particular pentasodium triphosphate, come into consideration.
  • these are complex-forming aminopolycarboxylic acids and their salts, such as, in particular, alkali metal salts of nitrilotriacetic acid and ethylenediaminetetraacetic acid, and also also complex-forming hydroxycarboxylic acids and polymeric carboxylic acids, such as citric acid, tartaric acid and the like.
  • Another class of complexing builders are polyphosphonic acid salts, such as the alkali salts of aminophosphonic acid.
  • builders such as silicates, for example sodium metasilicate, carbonates, bicarbonates, borates and citrates, can also be added. With the aid of such additives, the surfactant mixtures according to the invention can optionally be converted into powder form and can also be used in this form.
  • the surfactant mixtures according to the invention are suitable for the mechanical cleaning of hard surfaces in alkaline liquors. This applies to cleaning in household dishwashers and so-called commercial cleaning systems.
  • the mixtures are particularly suitable for industrial cleaning systems for hard surfaces, for example dishwashing and bottle washing systems, which operate under high mechanical liquor movements in continuous operation and in highly alkaline liquors at pH values of # 10, preferably> 12.
  • the necessary alkaline additives preferably sodium or potassium hydroxide for the highly alkaline pH range of the liquor, can be dissolved in the aqueous cleaning liquor before the surfactant mixture according to the invention is introduced. However, they can also be added directly to the surfactant mixture and metered together with it.
  • the alkaline agent is expediently added in the form of powder, flakes or cookies.
  • the mixtures according to the invention have the low foaming tendency which is indispensable for industrial cleaning systems and which, as a rule, makes the addition of additional defoamers superfluous.
  • foam-suppressing agents Only in the case of extremely high movements of the liquor or in the presence of soiling with an extremely high tendency towards foaming can the addition of foam-suppressing agents be expedient, which must have the required stability to alkali.
  • foam-suppressing agents are, for example, orthophosphoric acid esters, ethylenediamine condensation products with ethylene oxide and propylene oxide and also fatty alcohols.
  • the surfactant mixtures according to the invention as cleaning agents for the mechanical cleaning of hard surfaces, in particular with regard to the high demands placed on industrial cleaning systems, also have the following significant advantages: the mixtures are not only resistant to alkali, but also together with Alkali stable in storage for long periods. They have an extremely low tendency to foam formation not only at the working temperatures of such cleaning systems, i.e. h., above about 40 ° C, but also at low temperatures, so that when refilled with cold water and heating there is no formation of disruptive foam, which can then lead to over-foaming or to disturbances in the circulation of the system.
  • the excellent dirt absorption capacity allows long service life in the system until it is refilled without impairing the cleaning effect.
  • Clean 0.5 liter beer bottles are filled with 100 ml of the cleaning liquor and shaken vigorously 5 times with a cork stopper. After a short period of action (approx. 1 minute), the shaking process is repeated 5 times and the detergent-containing cleaning liquor is then poured out. This is followed by rinsing 4-5 times in succession with 100 ml of distilled water until pH 7 is reached.
  • Drop formation indicates substantivity on the bottle walls (column 5 of the table).
