Definitions

• the invention relates to a method for packaging mixtures of substances, the effect of a vacuum packaging.
• the object of the present invention was therefore to provide a technically easy to carry out process for the original packaging of mixtures of substances.
• the invention accordingly relates to a process for packaging mixtures of substances which contain 10 to 95% by weight of an alkaline substance and 0.2 to 30% by weight of an oxidizable organic substance which are in powder form and / or granulated with an average particle diameter of 0.1 to 2.5 mm are present.
• Gas-tight bags are filled with at least 50 g of these substance mixtures at 70 to 95% by volume and then stored quasi-adiabatically, which forms a packaging that is firmly attached to the product.
• pulverulent and / or granulated substance mixtures which contain 10 to 95, preferably 25 to 80% by weight of a alkaline substance and 0.2 to 30, preferably 1 to 10 wt .-% of an oxidizable organic substance, preferably dust binders or surfactants. It is particularly important that the substance mixtures have a large surface area, it should be an average particle diameter in the range from 0.1 to 2.5 mm.
• the substance mixtures can contain other ingredients that are usual for detergents and cleaning agents, such as, for example, organic / inorganic salts, complexing agents, corrosion inhibitors, optical brighteners, oxidizing agents, perfume oils, inert substances, enzymes, foam and / or graying inhibitors in the usual amounts, and also 0 to Contain 2 wt .-% water, preferably the mixtures are anhydrous.
• other ingredients that are usual for detergents and cleaning agents, such as, for example, organic / inorganic salts, complexing agents, corrosion inhibitors, optical brighteners, oxidizing agents, perfume oils, inert substances, enzymes, foam and / or graying inhibitors in the usual amounts, and also 0 to Contain 2 wt .-% water, preferably the mixtures are anhydrous.
• the alkaline substances to be used according to the invention are preferably alkali and alkaline earth hydroxides as well as alkali carbonates and / or alkali silicates. Mixtures of substances containing 20 to 95% by weight sodium hydroxide are particularly preferred.
• Dust binders may preferably be present as oxidizable organic substances, which in the sense of the present application means compounds which reduce the dusting of the substance mixture during transferring and processing. They are therefore added to the powdery substances during the manufacturing process.
• Preferred dust binders are alkylbenzene, paraffin oils and / or polyethylene terephthalate.
• surfactants such as, for example, fatty alcohol ethoxylates and alkylbenzenesulfonates, can also be used. lenside.
• anionic surfactants are alkyl benzenesulfonates, alkanesulfonates, olefin sulfonates, alkyl ether sulfonates, glycerol ether, ⁇ - methyl ester sulfonates, sulfofatty acids, alkyl sulfates, fatty alcohol ether sulfates, Gly cerinethersulfate, Hydroxymischethersulfate, monoglyceride (ether) sulfates, fatty acid amide (ether) sulfates, mono- and Dialkylsulfosuccinates, mono- and dialkylsulfosuccinamates, sulfotriglycerides, amide soaps, ether carboxylic acids and their salts, fatty acid isethionates, fatty acid sarcosinates, fatty acid taurides, acyl lactylates, acyl tart
• nonionic surfactants are fatty alcohol polyglycol ethers, alkylphenol polyglycol ethers, fatty acid polyglycol esters, fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, alkoxylated triglycerides, mixed ethers or mixed formals, alk (en) yl oligoglycosides, fatty acid-N-alkylglucose glycolates (especially vegetable hydrolysic acid based), protein , Sugar esters, sorbitan esters, polysorbates and amine oxides. If the nonionic surfactants contain polyglycol ether chains, they can have a conventional, but preferably a narrow, homolog distribution.
• cationic surfactants are quaternary ammonium compounds and ester quats, in particular quaternized fatty acid trialkanolamine ester salts.
• amphoteric or zwitterionic surfactants are alkyl betaines, alkyl amido betaines, aminopropionates, aminoglycinates, imidazolinium betaines and sulfobetaines.
• the surfactants mentioned are exclusively known compounds. With regard to the structure and manufacture of these substances, reference is made to relevant reviews, for example, J.Falbe (ed.), “Surfactants in Consumer Products”, Springer Verlag, Berlin, 1987, pp. 54-124 or J.Falbe (ed.), “Catalysts, Tenside und Mineralöladditive ", Thieme Verlag, Stuttgart, 1978, pp. 123-217.
• the surfactants can be used individually or in any mixtures that make sense depending on the application.
• the powdery and / or granulated ingredients are mixed intensively. Depending on the desired effect, all ingredients are combined with the surfactants and / or dust binders directly or in a highly finely divided form.
• the substance mixtures are filled into gas-tight bags in the usual way, which are then sealed. At least 70, preferably 80% by volume of the bags should be filled with the corresponding mixture of substances.
• the bags are preferably stored for a period of 5 to 35 days, at a temperature in the range from 15 to 60, preferably 25 to 55 ° C.
• the effect during storage can be explained as follows: Due to the large surface area and the alkalinity of the mixture of substances, the dust binders and / or surfactants are oxidized and the temperature inside the bags increases. After reaching a critical temperature, this reaction spreads as a chain reaction over the entire contents of the bag. It is a quasi-adiabatic storage, since the heat dissipation is negligible compared to the heat generation slowly. So that this chain reaction can proceed relatively completely, container sizes of at least 50 g, but preferably greater than 100 g, are advantageous. In the course of this chain reaction, the corresponding soaps can form, for example, from the hydrocarbons (paraffin oil, alkylbenzene).
• just enough dust binders can be provided in the formulation that they are completely converted into the corresponding soaps. If it is necessary for application reasons that the product contains dust binders, an excess of dust binders is provided in the formulation. After storage, products are obtained in which the packaging lies directly against the respective goods, so that the effect of vacuum packaging is created.
