Definitions

• the object of the present invention was therefore to develop an agent with better properties overall.
• the agent according to the invention has an exceptionally high cleaning ability even on heavily oil and grease soiled windows, such as motor vehicle windscreens. It can be easily applied to the panes without fear of running down or dripping. Despite its pasty consistency, the product can be easily distributed over a large area. After drying, the back polish the stands easily and almost dust-free, and the result is completely clear streak-free and residue-free surfaces.
• the agents preferably contain only gasoline as the organic solvent, in particular those qualities which have boiling ranges between 120 and 250 ° C., preferably between 140 and 180 ° C. For reasons of smell, dearomatized gasoline types and synthetic isoparaffins are preferred.
• solvents from the group of alcohols, ketones and glycol ethers can also be used in the agents; however, their share always makes up less than half of the gasoline share.
• the boiling point of these solvents is between 55 and 250 ° C.
• solvents are acetone, isopropanol and ethylene glycol monobutyl ether.
• the amount of gasoline in the compositions is 2 to 30% by weight, preferably 3 to 20% by weight and in particular 4 to 12% by weight.
• the other organic solvents mentioned can contain 0 to 10, preferably 0 to 5% by weight.
• the calcium carbonate used in the agents as an abrasive component is microcrystalline natural or, preferably, synthetic calcium carbonate. Fine-particle material with a weight average grain size between 0.2 and 10 ⁇ m is suitable. 98% by weight of the calcium carbonate should have grain sizes below 300 ⁇ m, preferably below 200 ⁇ m and in particular below 100 ⁇ m.
• the share of Calcium carbonate in the compositions is 5 to 40% by weight, preferably 10 to 30% by weight and in particular 15 to 25% by weight.
• Low viscosity silicone oils for example polydimethylsiloxanes, with viscosities of 20 to 1000 mPas, preferably 30 to 500 mPas and in particular 50 to 150 mPas at 20 ° C. are suitable for the agents according to the invention.
• Their proportion of the agents is 0.2 to 2.5% by weight, preferably 0.3 to 1.8% by weight and in particular 0.7 to 1.3% by weight.
• Suitable anionic emulsifiers are conventional anionic, but preferably nonionic, emulsifiers which lead to oil-in-water emulsions.
• the alkali metal, ammonium, amine and alkaline earth metal salts of long-chain alkyl sulfates, sulfonates and phosphoric acid partial esters are suitable as anionic emulsifiers.
• Particularly suitable are the salts of sulfuric acid semiesters or phosphoric acid partial esters of linear alcohols or oxo alcohols each having 12 to 18 carbon atoms or the polyglycomonoalkyl ethers having 12 to 18 carbon atoms in the alkyl group and the olefin sulfonates, ester sulfonates and alkanesulfonates containing 12 to 20 carbon atoms, the alkylbenzenesulfonates with 6 to 16 carbon atoms in the alkyl groups, the sulfonates of the polyglycol monoalkyl ethers with 12 to 18 carbon atoms in the alkyl groups and the salts of the fatty acids with 12 to 18 carbon atoms.
• anionic emulsifiers fatty acid amine salts, in particular salts of alkanolamines or alkanolalkylamines having 2 to 7 carbon atoms, are preferably used.
• Suitable nonionic emulsifiers include, for example, the sorbitan esters of higher fatty acids and the alkyleneoxy adducts with higher linear mono- and polyhydric alcohols, alkylphenols, long-chain carboxylic acids, carboxamides and hydroxy fatty acids with 10 to 24 carbon atoms and on fatty acid glycerol or sorbitan esters.
• the adducts of 5 to 40 mol of ethylene oxide with long-chain, in particular primary alcohols with 12 to 18 carbon atoms and with fatty acid sorbitan esters are preferably used as nonionic emulsifiers.
• the adducts of 5 to 20 mol EO of fatty acid sorbitan esters are particularly preferred.
• the proportion of emulsifiers in the total emulsion is generally 0.05 to 2% by weight, preferably 0.1 to 0.8% by weight and in particular 0.15 to 0.4% by weight, regardless of whether a single emulsifier or a mixture of several emulsifiers is used.
• the polyacrylic acid contained in the agents serves on the one hand as a consistency agent, but on the other hand also as a suspending agent and is responsible for the fact that the agents can be polished easily and without residue after drying.
• Polyacrylic acids with average molecular weights between 0.8 ⁇ 106 and 5 ⁇ 106, preferably 1 ⁇ 106 to 4 ⁇ 106, are suitable.
• the polymer is preferably used in the acidic form in the preparation of the compositions, but is generally present in the finished compositions in a partially neutralized form.
• the proportion of polyacrylic acid in the compositions is 0.1 to 3% by weight, preferably 0.3 to 1.5% by weight and in particular 0.4 to 0.8% by weight.
• the task of the alkalizing agents is to give the finished glass cleaning agent, in interaction with the acids contained, a neutral to slightly alkaline pH, preferably between 7.5 and 9.5.
• Alkali metal salts, ammonia and alkanolamines and alkanolalkylamines having 2 to 7 carbon atoms, for example, are suitable.
• the amount of Alkalizing agents depend primarily on the amount of polyacrylic acid contained in the agents. Usually no more than 2% by weight, preferably between 0.05 and 1% by weight, of alkalizing agents is used.
• the agents according to the invention can contain up to 3% by weight, preferably not more than 1% by weight, of conventional auxiliaries and additives.
• auxiliaries and additives examples are perfume, preservatives, salts and dyes.
• a particularly preferred composition of the glass cleaning agent has the following composition: 4 - 12% by weight of de-aromatized gasoline and / or isoparaffin with boiling ranges from 140 to 180 ° C, 15-25% by weight of microcrystalline calcium carbonate with a particle size of 98% by weight below 100 ⁇ m, 0.7 - 1.3% by weight silicone oil with a viscosity of 50 to 150 mPas, 0.15-0.4% by weight adduct of fatty acid sorbitan ester and 5 to 20 moles of ethylene oxide, 0.4-0.8% by weight polyacrylic acid with average molecular weight between 1 ⁇ 106 and 4 ⁇ 106, 0.05-1% by weight alkali hydroxide and ad 100 wt .-% water.
• the procedure is generally such that water, emulsifier and, if appropriate, other auxiliaries are initially introduced and then the polyacrylic acid is added with vigorous stirring. After swelling of the polyacrylic acid, the desired pH is adjusted with alkalizing agent and the calcium carbonate is then stirred in. Finally, a mixture of organic solvents, silicone oil and optionally perfume is emulsified into the aqueous phase.
• the preparation of the agent can also be varied in such a way that the polyacrylic acid solution is first strongly alkalized before the calcium carbonate is stirred in and only then adjusted to the desired pH by adding acid. The viscosity can be determined with a Brookfield viscometer using the spindle 6 at 20 revolutions per minute.
• the finished paste-like agent can be filled in cans, tubes or dispensers made of different materials.
• the agent is used in such a way that the product is preferably spread over a large area on the surface to be cleaned, with the aid of a damp cloth or damp sponge.
• the applied agent is allowed to dry and then the remaining residues are removed, for example by rubbing with a cloth, a fleece or with paper.
• the agents are equally suitable for cleaning surfaces made of glass, shiny ceramics or enamel. However, the advantages of the agents have a particularly clear effect when cleaning windows or mirrors.
• the resulting dispersion was mixed with a mixture of 23 kg isoparaffin (boiling range 155 to 173 ° C), 4.6 kg silicone oil (Baysilon M 100) and 0.23 kg perfume oil, resulting in a stable paste-like emulsion. It had a pH of 8.1 and a viscosity of 20,000 mPas at 20 ° C (measured with a Brookfield viscometer, spindle 6, at 20 revolutions per minute).
• the percentage composition of the mass was:
• the product was packed in aluminum tubes for sale.
• a detergent exhibited similarly good cleaning properties and, with an otherwise identical structure, contained a ground natural calcium carbonate with an average particle size of 2.8 ⁇ m (99.9% by weight below 10 ⁇ m).
