Definitions

• the invention relates to a cleaning agent, in particular for textiles.
• the detergents used for textiles today contain polyphosphates.
• large amounts of polyphosphates end up in rivers, which is now a serious environmental problem.
• Considerable efforts have therefore been made for a long time to find suitable substitutes for polyphosphates.
• a satisfactory result has not yet been achieved.
• the invention is therefore based on the object of creating a treatment agent, in particular for textiles, or of providing an additive for such treatment agents with the aim of reducing the polyphosphate content of the conventional treatment agents or even being able to dispense entirely with polyphosphates and other phosphorus compounds.
• the invention consists in the fact that the cleaning or treatment agent contains milk protein. It has surprisingly been found that milk protein (also called milk protein) is able due to its structure to take over the effect of the phosphates previously used in conjunction with other conventional treatment or cleaning agent components. In contrast to polyphosphates, milk protein is degradable, so there are no environmental problems. Milk protein is a by-product of milk utilization in large quantities, for which the invention also creates a use.
• milk protein also called milk protein
• Casein or caseinates are preferred. Casein has long been known as an additive for soaps, so it is pointed out in "Ullmann, Encyclopedia of Technical Chemistry", Volume 3, 1916, pages 292 to 297, in particular on page 297, that toilet soap is increased by adding 10% casein solution and can be improved in quality. The soap should become more delicate and durable and have greater foaming power. Furthermore, in the case of a dishwashing detergent which is intended in particular for manual dishwashing, it is known to use casein in an amount of 0.25 to 5 percent by weight.
• the milk protein is normally present in the dry matter of a detergent in amounts of more than 5 to 20 percent by weight, in particular 7 to 15 percent by weight. In special cases, however, the proportion may also be higher, especially if the detergent is otherwise only the main components normally used, such as surfactants and the like. Like. Contains. It has proven to be advantageous if the detergent additionally contains at least one softening agent, with phosphate-free softening agents being preferred. Such hardeners are, for example, sodium aluminum silicates, such as zeolites, and complexing agents, such as ethylenediaminetetraacetic acid, nitriloacetic acids and the like. Such softening agents or chelating agents are preferably contained in the detergent according to the invention, because this has the full effect of casein as a substitute for tripolyphosphate.
• milk protein especially casein
• casein is usually commercially available as a powder that is sparingly soluble in water.
• casein can be made soluble in a known manner. Solubilization using ammonium hydroxide is preferred.
• other soluble caseinates can also be used.
• the detergent according to the invention normally contains 5 to 20 percent by weight alkylbenzenesulfonate, 20 to 35 percent by weight sodium percarbonate and / or sodium perborate, 3 to 15 percent by weight alkali silicate and 5 to 30 percent by weight Casein, an addition of 5 to 15 percent by weight of at least one softening agent being preferred.
• the detergent according to the invention can contain other conventional constituents, such as cellulose derivatives, fatty alcohol oxyethylates, sodium sulfate and further additional washing aids, such as sodium soaps as foam suppressants.
• the cleaning or treatment agent is preferably free of phosphorus compounds.
• the cleaning agent according to the invention is particularly suitable as a detergent for textiles and in turn as a detergent which can be used both at 60 ° and at 90 ° C laundry. All that is required is a main wash cycle. H. there is no need for a pre-wash and a soft wash. This is due to the special dirt-dissolving and dirt-carrying properties of the milk protein. Furthermore, sodium sulfate can be dispensed with as an additive in the detergent, which further reduces the salt load in the waste water.
• the detergent is suitable for use in washing machines and not only in the household, but also for large laundries, hospitals and the like. The like. It shows no dirt reduction position.
• the cleaning agent according to the invention can also be used in other fields, for example as a textile auxiliary or as an additive, for example.
• B. for washing or cleaning textile goods before dyeing, during dyeing and after dyeing.
• the milk protein is particularly valuable in its use when leveling stained goods. It has been shown that stains and other discoloration can be removed in a washing process with the help of the cleaning agent according to the invention even where there are all commercially available chemicals, such as.
• the cleaning agent according to the invention is also suitable for cleaning heavily soiled objects, such as machines, apparatus; Boats, ships and aircraft bodies, swimming pools, it is preferably used as part of a high pressure cleaning.
• the special abilities of milk proteins to remove coarse dirt come into play here. It is therefore not necessary for the heavy soiling to be completely dissolved. It is sufficient to remove the dirt in the form of more or less coarse particles.
• the cleaning agent according to the invention is to be used as a detergent for textiles, then it is normally in a dry form, e.g. B. as a free-flowing powder.
• detergent amounts of, for example, 200 g are sufficient for a washing process in comparison to the otherwise usual 250 g, which are required for known detergents for prewash and main wash.
• the lower weight quantity alone reduces the pollution of the waste water.
• there is the good biodegradability of the milk proteins. Saving a pre-wash and a soft wash also saves water and energy. Due to the good dirt-bearing properties of the milk proteins, both a good detachment of the dirt and a softening of the textile fibers are achieved.
• the tear strength of the textiles is not reduced by the detergent according to the invention.
• the cleaning agent according to the invention can also be in liquid form, which is preferred if further constituents of the cleaning agent are usually used in liquid form anyway. This is special when used as a textile aid. If the cleaning agent is in liquid form, it expediently also contains a preservative in order to avoid bacterial decomposition of the milk protein.
• TPP pentasodium triphosphate
• a detergent suitable for washing at 60 ° C has the following composition:
• the advantage of the invention is particularly clear, since the heavy-duty detergents in particular - especially for use at 60 ° C. - normally have a very high phosphate content.
• This example shows further compositions of phosphate-free detergents.
• Examples 5 to 10 below show the use of milk proteins in the form of liquid preparations of digested milk protein which contain preservatives. These liquid preparations are preferably used in combination with surfactants or surfactant mixtures. When used as a dyeing aid, the solution of the milk protein can be called an equalizer and the solution of the surfactants can be called a corrector.
• the equalizer can be used on its own in the textile industry, e.g. B. as a leveling agent.
• the leveler milk protein
• the ratio of leveler to corrector can be in the ratio of 1: 2 to 2: 1, preferably 1: 1.
• the leveler preferably contains 5 to 20 percent by weight soluble milk protein (caseinates) and a sufficient amount of preservative.
• the corrector usually contains 20 to 60 percent by weight of wetting agent and water-soluble organic solvents.
• the leveler and corrector are preferably prepared and used in the form of a common liquid mixture.
• this may contain about 10 to 30 percent by weight casein or caseinate and about 90 to 70 percent by weight surfactant mixture. Depending on the intended use, this liquid mixture is then diluted many times over.
• the corrector is mainly used for stained, reactive and direct stains on cellulose goods with the possibility of refinishing in the decoction bath, as well as for lightening too dark reactive stains on cellulose, furthermore for removing oligomers in polyester stains, as detergent for removing incrustations (from tar , oil etc.), for containers, foulards, stenter frames, screens, machines and machine parts, air conditioning systems as well as vehicle and aircraft bodies.
• the mixture of leveler and corrector is diluted, preferably in a ratio of 1: 3 to 1: 5. This lowers its viscosity so that it can be added to the heated water of the high-pressure cleaner.
• a detergent is also suitable for cleaning by boiling, which can be combined with high-pressure cleaning for stubborn soiling.
• milk protein is used as a leveling agent for cotton dyeing, especially of knitted cotton fabrics using substantive and reactive dyes after the pull-out process.
• the leveling agent is added to the dye liquor prophylactically to prevent color irregularity.
• liquid leveler per liter of liquor 0.05 to 0.35 g casein per liter of liquor
• Equalizer and corrector which preferably consists of a mixture of non-ionic emulsifiers, detergents and cleaning enhancers, in combination remove color stains and dirt stains from cotton stains that cannot otherwise be cleaned if they have been dyed with substantive and reactive dyes.
• the coloring remains unimportant.
• the color tone becomes a maximum of 10% lighter.
• Color nuance using milk protein and a surfactant mixture in a hot dye bath Color nuance using milk protein and a surfactant mixture in a hot dye bath.
• the special leveling and cleaning effect is due to the milk protein, especially casein and caseinate.
• the other chemicals or the corrector have a supporting effect.
• the remaining components of the detergent or the corrector can be replaced by equivalent substances.
• leveler and corrector are also effective for high-pressure cleaning of food businesses, public and private swimming pools, sewage treatment plants and containers.
• the viscous mixture of corrector and leveler is first diluted 3 to 5 times. About 20 to 60 l of this solution are then metered into 3000 to 5000 l of heated washing water. The leveler and corrector are then approximately 150 to 1250 times diluted (0.08 to 1.3 g / 1 washing liquid).
• this high-pressure cleaning agent was also able to remove sticky and hardened impurities with great success.
