Definitions
- the invention relates to detergents for commercial use, the dirt-removing Polymer included.
- Detergents contain the ingredients that are essential for the washing process such as surfactants and builder materials usually other components that can be found under the
- washing aids can summarize and the different groups of active ingredients such as foam regulators, graying inhibitors, bleaches, bleach activators and color transfer inhibitors.
- Such auxiliary substances also include substances which give the laundry fiber dirt-repellent properties and which if present during the washing process, the dirt-removing ability of the others Support detergent ingredients. The same applies analogously to cleaning agents for hard surfaces.
- Such dirt-releasing substances are often called "Soil-release" active ingredients, or because of their ability, the treated surface to Example of the fiber to repel dirt, referred to as "soil repellents".
- German Offenlegungsschrift DT 16 17 141 describes a washing process using polyethylene terephthalate-polyoxyethylene glycol copolymers.
- the German patent application DT 22 00 911 relates to detergents, the nonionic surfactant and a Copolymers of polyoxyethylene glycol and polyethylene terephthalate included.
- In the German Offenlegungsschrift DT 22 53 063 contains acidic textile finishing agents, which is a copolymer of a dibasic carboxylic acid and an alkylene or cycloalkylene polyglycol and optionally contain an alkylene or cycloalkylene glycol.
- detergents contain 5 to 30% by weight of nonionic surfactants, 30 to 80 % By weight of builders for such surfactants, 1 to 20% by weight of water and 0.5 to 20% by weight of the aforementioned polymers.
- builder substances Polyphosphates, sodium carbonate, sodium bicarbonate, sodium silicate and their Mixtures in question.
- a 1% aqueous solution has one Detergent composition has a pH in the range of 9 to 11.5, for example from 9 to 10.5.
- water-soluble builder salts which have an alkaline reaction in an aqueous medium, hydrolysis of the aforesaid, which promote dirt washability Polymers at pH values of 8 and higher, e.g. in the range of 9 to 11, cause.
- the degradation or change in the polymers then increases with increasing pH value stronger, so that the polymers promote their soil release Lose properties.
- anionic surfactants can also promote such destabilization.
- European patent EP 066 944 relates to textile treatment agents which contain a copolyester of ethylene glycol, polyethylene glycol, aromatic dicarboxylic acid and sulfonated aromatic dicarboxylic acid in certain molar ratios.
- European or European patent EP 185 427 discloses methyl- or ethyl-terminated polyesters with ethylene and / or propylene terephthalate and polyethylene oxide terephthalate units and detergents which contain such a soil release polymer.
- European patent EP 241 984 relates to polyesters which, in addition to oxyethylene groups and terephthalic acid units, also contain substituted ethylene units and glycerol units.
- Polyesters are known from European patent EP 241 985, which contain, in addition to oxyethylene groups and terephthalic acid units, 1,2-propylene, 1,2-butylene and / or 3-methoxy-1,2-propylene groups and glycerol units and with C 1 - C 4 -alkyl groups are end group-capped.
- the European patent EP 253 567 relates to soil release polymers with a molecular weight of 900 to 9000 made of ethylene terephthalate and polyethylene oxide terephthalate, the polyethylene glycol units having molecular weights of 300 to 3000 and the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate 0.6 to Is 0.95.
- European patent application EP 272 033 discloses polyesters with poly-propylene terephthalate and polyoxyethylene terephthalate units end-capped by C 1-4 alkyl or acyl residues.
- European patent EP 274 907 describes sulfoethyl-end group-capped soil-containing polyester.
- European patent application EP 357 280 sulfonation of unsaturated end groups produces soil-release polyesters with terephthalate, alkylene glycol and poly-C 2-4 glycol units.
- German patent DE 28 57,292 discloses certain hydrophilic polyurethanes and copolyesters with recurring alkoyl terephthalate and polyalkoyl terephthalate units as well as their mixtures as anti-soiling detergent ingredients.
- the German patent DE 26 13 791 describes detergents which contain 0.1 to 3% by weight of dirt-releasing alkyl cellulose ethers, hydroxyalkyl cellulose ethers or hydroxyalkyl alkyl cellulose ethers.
- detergent for the Commercial area usually contain neither bleach nor bleach activator, because the bleaching or disinfection in the context of the commercial Washing process as a separate treatment step, usually in one of the last Zones before leaving the car wash.
- detergent formulations which contain the following components: (a) about 20 wt .-% of a C 8-22 -Alkylmonoethers a polyethylene glycol with about 5 to 20 alkylene oxide units, (b) about 60% sodium sesquicarbonate, (c) approx. 10% sodium silicate with a SiO 2 : Na 2 O ratio of approx. 2 to 3: 1, (d) approx. 0.1 to 2% of a hydroxybutylmethyl cellulose with a DS value of approx.
- the invention accordingly relates to a highly alkaline detergent contains nonionic surfactant and a pH in the range of 12 to 13 at a concentration of 1% by weight, which is characterized in that it is a soil release polymer contains.
- Suitable dirt-releasing polymers in the sense of the invention are in particular Copolyester from dicarboxylic acids, for example adipic acid, phthalic acid or Terephthalic acid, diols, for example ethylene glycol or propylene glycol, and polydiols, for example polyethylene glycol or polypropylene glycol, as well as nonionic Hydroxyalkyl cellulose ethers, for example hydroxypropyl cellulose.
- dicarboxylic acids for example adipic acid, phthalic acid or Terephthalic acid
- diols for example ethylene glycol or propylene glycol
- polydiols for example polyethylene glycol or polypropylene glycol
- nonionic Hydroxyalkyl cellulose ethers for example hydroxypropyl cellulose.
- Suitable dirt-releasing polyesters are known from the documents cited above and from the unpublished German patent applications DE 44 17 686 and 1 95 02 181.9 and are commercially available, for example, under the names Sokalan® from BASF or Velvetol® 251C from Rhône-Poulenc.
