Description

Antisoiling detergent with certain surfactant

The invention relates to keep ent from Ethersulfat- type and certain non-ionic surfactant of the alkyl polyethoxylate type washing and cleaning agents, soil-release polymer and a combination of certain anionic surfactant.

Detergents contain in addition to the indispensable for the washing process In¬ substances contained as surfactants and builders usually constituents more Be¬ that can be summarized under the term washing assistants and so different active substance groups such as foam regulators, supply grauungsinhibitoren, bleaches, bleach activators and Farbübertra- supply inhibitors include. Such auxiliaries also include punch Sub¬ which lend the fibers soil-repellent properties and, if present during the washing process, the Schmutzablösever¬ like support of the conventional ingredients. The same applies mutatis mutandis to cleaning agents for hard surfaces. Such soil-release substances are often materials as "soil release" -Wirk- or because of their ability, for example, fiber, dirt repellent equip the treated surface, referred to as "soil repellents." Because of their chemical similarity to polyester fibers, particularly effective soil release agents, but who can show the desired effect even in tissues of other material are copolyesters which dicarboxylic acid units, alkylene glycol units and contain Polyalkylenglykoleinhei- th. Soil-release copolyesters of the type mentioned and their use in detergents have been known for a long time. For example, the German Offenlegungsschrift DT 16 17 14 describes a washing process using polyethylene terephthalate-polyoxyethylene glycol copolymers. The German-OS 22 00911 be true detergents, nonionic surfactant and a copolymer of polyoxyethylene glycol and polyethylene terephthalate included. In the German DT open legungsschrift 22 53063 are mentioned which contain a copolymer of a dibasic carboxylic acid and an alkylene ode cycloalkylene and optionally an alkylene or cyclo alkylene acidic textile finishes. Polymers with molecular weight of 15,000 to 50,000 au ethylene terephthalate and polyethylene terephthalate, wherein having the polyethylene glycol units have molecular weights of 1000 to 10000 and since the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate is 2 to 6: 1, according to the German Offenlegungsschrif DE 3324258 in detergents are used. The European Paten EP 066 944 relates to textile treatment agents that keep a copolyester au ethylene glycol, polyethylene glycol, aromatic dicarboxylic acid and sul fonierter aromatic dicarboxylic acid in certain molar ratios ent. From the European patent EP 185 427 are methyl ode ethyl-capped polyesters with ethylene and / or propylene terephthalate and polyethylene oxide terephthalate units and washing itle, such a soil-release-poly he contain known. The European patent EP 241 984 relates to a polyester in addition to oxyethylene groups and terephthalic acid also contains substituted ethylene units and glycerol units. Polyesters are known from European Patent EP 241 985, in addition to oxyethylene groups and units Terephthalsäureein- 1,2-propylene, 1,2-butylene and / or 3-methoxy-l, 2-propylene groups and glycerol units and C \ - C4 ~ alkyl final group are sealed. The European patent EP 253 567 be¬ meets soil release polymers having a molecular weight of 900-9000 of ethylene terephthalate and polyethylene oxide terephthalate in which the polyethylene glycol units have molecular weights have from 300 to 3000 and the ratio of ethylene terephthalate to polyethylene Mol¬ terephthalate is 0.6 to 0.95. From the European patent application EP 272,033 least in part by Cι_4 alkyl or acyl groups end-capped polyesters with polypropylene terephthalate and Polyoxyethylenterephthalat-- zumin¬ units are known. The European patent EP 274907 describes sulfoethyl-terminally capped terephthalate-containing soil-release polyesters. In the European patent application EP 357280, soil-release polyesters containing terephthalate, alkylene glycol and poly-C2-4-glycol units are produced by sulfonation of unsaturated terminal groups. comprise polymers of ethylene terephthalate and polyethylene terephthalate, in de¬ the polyethylene glycol units have molecular weights from 750 to 5000 nen and the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate is 50:50 to 90:10 te¬, and their use in detergents is in the German patent DE described 2,857,292th that with use of low-ethoxylated sulfates or not compared to other surfactants only significantly less pronounced effect occurs (hereinafter referred to as ether sulfates), an additional Reinigungs¬ by the polymer in this Doku¬ ment is shown. As individual substances but these ether sulfates have good washing performance, they are therefore particularly interesting.

Against the background of this extensive prior art, the Applicant had the object of the cleaning performance of Waschmit¬ stuffs to further improve by the interaction of such soil release polymers Direction with surfactants of the ether sulfate type.

This object is substantially achieved by the presence of a surfactant combination of ether sulfates with low average degrees of ethoxylation and Alkyloligoethoxylaten having average degrees of ethoxylation in the range of 6.5 to 8.5.

The invention accordingly provides a detergent or cleaning agent, the iontensid an active ingredient combination of soil release polyester, purchase from ether sulfate type according to the general formula

Examples

Example 1: Preparation hvdroxyloruppenterminierter soil release Polvester

In a heated reaction vessel with a stirrer were 12.8 kg terephthalic acid, 19.1 kg of ethylene glycol and 0.1 kg of acid catalyst (Swedcat (R) 3) was heated under N2 at 200 ° C and are deposited as long as water until a clear melt originated (duration about 3 hours). Subsequently, the poly (ethylene terephthalate) thus obtained without workup was partially interesterified with polyethylene glycol. To this was added 85.0 kg of polyethylene glycol (mitt¬ Leres molecular weight 3000) and 0.1 kg of acid catalyst (Swedcat (R) 5) zuge¬ sets, vacuum (17 mbar) was applied and wur¬ by heating at 220 ° C to 14 continuously deposited 4 kg ethylene glycol. The product (SP1) had an OH number of 23 and a softening point ranging from 50 ° C to 60 ° C.
