- Color transfer inhibitors preferably used in detergents are soluble vinylpyrrolidone and vinylimidazole copolymers with molar masses above 25,000 and finely divided crosslinked polymers based on vinylimidazole.
- the powdered or granular detergents according to the invention can contain up to 60% by weight of inorganic adjusting agents. Sodium sulfate is usually used for this. However, the detergents according to the invention are preferably low in adjusting agents and contain only up to 20% by weight, particularly preferably only up to 8% by weight, of adjusting agents.
- the detergents according to the invention can have different bulk densities in the range from 300 to 1200, in particular 500 to 950 g / l.
- Modern compact detergents generally have high bulk densities and show a granular structure.
- agents which are used as additives to peroxide-containing or peroxide-free detergents are also suitable as the form of the described activators for textile washing. They essentially contain activator or a mixture of activator and per-compound and, if appropriate, further auxiliaries and additives, in particular stabilizers, pH-regulating agents, thickeners and surfactants.
- the present invention furthermore also relates to bleach additives for textile washing, which contain 1 to 30% by weight, preferably 5 to 25% by weight, based on the total amount of the additive preparation, of one or more compounds I ten.
- Typical bleach additives of this type have the following composition:
- peroxide stabilizers 0 to 5% by weight, preferably 0.1 to 3% by weight, of peroxide stabilizers
- the present invention also relates to dishwashing agents which contain 0.05 to 15% by weight, preferably 0.1 to 10% by weight, in particular 0.5 to 5% by weight, in each case based on the total amount of the preparation , one or more compounds I in addition to the usual constituents.
- agents intended for cleaning hard surfaces generally contain, in particular, surfactants, builders and, in the case of polishing and abrasive agents, abrasive components. Since these agents are often used at room temperature, the use of the activators according to the invention has a particularly advantageous effect on the bleaching and germicidal action.
- Disinfectants based on the activators described generally contain, in addition to these and inorganic per-compounds, further auxiliaries and additives, such as pH-regulating substances, stabilizers and surfactants. In special cases, they can additionally contain special microbicides which increase the very broad killing effect of the activated per-compound against certain germs.
- the present invention also relates to disinfectants which contain 1 to 40% by weight, preferably 5 to 30% by weight, based on the total amount of the preparation, of one or more compounds I.
- Typical disinfectants of this type have the following composition:
- peroxide stabilizers 0 to 5% by weight, preferably 0.1 to 3% by weight, of peroxide stabilizers
- the use of the activators described according to the invention is in no way limited to the use in a ready-made form of these described or other types.
- the focus is generally on the individual metering of reagents, since it is often the more cost-effective method.
- 0.2 mol of the oxime is placed in a round bottom flask and dissolved in 60 g of pyridine with stirring. At 20 to 30 ° C, 0.1 mol of the dicarboxylic acid chloride are added dropwise within 10 to 20 minutes. In the case of an exothermic reaction, cooling is necessary. After 2 hours of stirring at room temperature, the reaction mixture is introduced into 800 ml of water and extracted three times with 200 ml of methyl tert-butyl ether each time. The combined organic phases are washed with water, dried over sodium sulfate, filtered and freed from the solvent. example 1
- the title compound was prepared from acetone oxime and isophthalic acid dichloride according to the general preparation instructions above in a yield of 80% as a white solid with a purity of 95%.
- the title compound was prepared from acetone oxime and adipic acid dichloride according to the general preparation instructions above in a yield of 96% as a white solid with a purity of 95%.
- the title compound was prepared from acetone oxime and terephthalic acid dichloride according to the general preparation instructions above in a (non-optimized) yield of 18% as a bright solid with a purity of 90%.
- Soil-Release-Polymer I graft polymer of vinyl acetate on polyethylene glycol of molecular weight 6000, molecular weight of graft polymer 24000
- Soil-Release-Polymer II polyethylene terephthalate / polyoxyethylene terephthalate with a molecular weight of 8000
- the color strength of the test fabric was measured photometrically. From the reflectance values measured at the individual test tissues at 18 wavelengths in the range from 400 to 700 nm at a distance of 20 nm, the ver. Described in A. Kud, Seifen, ⁇ le, Fette, Wwachs 119, pp. 590 - 594 (1993) ⁇ the respective color strengths of the test soils are determined before and after washing and the absolute bleaching action A abS is calculated in% therefrom.
- Isophthaloyl bisacetonoxim (Example 1) was tested halts-dishwashing detergents of the following composition for the removal of tea stains as bleach activator component in a domestic ⁇ Q:
- isophthaloyl-bisacetone oxime and, for comparison, TAED were used as the bleach activator.
- the cleaning result was assessed visually according to a cleaning cycle, the rating "0" meaning that no more deposits can be seen and the rating of "5" means that the tea deposit is still completely present.
