Definitions

the application relates to storage-stable detergents which, in addition to at least one peracid or its salts, contain at least one specific optical brightener of the bis-benzofuranyl type, and to their preparation and use for washing textiles.
M in formula (I) is, for example, alkaline earth metal such as magnesium or calcium, but preferably alkali metal such as lithium, sodium, potassium and optionally substituted ammonium such as ammonium, mono-, di- or triethanol-ammonium, mono-, di- or tripropanol -ammonium or tri- or tetramethyl-ammonium.
alkaline earth metal such as magnesium or calcium
alkali metal such as lithium, sodium, potassium
ammonium such as ammonium, mono-, di- or triethanol-ammonium, mono-, di- or tripropanol -ammonium or tri- or tetramethyl-ammonium.
the detergents contain brighteners of the formula
optical brighteners of the formula I and II are known and can be prepared by known methods (DE-OS-2 238 734).
the peracids or their salts are organic or inorganic compounds described in the literature or on the market which bleach textiles even at temperatures from 20 ° C. Diperoxydodecanedioic acid (DPDDA) is of interest as organic peracid.
the amount of organic peracid to be used is preferably 0.5% to 10%, in particular 1% to 5%.
very effective, inorganic peracids such as persulfate and / or percarbonate can also be used.
the amount of inorganic peracids is preferably 1% to 30%, in particular 10% to 20%, based on the total weight of the detergent and optionally and advantageously in combination with small amounts of catalytic bivalent metal salts, as described in US Pat. No. 4,655,782 and U.S. 4,655,953.
Metal salts of copper and / or manganese are preferably used.
the peracids are mainly added to the detergent by mixing the components e.g. with the help of screw dosing systems and / or fluidized bed mixers.
the detergents are dry detergents of conventional compositions.
they contain, for example, anionic, nonionic, amphoteric and / or cationic surfactants, builders such as, for example, pentasodium tripolyphosphate or substitute products such as phosphonates, polycarboxylates, acrylic-maleic copolymers, zeolites, nitrilotriacetate, Ethylene diaminotetraacetic acid, soil suspending agents such as sodium carboxymethyl cellulose, salts for adjusting the pH such as alkali or alkaline earth silicates, foam regulators such as soap, salts for adjusting the spray drying and granulate properties such as sodium sulfate, perfumes, and optionally antistatic and softening agents , Enzymes, photobleaches, pigments and / or shading agents.
these components should be stable with respect to the bleaching system used.
a granulate A is produced by drying and granulating a slurry consisting of approx. 1 part water and 1 part detergent of the following composition: 84 g Linear dodecylbenzenesulfonate 31 g Tallow alcohol-tetradecane-ethylene glycol ether (14 AeO) 37 g Na soap (mainly from behenic acid and C14-C20) 458 g Na tripolyphosphate 79 g Na silicate 20 g Mg silicate 12 g Carboxymethyl cellulose 2 g Ethylenediamine tetraacetate 222 g Na sulfate 1 g optical brighteners (FWA) according to the formula (I) - (II).
FWA optical brighteners
the peracid B (15 g DPDDA) is homogeneously mixed into 500 g of this granulate A, which has a residual moisture of ⁇ 5% after drying.
Samples of the detergent W thus obtained are: - On the one hand to check the initial value, immediately determined by extraction and spectrophotometric extinction measurement for the FWA content, (theoretically: 0.1% FWA based on the weight of the granulate A) - On the other hand stored in commercial washing powder-compatible cardboard packages, ie with a coating, under selected and controlled temperature and humidity conditions for certain periods of time. After storage, the FWA content of each detergent is determined immediately. The difference from the initial value, expressed as a percentage, is a measure of the stability of the FWA against the corresponding bleach in the washing powder.
the FWA determination mentioned above is carried out as follows: The washing powder is homogenized well by grinding and 1 g of it is mixed with 200 ml of solvent consisting of 9 parts of dimethyl sulfoxide and 1 part of water and stirred at room temperature for 30 minutes. Then it is centrifuged for 30 minutes. From the clear solution thus obtained, a sample is transferred with a pipette into a 1 cm quartz cuvette and its absorbance in the UV range, at the absorption maximum against a standard solution from the respective FWA measure up. The extinction is proportional to the FWA concentration. The reproducibility of the results is approx. ⁇ 1% if the test conditions are observed exactly the same.
the percentage FWA loss is determined according to the conditions described above. Storage is in a closed package, at 20 to 25 ° C. After 6 months the FWA loss is:
