Definitions
- the invention relates to a detergent additive based on swellable layered silicates.
- Maschös ⁇ means for KeiSgrad reinforcement.g are known. These contain optical brighteners and non-swellable layered silicates, e.g. approx. natural mineral magadiite.
- D ⁇ -A-35 25 405 discloses the use of aluminum silicates with limited swellability in laundry detergents, which also contain optical brighteners.
- REPLACEMENT BLA ⁇ (RULE 26) trated detergents with a high bulk density consists in the omission of fillers or so-called adjusting agents, such as sodium sulfate.
- DE-C-3 424 987 describes the production of detergent concentrates with a high bulk density, which do not contain sodium sulfate as an adjusting agent.
- a basic powder is produced by spray drying, which contains the usual detergent ingredients such as surfactants, carboxymethyl cellulose (CMC), sodium polyphosphate, zeolite A, water glass, optical brighteners, etc. contains.
- the base powder obtained which has a low bulk density and is free of sodium sulfate, is sprayed with other nonionic surfactant to increase the bulk density and dry-mixed with a separately produced granulate with a high bulk density.
- the optical brightener is exposed to contact, especially oxidation, by other detergent components.
- a problem is the incorporation of optical brighteners in detergent concentrates with a high bulk density.
- the optical brightener was either processed in the spray product or was subsequently added to the tower product as a powder (Spray product) mixed. If the optical brightener is not separated from the bleaching agents, such as sodium perborate, but especially sodium percarbonate, which are also contained in the detergent, by a coating (coating) produced in the production or by the presence of diluting, spatially separating and water-adsorbing adjusting agents, optical ones can be used Brighteners are oxidized. The bleaching potential consumed in this way is therefore no longer available for the subsequent bleaching action in the wash liquor.
- the oxidation product of the optical brightener can be colored yellow, as a result of which the detergent shows a yellow tinge on the one hand, and on the other hand draws the yellow oxidation product of the brightener noun onto the washing textiles, which leads to an impairment of the aesthetic aspect, especially in the case of white laundry .
- the detergent agglomerates of high bulk density generally have poor dispersibility; this can be improved by adding dispersants and disintegrants which swell in contact with water and blow up or loosen the agglomerates, which leads to improved solubility and availability of the active components.
- dispersants and disintegrants which swell in contact with water and blow up or loosen the agglomerates, which leads to improved solubility and availability of the active components.
- Brightener spotting is the result of prolonged contact of undissolved, brightener-containing agglomerate with the laundry. Due to the direct contact of locally over-concentrated optical brightener, this is transferred to the tissue in a locally limited manner at the contact point in undesired, high concentrations. This is particularly visible in the presence of UV light in the form of slight stains and represents an impairment of the aesthetic aspect.
- the detergent agglomerates should therefore contain disintegrants so that they are blasted in contact with the wash liquor, as a result of which the optical brightener is homogeneous dissolved in the wash liquor and direct contact of the detergent agglomerates with the laundry is avoided.
- the object of the invention was to provide a detergent additive in agglomerate form (granulate form) which contains at least one swellable layered silicate and an optical brightener which, with good mechanical stability, disintegrates well in water and in which the optical brightener is present in a homogeneous distribution and against Oxidation is protected by the oxidizing agent contained in the detergent.
- the invention relates to a detergent additive in agglomerate form, which is characterized in that it contains at least one swellable layered silicate and at least one optical brightener in intimate contact with one another.
- the optical brightener Due to the close contact of the optical brightener with the layered silicate, the latter is reliably removed from the oxidation processes during the storage of the detergent, and the "brightener spotting" on the laundry is avoided when the detergent is used. It is believed that the optical brightener is at least partially embedded between the layers of the layered silicate, since the discrete ones initially present Brightener particles in the detergent additive have largely disappeared and the layered silicate particles appear homogeneously colored by the brightener in the fluorescence microscope.
- the weight ratio of swellable layered silicate (s): optical brightener is preferably about 200-7: 1, in particular 100-10: 1.
- the swellable layered silicate is preferably a natural or clay mineral.
- the swellable clay mineral is preferably montmorillonite, beidellite, saponite or hectorite.
- the montmorillonite can be used in the sodium or calcium form or in the form of a calcium montmorillonite ion-exchanged with soda. Synthetically produced clay minerals from the group mentioned above can also be used.
- the layered silicate is preferably used in an amount of 90 to 99% by weight.
- the swellable layered silicates have the property of intercalating polar agents between the silicate lamellae under internal crystalline swelling, which is noticeable at higher concentrations in an increase in the layer spacing.
- the optical brightener is preferably a stilbene derivative.
- benzoxazole, coumarin and pyrazoline derivatives can also be used. These products generally have an anionic dye residue, which is why it was surprising that they are embedded between the negatively charged layers of the swellable layered silicate.
- Suitable optical brighteners are, for example
- Cyanuric acid chloride diaminostilbene (a) Cyanuric acid chloride diaminostilbene (CCDAS), in which R can have the following meanings:
- the agglomerate particles of the detergent additive are preferably coated with synthetic zeolite or layered sodium silicate (preferably about 3 to 15% by weight) , whereby the whiteness of the agglomerate is improved.
- Further preferred alternatives for concealing the intrinsic color of the agglomerates consist of dyeing with dyes customary in detergents, in particular pigment dyes, for example Unidis ⁇ perse 0 blue B- ⁇ (commercial product from Ciba-Geigy) (preferably about 0.01 to 0.5 wt.%), or in the addition gefärb ⁇ ter active substances (preferably about 0.3 to 5 wt .-%), such as the photobleaching agent Tinolux ® BB 5 (commercial product of Ciba-Geigy).
- pigment dyes for example Unidis ⁇ perse 0 blue B- ⁇ (commercial product from Ciba-Geigy) (preferably about 0.01 to 0.5 wt.%), or in the addition gefärb ⁇ ter active substances (preferably about 0.3 to 5 wt .-%), such as the photobleaching agent Tinolux ® BB 5 (commercial product of Ciba-Geigy).
- the agglomerate preferably has a bulk density of more than about 700 g / liter and, owing to this high bulk density, is compatible with highly concentrated detergents at high density.
- the invention further relates to a process for the production of the detergent additive described above in agglomerate form, which is characterized in that the optical brightener (s) are added to the layered silicate (s) as an aqueous slurry.
- the layered silicate (s) can be, for example, in an intensive mixer, e.g. in an Eirich mixer.
- the optical brightener (s) (preferably as an aqueous dispersion) is then (are) sprayed with swirling into the powder component. This forms an agglomerate, which is sieved and coated by adding zeolite in powder form to improve the whiteness.
- the agglomerate obtained is readily dispersible in water.
- the optical brightener is protected against oxidation and is fully available after the agglomerate has dissolved in the wash liquor. Due to the presence of the layer silicate swellable in water, no "brightener spotting" occurs.
- the agglomerate can subsequently be mixed into the detergents produced in brightener-free production plants, so that the plants are not contaminated with brighteners.
- the invention furthermore relates to a detergent containing the detergent additive described above in addition to conventional detergent components such as anionic and nonionic surfactants, builders (builders), polymers (co-builders), graying inhibitors, bleaching agents and bleach activators, enzymes , Foam inhibitors, fragrances and / or dyes.
- conventional detergent components such as anionic and nonionic surfactants, builders (builders), polymers (co-builders), graying inhibitors, bleaching agents and bleach activators, enzymes , Foam inhibitors, fragrances and / or dyes.
- optical brightener or a mixture of various optical brighteners as an aqueous dispersion (slurry) is added to the powdery layered silicate with intensive swirling.
- the mixture agglomerates at a water content of about 20 to 30% by weight, based on the total mixture.
- an agglomerate is obtained which is dried in a suitable dryer, preferably in a fluid bed dryer, to a residual water content of about 2 to 15% by weight, preferably of about 5 to 10% by weight becomes.
- the agglomerate obtained is sieved using a sieving machine to a particle size of approximately 0.2 to 2.5 mm, preferably 0.5 to 1.7 mm.
- the fraction ⁇ 0.2 mm is returned to the agglomeration.
- the resulting coarse grain is crushed with a roller crusher and placed on the screening plant again.
- the sieved agglomerate is placed in a drum mixer (for example in a drum mixer from Telschig) or in a granulating plate. Then about 3 to 15% by weight, preferably about 5 to 10% by weight, of synthetic zeolite in fine-grained form are added.
- the average particle size of this powder should preferably be ⁇ 20 ⁇ m, in particular approximately 3 to 10 ⁇ m.
- the detergent additive produced according to the described method has the following additional advantages:
- the bulk density is greater than 700 g / liter, so that it is compatible with detergents with a high bulk density. Due to the swelling effect of the layer silicate contained in the detergent additive, the agglomerates quickly disintegrate in water. No brightener spotting is observed on the laundry. The optical brightener is fully available in the detergent. The agglomerate is mechanically stable. The agglomerate can be subsequently mixed into the detergent, so that essential parts of the detergent production system are not contaminated with optical brighteners.
- a detergent additive was produced according to the following recipe:
- Bentonite (Laundrosil ® DGA, Süd-Chemie AG) 98% by weight
- an equivalent amount of brightener 0.2 wt .-% Tinopal ® DMS-X hc, is introduced into an identical detergent via the slurry already in the preparation of Sprüh GmbHs.
- the loss in% was calculated from the brightener content determined before and after the storage test by means of HPLC analysis. The results are shown in Table I.
- the decrease in the brightener content due to oxidative degradation is significantly smaller when using the detergent additive according to Example 1 compared to a detergent of the same gross composition in which the brightener is contained in the spray product.
- a detergent additive was produced according to the following recipe:
- Bentonite (Laundrosil ® DGA, Süd-Chemie AG) 99% by weight
- B Optical brightener (Tinopal ® -CBS-X) 1% by weight
- the detergent additive was subjected to a spotting test on pre-lightened cotton fabric as described in Example 1.
- the evaluation is as follows:
- the breakdown of the brightener is less than in a detergent of the same gross composition in which the brightener is contained in the spray product.
