Definitions
- the present invention relates to colored cleaning agents which are used for cleaning dishes in dishwashers.
- the invention relates to the use of certain dyes to color machine dishwashing detergents.
- the agents have to be colored in a contrasting manner, the dye must not stain the dishwasher or the dishes to be cleaned, even after long use of the same agent.
- the dyes must therefore not have a pronounced substantivity towards metal or plastic surfaces. It is also necessary that the dyes are completely removed from the dishwasher in the rinse cycle and that no film or colored lime stains are left on the dishes or in the machine when the water runs off. Since the wash ware will later be used for the preparation and storage of food, the dyes must continue to be completely toxicologically safe.
- the currently in the market Chen agents are colored with predominantly water-soluble dyes, which only partially solve the problems mentioned.
- the dyes should be able to be used regardless of the physical state of the cleaning agent and be chemically stable, so that neither decomposition of sensitive further ingredients nor discoloration or discoloration of the dyes occurs. Staining of machine parts or wash ware should be avoided as well as the formation of residues or deposits in the dishwasher.
- the invention relates to the use of dyes from the Ponceau 4R group (CAS No. 2611-82-7, Cl 16255), Allura Red 40 (CAS No. 25956-17-6, Cl 16035), aluminum red RLW ( Cl Mordant Red 83), Supranol ® Red GW (CAS No. 61901-44-8), Basantol ® Red 310 (CAS No. 61951-36-8), Basacid ® Green 970 (CAS No. 19381-50 -1), Supranol ® Green 6 GW (anthraquinone dye preparation with Acid Green 81), Supranol ® Green BW (anthraquinone dye preparation with Acid Green 84), Ultramarine Blue-6394 (CAS No. 57455-37 -5, Cl 77007), Acid Yellow 17 (CAS No. 6359-98-4, Cl 18965), Acid Yellow 23 (CAS No. 1934-21-0, Cl 19140) for coloring solid or liquid machine dishwashing detergents .
- Ponceau 4R is a red dye that is chemically called 7-hydroxy-8 - [(4-sulfo-l-naphthalenyl) azo] -l, 3-naphthalenedisulfonic acid trisodium salt. Ponceau 4R is approved as a food additive (E 124) in the European Union.
- Ponceau 4R is available in various trade names under which Ponceau 4R is available.
- Food-Red-7 Acid Red 18, Cochenillerot A or Brilliant Scarlet.
- the following formula shows the sulfonic acid, the trisodium salt of which is commercially available as Ponceau 4R:
- Ponceau 4R is indexed in Chemical Abstracts (CAS No. 2611-82-7) and listed in the Color Index under the number Cl 16255.
- This dye is an example of the fact that the suitability or unsuitability for dyeing automatic dishwashing detergents is an isolated phenomenon.
- the amaranth isomeric to this dye, a 3-hydroxy-4 - [(4-sulfo-l-naphthalenyl) azo] -2,7-naphthalenedisulfonic acid, color index number 16185, CAS no. 915-67-3, which differs from the Ponceau 4R only in the position of a -SO 3 -Na- group, discolors when the dishwasher detergent stained with it is discolored.
- Allura Red 40 is also a red dye and is chemically exactly called 6-hydroxy-5 - [(2-methoxy-5-methyl-4-sulfophenyl) azo] -2-naphthalenesulfonic acid disodium salt and is represented as the free acid by the following formula :
- Allura Red 40 is also approved as a food additive in the EU (E 129) and is sometimes called Curry-Red, Food-Red-17 or FD&C Red No. Designated 40.
- the dye is recorded in both CAS (CAS No. 25956-17-6) and the Color Index (Cl 16035).
- the aluminum red RLW (reference source Clariant GmbH) can also be used as the red dye, which is an azo dye preparation which is classified in the Color Index under the name Mordant Red 83.
- Another suitable in the present invention is the dye Supranol ® Red GW, which is listed in the Color Index under the name Acid Red-276th Another trade name for this dye, which is listed in CAS under number 61901-44-8, is Mitsui Acid Milling Red FG.
- Basantol ® Red 310 (CI name Acid Red 357), which is listed in CAS under number 61951-36-8, is also suitable as the red dye.
- Other trade names for this dye are Gryfalan Scarlet GL and Luganil Red GL.
- Green dyes that can be used in the context of the present invention are Basacid ® Green 970, Supranol ® Green 6 GW and Supranol ® Green BW.
- Basacid ® Green 970 is chemically exactly the trisodium salt of tris [5,6-dihydro-5- (hydroxyimino- ⁇ -N) -6- oxo- ⁇ -O) -2-naphthalenesulfonato ferrate (III), which is indicated in the CAS under the number 19381-50-1.
- Other trade names of this dye are Acid Green 1, Japan Green 401 and Naphthol Green. This dye can be found in the Color Index under the number Cl 10020 and is represented by the following formula:
- Supranol ® Green 6 GW contains Cl Acid Green 81 as a color component
- Supranol ® Green BW contains Cl Acid Green 84. Both dyes are available from DyStar Textilmaschinemaschine (formerly Bayer).
- Ultramarine blue-6394 (synonym: pigment blue 29) can be used as blue dye in the context of the present invention. This substance is listed in both Chemical Abstracts (CAS No. 57455-37-5) and in the Color Index (Cl 77007). In contrast to all other dyes which can be used in the frame of the present invention, this is a pigment which is not water-soluble but can only be dispersed. Although pigments are not usually used as dyes for machine dishwashing medium suitably, since they migrate into plastics at the elevated temperatures in the machine and permanently stain them, this blue pigment surprisingly does not have these negative properties.
- Acid Yellow 17 is the trisodium salt of [5-hydroxy-l- (2,5-dichloro-4-sulfophenyl) -3-methyl-4- (4 -sulfophenylazo) -lH-pyrazole and is indicated both in Chemical Abstracts (CAS No. 6359-98-4) and in the Color Index (Cl 18965) and is also available under the synonym Food-Yellow-5. Acid Yellow 17 is represented by the following formula:
- Acid Yellow 23 is chemically exactly the trisodium salt of [5-hydroxy-l- (4-sulfophenyl) -4- (4-sulfophenylazo) -lH-pyrazole-3-carboxylic acid and is represented by the following formula:
- the machine dishwashing detergents can be colored in various ways using the dyes mentioned above.
- the dyes can be incorporated into the entire composition as an aqueous solution or dispersion or sprayed onto the entire composition, the entire composition being colored homogeneously.
- an aqueous solution or dispersion of one or more dyes it is also possible for an aqueous solution or dispersion of one or more dyes to be applied to one or more ingredients of the composition and for the colored particles to be introduced into the compositions as colored particles ("speckles") become.
- This method has the advantage that a well-defined amount of dye contained in the agent only adheres to a certain percentage of the particles of the agent and stains them more intensely.
- the colored speckles are particularly noticeable.
- Such intensely colored speckles can be used both in powdery or granular compositions and in sediment-stabilized liquid products.
- the granular mixtures can also be pressed into shaped bodies and the detergent tablets thus speckled with ease.
- ingredients of automatic dishwashing agents are suitable as carrier material for the dye (s), substances from the group of phosphates, silicates, citrates, carbonates and sulfates being used with advantage, and sodium carbonate and sodium tripolyphosphate being preferred.
- the speckle particles are usually produced by applying an aqueous dye solution or dispersion to the carrier, where appropriate auxiliaries such as surfactants, emulsifiers, thickeners, antioxidants and other solutions may be contained in the dye solution.
- the dye solution which is applied to the support usually has a dye content of 1.0 to 15.0% by weight, preferably 2.0 to 10.0% by weight and in particular 4.5 to 8 , 0% by weight.
- Lower alcohols such as ethanol, isopropanol and glycols are particularly suitable as auxiliaries which can be present in the dye solution.
- Solubilizers or emulsifiers which are advantageously used in such dye solutions are, in particular, alkoxylated nonionic surfactants with less than 6 alkylene oxide groups and polyethylene glycols or polypropylene glycols.
- speckles are produced, their dye content, based on the weight of the speckles, is usually between 0.1 and 1.5% by weight, preferably between 0.15 and 1.0% by weight and in particular between 0.25 and 0.75% by weight.
- the carrier materials usually make up more than 85% by weight, preferably more than 90% by weight and in particular more than 95% by weight of the speckle weight, the rest are other active ingredients and auxiliaries.
- the amount of the dyes mentioned in the detergents is 0.01 to 1% by weight, preferably 0.02 to 0.5% by weight. and in particular 0.05 to 0.25% by weight, in each case based on the total average.
- Another area of application for the optically attractive dyeing of machine dishwashing detergents is detergent tablets, in which certain areas are optically highlighted by coloring.
- multilayer tablets can be produced in which one layer contrasts in color with the other layer (s).
- the production of ring / core tablets with differently colored areas is also possible without problems within the scope of the present invention. It is particularly preferred to use the dyes mentioned in two-layer mold bodies in which only one of the two layers contains one or more dyes from the group mentioned.
- Another object of the present invention is a solid or liquid machine dishwashing detergent, containing builders, surfactant (s), bleach and optionally other conventional ingredients, one or more dyes from the Ponceau 4R group (CAS No. 2611-82 -7, Cl 16255), Allura Red 40 (CAS No. 25956-17-6, Cl 16035), aluminum red RLW (Cl Mordant Red 83), Supranol ® Red GW (CAS No. 61901-44-8) , Basantol ® Red 310 (CAS No. 61951-36-8), Basacid ® Green 970 (CAS No.
- agents are suitable for machine dishwashing and have the advantage over conventional agents that the dyes they contain are stable with respect to the ingredients, do not discolor or discolor and do not impair the stability of the other ingredients.
- the dishes mentioned do not stain the dishes or the dishwasher, and the formation of colored deposits also does not occur.
- Another advantage of the agents mentioned is that the dyes they contain are physiologically completely harmless, so that contact with dishes or cutlery is possible without any problems.
- preferred agents contain the dyes mentioned in amounts of from 0.01 to 1% by weight, preferably from 0.02 to 0.5% by weight and in particular from 0.05 to 0.25% by weight. %, each based on the total mean. Examples:
- Red dye solutions of the following composition were prepared (data in% by weight):
- the solutions were sprayed onto carrier materials, 10 parts by weight of the above-mentioned dye solution being applied to 90 parts by weight of carrier material.
- Sodium tripolyphosphate (a) and sodium carbonate (b) were used as carrier materials.
- the colored particles were dried, stored for 14 days at room temperature with exclusion of air and visually assessed against freshly prepared and dried blank samples, the following evaluation scheme being used:
