Definitions
- the present invention relates to washing processes which are primarily intended for use in commercial laundries and in which optical brighteners are metered into the wash liquor separately from other constituents of the detergent.
- the invention relates to a method for washing textiles, in which optical brighteners are added to the wash liquor separately from the main amount of the active washing substances, characterized in that the brighteners are added in the form of a liquid aqueous preparation which contains at least one brightener from the class which contains dibenzofuranylbiphenyls and at least one brightener from the class of distyrylbiphenyls.
- the invention further relates to liquid aqueous brightener preparations which contain brighteners from these two classes and nonionic surfactants in certain amounts.
- the brightener combination according to the invention enables uniform brightening in the entire temperature range of interest from 30 to 100 ° C. Their use does not lead to so-called spotting (local decolorization) when in direct contact with colored laundry.
- this brightener combination is extremely stable against strong oxidizing agents, such as peracetic acid and chlorine, which are usually used in commercial laundries as bleaching and disinfecting agents, as well as against strong alkalis and the acids used in laundries.
- the new washing process is therefore used particularly advantageously in the field of commercial laundry.
- the brighteners from the class of dibenzofuranylbiphenyls used in the liquid aqueous brightener preparation according to the invention are compounds having the basic structure of the formula I.
- This brightener is also commercially available under the name Tinopal ® PLC (Fima Ciba). If desired, the brightener preparation can also contain several brighteners from the class of the dibenzofuranylbiphenyls.
- the liquid aqueous preparation used according to the invention contains at least one brightener from the class of distyrylbiphenyls, which are also referred to as distilbene brighteners. They have the basic structure shown in Formula III
- the terminal phenyl groups can be substituted one or more times, independently of one another, substituents from the group consisting of lower alkyl (1 to 4 carbon atoms), lower alkoxyl (1 to 4 carbon atoms), CN, Cl, Al- koxycarbonyl, amidocarbonyl and sulfonic acid groups, optionally in salt form, preferably sodium sulfonyl, can be selected.
- substituents from the group consisting of lower alkyl (1 to 4 carbon atoms), lower alkoxyl (1 to 4 carbon atoms), CN, Cl, Al- koxycarbonyl, amidocarbonyl and sulfonic acid groups, optionally in salt form, preferably sodium sulfonyl, can be selected.
- Those substances are preferably used which contain at least two sulfonate groups, in particular 4,4'-distyrylbiphenyl disulfonates. These compounds are preferably in the form of the sodium salts.
- This compound is also commercially available under the name Tinopal ® CBS / X (Ciba).
- the preparations according to the invention can of course also contain more than one brightener from the class of the distyrylbiphenyls.
- the content of brighteners from the class of dibenzofuranylbiphenyls in the liquid aqueous brightener preparation used according to the invention is preferably about 0.1 to about 2% by weight, in particular about 0.5 to about 1.5% by weight, based on the entire preparation.
- the preparation preferably contains about 0.1 to about 1% by weight, in particular about 0.3 to about 0.8% by weight.
- the liquid aqueous brightener preparations used according to the invention should preferably contain the brighteners in a fully solubilized form, ie the preparations should be transparent. If the brighteners used do not have sufficient water solubility, complete solubilization can be achieved by adding suitable auxiliaries.
- the most important auxiliaries for this purpose are surfactants, solubilizers and water-soluble organic solvents, which will be explained in more detail below.
- Suitable surfactants are surfactants of all known classes, but in particular anionic and nonionic surfactants, of which the nonionic surfactants are again particularly preferred.
- Alkanesulfonamides can be used for the preparations used according to the invention.
- addition products of ethylene oxide with alkylphenols with 6 to 16 carbon atoms in the alkyl chain are also suitable, but they are only reluctantly used because of their low biodegradability.
- part of the ethylene oxide can also be replaced by propylene oxide (PO). It is also possible to close the terminal hydroxyl group present in the alkoxylates by etherification with short-chain alcohols or with alkyl epoxides.
- the addition products of 3 to 20 mol of ethylene oxide and optionally propylene oxide with primary alcohols, such as, for example, with coconut or tallow fatty alcohols, with oleyl alcohol, with oxo alcohols or with secondary alcohols each having 8 to 18, preferably 12 to 18, carbon atoms are particularly important.
- nonionic surfactants which are obtained by ethoxylation of 3 Ci / i 5 oxo alcohol having 3 to 5 moles of EO, by alkoxylation of C 12 / ⁇ -Fettal- alcohol having from 4 to 6 moles of EO and 3 to be particularly preferred in the context of the invention 5 moles of PO and 14 / i 8 fatty alcohol with 0.5 to 2 moles PO, and 15 to 20 moles of EO and additional by alkoxylation of C End group closure with C 8 / ⁇ 2 - ⁇ -olefin epoxide is obtained because these surfactants provide very stable, clear brightener formulations even at low concentrations.
- the amount of surfactants in the brightener preparations is selected as required and is usually not more than about 10% by weight. Preferably between about 0.2 and about 7% by weight and in particular between about 0.2 and about 6% by weight of surfactants are used in the brightener preparations. Nonionic surfactants are preferably used alone.
- Suitable solubilizers for the brightener preparations are primarily the compounds also referred to as hydrotropes from the group of the salts of short-chain aliphatic and aromatic sulfonic acids and short-chain monoalkylsulfuric acids.
- solubilizers are sodium cumene sulfonate, sodium toluenesulfonate and sodium octyl sulfate.
- Long-chain monoalkyldiphenyl ether disulfonates which are available, for example, under the names Dowfax 3B2 and Dowfax 8390, may be mentioned as further possible solubilizers.
- the amount of solubilizers in the brightener preparations can be up to about 5% by weight. Preferably, their amount is between about 0.5 and about 3% by weight.
- water-soluble alcohols can be added as solubilization aids to the preparations used according to the invention.
- suitable alcohols are the monoalcohols having 1 to 4 carbon atoms, in particular ethanol, n-propanol and isopropanol. Glycols and glycol ethers may be mentioned as further suitable alcohols.
- the amount of these lower water-soluble alcohols in the preparations used according to the invention can be up to about 10% by weight, preferably their amount is between about 1 and about 6% by weight.
- the brightener preparations used according to the invention can contain water-soluble polymers, in particular nonionic and anionic polymers, as a further auxiliary.
- Polymers which are usually used in washing processes as so-called graying inhibitors are preferably used.
- Polyethylene glycols and modified polyethylene glycols are preferably used as nonionic polymers.
- An example of a preferred polymer of this type is the product from BASF sold under the name Sokalan HP 22 G.
- polymeric polycarboxylates which are preferably used as alkali salts, especially sodium salts.
- These are preferably polymers of olefinic monomers which contain at least one monomer from the group consisting of acrylic acid, methacrylic acid and maleic acid.
- polymers examples include the copolymers prepared from maleic acid and acrylic acid, which are marketed by BASF under the names Sokalan CP 5 and Sokalan CP 7.
- the content of water-soluble polymers in the brightener preparations can be up to about 10% by weight and is preferably between about 2 and about 7% by weight.
- the brightener preparation can also contain further auxiliaries and additives, provided that this combination does not interfere with the use of the brightener preparation according to the invention.
- Preservatives, dyes and perfume may be mentioned as additional auxiliaries.
- the concentration also depends on the intended effect.
- Preservatives such as, for example, formaldehyde, glutaraldehyde or didecyldimethylammonium chloride, can be present in the preparations in amounts of up to 1% by weight, preferably in amounts of between 0.01 and 0.2% by weight be included.
- typical detergent ingredients such as complexing agents, enzymes or alkalis, can also be added to the brightener preparation, if this should be expedient in individual cases to supplement the wash liquor.
- the process according to the invention does not differ from previously known washing processes.
- the detergent active substances can be dosed in the form of a basic detergent that contains all the active ingredients required for the washing process, with the exception of the brightener, in the correct ratio.
- a basic detergent for the production of the wash liquor which contains only some of the necessary active ingredients and to add the other active ingredients separately, for example in the form of surfactant enhancers, bleaches or disinfectants.
- the separate metering of individual or several active substances has the advantage that the composition of the wash liquor can be better adapted to the requirements resulting from the textile quality and the type of soiling. Accordingly, the composition of the wash liquor in the process according to the invention can also be varied within wide limits.
- the wash liquor used preferably contains at least one active ingredient each from the group of complexing agents, washing alkalis and surfactants. Preferred concentration ranges for these active substances in the washing liquor are approximately the following: complexing agents 20 ppm to 150 ppm, washing alkalis 50 ppm to 3000 ppm and surfactants: 50 ppm to 400 ppm.
- Further constituents of the wash liquor can be, in particular, graying inhibitors, bleaching agents, disinfectants, enzymes and perfume.
- the liquid aqueous brightener preparation used according to the invention can be added at any time during the production of the wash liquor. Dosing is also possible after the washing process has already started. NEN, ie after the textiles have been added to the wash liquor. Due to the liquid state of the preparation - the viscosities at 20 ° C are preferably between about 10 mPas and about 100 mPas (measured with a Brookfield rotary viscometer at 50 revolutions per minute and spindle 2) - the brightener preparations used can be effortlessly used with the help of measuring cups or dosed mechanically with the help of simple liquid pumps, such as are often already available in commercial washing machines for other purposes.
- the amount of brightener preparation that is added to the wash liquor is preferably selected so that the total brightener concentration in the brine is between about 2 ppm and about 20 ppm, in particular between about 4 ppm and about 8 ppm.
- the preparation of the liquid aqueous brightener preparation used according to the invention presents no particular problems and can be done by simply mixing the components. If necessary, it may be advisable to first dissolve poorly soluble brighteners with the appropriate auxiliaries before the total amount of water is added.
- the brightener preparations A to F listed in Table 1 were prepared by mixing the individual components.
- the numbers in the table mean percent by weight, based on the finished brightener preparation as a whole. All preparations were in the form of transparent solutions and kept this form even during storage for 8 weeks in an alternating climate between -5 ° C and +40 ° C.
- Brightener preparation A 4 or 8 ml
- the detergent components used had the following composition (in percent by weight):
- Brightener preparations B to F achieved equally good results.
