Definitions

- textile washing In addition to removing odors and, if necessary, scenting the textiles, textile washing generally primarily serves to remove soiling of all kinds. This cleaning effect is supported by the use of bleaches, surfactants and builders in the wash liquor, with the bleaching agent playing a major role in removing particularly colored soiling.
- peroxygen compounds are generally used as bleaching agents, the oxidative bleaching power of which is conventionally enhanced by so-called bleach activators, which form percarboxylic acids such as peracetic acid, for example through perhydrolysis of carboxylic acid derivatives such as TAED, which are more oxidizing than the starting peroxygen compound .

- alk (en) yl sulfates the alkali and in particular the sodium salts of sulfuric acid half esters of Ci2-Ci8 fatty alcohols, for example from coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the Cio-C2o-oxo alcohols and those secondary half esters Alcohols of these chain lengths are preferred.
- alk(en)yl sulfates of the chain length mentioned which contain a synthetic, straight-chain alkyl radical produced on a petrochemical basis, which have a degradation behavior analogous to that of the appropriate compounds based on oleochemical raw materials.
- the C12-C16-alkyl sulfates and C12-Ci5-alkyl sulfates and also C14-Ci5-alkyl sulfates are preferred for reasons of technical washing interest.
- the sulfuric acid monoesters of the straight-chain or branched C7-2i alcohols ethoxylated with 1 to 6 moles of ethylene oxide such as 2-methyl-branched Cg-n-alcohols with an average of 3.5 moles of ethylene oxide (EO) or C12-i8 fatty alcohols with 1 up to 4 EO are suitable.

- Suitable anionic surfactants are also the salts of alkyl sulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic esters and are monoesters and/or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and in particular ethoxylated fatty alcohols.
- Preferred sulfosuccinates contain Ca is fatty alcohol residues or mixtures of these.
- Particularly preferred sulfosuccinates contain a fatty alcohol residue which is derived from ethoxylated fatty alcohols which, considered in themselves, represent nonionic surfactants.
- sulfosuccinates whose fatty alcohol radicals are derived from ethoxylated fatty alcohols with a narrow homolog distribution are particularly preferred. It is also possible to use alk(en)ylsuccinic acid preferably having 8 to 18 carbon atoms in the alk(en)yl chain or salts thereof.
- Soaps come into consideration as further anionic surfactants.
- Saturated fatty acid soaps such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid, and in particular soap mixtures derived from natural fatty acids, e.g. coconut, palm kernel or tallow fatty acids, are suitable.
- the anionic surfactants can be in the form of their sodium, potassium or ammonium salts, as well as soluble salts of organic bases such as mono-, di- or triethanolamine.
- the anionic surfactants are preferably in the form of their sodium or potassium salts, in particular in the form of the sodium salts.
- cationic and/or amphoteric surfactants can also be used.
- cationic compounds of the following formulas can be used as cationic active substances:
- Textile softening compounds can be used to care for the textiles and to improve the textile properties, such as a softer handle 1 (finish) and reduced electrostatic charging (increased wearing comfort).
- the active ingredients of these formulations are quaternary ammonium compounds with two hydrophobic residues, such as disteraryldimethylammonium chloride, which, however, is increasingly being replaced by quaternary ammonium compounds that contain ester groups in their hydrophobic residues as predetermined breaking points for biodegradation because of its insufficient biodegradability.
- esters with improved biodegradability can be obtained, for example, by esterifying mixtures of methyldiethanolamine and/or triethanolamine with fatty acids and then quaternizing the reaction products with alkylating agents in a manner known per se.
- Dimethylolethylene urea is also suitable as a finish.
- Enzymes can be used to increase the performance of detergents. These include, in particular, proteases, amylases, lipases, hemicellulases, cellulases, perhydrolases or oxidoreductases, and preferably mixtures thereof. These enzymes are in principle of natural origin; Based on the natural molecules, improved variants are available for use in detergents and cleaning agents, which are used with preference accordingly.
- Detergents preferably contain enzymes in total amounts of 1 ⁇ 10 -6 % by weight to 5% by weight, based on active protein. The protein concentration can be determined using known methods, for example the BCA method or the Biuret method.
- subtilisin type those of the subtilisin type are preferred.
- subtilisins BPN' and Carlsberg and their further developed forms the protease PB92, the subtilisins 147 and 309, the alkaline protease from Bacillus lentus, subtilisin DY and the enzymes thermitase, which can be assigned to the subtilases, but no longer to the subtilisins in the narrower sense, Proteinase K and the proteases TW3 and TW7.
- amylases that can be used are the ⁇ -amylases from Bacillus licheniformis, from B. amyloquefaciens, from B.
- lipases or cutinases can be used. These include, for example, the lipases originally obtainable from Humicola lanuginosa (Thermomyces lanuginosus) or further developed from them, in particular those with the D96L amino acid substitution. Furthermore, for example, the cutinases can be used which were originally isolated from Fusarium solani pisi and Humicola insolens. It is also possible to use lipases and/or cutinases whose starting enzymes were originally isolated from Pseudomonas mendocina and Fusarium solanii.
- oxidoreductases for example oxidases, oxygenases, catalases, peroxidases such as halo-, chloro-, bromo-, lignin-, glucose- or manganese peroxidases, dioxygenases or laccases (phenol oxidases, polyphenol oxidases) can be used to increase the bleaching effect.
- organic, particularly preferably aromatic, compounds that interact with the enzymes are additionally added in order to increase the activity of the relevant oxidoreductases (enhancers) or to ensure the flow of electrons in the case of greatly differing redox potentials between the oxidizing enzymes and the soiling (mediators).
- the enzymes can be used in any form established in the prior art. These include, for example, the solid preparations obtained by granulation, extrusion or lyophilization or, in particular in the case of liquid or gel-like agents, solutions of the enzymes, advantageously as concentrated as possible, low in water and/or mixed with stabilizers.
- the enzymes can be encapsulated for both the solid and the liquid dosage form, for example by spray drying or extrusion of the enzyme solution together with a preferably natural polymer, or in the form of capsules, for example those in which the enzymes are enclosed as in a set gel or in those of the core-shell type, in which an enzyme-containing core is coated with a water, air and/or chemical impermeable protective layer.
- Additional active substances for example stabilizers, emulsifiers, pigments, bleaching agents or dyes, can also be applied in superimposed layers.
- Capsules are applied by methods known per se, for example by shaking or rolling granulation or in fluid-bed processes.
- such granules for example due to the application of polymeric film formers, produce little dust and are stable in storage due to the coating.
- enzymes and/or enzyme preparations preferably protease preparations and/or amylase preparations, in amounts of from 0.1% to 5% by weight, preferably from 0.2% to 4% by weight 5% by weight and in particular from 0.4% by weight to 4% by weight.
- Perfume oils or fragrances which can be used are individual fragrance compounds, for example synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. However, preference is given to using mixtures of different fragrances which together produce an appealing fragrance note. Perfume oils of this type can also contain natural mixtures of fragrances, such as those obtainable from vegetable sources, for example pine, citrus, jasmine, patchouli, rose or ylang-ylang oil. In order to be perceptible, a fragrance must be volatile, with the nature of the functional groups and the structure of the chemical compound also having an important role to play in terms of molar mass.
- fragrances have molar masses of up to about 200 g/mol, while molar masses of 300 g/mol and above tend to be an exception.
- the smell of a perfume or fragrance composed of several fragrances changes during evaporation, whereby the odor impressions are divided into “top note” (top note), “middle note or middle note” (middle note or body) and “base note” (end note or dry out). Since the perception of smell is also based to a large extent on the intensity of the smell, the top note of a perfume or fragrance does not consist solely of volatile compounds, while the base note consists for the most part of less volatile, i.e. adherent fragrances.
- fragrances When composing perfumes, more volatile fragrances can be bound to certain fixatives, for example, which prevents them from evaporating too quickly. In the following classification of the fragrances into “easily volatile” and “adherent” fragrances, nothing is said about the odor impression and whether the corresponding fragrance is perceived as a top or middle note.
- the fragrances can be processed directly, but it can also be advantageous to apply the fragrances to carriers that ensure a long-lasting fragrance through slower fragrance release. Cyclodextrins, for example, have proven useful as such carrier materials, and the cyclodextrin-perfume complexes can also be coated with other auxiliaries.
- colorant When choosing the colorant, care must be taken to ensure that the colorant has a long shelf life and is insensitive to light and does not have too great an affinity for textile surfaces and, in particular, for synthetic fibers. At the same time, take into account that colorants can have different stabilities towards oxidation. In general, water-insoluble colorants are more stable to oxidation than water-soluble colorants. The concentration of the colorant in the detergent varies depending on the solubility and thus also on the sensitivity to oxidation. In the case of colorants which are readily water-soluble, colorant concentrations in the range from a few 10 -2 % by weight to 10 -3 % by weight are typically chosen.
- the suitable concentration of the colorant in detergents is typically a few 10 -3 % by weight to 10 -4 % by weight.
- Coloring agents are preferred which can be destroyed by oxidation in the washing process, and mixtures thereof with suitable blue dyes, so-called blue toners. It has proven advantageous to use coloring agents which are soluble in water or in liquid organic substances at room temperature.
- Anionic colorants for example anionic nitroso dyes, are suitable, for example.
- the detergents can contain other ingredients which further improve the performance and/or aesthetic properties of these detergents.
- Preferred agents contain one or more substances from the group of electrolytes, pH adjusters, fluorescent agents, hydrotopes, foam inhibitors, silicone oils, antiredeposition agents, optical brighteners, graying inhibitors, shrinkage inhibitors, anti-crease agents, dye transfer inhibitors, antimicrobial active ingredients, germicides, fungicides, antioxidants, antistatic agents , ironing aids, repellents and impregnating agents, swelling and non-slip agents and UV absorbers.
- a large number of the most varied salts can be used as electrolytes from the group of inorganic salts.
- Preferred cations are the alkali and alkaline earth metals, preferred anions are the halides and sulfates. From a manufacturing point of view, the use of NaCl or MgCh in the detergents is preferred.
- pH adjusters In order to bring the pH value of detergents into the desired range, the use of pH adjusters can be indicated. All known acids or bases can be used here, provided their use is not prohibited for technical or ecological reasons or for reasons of consumer protection. The amount of these extenders does not usually exceed 1% by weight of the total formulation.
- Suitable foam inhibitors are soaps, oils, fats, paraffins or silicone oils, which can optionally be applied to carrier materials.
- suitable carrier materials are inorganic salts such as carbonates or sulfates, cellulose derivatives or silicates, and mixtures of the aforementioned materials.
- preferred agents contain paraffins, preferably unbranched paraffins (n-paraffins) and/or silicones, preferably linear-polymeric silicones, which are built up according to the scheme (R2SiO) x and also are referred to as silicone oils.
- silicone oils are usually clear, colorless, neutral, odorless, hydrophobic liquids with a molecular weight between 1000 g/mol and 150000 g/mol and viscosities between 10 mPa s and 1000000 mPa s.
- nonionic cellulose ethers such as methylcellulose and methylhydroxypropylcellulose containing 15 to 30% by weight of methoxy groups and 1 to 15% by weight of hydroxypropyl groups, based in each case on the nonionic cellulose ether.
- the soil repellents are the polymers of phthalic acid and/or terephthalic acid or derivatives thereof known from the prior art, in particular polymers of ethylene terephthalate and/or polyethylene glycol terephthalate or anionically and/or nonionically modified derivatives of these. Particularly preferred of these are the sulfonated derivatives of the phthalic and terephthalic acid polymers.
- Optical brighteners can be added in particular to detergents in order to eliminate graying and yellowing of the treated textiles. These substances attach to the fiber and cause lightening and feigned bleaching by converting invisible ultraviolet radiation into visible longer wavelength light, the ultraviolet light absorbed from sunlight being emitted as a faint bluish fluorescence and pure with the yellow hue of graying or yellowed laundry results in white.
- Suitable compounds come, for example, from the substance classes of 4,4'-diamino-2,2'-stilbenedisulfonic acids (flavonic acids), 4,4'-distyrylbiphenylene, methylumbelliferones, coumarins, dihydroquinolinones, 1,3-diarylpyrazolines, naphthalic acid imides, benzoxazole , benzisoxazole and benzimidazole systems as well as pyrene derivatives substituted by heterocycles.

- 4,4'-distyrylbiphenylene methylumbelliferones
- coumarins dihydroquinolinones
- 1,3-diarylpyrazolines 1,3-diarylpyrazolines
- naphthalic acid imides benzoxazole , benzisoxazole and benzimidazole systems
- the task of graying inhibitors is to keep the dirt that has been detached from the fibers suspended in the liquor and thus prevent the dirt from being reattached.
- Water-soluble colloids of mostly organic nature are suitable for this purpose, for example the water-soluble salts of polymeric carboxylic acids, glue, gelatin, salts of ether sulfonic acids of starch or cellulose or salts of acidic sulfuric acid esters of cellulose or starch.
- Water-soluble polyamides containing acidic groups are also suitable for this purpose.
- soluble starch preparations can be used, for example degraded starches and/or aldehyde starches. Polyvinylpyrrolidone is also useful.
- Cellulose ethers such as carboxymethyl cellulose (Na salt), methyl cellulose, hydroxyalkyl cellulose and mixed ethers such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof can also be used as graying inhibitors. Since textile fabrics, especially those made of rayon, viscose staple, cotton and mixtures thereof, can tend to wrinkle because the individual fibers are sensitive to bending, kinking, pressing and squeezing transversely to the fiber direction, synthetic anti-crease agents can be used.
- Repellent and impregnation processes are used to equip textiles with substances that prevent dirt from settling or make it easier to wash them out.
- Preferred repellents and impregnating agents are perfluorinated fatty acids, also in the form of their aluminum and zirconium salts, organic silicates, silicones, polyacrylic acid esters with a perfluorinated alcohol component or polymerizable compounds coupled with a perfluorinated acyl or sulfonyl radical.
- Antistatic agents can also be included.
- the dirt-repellent finish with repellents and impregnating agents is often classified as an easy-care finish.
- the penetration of the impregnating agents in the form of solutions or emulsions of the relevant active substances can be facilitated by adding wetting agents which reduce the surface tension.
- Another area of application for repellents and impregnating agents is the water-repellent finish of textile goods, tents, tarpaulins, leather, etc., in which, in contrast to waterproofing, the fabric pores are not closed, so the fabric remains breathable (hydrophobing).
- the hydrophobing agents used for hydrophobing coat textiles, leather, paper, wood, etc. with a very thin layer of hydrophobic groups such as longer alkyl chains or siloxane groups. Examples of suitable water repellents are paraffins, waxes, metal soaps, etc.
- silicone-impregnated textiles have a soft feel and are water and dirt-repellent; Stains from ink, wine, fruit juice and the like are easier to remove.
- Antimicrobial agents can be used to combat microorganisms. Depending on the antimicrobial spectrum and mechanism of action, a distinction is made between bacteriostatics and bactericides, fungistatics and fungicides. Substances from these groups are, for example, benzalkonium chlorides, alkyl aryl sulfonates, halogenated phenols and phenol mercuri acetate, although these compounds can also be dispensed with entirely.
- the agents can contain antioxidants.
- This class of compounds includes Wisely substituted phenols, hydroquinones, catechols and aromatic amines as well as organic sulfides, polysulfides, dithiocarbamates, phosphites and phosphonates.
- Antistatic agents increase the surface conductivity and thus enable an improved flow of charges that have formed.
- External antistatic agents are generally substances with at least one hydrophilic molecular ligand and form a more or less hygroscopic film on the surface. These mostly surface-active antistatic agents can be divided into nitrogen-containing (amines, amides, quaternary ammonium compounds), phosphorus-containing (phosphoric esters) and sulfur-containing (alkyl sulfonates, alkyl sulfates) antistatic agents.
- Lauryl (or stearyl) dimethylbenzyl ammonium chlorides are also suitable as antistatic agents for textiles or as an additive to detergents, with an additional finishing effect being achieved.
- Silicone derivatives can be used in laundry detergents to improve the water absorption capacity, the rewettability of the treated textiles and to facilitate ironing of the treated textiles. These also improve the rinsing behavior of detergents thanks to their foam-inhibiting properties.
- Preferred silicone derivatives are, for example, polydialkyl or alkylaryl siloxanes in which the alkyl groups have one to five carbon atoms and are wholly or partially fluorinated.
- Preferred silicones are polydimethylsiloxanes, which can optionally be derivatized and are then amino-functional or quaternized or have Si-OH, Si-H and/or Si-Cl bonds.
- Further preferred silicones are the polyalkylene oxide-modified polysiloxanes, ie polysiloxanes which contain, for example, polyethylene glycols, and the polyalkylene oxide-modified dimethylpolysiloxanes.
- UV absorbers can also be used, which are absorbed by the treated textiles and improve the light resistance of the fibers.
- Compounds which have these desired properties are, for example, the compounds and derivatives of benzophenone having substituents in the 2- and/or 4-position which are active by radiationless deactivation.
- substituted benzotriazoles acrylates phenyl-substituted in the 3-position (cinnamic acid derivatives), optionally with cyano groups in the 2-position, salicylates, organic Ni complexes and natural substances such as umbelliferone and endogenous urocanic acid.
- Protein hydrolysates are other suitable active substances due to their fiber-care effect. Protein hydrolyzates are product mixtures that are obtained through acidic, basic or enzymatically catalyzed degradation of proteins (proteins). Protein hydrolyzates of both plant and animal origin can be used. Animal protein hydrolysates are, for example, elastin, collagen, keratin, silk and milk protein hydrolysates, which can also be present in the form of salts. The use of protein hydrolyzates of vegetable origin, for example soybean, almond, rice, pea, potato and wheat protein hydrolyzates, is preferred.
- amino acid mixtures obtained in other ways or individual amino acids such as, for example, arginine, lysine, histidine or pyroglutamic acid can also be used in their place. It is also possible to use derivatives of protein hydrolyzates, for example in the form of their fatty acid condensation products.
- the detergents can be in the form of shaped bodies.
