Description

Detergent for fabrics woven from polyester fibers Field of invention The field of this invention relates to the following: -Washing clothes with an automatic washing machine. -A cleaning compound that provides high hydrophobic dirt removal performance from dirty fabrics. -A cleaning compound that increases the efficiency of removing grease stains and stains from fabrics woven from polyester fibers. - A cleaning composition that, using a dirt-releasing polymer, imparts sustainable dirt-dispersing properties to woven polyester fiber fabrics. -A cleaning composition that utilizes the interaction of a percompound, visual brighteners, photobleaches, and a soil release polymer to whiten, clean, and brighten synthetic fabrics. -A cleaning compound that increases the whitening and brightening of fabrics. This request is particularly relevant to specific compounds that meet all the requirements in this area. Background of the inventionWith the advancement of technology, fabrics are washed all over the world by washing machines using detergent-containing detergents. Consumers are constantly looking for detergents that increase the cleanliness of the fabric and maintain its original color even after repeated washing. Consumers are becoming obsessive about washing white fabrics (because the color white evokes cleanliness). For this reason, they want to have fabrics that are as white and new as the first day. However, when wearing and washing white fabrics, their color changes can be observed. In addition, frequent washing of white fabrics causes their color to turn yellow, which makes the fabrics look old, worn and dark, as if the fabrics were not really cleaned. Hence, consumers wash their fabrics at high temperatures, especially above 60 degrees Celsius, to make the fabrics look new and whiter. Also, washing fabrics at temperatures below 10 degrees Celsius does not clean them.Many detergents improve washing by removing all types of dirt when using hot water because hot water softens dirt and helps surfactants to remove dirt from the fabric. However, washing fabrics with hot water weakens the fabric texture. In addition, in some parts of the world, hot water is not available for washing, and for economic and environmental reasons, hot water is not feasible. As a result, consumers prefer to use detergents containing detergents at high temperatures. However, washing fabrics using detergents at high temperatures increases the weakening of the fabric texture. Therefore, the object of this invention is to provide a detergent composition that provides excellent cleaning of white fabrics when washed with hot or cold water. Manufacturers have made great efforts to meet customer expectations for the whiteness of fabrics, depending on the type of fabric, because the needs of consumers of consumer products determine the production and marketing processes. Today, a significant amount of polyester fibers are used in the production of textile materials, because compared to cotton woven fabrics, polyester fibers increase the resistance to abrasion and wrinkling of clothing. Despite the high strength and durability of polyester and polyester blend fabrics, these fibers are hydrophobic in nature, which makes them difficult to wash because polyester and polyester blend fabrics tend to retain oil stains and stains that are also hydrophobic. In addition, washing grease stains from the surface of polyester fabrics is very difficult even after several washes because these fibers tend to absorb and accumulate hydrophobic grease stains. This feature can be attributed to the low affinity of polyester fabrics for water, which reduces their wettability, as a result of which grease stains become difficult to wash.Therefore, the difficulty of cleaning and washing oily and greasy stains from polyester fabrics in turn increases the cost of the cleaning process, which is not desirable. Therefore, the object of this invention is to provide a detergent composition that provides excellent cleaning of polyester woven fabrics when washed with hot or cold water. In the near future, consumers are not expected to give up their preferences for durable and abrasion-resistant fabrics for economic reasons. Therefore, the washing performance of polyester woven fabrics must be improved. But this has been a serious challenge for the laundry industry. Accordingly, manufacturers are looking for ways to improve the hydrophilicity and wettability of polyester fabrics to improve and facilitate the cleaning and washing of grease stains from these fabrics. This can be achieved in two different ways: 1- by producing hydrophilic polyester fibers and fabrics 2- or by using polymers to increase the hydrophilicity of the fabrics during the washing process. The first approach is associated with a finishing process of the fibers or fabrics, in which the fabrics or fibers are immediately treated with a dirt release polymer to increase their hydrophilicity. Although this approach seems to be a good solution, the use of large amounts of dirt release polymers during the finishing process makes the fabrics stiffer. As a result, the fabrics lose their softness and desirable appearance.In addition, the hydrophilicity of the fabric decreases due to the removal of soil-releasing polymers after repeated washing or after harsh washing conditions (e.g., high temperature, high pH, ​​and detergents). The decrease in hydrophilicity of the fibers and fabrics leads to ineffective washing of oily stains. On the other hand, the second approach involves the use of detergents containing soil-releasing polymers, which increase the hydrophilicity and wettability of the fabrics through the continuous benefit of the soil-releasing polymers after each wash. Therefore, the object of this invention is to provide a detergent composition containing a soil release polymer that increases the hydrophilicity and wettability of polyester fabric to achieve excellent cleaning. Soil release polymers are fabric enhancers and detergent additives that have the ability to form a membrane around polyester fibers, thereby imparting soil-repelling properties to the surface of polyester fabrics. Using detergents containing soil release polymers prevents the fixation of dirt and oil stains and provides effective washing of soiled fabrics. Compared to surfactants and detergent builders, soil release polymers are superior detergent additives for the following reasons: I. They increase the water absorption (hydrophilicity) of the fabric and make it comfortable to wear. II. Significant improvement in washing by removing oil stains from the surface of polyester fabrics that are not possible using conventional detergents. III. Enhancement of the multiple washing effect, where the cleaning performance of fabrics is improved through repeated washings, as each wash stabilizes the amount of dirt-releasing polymer. But excessive use of dirt-releasing polymers makes fabrics stiff and rough, and the increased cost of the washing process causes consumers to change their opinions and preferences. Therefore, the object of this invention is to provide a detergent composition that has superior cleaning performance and imparts dirt-repellent properties to polyester fabric washed with it. A further object of this invention is to provide a detergent composition containing a soil release polymer, the effective amount of which is adjusted to provide excellent washing properties to fabrics woven from polyester fibers. Since soil release polymers exert their effect by forming a membrane on the surface of polyester fabrics, the washing conditions (especially temperature) are critical for the formation of membranes and adhesion of the soil release polymers. Washing at high temperatures prevents adhesion or increases the separation of the soil release polymer from the fabric. As a result, the reduced water absorption by the fabric leads to reduced soil release, reduced cleaning and washing performance of greasy fabrics. Temperature is also critical for other unavoidable detergent components (especially for the percompound, which is a mineral peroxide compound responsible for bleaching and stain removal by releasing hydrogen peroxide when dissolved in water). Their activity is temperature dependent and they show effective bleaching performance at temperatures above 60°C, which is not desirable in terms of cost, energy and fabric care. For this reason, the use of bleach activators is necessary to enhance the bleaching performance of hydrogen peroxide at temperatures below 60°C. However, this compound does not show effective performance in removing grease stains in cold or hot washes. Therefore, the object of this invention is to provide a detergent composition that provides superior cleaning and whitening of hydrophobic stains on the surface of polyester fabrics through the interaction of peroxyacid bleaches and a soil release polymer. Another object of this invention is to provide a detergent composition that provides effective and continuous whitening of synthetic fabrics at hot or cold temperatures. Consumers insist on their expectations of white fabrics being whitened during washing or drying. The terms used to refer to the cleaning performance of white fabrics are bleaching and brightening, which are responsible for the overall whitening of white fabrics. Bleaching is used to refer to the removal of dirt and stains during washing, while brightening is used to refer to the deposition of visual brighteners on fabrics. Visual brighteners are used to adjust the perception of whiteness through daylight. These brighteners deposit on the fabric surfaces, hiding the discoloration of the fabric and giving it a desirable whiteness. In fact, since whiteness can be judged by the perception of the brightness of the fabric, the use of visual brighteners and photobleachers increases consumers’ perception of the performance of the detergent composition. As a result, fabric whitening is a two-step process, the first step involving bleaching of dirt and the second step involving brightness adjustment. It is therefore an object of this invention to provide a detergent composition that provides superior bleaching of fabrics during washing or drying. A further object of this invention is to provide a detergent composition that provides superior whitening, cleaning and brightening of synthetic fabrics through the interaction of a percompound, visual brighteners, photobleach and soil release polymer. Another object of this invention is to provide a detergent composition that imparts soil release properties to hydrophobic fabrics to achieve superior cleaning, whitening, and brightening properties relative to a comparable amount of soil release polymer obtained from a free-flowing granular detergent composition. A further object of the invention is to provide an inexpensive detergent composition that imparts soil release properties to hydrophobic fabrics to achieve superior cleaning, whitening, and brightening in hot or cold water relative to a comparable amount of soil release polymer obtained from a free granular detergent composition. Cleaning compositions provide hydrophobic soil removal performance from soiled fabrics from EP2978831 and EP3039112. However, these compositions cannot achieve effective cleaning performance using soil release polymers alone. They require the incorporation of additional detergents such as polyetheramines. These provide better grease removal but do not whiten or brighten fabrics. The present invention overcomes the aforementioned problems by formulating particulate cleaning compositions. The compositions provide cleaning, whitening, and brightening of synthetic fabrics through the interaction of percompound, visual brighteners, photobleach, and soil release polymer. The cleaning composition of the present invention allows the consumer to continue using the product in a safe, environmentally friendly, effective, and inexpensive manner. Description of the invention This invention relates to the following: -Particle-based cleaning agents that are superior to commercial products on the market in terms of increased hydrophobic dirt removal performance from dirt-soaked fabrics made of polyester fibers. - Detergents with particles containing dirt-releasing polymers to create hydrophilicity and wettability of polyester fabric to achieve excellent cleaning. - Detergents containing dirt-releasing polymer particles to increase the hydrophilicity and wettability of fabrics through the continued benefit of dirt-releasing polymers after each wash. -Particle-based detergents that are superior to commercial products on the market in terms of whitening and brightening white synthetic fibers in hot or cold water. -Particulate detergents that utilize the interaction of percompound, visual brighteners, photobleaches, and soil release polymers to whiten, clean, and brighten synthetic fabrics, superior to commercial products on the market. -Particle-based detergents with the aforementioned properties that allow the consumer to achieve better cleaning, whitening, and brightening performance of white fabrics in hot or cold water, and this is possible using the inventive product that facilitates easy, effective, economical, and less energy-intensive washing. Therefore, it is an object of this invention to provide an inexpensive detergent composition that imparts soil release properties to hydrophobic fabrics to achieve superior cleaning, whitening and brightening in cold or hot water. The composition comprises the following: a) Anionic and nonionic surfactants b) Anionic dirt release polymer c) Compound (Percompound) d) Bleach activator e) Optical brighteners f)Photobleach g) Constructive system The inventive particulate detergent composition includes the following: a) Anionic surfactant 5.0% to 11.0%, preferably 6.0% to 10.0% and nonionic surfactant 0.5% to 4.0%, preferably 1.0% to 3.0% b) Pus release polymer 0.1% to 1.5%, preferably 0.2% to 1.2% of the total composition c) Composition 3.0% to 20%, preferably 3.5% to 17% of the total composition d) Bleach activator 1.0% to 6.0%, preferably 1.5% to 5.0% of the total composition e) Visual brighteners 0.05% to 1.5%, preferably 0.06% to 1.2% of the total composition f) Photobleach 0.01% to 0.02%, preferably 0.012% to 0.018% of the total composition This combination also has a constructive system. The term "particles" is used to refer to granules, powders, solids, and mixtures thereof. These terms can be used interchangeably. As mentioned above, a particulate detergent composition is used to coat granules, solids and / or powders. A particulate detergent composition and / or particulate detergents and / or particulate detergent compositions coat cleaning products for washing. Furthermore, the terms detergent and / or detergent composition and / or detergent composition are used interchangeably. The term "warm or cold wash" refers to washing fabrics at temperatures below 40°C. Pus release polymer Soil release polymers are used in detergent compositions to increase the hydrophilicity and wettability of synthetic fabrics (by forming a membrane on the surface of the fabric). These polymers are absorbed onto the fabric surface during washing, increasing the water absorption capacity of the fabric, which removes soil and oil stains. Soil release polymers are also often prepared by medium molecular weight copolymers containing ethylene terephthalate units randomly mixed with polyethylene glycol units. Soil release polymers can be anionic, nonionic, and cationic. Anionic dirt release polymers (especially polymers containing sulfo groups) have good water solubility, hence also effective dirt release performance. High water solubility is detrimental to storage stability. Therefore, the desired polymers are compatible with additives and auxiliaries commonly used in detergents and cleaners, these additives are based on polyethylene terephthalate-polyoxyethylene terephthalate copolymers (so-called PET-POET) and are supplied under the trade names TexCare® SRA 300 and 300F from Clariant. The amount of soil release polymer is also critical to the performance of the cleaning process. If less than 0.1% of the polymer is used, soil release and cleaning will not occur, and if more than 1.5% is used, the detergent performance will be saturated but the washing cost will increase. The amount of soil release polymer present in the inventive particulate cleaning composition is 0.1% to 1.5%, and preferably 0.2% to 1.2% of the total composition. The particulate cleaning composition includes an anionic soil release polymer consisting of a sulfonated polyester, an end-capped sulfonated polyester, a carboxylate-terminated polyester, and combinations thereof. Compound (PERCOMPOUND) The patented particle-based detergent composition ensures effective and continuous whitening of hydrophobic fabrics in hot or cold water, thanks to the combination with PERCOMPOUND. Percompounds are oxygen-releasing peroxide compounds that are effective bleaching agents. The preferred bleaching agent for laundry involves the use of hydrogen peroxide sources because it not only causes less damage to fabric fibers than other peroxygen sources, but also reduces fabric roughness, enzymes, and visual brighteners. Preferred sources of hydrogen peroxide for this invention can be selected from peroxides and / or persalts. In addition, preferred sources of bleaching are persalts that can be added to this invention and are selected from the following group: Perborates (e.g. perborate monohydrate, perborate tetrahydrate) - percarbonates - peroxyhydrates, persilicates and persulfates. Percarbonates are preferred for the following two reasons: I. Their high dissolution rate II. Simultaneous production of hydrogen peroxide and carbonate ions, which keeps the pH high in favor of perhydrolysis. The amount of Percompound present in the inventive particle cleaning composition is 3.0% to 20%, and preferably 3.5% to 17% of the total composition. The preferred source of percarbonate for this invention is: Alkali metal salts of percarbonates, sodium salts and preferably selected percarbonates as coatings to improve their stability. Whitening activator The inventive particulate detergent composition includes the use of organic bleach activators for the percompound because they do not show significant activity at low temperatures. The use of peroxy compounds with activators results in the formation of peroxyacid, which is the active species for bleaching. Since the activity of percompound is strongly temperature dependent, bleach activators are used to activate the bleaching agents at temperatures below 60°C. These activators accelerate the bleaching process so that bleaching can be carried out effectively at low temperatures. Bleach activators are perhydrolyzed to form peracid as the active bleaching agent. Bleaching in hot water is very important in terms of fabric care, cost and energy. Therefore, it is desirable to use cold or warm water because bleaching at moderate temperatures reduces the risk of fabric deformation and washing costs. In the compositions of this invention, the suitable bleaching activator can be selected from the following group of activators: Tetraacetylethylenediamine (TAED), nonavinyloxybenzene sulfonate (NOBS), sodium 4-(iso-nonavinyloxy)benzene sulfonate (iso-NOBS). The preferred activator for this invention is tetraacetylethylenediamine (TAED). TAED accelerates the bleaching process as follows: By reacting with hydrogen peroxide released by sodium percarbonate to produce peroxyacetic acid, which has a better bleaching efficiency than hydrogen peroxide, and the DAED (diacetylethylenediamine) molecule, which is no longer reactive. The amount of bleach activator present in the inventive particle cleaning composition is 1.0% to 6.0%, and preferably 1.5% to 5.0% of the total composition. The bleaching power of the inventive composition is increased by adding percompound and bleach activators. The use of percompound and bleach activators can be considered in their ratio. Use with a percompound / bleach activator ratio of less than 3.0 does not show any detectable activity, therefore effective bleaching is not performed. Use with a ratio of more than 17.0 is also not economical and also does not show effective performance due to ineffective activator ratio or oversaturation. Therefore, the percompound / bleach activator ratio is between 3.0 and 17.0, and preferably between 3.5 and 15.0. Photobleach Bleaching agents other than percompound are also used in particulate detergents to enhance the visual appearance of washed fabrics by enhancing their whitening properties through a photophysical mechanism. A photobleach is a light-sensitive molecule that undergoes a chemical change in another molecule in a photochemical process. When photobleachs absorb light, they ignite. When they reach their lowest energy, the energy released oxidizes oxygen to singlet oxygen, which is the effective bleaching agent of photobleachs. Singlet oxygen is an oxidizing species that reacts with stains and bleaches them. Because stains have a chemical and biological background, singlet oxygen reacts with them and disrupts their structure, making them colorless and water-soluble. As a result, the stains are removed. This process is also known as photochemical bleaching. Since singlet oxygen is not produced directly from low-energy oxygen under light, the use of colored photosensitizers is mandatory.Although the lifetime of singlet oxygen is from nano to picoseconds, the photosensitizer can continuously produce singlet oxygen under light. During washing and bleaching of fabrics and when hanging them under light to dry, photobleachs are deposited on the fabric. The most common photobleachs are phthalocyanine and porphyrin dyes. In the particulate cleaning composition of the present invention, a sulfonated tetrabenzo-tetraazaporphine derivative is used. The most common and simplest way to incorporate them into a detergent powder is to add these materials to the base powder before spray drying the slurry. The amount of photobleach present in the particulate cleaning composition of the present invention is 0.01 to 0.02% and preferably 0.012 to 0.018% of the total composition. Optical brighteners The amount of optical brighteners present in the particulate cleaning composition of the invention is 0.05 to 1.5%, and preferably 0.06 to 1.2% of the total composition. The optical brighteners can be selected from the following: -Carboxyls such as distyrylbenzenes, distyrylbiphenyls, and divinylstilbenes -Triazinylaminostilbene; stilbenyl-2H-triazoles such as stilbenyl-2H-naphthol[1,2-d]triazoles and bis(1,2,3-triazol-2-yl)stilbenes; -Benzoxazoles such as stilbenylbenzoxazoles and bis(benzoxazoles); -Furan, benzofuran and benzimidazoles such as bis(benzo[b]furan-2-yl)biphenyls and -Cationic benzimidazoles; 1,3-diphenyl-2-pyrazoline; coumarins; naphthalimides; 1,3,5-triazin-2-yl derivatives; methine cyanines; and dibenzothiphen-5,5-dioxide. Diphenylethylenetriazine and 4,4'-bis(2-sodium styryl sulfonate)biphenyl are preferably used as optical brighteners. Surfactants Surfactant reduces the surface tension of water; acts as a wetting agent that removes dirt. Surfactants suitable for such applications can be anionic, cationic, nonionic, and amphoteric. Depending on the desired concentration of the composition, the amount of surfactant used in this invention varies from about 1 to 50%. The cleaning composition of this invention includes anionic and nonionic surfactants. The preferred anionic surfactant is the sodium salt of linear alkylbenzene sulfonic acid (LABSA.Na). LABSA.Na is made by sulfonating linear alkylbenzene (LAB) (which produces linear alkylbenzene sulfonic acid (LABSA)) then neutralizing with sodium hydroxide to obtain LABSA.Na. The LAB used in the manufacture of LABSA.Na may be of the HF and / or Detal type. LAB used in the production of LABSA.Na includes: -Maximum 1% C9 phenyl, 8-18% C10 phenyl, 26-38% C11 phenyl, 26-38% C12 phenyl, 15-27% C13 phenyl, maximum 1% C14 phenyl of the total LAB weight. The amount of 2-phenyl isomer in LAB is 15-22% for the HF type and 25-35% for the Detal type. The resulting LABSA.Na has a minimum solids content of 96% and shows a similar carbon distribution to the LAB starting material. LABSA.Na is added to the cleaning compositions before the spray drying process (e.g. in a spray-dried slurry). Other suitable anionic surfactants can be of any type that is not heat sensitive and does not burn under the conditions of the spray drying process (used during the preparation of the powder base). Heat sensitive anionic surfactants can also be added to the compositions in granular form at a post-drying stage to cool to a lower temperature (which does not adversely affect the anionic surfactants). The use of LABSA-Na less than 5.0% does not show effective cleaning performance, and LABSA-Na above 11.0% does not show a significant change in cleaning performance. In addition, an excessive amount of LABSA-Na causes excessive foam formation during washing, which adversely affects the performance of enzymes and surfactants. Therefore, the amount of LABSA-Na present in the particulate cleaning composition of the present invention is 5.0 to 11.0%, and preferably 6.0 to 10.0% of the total composition. Nonionic surfactants are selected from the following groups: Ethoxylated alcohols, ethoxylated alkylphenols, fatty acid esters, alkyl polyglucosides, polyalcohols and ethoxylated polyalcohols. The preferred group of nonionic surfactants are ethoxylated alcohols selected from the following group: C12-C18 fatty alcohol ethoxylated with 5-9 EO, C12-C14 fatty alcohol ethoxylated with 6-10 EO, C16-C18 fatty alcohol ethoxylated with 10-80 EO, C13-C15 oxo alcohol ethoxylated with 3-11 EO, C10-C18 alcohol ethoxylated with 5-7 EO, C13 oxo alcohol ethoxylated with 2-20 EO, C10 ethoxylated with 3-14 EO, C10 oxo alcohol ethoxylated with 3-11 EO. The preferred nonionic surfactant of this invention is an ethoxylated C13-C15 oxo alcohol with 3-11 EO, and preferably the preferred nonionic surfactant of this invention is an ethoxylated oxo alcohol in which the number of ethoxy groups is 5 to 7, and preferably 7. The amount of nonionic surfactant present in this invention is 0.5 to 4.0% and preferably 1.0 to 3.0% of the total composition. Constructor system Builders mix in cleaning agents for the following reasons: -Softening water -Increase the cleansing effect -Preventing re-deposition and solid suspension during the washing process. In addition, they are expected to contribute to the cleaning performance by providing the necessary alkalinity for the washing process, increasing the adsorption capacity and surfactant effect. In the inventive composition, the inorganic and organic builders are combined to form a mutual builder system that helps to improve the whitening and brightening properties of the particulate cleaning composition of the invention. The particulate cleaning composition of the present invention comprises inorganic and organic builders, the inorganic builders being selected from the following: Carbonates, silicates, disilicates, polysilicates, soda silicate ash granules, zeolites. And organic builders can be chosen from the following: Polycarboxylate polymers such as polyacrylic acid and its salts, modified polyacrylic acid and its salts, acrylic / maleic copolymers, maleic acid / olefin copolymers; monomeric polycarboxylates such as citrates, gluconates, oxydisuccinates, glycerol mono-di- and trisuccinates, carboxymethyloxysuccinates, carboxymethyloxymalonates, dipicolinates, hydroxyethyliminodiacetates, alkyl and alkynylmalonates and succinates, and sulfonated fatty acid salts. Desirable organic and inorganic builders are present in the form of alkali metal salts, preferably in the form of sodium salts. The preferred builder systems of this invention contain sodium carbonate and sodium silicate as inorganic builders and sodium salt of polyacrylic acid as organic builder. Organic builders such as polyacrylic acid prevent graying of fabrics and improve the cleaning performance of detergents by absorbing ions responsible for water hardness. If the amount of polyacrylic acid builder in the detergent is less than 0.4%, the composition will not function properly, and if this amount is more than 4.0%, it will adversely affect the performance of enzymes because some enzymes require Ca2+ and Mg2+ ions to function properly. The use of an excess amount of polyacrylic acid builder will absorb Ca2+ and Mg2+ ions more than required, which will lead to improper performance of the enzymes and reduce cleaning performance. Therefore, the amount of organic builder present in the particulate cleaning composition of the present invention is 0.4% to 4.0%, and preferably 0.5% to 3.0% of the total composition. If the amount of silicate builder present in the detergent is less than 2%, effective cleaning performance is not achieved, and if this amount is more than 9.0%, the irritation potential increases. Therefore, the amount of silicate builder present in the particulate cleaning composition of the present invention is 2.0 to 9.0%, and preferably 3.0 to 8.0% of the total composition. If the amount of carbonate builder present in the detergent is less than 8.0%, effective cleaning performance is not achieved, and if this amount is more than 25.0%, the irritation potential increases. Therefore, the amount of carbonate builder present in the particulate cleaning composition of the present invention is 8.0% to 25.0%, and preferably 10.0 to 20.0% of the total composition. The preferred amount of soda ash disilicate / polysilicate granules in the detergent composition of the invention is up to 10% and preferably up to 5% by weight of the total composition. These granules are preferably added to the composition in the post-drying stage. The soda ash disilicate / polysilicate granules contain 45-55% sodium carbonate and 21-41% sodium salt of silicic acid. A non-limiting commercial example can be found under the brand name Nabion® from Novacarb France. Phosphonates Phosphonates can be used as builders or as bleaching agents, as stabilizers for peroxide solutions. Thus, the long-term activity of the percarbonate preservative and stability increase the effectiveness and cleaning power during the washing process. Phosphonate compounds are not sufficient for long-term bleaching in hand washing. These stabilizers are provided to protect the peroxides against iron and copper (such as the decomposition of heavy metal catalysts) and increase the bleaching effect of the percompound and activator system by inhibiting the harmful side reaction (which occurs between the peracid and the percompound formed in the washing solution). The peroxyacid compositions of this invention contain multiple chelating agents that act as stabilizers in addition to aminophosphonate and aminocarboxylate chelates. Phosphonates can be selected from the following: Aminotris(methylenephosphonic acid) - ATMP, (1-hydroxyethylidene)diphosphonic acid - HEDP, diethylenetriaminepenta(methylenephosphonic acid) - DTPMP or their corresponding salts. The preferred type of phosphonate in these detergent compositions is the sodium salt of DTPMP (DTPMP.Na). The amount of phosphonate present in the particulate cleaning composition of this invention is 0.05% to 0.4%, and preferably 0.1% to 0.3% of the total composition. Other ingredients Cellulosic polymer: The detergent compositions of this invention contain cellulosic polymers as antifouling agents selected from the following: Alkyl cellulose, alkyl alkoxyalkyl cellulose, carboxyalkyl cellulose, alkyl carboxyalkyl. The detergent composition of the present invention is based on the use of carboxymethyl cellulose as the cellulosic polymer. The amount of cellulosic polymer present in the particulate detergent composition of the present invention is 0.1 to 1.2%, and preferably 0.2% to 1.0% of the total composition. Foam Depressants: Detergent formulations contain up to 2% foam depressants. The preferred foam depressants are silicone-based. These are added to the cleaning formulations after the spray drying process (they are not present in spray-dried slurry). Enzyme: Cleaning compositions contain one or more detergent enzymes up to 2% by weight of the total composition. Examples of suitable enzymes include: Amylase, arabinosidase, β-glucanase, cellulase, chondroitinase, cotinase, esterase, hemicellulase, hyaluronidase, creatanase, laccase, ligninase, lipase, lipoxygenase, malanase, mannanase, oxidase, pectinase, pentosanase, peroxidase, phenoloxidase, phospholipase, protease, pullulanase, reductase, tannase and xylanase or a combination thereof. The preferred combination is a combination of enzymes such as protease, amylase, mannanase, cellulase, and lipase. The enzymes are added to the cleaning compounds after the spray drying process (they are not present in the spray dried slurry). Types of colorants: Cleaning compositions contain up to 5% of the total weight of the composition, types of colorants. These colorants can be salts and / or fatty soaps. Examples of salts include: Sodium salts, lithium salts, potassium salts, magnesium salts, calcium salts. Sodium salts are selected from the following: Sodium sulfate, sodium bisulfate, sodium carbonate, sodium chloride, sodium bicarbonate, sodium percarbonate, sodium nitrate, sodium nitrite, sodium thiosulfate, sodium acetate, sodium bromide, sodium chlorate, sodium perchlorate, sodium chromate, sodium dichromate, sodium iodide, sodium iodate, sodium oxalate, sodium silicate, sodium sulfide, sodium sulfite, sodium bisulfite, sodium citrate, sodium malate, sodium stearate, sodium lauryl sulfate, sodium benzoate, sodium bromate, sodium formate, sodium selenate, sodium periodate, sodium molybdate, sodium hydrates and mixtures thereof. The preferred salt is sodium sulfate. Various colorants are added to the cleaning compositions after the spray drying process (they are not present in the spray dried slurry). Filler: Detergent compositions contain fillers in the range of 10 to 60% by weight of the total composition. The filler can be selected from sulfate salts, sodium acetate, or sodium chloride. The main filler is preferably sodium sulfate. A small amount of magnesium sulfate (up to 2% by weight of the total composition) is also desirable in this detergent composition. Fillers are added to the detergent compositions after the spray drying process (they are not present in the spray dried slurry). Fragrance: Essential oils and / or encapsulated fragrances can be added to the cleaning composition. The amount of these fragrance ingredients is greater than 0 to 1%. Method of preparing the cleaning mixture The particulate cleaning composition of this invention is prepared by a two-step process that involves forming a slurry and adding an additive. In the first step, linear alkyl benzene sulfonic acid is dissolved in water and converted to its sodium salt (LABSA.Na) by adding an equal molar amount of NaOH. After the formation of the sodium salt of linear alkyl benzene sulfonate, the following materials are added to complete the formation of the detergent composition slurry: Sodium salt of polyacrylic acid, sodium salt of diethylenetriamine penta(methylenephosphonic acid) (DTPMP), optical brighteners, carboxymethylcellulose (CMC), sodium silicate, magnesium sulfate and sodium sulfate. The prepared slurry is then dried and powdered for use in the second stage.

This completes the particulate cleaning composition. Example 1: Preparation of a cleaning composition containing particles of the invention in question 7.78 g of linear alkyl benzene sulfonate was dissolved in water and converted to its sodium salt (LABSA.Na) by adding an equal molar amount of 2.02 g of 49% NaOH (aq) solution to form 8.0 g of LABSA.Na. The resulting mixture was stirred until the reaction mixture cooled to room temperature. After adding 1.50 g of sodium salt of polyacrylic acid 0.16 g of diethylenetriamine penta(methylenephosphonic acid) sodium salt (DTPMP), 0.10 g of optical brightener, 0.4 g of carboxymethylcellulose (CMC), 4.0 g of sodium silicate, 1.0 g of magnesium sulfate were added. Sodium sulfate is added to complete the total weight of the cleaning composition to 100.0 g. In the Additive Addition section, the granule composition was completed by adding the following ingredients: 1.50 g C13-C15 oxo alcohol ethoxylated with 7 EO - 1.0 g anionic dirt release polymer - 17.0 g sodium percarbonate - 1.6 g tetraacetylethylenediamine (TAED) - 0.015 g photobleach - 0.08 g enzyme, 4.0 g disilicate / polysilicate - soda ash granules - 1.0 g antifoam - 0.4 g perfume - 0.8 g sodium sulfate dye - 0.3 g preservative and 17.5 g sodium carbonate. This completes the preparation of the particulate cleaning composition.

Release of dirt and detergent Pus release: Comparative wash results of the compositions of Example 1 and Example 8 on selected stains The dirt release performance of Example 1 was determined both visually and spectrophotometrically using 5 different pure stains, namely mixed oil, sunflower oil, corn oil, tuna oil and sesame oil mixed with soybean oil. For this purpose, the fabrics of Example 1 and Example 8 were washed before and after being stained with pure stains at 20°C and under similar conditions. The test results are shown in Table 2. Table 2: Results of visual and spectrophotometric evaluation of pus release performance in Example 1 and Example 8 Visual assessment Spectrophotometric assessment of stains Example 1 Example 8 Example 1 Example 8 Mixed oil 4.5 4.0 4.0 3.5 Sunflower oil 4.0 3.5 4.0 3.5 Corn oil 4.5 4.0 4.0 3.5 Tuna oil 4.5 4.0 4.0 3.5 Sesame oil mixed with soybean oil 4.0 3.5 4.0 3.5 The dirt release performance of Example 1 and Example 8 was also visually determined for the engine oil stain and based on the visual evaluation test results of Example 1 and Example 8, they are 4.0 and 3.5, respectively. The results of the visual and spectrophotometric evaluation presented in Table 2 clearly show that fabrics rinsed at 20°C with the composition of Example 1 (which contains the dirt release polymer) are cleaned much more easily and effectively than fabrics rinsed with Example 8. The dirt release polymer improves the hydrophilicity and wettability of synthetic fabrics by forming a membrane on their surfaces, which removes dirt and oily stains. Detergent for one wash and multiple washes: Comparative results of one wash and multiple washes of the composition of Example 1 on selected stains The soil release performance in single and repeated washes of Example 1 was determined visually or spectrophotometrically. To determine the single wash performance, the polyester fabrics were not washed before staining and were stained with pure type stains. After staining, the fabrics were washed with the composition of Example 1. To determine the repeated wash performance, the fabrics were washed with the composition of Example 1 before and after staining with pure stains at 20°C. The test results are shown in Table 3. Table 3: Results of visual and spectrophotometric evaluation of single and repeated washing performance of Example 1 on selected stains Visual assessment Spectrophotometric assessment Stains One wash Multiple washes One wash Multiple washes Mixed oil 4.0 4.5 4.5 50 Sunflower oil 4.0 4.5 4.5 5.0 Corn oil 4.0 4.5 4.5 5.0 Sesame oil mixed with soybean oil 3.0 4.0 4.0 4.5 The results of visual and spectrophotometric evaluation presented in Table 3 clearly show that repeated washing of fabrics at 20°C is much easier and more effective than single washing. The dirt release polymer improves the hydrophilicity and wettability of synthetic fabrics by forming a membrane on their surfaces, which helps to remove dirt and oil stains. Therefore, the more washing processes with the composition containing the dirt release polymer, the better the cleaning performance of the composition will be. B. Whitening Cleaning performance: Comparative washing results of the compositions of Examples 2, 3, 4 and Example 7 on selected stains The cleaning performance of the detergent composition can be achieved by combining the bleaching agent and bleach activators, the ratio of which is also very important. To find out the effective ratio of bleaching agent to bleach activator, Examples 2, 3, 4 and 7 (which have different ratios) are compared under the same conditions and the washing performance of the compositions (as Scheffe values) are shown in Table 4. The fabrics are cleaned at 40°C with these compositions. Table 4: Scheffe values ​​comparing the washing results of the compounds of Examples 2, 3, 4 and Example 7 on selected stains Stains Example 2 vs. Example 7 Example 3 vs. Example 7 Example 4 vs. Example 7 Tea 0.50 0.81 1.81 Coffee -0.31 0.44 0.88 Wine 0.31 0.81 2.25 Pomegranate 0.13 0.31 1.50 Cherry 0.56 0.69 1.44 Overall 0.24 0.61 1.58 The Scheffe evaluation results shown in Table 4 clearly show that the higher the ratio of bleaching agent to bleach activator, the better the cleaning performance. Since the composition of Example 7 has more bleaching agent than bleach activator, it shows effective cleaning performance at 40°C. Cleaner containing dirt release agent: Comparative washing results with the combination of Example 1 and Example 8 on selected stains The effect of the soil release polymer on the cleaning performance of the composition was determined by mixing this polymer into a composition having an effective ratio of bleaching agent to bleach activator. Therefore, Examples 1 and 8 are used for comparison. Both examples have the same ratio of bleaching agent to bleach activator, but only Example 1 contains the soil release polymer. Fabrics were cleaned using both compositions at 40°C. The compositions of Examples 1 and 2 were compared under similar conditions and the washing performance of these compositions (as Scheffe values) is shown in Table 5. Table 5: Comparative Scheffe values ​​of washing results with the combination of Example 1 and Example 8 on selected stains Stains Example 8 vs. Example 1 Tea 1.50 Coffee 1.56 Wine 1.75 Pomegranate 0.69 Cherry 0.44 Overall 1.19 The Scheffe evaluation results presented in Table 5 clearly show that fabrics are cleaned more effectively using the composition of Example 1 (which contains a soil release polymer) and at a temperature of 40°C than Example 8. The composition of Example 1 increases the cleaning effectiveness and performance of the composition because the soil release polymer forms a membrane on the surfaces of synthetic fabrics, increasing their hydrophilicity and wettability, which removes soil and oily stains. C. Brightness Brilliant performance: Comparative wash results with the compositions of Examples 5, 6, 7 and 8 After rinsing and drying the fabrics, the brightening performance of the cleaning composition was determined spectrophotometrically. The fabrics were cleaned at 40°C. To obtain the effective amount of photobleach for sufficient brightening, Examples 5, 6, 7 and 8 are used for comparison because these compositions contain different amounts of photobleach. Test 6: Spectrophotometric evaluation of luminescence for the compounds of Examples 5, 6, 7 and 8 Spectrophotometric Evaluation Examples Example 5 75 Example 6 79 Example 7 73 Example 8 79 The results of spectrophotometric evaluation of the luminance performance presented in Table 6 clearly show that Example 7 has the lowest luminance due to the absence of photobleach. Example 5 provides lower luminance than Examples 6 and 8 because it contains a lower amount of photobleach. Example 6 and Example 8, although they have different amounts of photobleach, show the same luminance. This is because excessive use of photobleach does not produce a detectable change after a few moments due to saturation. Cleaner containing dirt release agent: Comparative washing results with a combination of Examples 1 and 8 The effect of the dirt release polymer on the brightness of the composition was determined by mixing this polymer into a composition containing an effective amount of photobleach. Examples 1 and 8 were used for comparison. Both examples had equal amounts of photobleach but only Example 1 contained the dirt release polymer. The compositions of Examples 1 and 8 were compared under similar conditions and the brightness performance of the compositions was determined spectrophotometrically and is shown in Table 7.
