  • this application relates to the specific compositions in order to fulfill all the said requirements and the needs in this particular field.
  • polyester fibers offer improved abrasion resistance and crease resistance to the garments compared to fabrics woven only from cotton.
  • polyester and polyester blended fabrics are hydrophobic in nature which makes their laundering difficult since polyester and polyester blended fabrics have tendency to retain oily soils and stains which are also hydrophobic in nature.
  • the laundering of oily soils and stains from the surfaces of fabrics woven from polyesters is very challenging and difficult even after repeated laundering because polyester fibers have tendency to absorb and accumulate hydrophobic oily stains and soils.
  • the former approach is associated with finishing process of fibers or fabrics in which fabrics or fibers are treated at once with soil release polymer to improve their hydrophilicity.
  • this approach looks like a right solution, the use of higher amount of soil release polymer during fabric finishing makes the fabrics stiffer. Thus, fabrics lose their softness and desirable appearance.
  • hydrophilicity of the fabrics are diminished due to the removal of soil release polymers either after repeated laundering process or after severe laundering conditions like high temperature, high pH or detersive ingredients. As a result of this, the hydrophilicity of fiber and fabrics tends to decrease gradually which leads to inefficient cleaning and laundering of oily soil and stains.
  • the latter approach is associated with the use of laundry detergents involving soil release polymers which increases the hydrophilicity and wettability of the fabrics via on-going soil release benefit after each laundering.
  • Soil release polymers are textile assistants and washing aids in detergency, having the ability to form films around polyesters fibers to impart soil repellent properties to the surfaces of the fabrics woven from polyesters.
  • soil release polymers Through the use of laundry detergents involving soil release polymers, attachment of oily soil and stains are hindered which renders the soiled fabric susceptible to effective cleaning operation.
  • Soil release polymers are superior washing aids compared to laundry detergent surfactants and builders since they (i)improve water absorptivity (hydrophilicity) of fabrics thus, giving wear comfort and (ii) provide outstanding improvement in the cleaning performance via the detachment of oily soil from the surface of polyester fabrics that could not be achieved just by using ordinary detergent ingredients, (iii) foster multi-wash effect in which the cleaning performance of the fabrics are improved via repetitive launderings since each laundering operation stabilize the soil release polymer amount. But the excess use of soil release polymers makes the fabrics stiffer, harsh and also increases the cost of the laundering process and the increased cost of the operation makes the consumers to change their opinion and preferences.
  • Temperature is also critical for other inevitable ingredients of laundry detergents especially for percompound which is an inorganic peroxide compound, responsible for bleaching, stain and soil removal through the release of hydrogen peroxide by dissolving in water. Their activity is temperature dependent and show effective bleaching performance at temperatures higher than 60°C which is not favorable in terms of cost, energy and textile care considerations. Because of that the utilization of bleach activators are required to enhance the bleaching performance of hydrogen peroxide based detergents at temperatures below 60°C. However, this combination could not show efficient performance of the removal of oil soils and stains at cold or warm wash temperature.
  • the terms used to refer to the cleaning performance of white fabrics are whiteness and brightness which are responsible for the overall efficient whiteness of white fabrics.
  • Whitening is used to refer to the removal of soils and stains during laundering process
  • brightening is used to refer to the deposition of optical brighteners on the fabrics wherein optical brighteners are used to modulate the whiteness perception through the utilization of day light.
  • Optical brighteners deposit on the surfaces of fabrics and mask the discoloration of fabrics and provide a pleasing whiteness to the fabrics.
  • the utilization of optical brighteners and photobleaches would foster the perception of consumers about the performance of cleaning composition.
  • whitening of fabrics is a two stage process such that first stage involves the bleaching of soils and the second stage involves modulation of brightness.
  • the cleaning compositions offer hydrophobic soil removal performance from soiled fabric known from EP2978831 and EP30391 12. However, these compositions could not achieve effective cleaning performance just by the use of soil release polymer. Instead, they needed to incorporate extra ingredients like polyetheramine. These ingredients are providing improved grease removal but the said compositions do not provide bleaching and whitening of the fabrics.
  • the present invention overcomes above mentioned problems by formulating particulate cleaning composition which provides superior bleaching, cleaning and brightening of synthetic fabrics through the synergistic effect of percompound, optical brighteners, photobleach and soil release polymer.
  • the present invention cleaning composition allows the consumer to maintain using the product to its full extent by facilitating a safer, environmentally friendly, effective, and inexpensive cleaning.

  • warm or cold wash water temperatures is used to refer to the washing of fabrics below 40°C washing temperatures.
  • Soil release polymers are employed in cleaning compositions in order to increase the hydrophilicity and wettability of synthetic fabrics by forming films on their surfaces. Soil release polymers are adsorbed on the surface of fabrics during laundering and the water absorption capacity of the fabrics is enhanced which enables the removal of oily soil and stains. Soil release polymers are also mostly prepared by copolymers of moderately high molecular weight, containing ethylene terephthalate segments which are randomly interspersed with polyethylene glycol segments. Soil release polymers can be anionic, nonionic and cationic in nature.
  • Anionic soil release polymers especially containing sulfo groups have good water solubility and thus, efficient soil release performance.
  • the high water solubility of soil release polymers brings about a disadvantage about storage stability. Therefore, the preferred soil release polymers are compatible with additives and auxiliaries customary in detergents and cleaners which are based on polyethyleneterephthalate-polyoxyethyleneterephthalate co-polymers (so-called PET-POET) and they can be supplied under the trade name TexCare® SRA 300 and 300F from Clariant.
  • the amount of soil release polymer is also critical in terms of performance of cleaning process. The utilization of soil release polymer less than 0.1wt.-% does not exhibit soil release and cleaning performance whereas higher than 1 .5wt.-% the performance of the detergent is in saturation but this increases the cost of the process and laundering.

  • Particulate cleaning composition of the present invention ensures on-going and effective bleaching and whitening of hydrophobic fabrics at worm or cold wash water temperatures that can be achieved predominantly by the incorporation of percompounds.
  • Percompounds are oxygen-releasing peroxide compounds which are effective bleaching agents.
  • the preferred bleaching agent for laundering applications involves the use of hydrogen peroxide sources because it not only causes less textile fiber damage compared to many other peroxygen sources but also tends to be less aggressive on fabric, enzymes and optical brighteners.
  • the preferred hydrogen peroxide sources for this invention can be chosen from peroxides and/or persalts.
  • the preferred bleaching source is persalts which could be added to the present invention by selection from the group of perborates (e.g. perborate monohydrate, perborate tetrahydrate), percarbonates, peroxyhydrates, persilicates and persulphates. More preferably, percarbonates are particularly chosen due to (i) their high dissolution rate, (ii) concurrent generation of hydrogen peroxide and carbonate ions which favor the perhydrolysis by maintaining higher pH values.
  • Particulate cleaning composition of the present invention comprises percompound from 3.0wt.-% to 20wt.-%, preferably from 3.5wt.-% to 17wt.-% of the total composition.
  • the preferred percarbonate source for the present invention composition is alkali metal salt of percarbonate. More preferably, sodium salts are preferred. Most preferably, percarbonates are chosen as coated in order to improve their stability.
  • the particulate cleaning composition involves the use of organic bleach activators for percompound since they do not show remarkable activity at lower temperatures.
  • Use of peroxy compounds in combination with activators results in the formation of peroxy acid which is the active species for bleaching. Since the activity of percompound is strongly dependent on temperature, bleach activators are used to activate bleaching agents to function properly at temperatures below 60°C. These bleach activators speed up the bleaching process so that bleaching can effectively take place at temperatures lower than that in the absence of them.
  • the bleach activators are perhydrolyzed to form a peracid as active bleaching species. Bleaching and whitening at warm wash temperatures are very critical in terms of textile care, cost and energy considerations.
  • the suitable bleach activator can be selected from the group of activators such that tetra acetyl ethylene diamine (TAED), nonanoyloxybenzene sulphonate (NOBS), sodium 4-(isononanoyloxy)benzenesulphonate (iso-NOBS).
  • TAED tetra acetyl ethylene diamine
  • NOBS nonanoyloxybenzene sulphonate
  • iso-NOBS sodium 4-(isononanoyloxy)benzenesulphonate
  • the preferred bleach activator for the present invention is tetra acetyl ethylene diamine (TAED).
  • TAED speeds up the bleaching process by reacting with hydrogen peroxide released by sodium percarbonate to produce peroxyacetic acid whose bleaching efficiency is better than hydrogen peroxide, and a molecule of DAED (diacetyl ethylene diamine) which is no longer reactive.
  • Particulate cleaning composition of the present invention comprises bleach activator from 1 .0 wt.-% to 6.0 wt.- %, preferably from 1 .5wt.-% to 5.0 wt.-% of the total composition.
  • the whiteness and bleaching power of particulate cleaning composition of the present invention is fostered with the incorporation of percompound and bleach activators.
  • the utilization of percompound and bleach activators could be considered by their ratio.
  • the utilization of percompound/bleach activator ratio less than 3.0 does not represent any discernible activity and thus, effective bleaching and whitening could not be achieved.
  • the utilization of percompound/bleach activator ratio more than 17.0 could not be economical and also, could not represent effective performance due to either the inefficient activator ratio or the over saturation. Therefore, the ratio of percompound to bleach activator is in between 3.0 and 17.0, preferably in between 3.5 and 15.0.
  • PHOTOBLEACH Bleaching agents other than percompound are also used in particulate laundry detergents in order to enable bleaching of washed fabrics for improving their visual appearance via photophysical mechanisms.
  • Photobleach is also photosensitizer compound which is a molecule that produces a chemical change in another molecule in a photochemical process. When photobleaches absorb light, it becomes excited. While relaxing back to ground state, the energy released oxidizes the ground state oxygen to singlet oxygen which is the effective bleaching agent of photobleaches.
  • Singlet oxygen is an oxidative species which can react with the stains to bleach them. Since stains have chemical and biological background, singlet oxygen reacts with them and distrupt their structure which makes them colorless and mostly water soluble. As a result, stains could be removed.
  • Particulate cleaning composition of the present invention employs sulphonated tetrabenzo- tetraazaporphine derivative. The most common and simplest way of incorporating them into detergent powders is to add them to the slurry prior to spray drying of the base powder.
