- a fabric treatment applicator comprising an application device and a fabric treatment composition, the fabric treatment composition comprising a radical scavenger and a chelating agent.
- a fabric treatment composition comprising a radical scavenger and a chelating agent for no rinse fabric treatment.
- a fabric treatment applicator comprising a fabric treatment composition which comprises a chelating agent and a radical scavenger and preferably also a bleach. While the addition of a chelating agent and a radical scavenger have been found to increase the cleaning performance of the fabric treatment applicator also in absence of a bleach, they further have been found to be useful to stabilise the bleach. Most preferably the fabric treatment composition comprises a bleach and a surfactant as specified hereinafter.
- a fabric treatment composition according to the present invention can be used and applied in any manner, the composition is preferably applied with an applicator described hereinafter and most preferably with an applicator comprising a nib.
- the fabric treatment composition according to the present invention allows for no rinse single step fabric treatment even on delicate fabrics. Preferred methods of use are also further described hereinafter.
- compositions comprising a radical scavenger and a chelating agent and which can be used for fabric treatment are within the scope of the present invention.
- fabric friendly compositions in particular stain removal compositions as described below.
- Rinsing refers to a post-treatment step following the stain removal step as part of one fabric treatment procedure.
- rinsing encompasses rinsing as part of a washing-cycle in a washing machine, rinsing as part of a hand-washing procedure after treatment with a washing detergent (which may comprise a bleach) and rinsing after treatment with a bleach, e.g. by soaking a whole garment. While a whole garment may be subjected to rinsing, rinsing may also be a localised treatment of only a portion of a garment.
- No rinse fabric treatment refers to fabric treatment without any of the above mentioned rinsing steps.
- Preferred fabric treatment methods according to the present invention work well without that a whole garment is subjected to rinsing, but even more preferred fabric treatment methods do work well without any localised post-treatment with any fluid, e.g. treatment with a moist cloth and any localised application of water, a solvent and the like. Most preferred no rinse
- Preferred fabric treatment compositions are compositions which do not leave visible residues on a treated fabric when the fabric is not rinsed. Residues are considered not visible, when they receive a rating of less than 2.5 panel score unit in the Residue Test Method described below. Preferred no rinse fabric treatment composition afford a rating of less than 1.5, more preferably less than 1.0, yet more preferably less than 0.5 panel score units.
- the preservation of bleach comprised by the fabric treatment composition is particularly critical for avoiding dye removal.
- chelating agents and in particular the chelating agents listed herein are helpful in stabilizing bleaches and in particular oxygen based bleaches.
- the chelating agents may not fully prevent the disintegration of bleaches, but that the presence of radical scavengers, and preferably the radical scavengers listed herein, helps to inactivate disintegrated components of bleaches , which are believed to be mostly radicals, and to block the propagation of bleach decomposition, and hence to prevent fabric damage or dye removal by such disintegrated bleach components.
- the preservation of the bleach is also critical to avoid gas build-up inside the fabric treatment applicator.
- Chelating agents and radical scavenger are believed to prevent the bleach from decomposing into water and oxygen gas, which therefore reduces the risk of gas build-up and possible oxidation of parts of the fabric treatment applicator. Oxidation is particularly critical for metal parts of the applicator. Metal parts may be present in the application device or in flow interruption means, such as a valve comprising a metal spring. Moreover the gas-build up itself may affect the controlled delivery of the fabric treatment composition or may even become a safety hazard.
- While the fabric treatment compositions disclosed herein may have very different pH values, an acidic pH value is preferred, a very preferred pH range being from 4 to 6, most preferably 4.5 to 5.5. It is believed that the preferred pH values help to stabilize bleach by preventing its decompostion, and therefore further hence to prevent fabric damage.

- Other complexes which may be included herein are those of U.S. Application Ser. No. 08/210,186, filed March 17, 1994.
- a stain removal composition comprising a radical scavenger and a chelating agent and preferably a bleach is efficient in treating a large variety of stains. It is known that various greasy stains are best treated with a surfactant whereas other common stains such as from grass, tomato sauce or wine are best treated with bleach, while water soluble stains can normally effectively removed with water.
- compositions disclosed herein may also favourably be used in other contexts, for example for bleaching and/or sanitation of non-stained fabrics.
- any applicator comprising a fabric treatment composition and an application device is within the scope of the present invention.
- Preferred applicator according to the present invention comprise an application device which induces a certain friction upon the fabric, on which it is to be used. This largely helps efficient removal of a stain.
- the application device is a device which in use is in contact with the surface on which the fabric treatment applicator is used and delivers the fabric treatment composition to that surface.
- Preferred application devices include any felt, non-woven material, sponge, or foam insert, for example in the form of a porous pad, and most preferably in the form of a nib.
- Another preferred application device is a roller ball.
- Other preferred application devices are all those used to apply a writing fluid to paper, e.g. as used in a fountain pen.
- the whole wipe or towelette is encompassed by the term application device.
- the fabric treatment composition is provided in solid stick form, the whole solid stick is encompassed by the term application device. Applicators having only one application device, most preferably a nib are preferred.
- the frictional stress value is defined as the force exerted upon a reference fabric per unit area of real contact and is measured as given below.
- the frictional stress of an application device is of particular importance as it is an indicator of the efficiency with which the mechanical energy provided by the user is transferred to the fabric to abrade a stain and/or deliver the fabric treatment composition onto and into any chosen area of the fabric.
- an application device is inefficient, as indicated by a low frictional stress value, the energy supplied by the user is dissipated in other ways, for example, through the application device itself deforming or tearing.
- Frictional stress of an application device ⁇
- F the frictional force
- A the contact area
- ⁇ the coefficient of friction
- R the reaction to the normal load.
- Frictional stress values as measured in the method detailed below, of greater than 0.05 N mm -2 have been shown to be advantageous, more preferably the frictional stress values are from 0.05 N mm -2 to 10 N mm -2 , yet more preferably from 0.1 N mm -2 to 1 N mm -2 and most preferably from 0.2 N mm -2 to 0.4 N mm -2 .
- Preferred applicators comprise a housing comprising a reservoir for the storage of a composition.
- a housing may be a bottle of any shape or size.
- Preferred shapes for such housings are hollow barrel shapes, most preferably having a diameter to length ratio from 1:30 to 1:2, so as to be convenient to hold in the user's hand, use and store. More preferred are housings of a diameter to length ratio from 1:20 to 1:5, which resemble in shape a pen, e.g. a ball pen or a highlighter pen, and which are herein referred to as pen-shaped.
- the reservoir may be filled with an absorbent material, such as a wadding or a cartridge style device such as those commonly found in ink pens able to release liquid on demand.
- the housing may be made of any solid material, which may also be flexible, such as glass or any plastic material. A preferred material is polypropylene.
- the application device is preferably comprised by the housing, most preferably one application device is comprised, most preferably a nib.
- the application device is also in liquid communication with the reservoir, which allows for the most convenient delivery of the fabric treatment composition to the application device.
- the reservoir for the fabric treatment composition is provided in the form of a replaceable cartridge.
- Such nib typically is a fibre-tip nib as commonly found in children's colouring pens or highlighting pens.
- a nib according to the present invention does preferably not comprise a single opening or channel to deliver the fabric treatment composition.
- Such an opening or channel does not allow for very controlled delivery of the fabric treatment composition.
- insufficient composition will be delivered for effective cleaning or unnecessary large amounts of composition may be delivered, the latter leading to longer drying times for the treated fabric or in some cases possibly even to residues.
- an opening or channel leading to the reservoir promotes the evaporation of volatile compounds of the composition stored therein and may further induce leaking when the fabric treatment applicator is transported.
- the same disadvantages are associated with a porous application device.
- a nib in accordance with the present invention preferably has a pore size of less than 300 ⁇ m.
- pores which may be present in a nib according to the present invention have a size from 1 ⁇ m to 200 ⁇ m, more preferably from 5 ⁇ m to 100 ⁇ m, more preferably from 10 ⁇ m to 50 ⁇ m.
- the nib has a pointy shape, most preferably being cone- or wedge-shaped.
- a cone-shaped nib allows to exert pressure on a relatively narrow area, as beneficial for mechanical stain removal, without leading to damage of the nib, which is thicker and hence more stable closer to the housing.
- a cone- or wedge-shaped nib also allows the fabric treatment composition to be applied to a small selected area as beneficial for low moistening of the fabric and low residues.
- the nib should be in contact with the reservoir directly or indirectly so as to allow transfer of the fabric treatment composition to the nib during use.
- the nib may be made of any synthetic or man-made or natural materials such as felt, open cell foam, closed cell foams, polyethylene, nylon etc.
- a preferred material for the nib is felt, most preferably provided from synthetic fibres.
- the nib while being held by the housing has a section external to the housing, this section preferably measures from 3.0 cm to 0.1 cm, more preferably from 1.0 cm to 0.25 cm, most preferably from 0.75 cm to 0.5 cm in length.
- the contact area - measured as given below - between the application device and a flat surface preferably is from 0.25mm 2 to 400mm 2 , more preferably from 1mm 2 to 100mm 2 , most preferably from 4mm 2 to 10mm 2 . Such a contact area ensures optimal mechanical stain removal and allows for application of the fabric treatment composition to small selected areas.
- Preferred application devices according to the present invention also exhibit a certain delivery volume efficiency - measured as described below.
- the delivery volume efficiency is defined as the amount of fluid (ml) delivered to the fabric per unit time per unit area (s -1 mm -2 ).
- the right delivery volume efficiency ensures that a sufficient but not too high amount of fabric treatment composition is delivered giving the benefits of a sufficient and constant flow rate and further the benefit of avoiding drying out of the nib (10) or the reservoir in between uses.
- the delivery volume efficiency is preferably from 0.0005 ml mm -2 s -1 to 0.1 ml mm -2 s -1 and more preferably from 0.001 ml mm -2 s -1 to 0.01 ml mm -2 s -1 .
- the applicator may also comprise a cap to prevent evaporation of the composition and to prevent any unattended contact of the application device with objects when not used.
- any applicator with any composition disclosed herein will depend on the applicator itself and also on the object on which the applicator is to be used.
- compositions disclosed herein are intended for usage on any surface of a material in direct or indirect contact with the human body, which inter alia are all encompassed by the term fabric.
- Those surfaces are typically soft surfaces comprised by materials such as soft plastic materials, leather and textile fabrics. Textile fabrics namely are found in clothing, including shirts, ties, blouses, socks, skirts, trousers, jackets, underwear, watch straps etc.
- compositions can be used on fabrics comprised by carpets, curtains or upholstery and the like.
- a fabric treatment applicator comprising a housing and an application device
- the cap covering the application device if present, is removed before application.
- the application device is then brought into contact with a selected area of an fabric.
- exertion of pressure may be needed to release the composition from the applicator.
- the pressure initially needed for this purpose may be higher than the pressure needed to ensure constant the flow of the composition.
- Wiping or otherwise moving the application device over the selected application area may also be required to deliver the composition to all parts of this area and may help to uniformly apply the composition. Rubbing, i.e. wiping while exerting pressure towards the fabric, may help in the mechanical removal of stains.
- the application of any composition disclosed herein may be one step of a more comprehensive treatment of a fabric.
- the treatment may for example comprise preparing steps, such as removing larger amounts of a stain inducing material, e.g. food, with a serviette or the like.
- a stain removal treatment carried out with an applicator according to the present invention does not comprise a rinsing step for the removal of a stain.
- a rinsing step is not needed, since the fabric treatment applicators disclosed herein are highly efficient in removing any stains, including water soluble ones.
- post-treatment of a fabric under running water or with a moist cloth is not required - neither as not to lease residues nor for mechanical removal of a stain - due to the effective mechanical removal of any stains by means of the disclosed application device and the residue free and fabric friendly treatment by the chemical compositions used.
- an additional step such as a drying step is normally not needed, since the compositions disclosed herein promote quick drying and the applicators disclosed herein allow application of low amounts of a fabric treatment composition to small areas.
- swatches of fabric are individually dyed with a dye from a representative dye category such as from reactive dyes, sulphur dyes, vat dyes, direct dyes and azoic dyes.
- a swatch of fabric is prepared with a dye from each category.
- a measured area within each swatch is treated with the fabric treatment composition and allowed to dry. Any dye removal in the treated swatch is assessed visually by comparing the treated area of the swatch with the surrounding untreated area of the swatch.
- the application device is clamped to the load arm of a Plint dual axis reciprocating rig (such as model TE75R, MRPRA RUBBER CONSULTANTS).
- the angle of the fabric treatment applicator relative to the contact surface is adapted to maximise the contact area. Angles of the fabric treatment applicator relative to the contact surface for which the angle between the vertical axis of the fabric treatment applicator (a line connecting the centre of the contact area with the centre of mass of the fabric treatment applicator defines the vertical axis.) and the contact surface less than 45° are not considered (since they are not typical for a consumer preferred application method).
- the clamping arrangement provided a consumer realistic vertical load, R, on the application device of 3N.
- the coefficient of friction is then measured between the application device and a 100% cotton fabric as used in mens' shirts mounted on soft counter surface provided by a 2 mm thick sheet of soft rubber mounted with double sided adhesive to a flat aluminium plate.
- the application device is measured wet using a composition as given in Example 1.
- the coefficient of friction is measured over the central 10 mm of four traverses of 20 mm in both the forward and reverse direction at a speed of 1 mm s -1 and an average value calculated. Measurements with the application device in final measuring position are repeated three times to check reproducibility.
- Measurements of the contact area of the application device are carried out with a fabric treatment applicator which contains a dry application device and no treatment composition.
- the dry application device is inked by pressing it against an ink stamp pad and then clamping the fabric treatment applicator to the load arm of a Plint dual axis reciprocating rig (such as model TE75R, MRPRA RUBBER CONSULTANTS).
- a mark on a contact surface which is representative of the contact area of the application device is obtained by controlled lowering and raising of the Plint load arm towards and away from the contact surface.
- the angle of the fabric treatment applicator relative to the contact surface is adapted to maximise the contact area.
- Angles of the fabric treatment applicator relative to the contact surface for which the angle between the vertical axis of the fabric treatment applicator (as defined above) and the contact surface less than 45° are not considered (since they are not typical for a consumer preferred application method).
- the contact time should be approximately 1s while a 3N load should be applied on the application device.
- the contact area can then be calculated from the mean length and width of the mark determined using a magnifying lens with a graticule. Measurements with the application device in final measuring position are repeated three times to check reproducibility.
- the application device is firmly inserted through the bottom of a standard liquid container (such as a 50ml centrifuge tube available from Coming No. 25330-50).
- a standard liquid container such as a 50ml centrifuge tube available from Coming No. 25330-50.
- the size of the orifice through which the application device is inserted is cut to the size of the application device and a silicone based sealant used.
- This unit is then clamped into position beneath a compressor unit (such as a Lloyd LR5K Compression meter).
- This arrangement provides a consumer realistic vertical load of 3N.
- the application device is placed in contact with an absorbent pad comprised of a bicomponent synthetic fibre top layer above a fluffy pulp base layer. The pad allows rapid transport away from the point of delivery so as not to reduce the concentration gradient and hence reduce flow.
- the container is then filled with the stain removing solution (such as Example 1) to a level of 20 ml.
- the amount of fluid that flows per unit time is measured by noting the loss of fluid from the reservoir over a fixed period.
- the delivery volume efficiency is then calculated by normalising the flow rate with respect to the total surface area of contact (mm 2 ) between the application device and the fabric. Measurements are repeated three times to check reproducibility.
