- a soiled garment is treated by applying an effective amount of the spot pretreatment composition directly at the location of a stain and optionally onto the surrounding area ofthe stain.
- an effective amount of the spot pretreatment composition directly at the location of a stain and optionally onto the surrounding area ofthe stain.
- One way is simply by means of manually dispensing an effective amount ofthe spot pretreatment composition directly from a container or vessel directly to the location ofthe stain. To make such a manual application convenient for the consumer, a number of devices may be used.
- the spot pretreatment composition may be provided in a spray bottle having a manually operated pump, squeeze bottle, aerosol, or other dispensing container.
- a spray bottle having a manually operated pump, squeeze bottle, aerosol, or other dispensing container.
- Such containers are known to the art.
- localized application ofthe spot pretreatment composition is facilitated and simplified by the requisite operation ofthe pump ofthe spray bottle, or by squeezing the squeeze bottle to dispense an amount ofthe spot pretreatment composition, or by spraying the cleaning composition from the pressurized aerosol container containing the composition according to the invention.
- a further particularly useful, known art dispensing apparatus is that of a container having a liquid permeable applicator tip or end, such as a porous sponge or porous fabric applicator tip.
- a removable cap covering the applicator tip is withdrawn, the container inverted to allow the flow ofthe container's contents to impregnate the permeable applicator tip and the tip is then manually contacted with the stain to both transfer an amount of the spot pretreatment composition, and at the same time to manually agitate or abrade the textile or garment at the locus ofthe stain and optionally in the surrounding region.
- Such manually applied agitation provides a mechanical action which acts to physically break up the stain. This is particularly useful for stains which have been left untreated for an extended period of time, i.e., days, weeks, and longer periods, and may have hardened.
- Such manual agitation provides in addition to the mechanical loosening ofthe stain, further acts to improve the penetration ofthe spot pretreatment composition throughout and among the stained fibers. Such mechanical action also improves the overall stain removal characteristics ofthe spot pretreatment composition. Due to these beneficial characteristics, containers having a liquid permeable applicator tip or end is particularly preferred, and such containers are known to the art.
- a soiled garment is treated by applying an effective amount ofthe spot pretreatment composition directly at the location of a stain and optionally onto the surrounding area ofthe stain, and subsequent to such application, a disposable absorbent sheet, or another part ofthe garment or other garment to manually agitate and "rub in” the spot pretreatment composition so to ensure that it is thoroughly distributed amongst the stain and the fibers at the locus ofthe stain.
- a disposable absorbent sheet may be produced from any fibrous or cellular flexible material which exhibits good abso ⁇ tion ofthe spot pretreatment composition.
- such sheets may be non-woven materials such as those which have adhesively bonded fibers in a web accorded fiber structure and/or those which comprise fibrous mats in which the fibers are distributed in a random array.
- a fibrous can be naturally produced fibers including wool, silk, cotton, linen, hemp, sisal, ramie or may be synthetically produced such as synthetically spun fibers of polymers.
- synthetic fibers include rayon, cellulose, polyvinyl derivatives, polyolefins, polyesters, as well as polyamides. Of course, mixtures of two or more different fibers may be used in the production of such non- woven materials.
- Such sheets are sufficiently strong such that they will resist tearing or separation when used to manually agitate the stain treated with the spot pretreatment compositions as taught in this specification.
- These sheets when used, may be of any dimension but are preferably sheets having an area of at least two square centimeters but are preferably ones having greater areas. Sheets having larger areas, i.e., those having areas of at least 50 square centimeters and greater are preferred from the view point of ease of use and handling.
- the spot pretreatment compositions may be provided in measured amounts impregnated in a disposable absorbent sheet as described above.
- the spot pretreatment composition may be simultaneously provided to an end consumer with said sheet, and the consumer is then required to impart mechanical force to the locus ofthe stain on the garment in order to dispense the spot pretreatment composition thereto.
- the simultaneous provision of an amount ofthe spot pretreatment composition simultaneously with the mechanical force imparted to both apply the composition and break up the stain may be supplied.
- a further advantage of such a mode of application is that the absorbent nature ofthe sheet also acts as a substrate to entrain the loosened stain and remove it from the garment.
- Such impregnated disposable absorbent sheets are readily prepared and easily packaged by known art methods.
- sheets may be impregnated with the spot pretreatment composition by dipping, spraying, coating, pressure treating, vacuum filling or other known method for applying the liquid to the absorbent sheet, and subsequently packaging said sheets into a liquid tight packaging container.
- liquid tight packaging containers may be of any type known to the art, including rigid liquid tight vessels and containers, single opening or resealable bags or pouches, and the like. Of particular mention are single opening pouches which are intended to be torn open by an end consumer, and the absorbent sheet impregnated with the spot pretreatment composition removed in a ready to use form.
- the stains on garment or textiles are treated with the spot cleaning compositions as described above in a "pre-treatment" step, which is subsequently followed by a laundering or dry cleaning step.
- a laundering step is conventionally known to the art and contemplates the immersion ofthe garments or textiles in an aqueous wash bath which desirably includes an amount of a detergent composition.
- a dry cleaning step may be one presently conventionally known to the art, as is typically practiced by conventional dry cleaning establishments, such as on a commercial scale.
- An alternative dry cleaning process may be one which is practiced by a consumer in a home or domestic environment, such as is described in one or more ofthe patents indicated above, but preferably is one which is practiced utilizing the liquid cleaning compositions particularly useful as a home dry cleaning composition.
- a particularly advantageous liquid cleaning composition which may be used following pretreatment of a garment or textile with the spot pretreatment compositions according to the present invention comprises the following constituents: 0.01 - 5%wt. (preferably 0.01 - 2.5%wt. ) nonionic surfactant which is preferably an alkoxylated primary or secondary alcohol and/or an alkoxylated phenol; 0.01 - 2.5%wt.
- anionic surfacant selected from alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkylamide sulfosuccinates, alkyl sulfosuccinamates, as well as salt forms thereof; 0 - l%wt. (preferably 0 - 0J%wt. ) fluorosurfactant constituent including one or more of those which may be present in the spot cleaning composition; 0.01 - 7%wt. organic solvent selected from alcohols and glycol ethers especially water miscible alcohols and ethers, to 100% wt. of water, and further up to about 2% wt. (preferably 0 - l%wt.
- these liquid cleaning compositions are aqueous in nature and comprise about 90%wt. and more of water.
- Such a liquid cleaning composition is advantageously applied to the surface of a garment or textile, particularly at the location ofthe stains which had been treated utilizing the spot cleaning compositions being taught herein in order to provide a further cleaning effect to the treated garment or textile. They are particularly useful when applied to the surface of a garment or textile which is being tumbled in a vapor permeable or vapor impermeable bag for a sufficient time to generally uniformly wet the garment or textile surface with such a liquid cleaning composition.
- the use of such a laundering or dry cleaning step may in some cases be particularly advantageously practiced as the present inventors have observed that the spot cleaning compositions ofthe invention may leave small amounts of surface residues, or visible rings of a whitish residue at the junction between the dry garment or textile surface and the periphery ofthe wetted area of a treated stain.
- Such laundering or dry cleaning step removes any such residues which may form, but other techniques to minimize the formation of such a residue and/or to remove it may be practiced as well.
- the inventors have found that using an absorbent tipped dispenser in a brush stroking fashion to impart linear strokes minimizes the formation of such a peripheral ring.
- the major portion ofthe spot cleaning composition was supplied to the locus ofthe stain and lesser amounts ofthe spot cleaner were supplied to the edges beyond the stain.
- a "feathered" application ofthe spot cleaning composition was provided. It is to be noted that a circular or swirling application pattern was not applied to the blouse in order to minimize the likelihood of deforming the textile.
- references to "parts by weight” and “weight percent” and “%wt.” are considered to be interchangeable and to represent the weight percent of a particular constituent with reference to a total composition within which it is included, where such total composition is considered to have 100 parts by weight.
- all ofthe constituents of each ofthe formulations described in the examples below are recited in parts by weight and are based on 100 parts by weight of a particular formulation, unless specified to be otherwise. Examples;
- compositions according to the invention were prepared having the constituents which are indicated on Table 1 below wherein the amounts given are the weight percent of each respective constituent.
- the surfactants were added to the stirring water and allowed to become well dispersed prior to the addition ofthe remaining constituents. After the addition of the final constituent, the contents ofthe beaker were allowed to stir for a period of 5 to 15 minutes to ensure homogeneous mixing and the production of a uniform formulation. Each ofthe formulations was observed to be shelf stable for period of weeks and months.

- Example 1 An evaluation ofthe cleaning properties ofthe formulation according to Example 1 (see Table 1) in accordance with the following general protocol: A clean white rayon blouse was stained in several separate locations with a 0.2 gram amount of a liquid make up (COVER GIRL Ultra Finish Creme Makeup (Soft Beige)). The measured amounts ofthe makeup was applied at each separate location, and evenly spread with a spatula to form a test stain. The thus stained rayon blouse was then allowed to set at room temperature for 30 minutes to ensure the absorbence ofthe liquid make up into the fibers ofthe blouse and to approximate actual consumer conditions for use ofthe product, who would be understood as likely using the formulations ofthe invention on stains which have been set and or dried onto a fabric for an interval of time.
- COVER GIRL Ultra Finish Creme Makeup Soft Beige
- an absorbent paper towel sheet was placed on a hard, nonabsorbent surface and a second paper towel sheet was folded twice to form a pad.
- the blouse was placed on the laid out paper towel sheet such that a test stain was laid on top.
- 3.0 gram amount ofthe formulation according to Example 1 was applied directly to the location of a stain using a pipette, and immediately subsequently the folded paper towel pad was used to manually impart forty (40) strokes ofthe pad in a variety of directions so to mechanically agitate the stain on the blouse and to ensure that the formulation was interspersed among the rayon fibers.
- the absorbent paper towel was removed from beneath the stain and both the folded paper towel pad and the absorbent paper towel was inspected. It was noticed that a substantial portion ofthe liquid make up was removed and was now entrained or absorbed on one or both ofthe paper towels.
- the test stain was observed to have been completely removed from the rayon blouse leaving only a wetted circular area resulting from the application ofthe ofthe formulation according to Example 1.
- the surface ofthe rayon blouse was sprayed with a sufficient amount ofthe particularly advantageous liquid cleaning composition described above, and which generally comprised the following constituents: 0.01 - 5%wt. (preferably 0.01 - 2.5%wt. ) nonionic surfactant which is preferably an alkoxylated primary or secondary alcohol and/or an alkoxylated phenol; 0.01 - 2.5%wt.
- anionic surfacant selected from alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkylamide sulfosuccinates, alkyl sulfosuccinamates, as well as salt forms thereof; 0 - l%wt. (preferably 0 - 0J%wt. ) fluorosurfactant constituent including one or more of those which may be present in the spot cleaning composition; 0.01 - 7%wt. organic solvent selected from alcohols and glycol ethers especially water miscible alcohols and ethers, to 100% wt. of water, and further up to about 2% wt. (preferably 0 - l%wt. ) of one or more optional constituents.
- the thus treated rayon blouse was then placed into the interior of a vapor impermeable containment bag, whose opening was sealed to retain the blouse within the interior of said bag, and the containment bag and its contents were supplied to the interior of conventional, horizontally rotating clothes drying apparatus on a "fluff cycle for 5 - 15 minutes. No heat was applied.
- the rayon blouse freely tumbled within the containment bag which was observed to billow and expand, which in turn itself freely tumbled within the rotating drum ofthe dryer apparatus.
- Example 14 Within several minutes after treatment with spot cleaning composition according to Example 14, the surface ofthe rayon blouse was sprayed using a quantity ofthe liquid cleaning composition as taught in copending application described in Example 1 , above.
- the rayon blouse was similarly provided to a containment bag, and subsequently treated as generally described in Example 1.
- Example 15 Following the general protocol and again utilizing the liquid cleaning composition described for Cleaning Example 1, a sample ofthe formulation according to Example 15 (see Table 2) was evaluated for its spot cleaning efficacy on a rayon blouse with the same test stains as in Cleaning Example 1. Following the conclusion ofthe spot cleaning operation, a substantial portion ofthe liquid make up was again noted to have been absorbed upon one or both ofthe paper towel surfaces, and the stain was observed to have been totally removed.
- a clean paper towel sheet was placed on a hard nonabsorbent surface, and a second paper towel was folded over to form a pad therefrom.
- a portion ofthe blouse with the stain facing upwards was placed on the paper towel sheet, and 3 gram sample ofthe formulation according to Example 14 (see Table 2) was applied directly to the stain.
- the paper towel pad was manually stroked 40 times in order to sufficiently rub the formulation into the stain and amongst the fibers ofthe rayon blouse.
- the paper towels were removed from the locus ofthe stain and they were visually inspected. It was observed that all ofthe red lipstick was removed onto one or both ofthe paper towel surfaces and that the white rayon blouse at the location ofthe prior stain was clean and was only wetted by the absorbed formulation.
- the rayon blouse was treated with the liquid cleaning composition and further processed in the manner described in Cleaning Example 1.
- the efficacy ofthe spot cleaning results were observed to be "excellent" as the formulation according to Example 15 essentially removed all ofthe red lipstick stain from the rayon blouse. Also, no whitish rings or "fronts" were observed at the periphery ofthe wetted circular area formed by the formulation after the blouse was allowed to dry.
- Example 14 To the stain, were provided a 3.0 gram sample ofthe formulation according to Example 14 (see Table 2) and immediately after such application the stain was manually rubbed with the paper towel pad fifty (50) strokes in order to mechanically agitate the stain and to ensure the penetration ofthe formulation in to the stain and amongst the rayon fibers. Afterwards, both ofthe paper towels were removed and were visually observed to have essentially entrained thereupon all ofthe liquid make up, and that the stain was essentially completely removed from the rayon blouse.
- Example 14 Within several minutes after treatment with spot cleaning composition according to Example 14, the surface ofthe rayon blouse was sprayed using a quantity ofthe particularly advantageous liquid cleaning composition described above in the specification, as well as in Example 1, above.
- the rayon blouse was similarly provided to a containment bag, and subsequently treated as generally described in Example 1.
- each ofthe fabric swatches was placed with the stains facing upward upon a separate absorbent paper towel laid out upon a flat hard surface, with the swatch approximately centered upon the paper towel.
- To the liquid makeup test stain on an individual fabric swatch using a pipette 0.2 grams ofthe formulation according to Example 16 (see Table 2) was dispensed directly onto the stain. Shortly thereafter, a second paper towel folded twice to form an absorbent pad was used to manually rub the stain with 40 strokes after which the folded paper towel pad was removed and observed visually.
- Example 16 a 2.0 gram sample ofthe formulation according to Example 16 was applied to the tomato sauce stain on the same swatch and using a second folded paper towel likewise folded to form an absorbent pad, the formulation was rubbed into the stain using 40 strokes and again, the pad was removed and observed.
- This protocol was repeated for each ofthe fabric swatches until the formulation according to Example 16 was used to clean both ofthe stains on each ofthe four swatches evaluated.
- the rayon swatch is designated to be Cleaning Example 8
- the silk swatch is designated to be Cleaning Example 9
- the polyester/cotton blend swatch is designated to be
- Cleaning Example 10 and the wool swatch is designated to be Cleaning Example 11.
- each of these individual cleaning results were judged to be "excellent”. Afterwards, each ofthe swatches was sprayed using a quantity ofthe particularly advantageous liquid cleaning composition and described in Example 1, above. The swatches were similarly provided to a containment bag, and subsequently treated as generally described in Example 1.
- each ofthe paper towels were observed to have entrained thereupon substantially all ofthe test stains from each ofthe fabric swatches, and each ofthe stains on each ofthe fabric swatches was observed to have been substantially removed.
- Each of these individual cleaning results were judged to be "excellent"
- each ofthe swatches was sprayed using a quantity ofthe particularly advantageous liquid cleaning composition described in Example 1, above. The swatches were similarly provided to a containment bag, and subsequently treated as generally described in Example 1.
- a formulation according to the invention namely a formulation according to Example 16 (Table II) was evaluated in conjunction with the following protocol.
- a clean white rayon blouse was laid on a flat surface, and a 3.0 gram sample ofthe formulation according to Example 16 was dropped on to the middle of one ofthe sleeves using a pipette to form a circle of wetted rayon.
- the formulation was worked into the sleeve by stroking it approximately 40 times thus to ensure the complete interspersal ofthe formulation amongst the fibers ofthe blouse. This is allowed to sit for several minutes after which was applied over the complete surface ofthe sleeve a "post-treatment" formulation having the following composition:
- This "post treatment” formulation was applied on the surface ofthe sleeve particularly in the region ofthe area wetted by the formulation of Example 16 using a finger pumpable trigger spraying device in sufficient amounts wherein the sleeve showed light but uniform wetting- Afterwards, the thus treated rayon blouse was inserted into a large white polyethylene bag and the open end sealed. Immediately afterwards, the bag was inserted into the interior of a conventional, horizontally rotating clothes drying apparatus and the dryer was operated on a "low” setting for 30 minutes after which the dryer was stopped and the contents ofthe bag withdrawn.
- the cleaning evaluation of a formulation according to the invention was evaluated as against two commercially available formulations.
- the first commercially available formulation was SHOUT a laundry pre-treatment product currently marketed by SC Johnson & Co., Racine WI and was designated "Comparative Formulation I”.
- the second commercially available formulation, SPRAY 'N WASH a further laundry pre-treatment product currently marketed by
- Example 16 It was observed that the formulation according to Example 16 was observed to be the fastest acting of the three formulations tested as it most quickly and thoroughly remove the stain compared to either ofthe commercially available, SHOUT and SPRAY 'N WASH compositions. Further, it was observed that subsequent to drying, for the polyester cotton swatches, visible stain fronts were retained by both the SHOUT and SPRAY 'N WASH compositions, whereas the stain was completely removed by the formulation according to Example 16.
- Cleaning Examples 18. 19 Comparative Cleaning Examples TTT. IV
- the cleaning efficacy of two spot cleaning compositions according to the invention, one at an acidic pH, the other at an alkaline pH were compared against two different prior art spot cleaning compositions.
- the composition of Cleaning Example 18 was at a pH of 10.5, in an "as is" spot cleaning formulation of Example 21.
- the composition of Cleaning Example 19 was a spot cleaning formulation according to Example 21 which was adjusted using an minor amount of an acid to a pH of 5.0.
- the first comparative composition indicated as "Comparative Cleaning Example III” was an aqueous hydrogen peroxide preparation of 1-5% H 2 O 2
- a further “Comparative Cleaning Example IV” was a liquid composition extracted from a commercially available product believed to be in accordance with the formulations indicated in U.S. Patent No. 5,238,587.
- PET-cotton fibers were stained with amounts ofthe following: 0.3 grams lipstick, 0.2 grams of a liquid make up composition, 0.5 grams of spaghetti sauce, 0.5 grams of salad dressing, 0.25 grams mayonnaise, 0.25 grams mustard, 0.20 grams coffee, a ball point pen ink composition, ten strokes of a cosmetic blush composition, 0J5 grams olive oil, and 0.20 grams of a red wine. In each case, these materials were applied individually to the individual swatches and allowed to age for 24 hours in an undisturbed state.
- Wool and rayon swatches were stained only with lipstick, make up, blush, pehn ink, mayonaise and coffee stains.
- Blended fiber swatches of polyethylene terephthalate - cotton (PET- cotton) and silk were stained with each ofthe staining compositions noted above.
- each of these stained swatches was treated with one of two spot cleaning compositions, either that according to Ex.21 or a prior art which was extracted from a commercially available product believed to be in accordance with the formulations indicated in
- each ofthe individual-swatches was treated using 3 grams of one ofthe spot cleaning compositions indicated above. Each of these individual formulations was applied using a porous applicator tip inserted on the top of a small plastic bottle which contained a quantity ofthe particular spot cleaning composition. Each ofthe tested spot cleaning compositions were readily absorbed and passed through this porous applicator tip, which was used to apply the spot cleaning composition by supplying 50 circular rubs with the porous applicator tip at the location ofthe stain on each individual swatch.
- the spot cleaning compositions ofthe invention are excellent, not only as spot cleaning compositions useful for stains which are "fresh”, but perhaps even more significantly are excellent spot cleaning compositions for "aged" stains for a wide variety of textile substrates.
