Technical field The present invention relates to an article of manufacture and in particular to an article of manufacture comprising: a container; a set of instructions; and a liquid bleaching composition comprising a peroxygen bleach inside said container.

Background of the invention Bleach-containing compositions for treating fabrics are well known in the art.

Peroxygen bleach-containing compositions have been extensively described in the art, especially in laundry applications as laundry additives and/or laundry pretreaters.

Indeed, it is known to use such peroxygen bleach-containing compositions in laundry applications to boost the removal of dried on (encrusted) stains/soils and "problem"stains, such as grease, coffee, tea, grass, mud/clay-containing soils, which are otherwise particularly difficult to remove. In addition, peroxygen bleaches are safe to fabrics, specifically to dark colored fabric items, in particular when compared to other bleaches, as for example hypohalite bleaches.

Nevertheless, peroxygen bleaching compositions are considered by the users of such compositions as damaging dark colored fabric items treated therewith. Indeed, the users of said compositions consider said compositions to cause color damage ("discoloration") of dyed fabric items treated with said compositions, in particular dark colored fabric items.

On the contrary, it is submitted that bleaching compositions comprising a peroxygen bleach show an excellent color safety performance. Indeed, such

bleaching compositions show an excellent color safety performance when used on dark colored fabric items and even on black fabric items. Moreover, it has been observed that bleaching compositions comprising a peroxygen bleach reduce or even prevent color bleeding when used to treat colored fabric items.

Hence, it is not just that such bleaching compositions do not show a negative effect regarding color safety when treating dark colored fabric items but there is even the beneficial effect of color bleeding reduction or even prevention when treating dark colored fabric items.

It is therefore an objective of the present invention to provide a user of a bleaching composition comprising a peroxygen bleach with a suitable way of treating dark colored fabric items.

It has now been found that this objective can be met by an article of manufacture according to the present invention comprising: a container; a set of instructions to treat dark colored fabric items; and a liquid bleaching composition comprising a peroxygen bleach, wherein said container contains said liquid bleaching composition. Furthermore, the objective can be met by the method of instructing the public according to the present invention and the method of promoting the use of liquid bleaching composition according to the present invention.

Advantageously, the bleaching compositions as described herein also provide excellent bleaching performance. More particularly, the compositions of the present invention provide excellent bleaching performance when used as a laundry additive and/or a laundry pretreater.

A further advantage of the bleaching compositions according to the present invention is that they are able to perform in a variety of conditions, i. e. , in hard and soft water as well as when used neat or diluted.

Typically an effective amount of liquid bleaching composition in neat condition is an amount that provides from 25 to 100 grams, preferably from 30 to 75, and more preferably from 40 to 60 grams of peroxygen bleach per kilogram of dry fabric.

By"treating a fabric", it is meant herein cleaning said and/or bleaching/disinfecting said fabric.

In the process of treating (e. g., cleaning and/or bleaching) a fabric, a bleaching composition according to the present invention is contacted with the fabrics to be treated.

This can be done either in a so-called"pretreatment mode", where a liquid bleaching composition, as defined herein, is applied neat onto said fabrics before the fabrics are washed or in a"soaking mode"where a liquid bleaching composition, as defined herein, is first diluted in an aqueous bath and the fabrics are immersed and soaked in the bath, before they are washed, or in a"through- the-wash mode", where a liquid bleaching composition, as defined herein, is added in addition to a wash liquor formed by dissolution or dispersion of a conventional laundry detergent, preferably in a washing machine.

More specifically, the pretreatment process of bleaching fabrics according to the present invention preferably comprises the steps of first contacting said fabrics with a bleaching composition according to the present invention, then allowing said fabrics to remain in contact with said composition, for a period of time sufficient to bleach said fabrics, then rinsing said fabrics with water before being washed.

The bleaching composition may be used in dilute or neat form. Where it is used diluted, the bleaching composition should remain in contact with the fabric for typically 1 to 60 minutes, preferably 5 to 30 minutes. Whereas, when the bleaching composition is used in its neat form, it should remain in contact with the fabric for a much shorter time, typically 5 seconds to 30 minutes, preferably 1 minute to 10 minutes.

In the process herein, said fabrics are to be washed, i. e. , treated with a conventional laundry detergent, preferably comprising at least one surface active agent, the washing of said fabrics with a conventional laundry detergent may be conducted before the step of contacting said fabrics with said bleaching composition and/or during the step of contacting fabrics are contacted with said bleaching composition and/or after the step where said fabrics are contacted with the bleaching composition.

In a preferred embodiment, the washing of said fabrics with a conventional laundry detergent is conducted before the step of contacting said fabrics with said bleaching composition and/or during the step of contacting fabrics are contacted with said bleaching composition. More preferably, he washing of said fabrics with a conventional laundry detergent is conducted before the step of contacting said fabrics with said bleaching composition. Indeed, it has been observed that bleaching said fabrics with the compositions according to the present invention (diluted and/or neat bleaching processes) prior to washing them with a detergent composition provides superior whiteness and stain removal with less energy and detergent than if said fabrics are washed first, then bleached.

In a preferred embodiment according to the present invention, the conventional laundry detergent as described herein are dissolved or dispersed, preferably substantially dissolved or dispersed, in the aqueous bath formed in the process according to the present invention. By"substantially dissolved or dispersed"it is meant herein, that at least 50%, preferably at least 80%, more preferably at least 90%, even more preferably at least 95%, still more preferably at least 98%, and most preferably at least 99%, of said conventional laundry detergent are dissolved or dispersed in the aqueous bath formed in the process according to the present invention.

In a preferred embodiment, the washing step according to the present invention is performed in a washing machine. The conventional detergent composition may be delivered into the washing machine either by charging the dispenser drawer of the washing machine with the detergent or by directly charging the drum of the washing machine with the detergent.

By"conventional laundry detergent"it is meant herein, a laundry detergent composition currently available on the market. Preferably, said conventional laundry detergent comprises at least one surface active agent ("surfactant"as described herein below). Said laundry detergent compositions may be formulated as powders, liquids or tablets. Suitable laundry detergent compositions are for example DASH futur@, DASH essential@, DASH liquid@, ARIEL tablets@ and other products sold under the trade names ARIELE or TIDES.

Preferably, the instructions concerning the use of the liquid bleach composition are in consumer-friendly language on packaging and/or in advertising (e. g., leaflets, coupons, displays, etc.). By'consumer-friendly language', it is meant that consumers would be instructed how to use the product to achieve the best results. It is important that the instructions are as simple and clear as possible and it is envisioned that pictures, drawings and/or icons can be used, either with or without words to render the instructions more consumer-friendly. The set of instructions can be multi-lingual to be more easily understood by consumers who speak different languages. Special packaging design can also be advantageously used to convey instructions in a consumer-friendly fashion.

The units of measurement provided to consumers will reflect consumer understanding, e. g. , English dosing units will be preferred in, e. g. , the United States and the United Kingdom, and metric units will be used in, e. g. , most European nations. Although all of the compositions and methods described herein are written in metric units, it is understood that these units will be converted into consumer-friendly language instructions in the actual product packaging, advertising etc. Furthermore, the effective levels needed of the essential and optional actives are expressed herein as the amounts of the actives per weight of fabrics, the instructions for use to the consumer will be expressed as amount per use of the liquid bleach composition, when a preferred composition is set.

Peroxygen bleach-containing compositions in laundry applications are known to boost the removal of dried on (encrusted) stains/soils and"problem"stains, such as grease, coffee, tea, grass, mud/clay-containing soils, which are otherwise particularly difficult to remove. In addition, peroxygen bleaches are safe to

fabrics, specifically to dark colored fabric items, in particular when compared to other bleaches, as for example hypohalite bleaches.

Nevertheless, peroxygen bleaching compositions are mistakenly considered by the users of such compositions as having the tendency of damaging dark colored fabric items treated therewith. Indeed, the users of said compositions consider said compositions to cause color damage ("discoloration") of dyed fabric items treated with said compositions, in particular dark colored fabric items.

It has been found that bleaching compositions comprising a peroxygen bleach show an excellent color safety performance. Indeed, such bleaching compositions show an excellent color safety performance when used on dark colored fabric items and even on black fabric items.

Moreover, it has been observed that bleaching compositions comprising a peroxygen bleach reduce or even prevent color bleeding when used to treat colored fabric items. Indeed, the dyes of dark colored fabric items when contacted with aqueous compositions, such as a laundry wash solution formed by water and a conventional laundry detergent, have the tendency to dissolve of the fabric and go in solution. It has been observed that such solubilised dyes tend to deposit themselves on other parts of the fabric items treated and therefore change the coloration of said fabric items. This effect is known as'color bleeding'.

Without being bound by theory, it has now been found that the peroxygen bleach herein is capable of neutralizing/discoloring, i. e., bleaching, such dissolved fabric dyes in situ, i. e. , in the laundry wash solution. Thereby, the color bleeding is significantly reduced or even prevented in case a liquid bleaching composition forming part of the article of manufacture as described herein is used as directed by the set of instructions as described herein.

Hence, it is not just that the bleaching compositions herein do not show a negative effect regarding color safety when treating dark colored fabric items but there is even the beneficial effect of color bleeding reduction or even prevention when treating dark colored fabric items.

A set of instructions as described herein is essential to obtaining the benefits of the present invention because users of bleaching compositions comprising a

peroxygen bleach are unaware of the benefits provided as described herein.

More specifically, such used are not aware that the use of said liquid bleach composition can safely and effectively bleach and/or remove stain from colored fabric, including dark and/or black colored fabric, without causing damage or significantly reducing the damage to the color of said colored fabric. As such, a set of instructions provided in association with the liquid bleach composition is essential for the consumer to enjoy the benefits of the present invention.

A further advantage of process herein is the cleaning performance. In fact, the cleaning performance benefits of the combination of both the liquid bleaching composition and the conventional laundry detergent is greater than the performance provided by either composition alone.

Method of instructing the public The present invention further encompasses a method of instructing the public by providing to the public a set of instructions for use of an article of manufacture comprising a container; and a liquid bleaching composition comprising a peroxygen bleach ; wherein said set of instructions comprises instructions to contact dark colored fabric items with said liquid bleaching composition in its neat or diluted form and wash said dark colored fabric items in an aqueous bath comprising water and a conventional laundry detergent before and/or during and/or after the step of contacting said dark colored fabric items with said liquid bleaching composition.

Preferably, the term'the public'has to be interpreted in a way to mean an unconfined or unrestricted group or mass of people forming at least part of the whole population of a country or a state or a city as opposed to the confined circle of people defined by one person's family or friends. In a preferred embodiment herein, the method herein is directed at instructing the bleach-using part of the public as defined herein. By'bleach-using part of the public'it is meant herein that part of the population of a country or a state or a city that usually uses a bleaching composition in their laundry washing operations.

Suitable silicones for use herein include any silicone and silica-silicone mixtures.

Silicones can be generally represented by alkylated polysiloxane materials while silica is normally used in finely divided forms exemplified by silica aerogels and xerogels and hydrophobic silicas of various types. These materials can be incorporated as particulates in which the silicone is advantageously releasably incorporated in a water-soluble or water-dispersible, substantially non-surface- active detergent impermeable carrier. Alternatively, the silicone can be dissolved or dispersed in a liquid carrier and applied by spraying on to one or more of the other components.

Actually in industrial practice, the term"silicone"has become a generic term, which encompasses a variety of relatively high-molecular-weight polymers containing siloxane units and hydrocarbyl groups of various types. Indeed, silicone compounds have been extensively described in the art, see for instance US 4 076 648, US 4 021 365, US 4 749 740, US 4 983 316, EP 150 872, EP 217 501 and EP 499 364. The silicone compounds disclosed therein are suitable in the context of the present invention. Generally, the silicone compounds can be described as siloxane having the general structure : R #

wherein n is from 20 to 2000, and where each R independently can be an alkyl or an aryl radical. Examples of such substituents are methyl, ethyl, propyl, isobutyl, and phenyl. Preferred polydiorganosiloxanes are polydimethylsiloxanes having trimethylsilyl end blocking units and having a viscosity at 25°C of from 5 x 10-5 m2/s to 0.1 m2/s, i. e. , a value of n in the range 40 to 1500. These are preferred because of their ready availability and their relatively low cost.

A preferred type of silicone compounds useful in the compositions herein comprises a mixture of an alkylated siloxane of the type herein above disclosed and solid silica.

The solid silica can be a fumed silica, a precipitated silica or a silica made by the gel formation technique. The silica particles can be rendered hydrophobic by treating them with diakylsilyl groups and/or trialkylsilane groups either bonded directly onto the silica or by means of silicone resin. A preferred silicone compound comprises a hydrophobic silanated, most preferably trimethylsilanated silica having a particle size in the range from 10 mm to 20 mm and a specific surface area above 50 m2/g. Silicone compounds employed in the compositions according to the present invention suitably have an amount of silica in the range of 1 to 30% (more preferably 2.0 to 15%) by weight of the total weight of the silicone compounds resulting in silicone compounds having an average viscosity in the range of from 2 x 10-4m2/s to 1m2/s. Preferred silicone compounds may have a viscosity in the range of from 5 x 10-3m2/s to 0. 1m2/s. Particularly suitable are silicone compounds with a viscosity of 2 x 10-2m2/s or 4.5 x 10- 2m2/s.

Suitable silicone compounds for use herein are commercially available from various companies including Rhone Poulenc, Fueller and Dow Corning.

Examples of silicone compounds for use herein are Silicone DB@ 100 and Silicone Emulsion 2-3597@ both commercially available from Dow Corning.

Typically preferred silicone compounds are described in European Patent application EP-A-573699. Said compositions can comprise a silicone/silica mixture in combination with fumed nonporous silica such as Aerosil0.

Antioxidant The bleaching compositions according to the present invention may further comprise an antioxidant.

Typically, the bleaching compositions herein may comprise up to 10%, preferably from 0.002% to 5%, more preferably from 0.005% to 2%, and most preferably from 0.01 % to 1 % by weight of the total composition of an antioxidant.

Suitable antioxidants to be used herein include organic acids like citric acid, ascorbic acid, tartaric acid, adipic acid and sorbic acid, or amines like lecithin, or aminoacids like glutamin, methionine and cysteine, or esters like ascorbil palmitat, ascorbil stearate and triethylcitrate, or mixtures thereof. Preferred antioxidants for use herein are citric acid, ascorbic acid, ascorbil palmitat, lecithin or mixtures thereof.

Bleach activator As an optional ingredient, the compositions of the present invention may comprise a bleach activator. By"bleach activator", it is meant herein a compound, which reacts with hydrogen peroxide to form a peracid. The peracid thus formed constitutes the activated bleach. Suitable bleach activators to be used herein include those belonging to the class of esters, amides, imides, or anhydrides.

Examples of suitable compounds of this type are disclosed in British Patent GB 1 586 769 and GB 2 143 231 and a method for their formation into a prilled form is described in European Published Patent Application EP-A-62 523. Suitable

examples of such compounds to be used herein are tetracetyl ethylene diamine (TAED), sodium 3,5, 5 trimethyl hexanoyloxybenzene sulphonate, diperoxy dodecanoic acid as described for instance in US 4 818 425 and nonylamide of peroxyadipic acid as described for instance in US 4 259 201 and n- nonanoyloxybenzenesulphonate (NOBS). Also suitable are N-acyl caprolactams selected from the group consisting of substituted or unsubstituted benzoyl caprolactam, octanoyl caprolactam, nonanoyl caprolactam, hexanoyl caprolactam, decanol caprolactam, undecenyl caprolactam, formyl caprolactam, acetyl caprolactam, propanoyl caprolactam, butanoyl caprolactam pentanol caprolactam or mixtures thereof. A particular family of bleach activators of interest was disclosed in EP 624 154, and particularly preferred in that family is acetyl triethyl citrate (ATC). Acetyl triethyl citrate has the advantage that it is environmental-friendly as it eventually degrades into citric acid and alcohol. Furthermore, acetyl triethyl citrate has a good hydrolytical stability in the product upon storage and it is an efficient bleach activator. Finally, it provides good building capacity to the composition.
