Description

2361689 Pouched Composition

Field of Invention 5

This invention relates to pouched compositions which comprise an alkoxylated compound.

Background to Invention 10

The laundry industry has been trying to develop ways that minimise the contact between consumer and detergent product. Such contact includes; contacting the detergent ingredients to the skin of the consumer which can cause irritation to the contacted area, for example causing rashes, blotches, itchiness; and also contacting detergent ingredients in the form of dust, which can become airborne when the product is dosed, to the eyes, nose and even respiratory system of the consumer, causing discomfort to said affected areas.

Another method of minimising the contact between detergent and consumer is to 20 enclose the detergent with a pouch, such as pouches made from a water-soluble film, to form a water-soluble detergent pouch.

The inventors have found that detergents in water-soluble pouches show poor clay stain removal during the washing cycle. Furthermore, the inventors have found that this poor clay stain removal is due to the water-soluble film. It is believed that the water-soluble film cross-links clay present in the wash liquor in such a manner as to redeposit the clay onto the surface of the fabric. This is thought to be especially true when the water-soluble film comprises a hydroxy group, or particularly more than one hydroxy group, such as water-soluble films comprising polyvinyl alcohol. It is believed that the hydroxyl groups are attracted to the surface of certain clays.

2 Moreover, the inventors have found that the addition of specific alkoxylated compounds having an alkoxylation degree of at least 50 to the detergent composition comprised by a water-soluble film solves the problem of poor clay stain removal by detergents in such pouches. Thus, the addition of certain alkoxylated compounds having an alkoxylation degree of at least 50 to a detergent composition comprised by a water-soluble film having a hydroxy group. such as films which comprise a polyvinyl alcohol polymer, improves the clay removal performance of said detergent composition.

Summary of Invention

In a first embodiment of the invention a composition is provided which comprises an alkoxylated compound having an alkoxylation degree of at least 50, wherein the composition is enclosed by a pouch made from a water-soluble film.

In a second embodiment of the invention a process for preparing a composition comprising an alkoxylated compound having an alkoxylation degree of at least 50 and wherein the composition is enclosed by a pouch made from a water-soluble film is provided which comprises the steps; (a) contacting a composition comprising an alkoxylated compound having an average alkoxylation degree of at least 50 to a water-soluble film in such a way as to partially enclose said composition by said water-soluble film to obtain a partially formed pouch;and (b) optionally contacting said partially formed pouch with a second water- soluble film; and (c) sealing said partially formed pouch to obtain a pouch.

In a third embodiment of the invention the use of an alkoxylated compound having an average alkoxylation degree of at least 50, preferably at least 80 is provided to 3 improve the cleaning performance of a detergent composition in wash water comprising water-soluble film material, in particular polvvinyl alcohol.

Detailed Descrij2tion of Invention Pouch and material thereof The pouch of the invention, herein referred to as "pouch", is typically a closed structure, made of a water-soluble film descfibed herein, enclosing a volume space which comprises a composition. Said composition is described in more detail herein. The pouch can be of any form, shape and material which is suitable to hold the composition, e.g. without allowing the release of the composition from the pouch pnor to contact of the pouch to water. The exact execution will depend on for example, the type and amount of the composition in the pouch, the number of compartments in the pouch, the charactefistics required from the pouch to hold, protect and deliver or release the compositions.

T'he pouch may be of such a size that it conveniently contains either a unit dose amount of the composition herein, suitable for the required operation, for example one wash, or only a partial dose, to allow the consumer greater flexibility to vary the amount used, for example depending on the size and/or degree of soiling of the wash load.

It may be preferred that the water soluble film and preferably the pouch as a whole is stretched during formation and/or closing of the pouch, such that the resulting pouch is at least partially stretched. This is to reduce the amount of film required to enclose the volume space of the pouch. When the film is stretched the film thickness decreases. The degree of stretching indicates the amount of stretching of the film by the reduction in the thickness of the film. For example, if by stretching the film, the thickness of the film is exactly halved then the stretch degree of the stretched film is 4 100%. Also, if the film is stretched so that the film thickness of the stretched film is exactly a quarter of the thickness of the unstretched film then the stretch degree is exactly 200%. Typically and preferably, the thickness and hence the degree of stretching is non-uniform over the pouch, due to the formation and closing process.

For example, when a water-soluble film is positioned in a mould and an open compartment is formed by vacuum forming (and then filled with the components of a composition and then closed), the part of the film in the bottom of the mould, furthest removed from the points of closing will be stretched more than in the top part.

Preferably, the film which is furthest away from the opening, e.g. the film in the bottom of the mould, will be stretched more and be thinner than the film closest by the opening, e.g. at the top part of the mould.

Another advantage of using stretching the pouch, is that the stretching action, when forming the shape of the pouch and/or when closing the pouch, stretches the pouch non-uniformly, which results in a pouch which has a non-uniform thickness. This allows control of the dissolution of water-soluble pouches herein, and for example sequential release of the components of the detergent composition enclosed by the pouch to the water.

Preferably, the pouch is stretched such that the thickness variation in the pouch formed of the stretched water-soluble film is from 10 to 1000%, preferably 20% to 600%, or even 40% to 500% or even 60% to 400%. This can be measured by any method, for example by use of an appropriate micrometer. Preferably the pouch is made from a water-soluble film that is stretched, said film has a stretch degree of from 40% to 500%, preferably from 40% to 200%.

The pouch is made from a water-soluble film. It is preferred that the pouch as a whole comprises material which is water-dispersible or more preferably watersoluble. Preferred water-soluble films are polymeric materials, preferably polymers which are formed into a film or sheet. The material in the form of a film can for example be obtained by casting, blow-moulding. extrusion or blow extrusion of the polymer material, as known in the art.

Preferred water-dispersible material herein has a dispersability of at least 50%, preferably at least 75% or even at least 95%, as measured by the method set out hereinafter using a glass-filter with a maximum pore size of 50 microns.

More preferably the material is water-soluble and has a solubility of at least 50%, preferably at least 75% or even at least 95%, as measured by the method set out hereinafter using a glass-filter with a maximum pore size of 50 microns, namely:

Gravimetric method for determining water-solubility or waterdispersability of the material of the compartment and/or pouch:

5 0 grams 0. 1 grain of material is added in a 400 ml beaker, whereof the weight has been determined, and 245n-d Iml of distilled water is added. This is stirred vigorously on magnetic stirrer set at 600 rpm, for 30 minutes. Then, the mixture is filtered through a folded qualitative sintered-glass filter with the pore sizes as defined above (max. 50 micron). The water is dried off from the collected filtrate by any conventional method, and the weight of the remaining polymer is determined (which is the dissolved or dispersed fraction). Then, the % solubility or dispersability can be calculated.

Preferred polymer copolymers or derivatives thereof are selected from polyvinyl alcohols, polyvinyl pyrrolidone, polyalkylene oxides. acrylamide, acrylic acid, cellulose, cellulose ethers, cellulose esters, cellulose amides, polyvinyl acetates, polycarboxylic acids and salts, polyaminoacids or peptides, polyamides, polyacrylamide, copolymers of maleic/acrylic acids, polysaccharides including starch and gelatine, natural gums such as xanthum. and carragum. More preferably the polymer is selected from polyacrylates and water-soluble acrylate copolymers, 6 methylcellulose, carboxymethy1cellulose sodium, dextrin, ethylcellulose, hydroxyethyl cellulose. hydroxypropyl methylcellulose, maltodextrin, polymethacrylates, most preferably polyvinyl alcohols, polyvinyl alcohol copolymers and hydroxypropyl methyl cellulose (HPMC). Preferably, the level of a type polymer (e.g., commercial mixture) in the film material, for example PVA polymer, is at least 60% by weight of the film.

The polymer can have any weight average molecular weight, preferably from about 1000 to 1,000,000, or even form 10,000 to 300,000 or even form 15,000 to 200,000 or even form 20,000 to 150,000.

Mixtures of polymers can also be used. This may in particular be beneficial to control the mechanical and/or dissolution properties of the compartment or pouch, depending on the application thereof and the required needs. For example, it may be preferred that a mixture of polymers is present in the material of the compartment, whereby one polymer material has a higher water-solubility than another polymer material, and/or one polymer material has a higher mechanical strength than another polymer material. It may be preferred that a mixture of polymers is used, having different weight average molecular weights, for example a mixture of PVA or a copolymer thereof of a weight average molecular weight of 10,000- 40,000, preferably around 20,000, and of PVA or copolymer thereof, with a weight average molecular weight of about 100,000 to 3 00,000, preferably around 150,000.

Also useful are polymer blend compositions, for example comprising hydrolytically degradable and water-soluble polymer blend such as polylactide and polyvinyl alcohol, achieved by the mixing of polylactide and polyvinyl alcohol, typically comprising 1-35% by weight polylactide and approximately from 65% to 99% by weight polyvinyl alcohol, if the material is to be water-dispersible, or water-soluble.

7 It may be preferred that the polymer present in the film is from 60-98% hydrolysed, preferably 80% to 90%, to improve the dissolution of the material.

Most preferred are films which are water-soluble and stretchable films, as described above. Highly preferred water-soluble films are films which comprise PVA polymers and that have similar properties to the film known under the trade reference M8630, as sold by Chris-Craft Industrial Products of Gary. Indiana, US.

The water-soluble film herein may comprise other additive ingredients than the polymer or polymer material. For example, it may be beneficial to add plasticisers, for example glycerol, ethylene glycol, diethyleneglycol, propylene glycol, sorbitol and mixtures thereof, additional water, disintegrating aids. It may be useful that the pouch or water-soluble film itself comprises a detergent additive to be delivered to the wash water, for example organic polymeric soil release agents, dispersants, dye transfer inhibitors.

The pouch is made by a process comprising the steps of contacting a composition herein to a water-soluble film in such a way as to partially enclose said composition to obtain a partially formed pouch, optionally contacting said partially formed pouch with a second water-soluble film, and then sealing said partially formed pouch to obtain a pouch.

Preferably, the pouch is made using a mould, preferably the mould has round inner side walls and a round inner bottom wall. A water soluble film may be vacuum pulled into the mould so that said film is flush with the inner walls of the mould. A composition herein may then be poured into the mould, a second water-soluble film may be placed over the mould with the composition and the pouch may then be sealed, preferably the partially formed pouch is heat sealed. The film is preferably stretched during the formation of the pouch.

A sheet of water-soluble film (Chris-Craft M-8630 film) is placed over a cylindricalshaped mould having round sides and bottom and a diameter of 45mm and a depth of 28mm. A I mm. thick layer of rubber is present around the edges of the mould. The mould has some holes in the mould material to allow a vacuum to be applied.

A vacuum is applied to pull the film into the mould so that the film is flush with the inner surface of the mould. 20g of solid detergent composition is poured into the mould so that the mould is filled between 95 % to 100%.

Next, another sheet of water-soluble film (Chris-Craft M-8630 film) is placed over the top of the mould with the solid composition, and is sealed to the first layer of film by applying an annular piece of flat metal of an inner diameter of 46nun and heating that metal under moderate pressure onto the ring of rubber at the edge of the mould to heat-seal the two pieces of film together. The metal ring is typically heated to a temperature of 140-146'C and applied for up to 5 seconds.
