Definitions

  • This invention relates to pouched compositions which comprise an alkoxylated compound.
  • Another method of minimising the contact between detergent and consumer is to 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.
  • 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.
  • 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.
  • a composition 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.
  • 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;
  • an alkoxylated compound having an average alkoxylation degree of at least 50, preferably at least 80 is provided to improve the cleaning performance of a detergent composition in wash water comprising water- soluble film material, in particular polyvinyl alcohol.
  • the pouch of the invention is typically a closed structure, made of a water-soluble film described 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 prior 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 characteristics required from the pouch to hold, protect and deliver or release the compositions.
  • the 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 ofthe wash load.
  • 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.
  • 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 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%.
  • the thickness and hence the degree of stretching is non-uniform over the pouch, due to the formation and closing process.
  • 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.
  • 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 ofthe mould.
  • 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.
  • 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.
  • 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%.

  • 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.
  • 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 300,000, preferably around 150,000.
