Definitions

  • the present invention relates to a printed water-soluble package including a bittering agent, in particular, packages containing dishwashing or laundry detergent compositions, methods of producing such packages and their use in dishwashing or textile laundering.
  • Water-soluble packages known in the art typically include a composition, such as a dishwashing or laundry detergent composition enclosed in a water-soluble film, container or capsule.
  • the detergent composition can therefore be released from the water-soluble package on exposure to water during use.
  • Such water-soluble packages provide the advantages of providing single dosing packages, the user does not need to open the package and the user is not exposed to the detergent composition before use.
  • the contents of such water-soluble packages must be released quickly and completely during use in water, and without leaving a residue.
  • the water- soluble package is often a thin water-soluble film package or a thin walled water-soluble capsule or container, and may have a high water solubility or reactivity.
  • water-soluble package may be relatively fragile.
  • the water- soluble package may be susceptible to damage from environmental moisture.
  • the structural integrity of the water-soluble package may be weakened and/or the water- soluble packages may have a tendency to stick together when a number of the packages are stored in close proximity over a period of time.
  • WO 02/26896 and JP/0129438 describe water-soluble package materials which are coated with a fine powder. Suitable powders include calcium carbonate, magnesium carbonate, clay, talc, silicic acid and kaolin. Such coating is said to provide excellent slip and anti-blocking properties.
  • WO 2013/158364 describes a water-soluble packet comprising a water- soluble film coated by a powder wherein the powder comprises a mixture of powdered lubricant and an active agent.
  • the combination of a powdered lubricant and an active agent is reported to be particularly advantageous in providing the packet with additional functionality while improving the feel of the packet surface, mitigating potential weeping of liquid products onto the surface of the packet, and preventing the packets from sticking together, thereby preventing possible failure during separation.
  • the powdered lubricant is said to be typically a starch, modified starch, silica, siloxane, calcium carbonate, magnesium carbonate, clay, talc, silicic acid, kaolin, gypsum, zeolite, cyclodextrin, calcium stearate, zinc stearate, alumina, magnesium stearate or zinc oxide.
  • the active agent is typically one or more of enzymes, oils, flavours, colorants, odour absorbers, fragrances, pesticides, fertilisers, activators, acid catalysts, metal catalysts, iron scavengers, bleaches, bleach components or fabric softeners.
  • EP 0 700 989 A1 describes a unit packaged detergent for dish washing which may include an additive which provides an unbearable bitter taste, such as denatonium (e.g. bitrexTM).
  • the additive may be coated onto the unit package detergent in order to improve the prevention that children may accidently ingest the package detergent.
  • WO 2008/034594 A1 and EP 2 196 531 A1 describe coated detergent compositions, including a water-soluble coating. Both documents note that the unit coated detergent can include a coating of an unbearable bitter tasting additive, either as part of the water- soluble coating or as a separate layer.
  • WO 2014/026856 A1 identifies that when the bittering agent is included in a water-soluble film at higher doses, the bittering agent can be transferred to a user's hands when handling the water-soluble film, thus leaving bitterness on the user's hands for several hours. Accordingly, WO 2014/026856 A1 describes a water-soluble package containing an agent and a water-soluble covering wherein the water-soluble covering contains a bittering agent in a diluted state in order to solve this problem.
  • water-soluble packages often include printed information, such as text and/or pictures visible on an exterior surface of the package, in order to show the nature of the contents, to provide any instructions and/or warn of any potentially hazardous materials, for example.
  • a water-soluble film material is printed with one or more dye or pigment layers on to the material using an ink, before adding a protective or lacquer layer on top of the primer and ink or pigment layers.
  • the water-soluble film material is printed with a primer layer first, then printed with the ink. The printed water-soluble material may then be used to form a printed water-soluble package enclosing a composition or material, such as a detergent composition.
  • the present inventors investigated ways of improving printed water-soluble packages and, in particular, into including a bittering agent in a printed water-soluble package.
  • the present inventors have surprisingly discovered that containing a bitter agent within or film-coated on a water-soluble substrate has adverse effects on the appearance of the printed matter on the exterior surface of the water-soluble substrate.

  • a printed region or regions has one or more layers of dye deposited on the exterior surface of the water-soluble substrate.
  • the layer or layers of dye may be deposited directly or indirectly on the exterior surface of the water-soluble substrate.
  • the printed region may include one or more primer layers between the layer of dye and the exterior surface of the substrate.
  • the printed region may include a protective or lacquer layer on top of the layer or layers of dye.
