Definitions

  • the present invention relates to pouch compositions and an oral pouched nicotine product according to the claims.
  • a further challenge in the prior art is that the desired release of nicotine should be attractive to the user of the pouch from a user perspective.
  • pouches as delivery vehicle for nicotine may be somewhat costly and thereby impose restrictions on the way pouches are designed in order to keep manufacturing costs in check.
  • the product comprises a filling material comprising a particulate non-tobacco material, a nicotine source, 1-15 wt% water, a pH adjusting agent selected from Na2C03, K2C03, NaHC03 and/or KHC03, as well as a salt of Formula M 2+ (A n- ) m , wherein the M 2+ is selected from Ca 2+ , Mg 2+ , Mn 2+ , Zn 2+ and Fe 2+ .
  • the particulate non-tobacco material may comprise sugar alcohol.
  • the filling material may comprise water insoluble fiber.
  • the nicotine source may be a nicotine salt and/or nicotine base.
  • the nicotine source such as nicotine base may be bound to an ion exchange resin.
  • the pouch contains a matrix composition comprising a combination of nicotine and a water-soluble composition.
  • the present invention relates to a pouch composition
  • a pouch composition comprising
  • One advantage of the present invention may be that a relatively high stability of the provided nicotine may be obtained, while at the same time obtaining a relatively fast nicotine release. Obtaining a high stability may lead to nicotine being bound too effectively e.g. to a carrier and therefore lead to slow release.
  • the claimed pouch composition including combination of a water content of at least 15% by weight of the composition and divalent inorganic cations, a high stability yet fast release is facilitated, while also having a very desirable mouthfeel and taste.
  • the high water content facilitates effective release of nicotine during use.
  • One advantage of the invention is that a relatively fast release rate of nicotine from the pouch composition may be obtained due to the presence of the divalent cations. At the same time a desirable moist mouthfeel is provided, due to the high water content, which also facilitate fast nicotine release.
  • the invention may advantageously provide a more effective release of nicotine during use of a pouch comprising the pouch composition. Obtaining an effective release of nicotine may enable a lower total dose of nicotine with the same amount of nicotine released, due to a minimization of any residual nicotine not released from the pouch composition.

  • the amount of divalent cations should advantageously be high enough to enable ion-exchange of the complexed nicotine for the divalent cations during use of a pouch comprising the pouch composition.
  • the amount of inorganic divalent cations may even prevent exchanged nicotine from re-complexing with the ion-exchange resin during use.
  • the amount of inorganic divalent cations may decrease the probability of any uncomplexed nicotine, such as free base nicotine and/or exchanged nicotine from complexing/re-complexing with the ion-exchange resin during use.

  • Example 9A User evaluation.
  • the produced pouches of the invention were evaluated and found highly suitable as delivery vehicles of nicotine in that they provide a favorable release of nicotine and at the same time are pleasant to the user, e.g. with respect to a desirable mouthfeel such as a moist and moldable texture and a desirable taste.
  • Example 9B User evaluation.
  • the pouch product P03 and P44 was evaluated with respect to perceived effect from nicotine and mouthfeel.
  • Perceived effect from nicotine and mouthfeel was evaluated by a test panel of 4 trained assessors. Each assessor evaluates all samples twice. Average evaluations are estimated.
  • the pouch product P03 and P44 were evaluated to have a fast onset of action and a high perceived effect from nicotine by all four assessors. Also, all four assessors evaluated the pouch products to have a desirable mouthfeel, i.e. the pouches were found to be moist and have a desirable taste.
  • the pouches, P08 and P127 were evaluated. These pouches were evaluated to have a fast onset of action and a high perceived effect from nicotine by all four assessors. However, the pouches were found to provide a less desirable mouthfeel, the pouches being perceived as somewhat dry, adhering to the oral mucosa and/or as having a poor taste or less desirable taste, i.e. too salty.
