Definitions

  • the present disclosure relates to a smokeless article.
  • the disclosure relates to a smokeless article comprising nicotine-dosed bamboo fibres, wherein the bamboo fibres have a particle size of 10-500 ⁇ m.
  • Smoking is generally considered to expose a smoker to potentially harmful substances. It is generally thought that the majority of the potentially harmful substances are formed by the heat generated during burning (combustion) of the article. There is interest in so-called heat not burn products, which heat a tobacco or similar substrate at a lower temperature than a conventional cigarette. These products are usually described as less harmful than conventional cigarettes. Both conventional cigarettes and heat not burn products are visible during use and produce smoke or vapour.
  • Smokeless articles are a suitable alternative because they do not require heating for substance delivery to the user. Instead, smokeless articles rely on saliva to extract soluble substances, typically nicotine and/or flavours, from tobacco contained within the smokeless article.
  • Conventional smokeless articles have a saliva permeable pouch housing a content.
  • the content is generally in the form of tobacco, said tobacco containing a soluble element, typically nicotine.
  • a product may be referred to as portion snus. It is typically provided as prepackaged (traditionally moist) powder in small teabag-like pouches. Each pouch is a single portion or unit. This moistened product may be referred to as original snus.
  • Smokeless articles are placed in the mouth where saliva extracts the soluble element from the tobacco contained within.
  • the smokeless article is placed in the oral cavity, sublingually or in the oral vestibule (between the teeth and lips/cheeks).
  • the user may assist extraction by oral manipulation, such as by chewing and/or sucking or pressing on the outside of the mouth to squeeze the pouch.
  • the resulting saliva which contains extracts, subsequently contacts a mucous membrane in the mouth, or at another point of the gastrointestinal tract, to deliver the soluble element across the membrane and into the bloodstream.
  • the soluble element is then transported by the bloodstream to the site of action. For example, nicotine is delivered to the brain where it acts upon acetylcholine receptors.
  • Snuff is smokeless tobacco made from ground or pulverised tobacco leaves. Snuff is available in dry form or wet (moist) form. Moist snuff may be referred to as snus. Two common varieties of snus are Scandinavian snus and American snus. Both varieties of snus are available in a loose form, but are often contained within a saliva permeable pouch.
  • snus is typically manufactured by grinding a blend of leaf tobaccos to specified particle sizes.
  • the ground tobacco is then mixed with water and sodium chloride in closed process blenders.
  • the mixture is subjected to a heat treatment, involving temperatures up to 80 - 100 °C, for several hours to pasteurize the snus. Thereafter, the snus is cooled and other ingredients may be added.
  • Snus is typically manufactured to meet the GothiaTek® standard, as detailed in " Swedish snus and the GothiaTek® standard” (2005), Rutqvist , et al.
  • the present disclosure relates to a smokeless article e.g. a snus article for oral use.
  • a smokeless article for oral consumption comprising a pouch enclosing a content, the content comprising nicotine-dosed bamboo fibres, wherein the bamboo fibres have a particle size of 10-500 ⁇ m.
  • a smokeless article comprising bamboo fibres of a particle size within this range provides an unexpectedly high nicotine release rate from the article.
  • a higher nicotine release rate provides a more effective product which is more desirable to some consumers.
  • the bamboo fibres provide the product with a paler appearance which increases the eye appeal of the product to consumers.
  • the bamboo fibres have a particle size of 10-450 ⁇ m, for example 10-400 ⁇ m, 10-350 ⁇ m, 10-300 ⁇ m, 10-250 ⁇ m, 10-200 ⁇ m, 10-150 ⁇ m, 10-100 ⁇ m, 10-50 ⁇ m, 15-50 ⁇ m, 15-45 ⁇ m, 20-50 ⁇ m, 20-45 ⁇ m, 20-40 ⁇ m or 25-35 ⁇ m. In some embodiments, the bamboo fibres have a particle size of about 30 ⁇ m.
  • the bamboo fibres have a particle size of 15-500 ⁇ m, for example 20-500 ⁇ m, 50-500 ⁇ m, 100-500 ⁇ m, 150-500 ⁇ m, 200-500 ⁇ m, 250-500 ⁇ m, 250-450 ⁇ m, 250-400 ⁇ m, 250-350 ⁇ m, 260-340 ⁇ m, 270-330 ⁇ m, 280-320 ⁇ m, 290-310 ⁇ m or 295-305 ⁇ m. In some embodiments, the bamboo fibres have a particle size of about 300 ⁇ m.
  • the bamboo fibres have a particle size of 30-300 ⁇ m.
  • the nicotine-dosed bamboo fibres comprise a nicotinic compound selected from nicotine, nicotine salt(s), nicotine complex(es); and nicotine solvate(s).
  • the nicotinic compound is provided in a plant material.
  • the plant material is tobacco.
  • the smokeless article is tobacco-free.
  • the user may experience a similar or enhanced recreational/pharmaceutical effect as compared to conventional tobacco-containing products without experiencing undesirable components inherent to tobacco (e.g. tobacco flavour).
  • tobacco flavour undesirable components inherent to tobacco
  • the total nicotine content is from 5 to 15 mg. In some embodiments, the total nicotine content is about 10 mg.
  • greater than 75 wt%, preferably greater than 80 wt%, of the total nicotine content of the smokeless article is released from the smokeless article after 20 minutes immersed in water.
  • Another aspect of the invention is the use of nicotine-dosed bamboo fibres, wherein the bamboo fibres have a particle size of 10-500 ⁇ m, as a nicotine release accelerant in a smokeless article for oral consumption.
  • the smokeless article is according to the first aspect.
  • Another aspect of the invention is the use of nicotine-dosed bamboo fibres, wherein the bamboo fibres have a particle size of 10-500 ⁇ m, to increase manufacturing capacity of a smokeless article and/or reduce manufacturing cost.
  • the smokeless article is according to the first aspect.
  • bamboo fibres of a relatively small particle size in the range 10-500 ⁇ m means that the particulate bamboo fibre feedstock has a higher bulk density than a corresponding bamboo fibre feedstock of a larger particle size. This means that during manufacture of the product, the feedstock occupies a smaller volume and a larger mass of fibres may be processed per unit time. This increases manufacturing capacity, reducing the overall production cost for the product and increasing efficiency of the manufacturing process.
  • a further reduction in manufacturing cost and increase in efficiency is achieved by the smokeless article of the invention due to the higher density of the bamboo fibre feedstock.
  • the higher density means that the pouch may be smaller while still carrying the same mass of fibre. This means that the amount of material used to manufacture the pouch per smokeless article is reduced, which reduces manufacturing cost.
  • a second aspect of the invention is a process of manufacturing the smokeless article according to the first aspect, comprising the steps of;
  • Another aspect of the invention is a kit comprising a plurality of smokeless articles according to the first aspect and a container.
  • particle size when referring to fibres such as bamboo fibres indicates the maximum size of the longest dimension of the fibres. For example, a particle size of 50 ⁇ m indicates that in the population of fibres, the maximum fibre length is 50 ⁇ m.
  • Particles having the desired particle size may be obtained by passing a population of fibres through a sieve of corresponding mesh size. For example, to obtain fibres of particle size 300 ⁇ m (i.e. a maximum fibre length of 300 ⁇ m), a population of fibres are passed through a sieve with 300 ⁇ m diameter apertures in the mesh. In this way, fibres with a length of 300 ⁇ m or less pass through the mesh and fibres longer than 300 ⁇ m are retained by the mesh. The fibres which pass through the mesh may then be used in the smokeless article of the invention, having a particle size of 300 ⁇ m. Fibres of a desired particle size are also available from commercial suppliers such as Jelu-technik.

Sample 1 contained the following components: Ingredient Content / g Nicotine ditartarate dihydrate 1.40 Bamboo fibres (30 ⁇ m) 56.02 Salt 4.20 Water 30.00 Ammonium chloride solution 2.03 Propylene glycol 3.65 Sodium carbonate solution 0.41 Flavour (mint) 2.30 Total 100
  • Sample 2 One further sample, Sample 2, was prepared which contained bamboo fibres with a maximum length of 300 ⁇ m (JELUCEL® BF-300 fibres ex Jelu-werk).
  • Sample 2 contained the following components: Ingredient Content / g Nicotine ditartarate dihydrate 1.40 bamboo fibres (300 ⁇ m) 56.02 Salt 4.20 Water 30.00 Ammonium chloride solution 2.03 Propylene glycol 3.65 Sodium carbonate solution 0.41 Flavour (mint) 2.30 Total 100
  • Comparative Sample 1 was Skruf #3, a commercially available smokeless article which includes wheat fibres with a maximum particle size of 200 ⁇ m.
  • Comparative Sample 2 was Lyft #3, a commercially available smokeless article which includes eucalyptus and pine fibres.
  • the samples were tested by immersing each of the samples in the same model solution representing human saliva.
  • the model solution was made with deionised water containing the following ingredients: Ingredient Content (g/1000mL) Magnesium chloride hexahydrate 0.17 Potassium hydrogen phosphate anhydrous 0.68 Sodium chloride 0.33 Potassium chloride 0.75 Calcium chloride dehydrate 0.15 Potassium carbonate 0.53 Hydrochloric acid to pH 6.8 ⁇ 0.1
  • the model solution was prepared by mixing all ingredients in the table except hydrochloric acid and transferring to a 2 L glass reservoir. 500 mL of deionised water was added and the solution was mixed well to dissolve. Further deionised water was added to bring the total amount of deionised water added to 1 L. The reservoir was sealed and mixed well. The pH was then adjusted to 6.8 by the addition of HCI. The solution was used within 2 days of preparation.
  • Nicotine concentration in the model solution was determined at certain time intervals by UV-vis using USP 4 flow-through dissolution apparatus with online UV system, thereby providing an indication of the rate of release of nicotine from the immersed pouch.
  • Figure 5 is a plot showing the results of nicotine release tests for the smokeless articles of the invention and the comparative articles.
  • Samples 1 and 2 demonstrated significantly improved nicotine release characteristics over the comparative articles.
  • Sample 1 containing 30 ⁇ m fibres more than 80 wt% of the nicotine content was released after 20 minutes, compared with only around 45-60 wt% for the comparative articles.
  • Sample 2 containing 300 ⁇ m fibres more than 90 wt% of the nicotine content was released after 20 minutes.
