- the edges 15A may be angular edges.
- the cellulose acetate particles 12 do not comprise any edges 15A and/ or corners 15B and, for example, may be spherical.
- the cellulose acetate particles 12 comprise cellulose acetate chips 12.
- the smoking article component 3 allows for the user to control the amount of additive that is introduced into the gas flow passing through the smoking article component 3. Initially, the shell 13 of each additive particle 11 is intact and therefore no additive from the core 14 is introduced into the gas flow.
- the user desires to introduce additive, he or she applies an external force to the smoking article component 3 to rupture the shells 13 of the additive capsules 11.
- the user holds the smoking article component 3 firmly and rolls the smoking article component 3 between his or her fingers. This causes the cellulose acetate particles 12 to rupture the shells 13 of the additive particles 11 such that the additive of the core 14 is released through the shells 13 and enters the gas flow.
- the more that the smoking article component 3 is rolled between the user’s fingers the greater the number of additive capsules 11 that are ruptured and thus the more additive that is released into the gas flow. Therefore, the user is able to control the amount of additive that is added to the gas flow by controlling the amount of time that the smoking article component 3 is rolled between the fingers.
- Cellulose acetate is a readily available material that is already used in components manufactured by the tobacco industry, for example, as the filtration material of cigarette filters.
- the abrasive material of the smoking article component 3 comprising cellulose acetate particles 12 simplifies manufacture of the smoking article component 3.
- the cellulose acetate particles 12 may be manufactured from a material having a melt flow in the range of 0.2 to 6 g/10 min according to ASTM D1238. In some embodiments, the cellulose acetate particles 12 may be manufactured from a material having a melt flow in the range of 0.25 to 5.5 g/10 min or in the range of 0.5 to 4 g/ 10 min. In some embodiments, the melt flow is less than 5.5 g/ 10 min.
- the cellulose acetate particles 12 comprise 28% triacetin and 72% cellulose acetate and the material has a melt flow of 414 mg/3 mins (1.38 g/ 10 min).
