Embodiment 1

[0024] 5 g of the polyglycoside compound was dissolved in 35 ml of distilled water at room temperature, and vigorously stirred to form a clear solution with a pH of 9. Take the filter tips of 20 cigarettes A (cigarettes produced in Jiangsu Province, tar: 15mg, nicotine: 1.2mg,) and dip them in this additive. After standing for 30 minutes, take them out and dry them at 40°C. and appearance unchanged. Place it in the middle of the cigarette and then collect the smoke and measure the content of nitrosamines in the smoke. In the mainstream smoke during combustion, the content of nitrosamines decreased from 3.13nmol / cigarette to 1.25nmol / cigarette, a decrease of 60.1%.

Embodiment 2

[0026] 5 g of the polyglycoside compound was dissolved in 35 ml of distilled water at room temperature, and vigorously stirred to form a clear solution with a pH of 9. Take 20 cigarettes B 1 (Cigarettes produced in Jiangsu Province, tar: 15mg, nicotine: 1.2mg,) the filter tip is immersed in this additive, after standing for 30 minutes, take it out and dry it at 40°C, the color and appearance of the filter tip will not change after drying. Place it in the middle of the cigarette and then collect the smoke and measure the content of nitrosamines in the smoke. In the mainstream smoke during combustion, the content of nitrosamines decreased from 1.67nmol / cigarette to 0.63nmol / cigarette, a decrease of 62.3%.

Embodiment 3

[0028] Dissolve 0.5 g of the polyglycoside compound in 39 ml of distilled water at room temperature, stir vigorously, add a total of 0.6 g of a mixture of polyethylene glycol and inorganic acid, stir to form a clear solution, and the pH of the solution is 2-4. Take 20 cigarettes B 1 (Cigarettes produced in Jiangsu Province, tar: 15mg, nicotine: 1.2mg,) the filter tip is immersed in this additive, after standing for 30 minutes, take it out and dry it at 40°C, the color and appearance of the filter tip will not change after drying, fluffy. Place it in the middle of the cigarette and then collect the smoke and measure the content of nitrosamines in the smoke. In the mainstream smoke during combustion, the content of nitrosamines decreased from 1.67nmol / cigarette to 0.63nmol / cigarette, a decrease of 62.3%.

Abstract

A tip filter of cigarette for decreasing the content of nitrosamine in cigarette's smoke features that it contains the tow additive in the form of liquid, which, contains polyglucoside compound, organic acid, inorganic acid, assistant and water.

Description

1. Technical field [0001] The invention relates to a cigarette filter and tow additive, in particular to a filter and tow additive for reducing the content of nitrosamines in cigarette smoke. 2. Background technology [0002] As we all know, cigarette smoke contains harmful substances nitrosamines, which exist in the mainstream smoke and sidestream smoke of cigarettes at the same time. Mainstream smoke refers to the smoke inhaled by smokers through the filter when the cigarette is burned The sidestream smoke refers to the smoke that is directly released into the air when the cigarette is naturally burned, that is, smoldering. The nitrosamines in mainstream smoke directly endanger the health of smokers; while the sidestream smoke of cigarettes diffuses around, pollutes the environment, and causes physical harm to passive smokers at the same time, so smoking is prohibited in public places. Cigarette smoke is currently the place where the human body is most exposed to nitrosam...
