A Cigarette filter is part of an cigarette, along with cigarette paper, capsules and adhesives. The filter may be made out of cellulose acetate fibre, paper or activated charcoal (either as a cavity filter or embedded in to the cellulose acetate). Macroporous phenol-formaldehyde resins and asbestos have been found in cigarette filters The acetate and paper change the particulate smoke phase by particle retention (filtration), and finely divided carbon modifies the gaseous phase (adsorption). Filters is effective in reducing “tar” and nicotine smoke yields approximately 50%, using a greater removal rate for other classes of compounds (e.g., phenols), but you are ineffective in filtering toxins like carbon monoxide. Most factory-made cigarettes have a filter; people who roll their unique can purchase them from a tobacconist.


Cellulose acetate is done by esterifying bleached cotton or wood pulp with acetic acid. With the three cellulose hydroxy groups available for esterification, between two and three are esterified by manipulating the level of acid (degree of substitution (DS) 2.35-2.55). The ester is spun into fibers and formed into bundles called filter tow. Flavors (menthol), sweeteners, softeners (triacetin), flame retardants (sodium tungstate), breakable capsules releasing flavors on demand, and additives colouring the tobacco smoke could possibly be combined with cigarette filters. 5 largest manufactures of filter tow are Hoechst-Celanese and Eastman Chemicals in the usa, Rhodia Acetow in Germany, Daicel in Japan, and Courtaulds in the uk.

Starch glues or emulsion-based adhesives can be used for gluing cigarette seams. Hot-melt and emulsion-based adhesives can be used filter seams. Emulsion-based adhesives can be used for bonding the filters to the cigarettes.

Cellulose acetate is non-toxic, odorless, tasteless, and weakly flammable. It’s resistance against weak acids which is largely stable to mineral and fatty oils in addition to petroleum. It’s biodegradable as well as the raw materials are a renewable natural polymer likely to find application for other uses in the foreseeable future. Smoked cigarette butts contain 5-7 mg nicotine (about 25% from the total cigarette nicotine content), children ingesting >2 whole cigarettes, 6 cigarette butts or perhaps a total of 0.5 mg/kg of nicotine ought to be admitted with a hospital. Cellulose acetate is hydrophilic and retains the water-soluble smoke constituents, that lots of people are irritating (acids, alkali, aldehydes, and phenols), while letting with the lipophilic aromatic compounds.
