Abstract
Smoking articles which involve the use of amphiphile-modified sorbents are disclosed. The amphiphile-modified sorbent has at least one amphiphilic compound bound to an inorganic molecular sieve substrate. The amphiphile-modified sorbent selectively removes certain constituents from cigarette smoke, while maintaining other constituents, such as those that contribute to flavor. Methods for making cigarette filters and smoking articles using amphiphile-modified sorbents, as well as methods for smoking a cigarette containing an amphiphile-modified sorbent, are also provided.
Claims16
A smoking article comprising an amphiphile-modified sorbent having at least one amphiphilic compound selected from the group consisting of an imidazoline, an ethoxylated amine, and a quaternary phospholipid bound to an inorganic molecular sieve substrate.
A cigarette filter comprising an amphiphile-modified sorbent having at least one amphiphilic compound, selected from the group consisting of an imidazoline, an ethoxylated amine, and a quaternary phospholipid bound to an inorganic molecular sieve substrate.
A method of making a cigarette filter, the method comprising incorporating an amphiphile-modified sorbent having at least one amphiphilic compound, selected from the group consisting of an imidazoline, an ethoxylated amine and a quaternary phospholipid bound to an inorganic molecular sieve substrate into a cigarette filter.
A method of making a cigarette, the method comprising:
- (i) providing a cut filler to a cigarette making machine to form a tobacco column;
- (ii) placing a paper wrapper around the tobacco column to form a tobacco rod;
- (iii) providing a cigarette filter comprising an amphiphile-modified sorbent having at least one amphiphilic compound, selected from the group consisting of an imidazoline, an ethoxylated amine and a quaternary phospholipid bound to an inorganic molecular sieve substrate;
- and
- (iv) attaching the cigarette filter to the tobacco rod to form the cigarette.
A method of smoking a cigarette comprising an amphiphile-modified sorbent having at least one amphiphilic compound, selected from the group consisting of an imidazoline, an ethoxylated amine and a quaternary phospholipid comprising lighting the cigarette to form smoke and drawing the smoke through the cigarette, wherein during the smoking of the cigarette, the amphiphile-modified sorbent removes at least one selected constituent from mainstream smoke.
