This invention provides a cigarette product which releases vanillin or ethylvanillin aroma in sidestream smoke under cigarette smoking conditions. The paper wrapper of the cigarette product has a content of a flavorant-release additive which is a novel 3-vanillyl-2-hydroxypropyl or 3-ethylvanillyl-2-hydroxypropyl substituted ether derivative of cellulose.

Cigarette smoking products containing a vanillin-release additive

A purified hydroxyethylcellulose (HEC) or hydroxypropylcellulose (HPC) reacts with a perfluorinated alkyl glycidyl ether to produce an associative thickener wherein a fluorinated C.sub.8 chain is nearly as effective as a hydrocarbyl C.sub.16 straight chain hydrophobe. A preferred glycidyl ether is prepared by reacting a terminal hydroxyl of a perfluorinated surfactant with epichlorohydrin.

Perfluorinated alkyl hydrophobe hydroxyalkylcellulose associative
