cellulose acetate definition

Cellulose acetate is derived from cellulose which is used in the processing of lacquers, plastics, photographic film and textile fibers.  Because it is less flammable that celluose nitrate, it is less dangerous to use in film.  Moreover, it does not yellow to the same degree as cellulose nitrate does in the daylight; however, cellulose acetate does not last as long, is not as hard and lacks other lacquer properties.  Permanent constructions or paintings should not use cellulosic products due to their instability.
