In 1920, George Eastman established the site that would later become the headquarters for Eastman Chemical to provide a reliable domestic supply of compounds for Kodak's photographic processes. With the company's knowledge of acetyl chemistry for film production, Tennessee Eastman developed compounded cellulose acetate in 1929, which was sold ...
Kodak began working with acetate "safety film" as early as 1909, and started selling it in 1910 for 22 mm film. Acetate has always been used with 8 mm and 16 mm formats, as they were originally created for amateur home movie usage, and generally was used for most sub-35 mm formats to minimize risk to the general public.
