Harm score: 1 (Natural substances)
Cellulose acetate, also known as acetylcellulose or cellulose acetate, is a biopolymer that has earned an important position in various industries due to its properties and wide range of applications. It is a transparent and glossy material that is created by the acetylation of cellulose, in other words by processing cellulose with acetic acid. This process leading to the production of cellulose acetate was first patented in 1865.
The products in which cellulose acetate is used are incredibly diverse. For example, it can be found in food packaging, where its ability to prevent oxygen from entering the food increases its shelf life. In the textile industry it is often used as a base material for the production of rayon, known by the trade name 'acetate'. Other uses are in optics, where it is used to make spectacle frames, and in cinematography, where it is used to make film stock. Its durability, elasticity and mouldability also make cellulose acetate suitable for use in cosmetic packaging, cable packaging and tool parts. It is also used in cigarette filters, where it provides the necessary strength and absorption properties.
