An air freshener has a plurality of ethylene-vinyl-acetate beads.
Ethylene-vinyl acetate is the copolymer of ethylene and vinyl acetate.
ethylene-based glycol ethers and terpenes are also used in air freshener. these sublime and get converted to vapours directly so they disappear after a few weeks without a trace.

They sublime - turn directly from a solid to a vapor.
