A fixative is a substance that is used to preserve or stabilize something, such as a drawing or a scent. It can be sprayed onto the item to protect it from smudging, fading, or deteriorating over time. For example, an artist may use a fixative on a pencil drawing to prevent the graphite from rubbing off, while a chemist may use a fixative to preserve the scent of a perfume. The word fixative can also be used to describe a substance that sets or hardens a material, such as a glue or sealant.
