A term for a material that helps shape the development and persistence of a fragrance composition. It does not mean one universal substance. The presence of materials with low volatility does not allow us to promise the same number of hours of durability on each skin.
The role of materials in the background of the composition
The term fixative includes materials and formulations that help shape odor persistence. Some of these ingredients have a distinct profile themselves, others are perceived more subtly. They do not act as a stationary cover enclosing all the notes on the skin. The development of a composition still depends on its overall composition, application and environment. A long noticeable background may remain after the fresh opening has disappeared; The durability of one accent does not mean that the entire perfume remains unchanged.
In the descriptions, it is worth separating the lingering scent close to the skin from its perceptibility in the room. A strong, long-lasting background does not have to give a lot of projection. The word fixer does not establish a guaranteed number of hours, because the finished composition and application conditions remain important.
Meaning and application
The durability of ready-made perfumes results from the formulation and method of use, not from one magical name. The term fixative describes the function of the material in the composition. It does not provide the user with a universal conversion factor or a guarantee that the scent will last for a specific number of hours.
In practice
Compare products in similar conditions and pay attention to later stages of composition. Record the number of applications, place and time. This will make it easier to separate durability from strong opening and from your own habit to the scent.
Do not add fixatives to the finished bottle yourself. You can change the formulation, solubility and application method. Read the manufacturer's declaration as a description of a specific formula, not an instruction on how to create your own cosmetic from random raw materials.
