Haihtumiskeston

Haihtumiskeston, often translated as evaporation time or persistence, refers to the duration for which a scent remains noticeable. This is a crucial factor in the perception and evaluation of perfumes, colognes, and other scented products. The longevity of a fragrance is influenced by a complex interplay of factors including the concentration of aromatic compounds, the type of ingredients used, and the skin chemistry of the wearer.

Fragrance notes are typically categorized into top, middle, and base notes, each with varying volatilities. Top notes are the most volatile and evaporate quickly, forming the initial impression of a scent. Middle notes, also known as heart notes, emerge as the top notes fade and typically last longer. Base notes are the least volatile and provide the foundation of the fragrance, lingering for the longest period. Therefore, a scent with a strong base note profile generally exhibits a longer haihtumiskeston.

Environmental conditions also play a role. Higher temperatures can accelerate evaporation, reducing the perceived duration of a fragrance. Similarly, humidity levels can affect how scent molecules interact with the air. Skin chemistry is another significant variable; the natural oils and pH of an individual's skin can alter the way a fragrance develops and persists. Some individuals find fragrances last longer on their skin than others, due to these personal biological differences. Understanding haihtumiskeston is key for both perfumers in their creations and consumers in their selection of scented products.
