A paper strip used to evaluate perfumes outside the skin. It allows you to observe the development of the fragrance, but does not reproduce all the conditions of its wearing. The result on paper may differ from the result when applied to the skin.
Why use a paper strip
Blotter allows you to observe the fragrance without applying it directly to the skin. Clean, absorbent paper provides a convenient reference point, so strips are used when comparing multiple compositions. It is a good idea to label the strip with the name and time of application and store the samples separately. However, paper does not reproduce the temperature, humidity or lipid layer of the skin. A good test result on the strip is the beginning of getting to know the fragrance, not a guarantee of identical wearing behavior.
Separate bars help you compare the opening, middle and later background of your composition. Storing several wet samples together can mix things up. The paper itself should also be clean and odorless. When recording observations, it is better to use specific associations rather than assessing the sample only as strong or weak.
Meaning and application
The blotter helps separate the scent of the composition from contact with the skin. It is most useful for initial selection. However, it does not provide a certain answer as to how the perfume will develop while wearing, so it should not be the only basis for purchasing a larger bottle.
In practice
Sign the bar before the application: name, version and time. Use a separate strip for each composition. Store them separated so that their wet ends don't touch each other. Assess the opening and the subsequent impression in turn, rather than choosing only after the first seconds.
Do not spray one strip with several products if you want to compare them separately. Plain paper with its own odor may make grading difficult. A more intense result on the strip does not automatically indicate greater durability or a better fit for you.
