The note of papier-mâché is a marvel of olfactory abstraction, presenting as a dry, subtly fibrous, and starchy essence. It evokes the crisp, almost brittle texture of dried paper pulp, often with a faint, clean dustiness clinging to its edges. There's an underlying dryness, akin to aged paper or the inside of an empty cardboard box, yet it's not entirely devoid of warmth. One might detect a whisper of something faintly sweet, like a very diluted, unsweetened starch paste, or even a ghost of a metallic, almost ozonic tang that speaks to the drying process. Its intensity is typically low to moderate, projecting softly, often perceived as a 'skin scent' that invites closeness. As an accord, it functions primarily as a unique heart or base note, offering an unexpected textural element rather than a dominant aromatic presence. Its longevity is usually moderate, as its subtle nature tends to blend seamlessly into the background, providing a foundational dryness or a canvas for other notes.
