The note of plastic is an intriguing and multifaceted phantom, a smell of non-nature. It rarely exists as a singular, direct extraction, but rather as an accord crafted to evoke a range of synthetic textures. It can manifest as the pristine, waxy-smooth scent of a brand-new doll head, replete with a slightly sweet, almost vanillic warmth and a subtle rubbery undertone. At other times, it's the sharper, more expansive aroma of PVC or vinyl, carrying an effervescent, slightly metallic sheen and a clean, almost industrial sterility. The projection can vary wildly; a 'new toy' plastic might be intimate and comforting, while an 'industrial plastic' could be quite broad and assertive, almost acrid. Its longevity is usually moderate, typically residing in the top to heart transition, providing a distinct modern texture rather than a deep, grounding base. It lacks the typical organic evolution of natural notes, maintaining a relatively linear, synthetic character, yet offering surprising nuance depending on the specific plastic material it seeks to emulate.
