Molecule 04 Perfume by ESCENTRIC MOLECULES, A simple, woody perfume, molecule 04 was launched by escentric molecules in 2017 as a unisex scent. The balsamic and powdery accords are made up almost exclusively from javonal, a next-level version of sandalwood. This linear sandalwood note takes up the top, middle and bottom notes, but doesn’t completely dominate the fragrance—an aura of grapefruit surrounds the perfume as it dries.
