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.
