Molecule 01 + Mandarin consists of Iso E Super + Mandarin.
Iso E Super is an abstract synthetic molecule characterised as a cedarwood note with a warm, velvety cocooning sensation. 
Mandarin is a natural extracted from the mandarin orange.
Geza Schoen: "Mandarin is all about the instant hit. It's so alive, the way it radiates off the skin with that citrus zestiness. But there’s more to mandarin; it’s very fruity and aromatic as well. It's a beautiful ingredient. Its transparency means that it vanishes quickly. I've touched it up with a little extra shading to extend it, adding a mandarin ingredient used in flavourings to give it super-juiciness. Then as it begins to fade, Molecule 01 syncs in, bringing a warm, erogenous feeling to play with that zinging freshness. That's unusual – for a topnote ingredient like Mandarin and a base note like Iso E Super to dance together naked like this, without other notes coming between them. And then the mandarin is almost gone, and you are left with the elevated simplicity of Molecule 01. 
That’s what I love about Molecule 01 + Mandarin – it may be a dance of two but the story changes completely from beginning to middle to end."
