Our reed diffusers are made with Augeo, a plant-based solvent that releases scent slowly and evenly. It is around 70% renewable and has a carbon footprint up to 40% lower than dipropylene glycol (DPG), the conventional industry standard used in most reed diffusers. It is also biodegradable, low-odour, and non-toxic, which means the fragrance comes through cleanly without a chemical base note underneath it.
