The reed diffusers are made using diluted fragrance oil. The oil is mixed into a diffuser base to enable the oil to wick up the sticks.
Synthetic fragrance oils are used to fragrance the diffusers with the exception of Lemongrass, where mainly essential oil is used.
All fragrances are pre-mixed in large quantities according to specific formulas, and then bottled. This ensures consistency in the strength of all fragrances.
