7. Limonene Fragrance Flavouring Industrial solvent 1.5% 90%
Limonene is a colourless liquid hydrocarbon classified as a cyclic terpene. The more common D isomer possesses a strong smell of oranges. It is used in chemical synthesis as a precursor to carvone and as a renewably based solvent in cleaning products.
D-Limonene is obtained commercially from citrus fruits through two primary methods: centrifugal separation or steam distillation.
In contrast, L-limonene has a piney, turpentine-like odor.

10. Water cleaning
Research in Morocco shows that orange peel (without modification, can be used successfully to clean up acid dyes that are discharged into rivers. Research also shows it can adsorb heavy metals such a lead and cadmium.
In addition, it can also be used to make activated charcoal which is even more effective
