What does Limonene ND do in a cosmetic formula?
This ingredient is used mainly as a fragrance component, adding fresh citrus character and helping mask base odors. It can also act as a light solvent for oily fragrance materials.
Is Limonene ND clean?
From a clean-beauty perspective, it is acceptable but has clear allergen-labeling and sensitization caveats, especially after air exposure and oxidation. It is managed through fragrance disclosure rules and IFRA-style use limits rather than treated as broadly unproblematic.
Is Limonene ND sustainable?
This material is commonly sourced from citrus peel byproducts, which gives it a renewable feedstock advantage. It is readily biodegradable, but it is volatile and supply depends on citrus agriculture and fruit-processing streams.
Is Limonene ND COSMOS-approved?
It can be permitted under COSMOS-natural and COSMOS-organic when it comes from compliant natural fragrance sources and meets purity and allergen-declaration requirements. Its renewable origin and biodegradability fit Green Chemistry well, while volatility and oxidation sensitivity are the main compromises.
How does Limonene ND work chemically?
The molecule is a small, volatile cyclic monoterpene hydrocarbon with one chiral center and reactive carbon-carbon double bonds. It is prone to autoxidation into hydroperoxides and other oxidation products, so formulas typically rely on antioxidant support, low light and air exposure, and fragrance-use levels set by the overall scent system.
