What does fragrance (fragrance allergens: limonene do in a cosmetic formula?
This ingredient is a scenting component used to add a citrus-like note and help mask base odors in finished formulas.
Is fragrance (fragrance allergens: limonene clean?
From a clean-beauty perspective, this ingredient is acceptable but flagged because it is a recognized scent allergen with labeling thresholds in many markets. Sensitization risk rises after air and light exposure, when oxidation byproducts form.
Is fragrance (fragrance allergens: limonene sustainable?
This material can be sourced from citrus processing streams or made synthetically, so its profile depends on feedstock and supplier controls. It is readily biodegradable, but it is volatile and can contribute to formula-level VOC considerations.
Is fragrance (fragrance allergens: limonene COSMOS-approved?
It can fit COSMOS-natural or COSMOS-organic products when it comes from compliant natural aromatic materials and is properly declared as an allergen. Green Chemistry alignment is moderate, with renewable sourcing possible and good biodegradability, balanced by volatility and oxidation management needs.
How does fragrance (fragrance allergens: limonene work chemically?
This compound is a small cyclic monoterpene hydrocarbon with formula C10H16, which makes it oil-soluble, volatile, and useful at very low scenting levels. It oxidizes readily in air and light to hydroperoxides, so antioxidants, low headspace, and opaque or airtight packaging help maintain stability; allergen disclosure is commonly triggered at 0.001% in leave-on products and 0.01% in rinse-off products in the EU.
