Cinnamal ●
TL;DR. This ingredient is primarily a fragrance material, used to add a warm, spicy odor profile and to support masking in scented formulas.
What does Cinnamal do in a cosmetic formula?
This ingredient is primarily a fragrance material, used to add a warm, spicy odor profile and to support masking in scented formulas.
Is Cinnamal clean?
From a clean beauty perspective, this ingredient has more friction than many simple aroma materials because it is a recognized fragrance allergen and skin sensitizer for some people. It is typically managed through IFRA limits and allergen labeling rules rather than treated as broadly unproblematic.
Is Cinnamal sustainable?
This material can be plant-derived through natural aromatic sources or made synthetically, so its sustainability profile depends on the supply route. It is expected to biodegrade more readily than persistent silicone or fluorinated materials, but fragrance supply chains still need traceability and responsible sourcing.
Is Cinnamal COSMOS-approved?
It can align with COSMOS only when supplied as a compliant natural fragrance component within an allowed fragrance blend, while petrochemical or nature-identical synthetic grades do not fit COSMOS-natural or COSMOS-organic fragrance rules. Its Green Chemistry profile is mixed, with small use levels and reasonable biodegradability balanced against sensitization and sourcing caveats.
How does Cinnamal work chemically?
This molecule is an aromatic alpha,beta-unsaturated aldehyde, which explains its strong odor impact and its reactivity with amines and other nucleophiles. It is used at trace fragrance levels, with EU allergen declaration thresholds of 0.001% in leave-on products and 0.01% in rinse-off products, and formula stability is better when oxidation and high-pH exposure are controlled.
