CINNAMAL
Commonly Found In
Overview
Cinnamal (cinnamaldehyde) is the principal aromatic aldehyde responsible for the characteristic scent and flavor of cinnamon, found mainly in cassia and Ceylon cinnamon bark oils. It is used as a fragrance ingredient in cosmetics and is a mandatory EU labeling allergen above 0.001% in leave-on products (Annex III/76). Studies identify cinnamal as one of the most potent contact sensitizers among the 26 EU-regulated fragrance allergens, with sensitization rates of approximately 2β4% in patch-tested dermatitis patients. It is permitted in the US and Japan for cosmetic use without specific labeling requirements.
Also known as: Cinnamal, Cinnamaldehyde, Cinnamic Aldehyde, 3-Phenyl-2-propenal, trans-Cinnamaldehyde
Key Benefits
Studies suggest cinnamal may contribute antimicrobial properties; its cosmetic value is primarily as a fragrance and flavoring ingredient, not as a skin treatment.

π Why Regulations Differ
The EU requires mandatory label disclosure of cinnamal (Annex III/76) as part of the 26 fragrance allergen labeling regime; it is not prohibited. The 'banned' database status reflects the Annex III restricted classification. The US and Japan do not require specific labeling. IFRA provides voluntary concentration limits internationally.

Strictness Ranking
πΏ Natural Sources
Found abundantly in cassia cinnamon bark oil (75-90%), Ceylon cinnamon bark oil (40-65%), and cinnamon leaf oil (1-5%). Also present in hyacinth, narcissus, patchouli, and storax. Cassia cinnamon is the primary natural source for commercial extraction.
π How It's Made
Extracted from cinnamon bark oil through fractional distillation. Synthetically produced via aldol condensation of benzaldehyde and acetaldehyde in the presence of a base catalyst. Most commercial cinnamal is synthetic due to cost-effectiveness and consistency, though natural sources are used in premium products.
π Uses in Cosmetics
Used as fragrance component in oriental, spicy, and cinnamon-scented products at 0.01-1% concentration. Provides characteristic warm, sweet, spicy cinnamon aroma. Functions as denaturant and flavoring agent. EU Regulation (EC) No 1223/2009 Annex III/76 requires mandatory labeling above 0.001% (leave-on) or 0.01% (rinse-off). One of the more potent sensitizers among fragrance allergens.
π¬ Other Applications
Widely used as a food flavoring in candies, beverages, and baked goods. Also found in some insect repellents and pharmaceuticals. Has natural antimicrobial properties.

Frequently Asked Questions
Why is CINNAMAL banned in the EU but allowed in the US?
The EU follows a precautionary principle, banning CINNAMAL under III/76 due to potential safety concerns. The US FDA has not found sufficient evidence to prohibit its use, allowing it under different safety assessment standards. This reflects differing regulatory philosophies between the two regions.
Why is CINNAMAL banned in the EU but allowed in Japan?
The EU prohibits CINNAMAL (III/76) based on their strict safety criteria. Japan's Ministry of Health, Labour and Welfare (MHLW) has evaluated the ingredient and permits its use, potentially with different safety data or usage conditions.
What is CINNAMAL used for in cosmetics?
CINNAMAL is primarily used for denaturant in cosmetic products. It also serves as flavouring, perfuming. The ingredient is commonly found in various cosmetic and personal care products.
Which countries regulate CINNAMAL?
CINNAMAL is banned in EU. It has concentration limits or usage restrictions in UK. The ingredient is freely allowed in JP, US.
Are there alternatives to CINNAMAL?
Due to regulatory restrictions on CINNAMAL, cosmetic manufacturers often use alternative ingredients with similar functions.
