Ingredient review
Amyl Cinnamal
INCI: AMYL CINNAMAL
A common synthetic fragrance allergen that can cause skin reactions in sensitive individuals, but is generally safe for most people at low concentrations.
In plain English
Amyl Cinnamal is a man-made chemical that smells like jasmine or hyacinth. It's added to many scented products like perfumes, lotions, and shampoos to give them a floral aroma. However, it's also a known allergen, meaning some people can develop redness, itching, or a rash when their skin comes into contact with it. Because of this, it's required to be listed on ingredient labels in many countries so people with sensitivities can avoid it.

What it is
Amyl Cinnamal is a synthetic aromatic aldehyde that is widely used as a fragrance ingredient. It is not derived from natural jasmine but is chemically created to mimic its scent. It is one of the 26 fragrance allergens that must be individually labeled on cosmetic products in the European Union.
How it works
In a cosmetic product, Amyl Cinnamal serves solely as a fragrance component. It does not provide any skincare benefit like moisturizing or anti-aging. It works by evaporating from the skin or hair, releasing its floral scent. When it comes into contact with skin, it can sometimes trigger an allergic reaction in people who are sensitized to it, causing inflammation and irritation.
Pros
Pleasant floral scent
Provides a natural-smelling jasmine-like fragrance that enhances the sensory experience of using a product.
Regulatory transparency
Because it's a known allergen, it must be listed on labels, allowing consumers with sensitivities to easily identify and avoid it.
Cons and cautions
Allergen risk
Amyl Cinnamal is one of the most common fragrance allergens and can cause contact dermatitis, including redness, itching, and swelling, especially with repeated use.
No skincare benefit
This ingredient adds only scent and does not contribute to the health, hydration, or appearance of your skin or hair.
Best for
- People without fragrance allergies who enjoy floral scents
- Those using products where the ingredient is at very low levels and not left on skin
Use caution if
- Individuals with known fragrance allergies or sensitive skin
