Ingredient review
Linalyl Cinnamate
INCI: Linalyl Cinnamate
Linalyl Cinnamate is a synthetic fragrance ingredient that adds a sweet, floral scent to products but may cause skin irritation in sensitive individuals.
In plain English
Linalyl Cinnamate is a man-made chemical that smells like a mix of floral and sweet notes, often used to give cosmetics a pleasant scent. It's not a moisturizer or active treatment—it's purely there for fragrance. Because it's a potential skin sensitizer, people with sensitive or allergy-prone skin may want to avoid products containing it.

What it is
Linalyl Cinnamate is a synthetic ester formed from linalool and cinnamic acid. It is not naturally derived in commercial quantities; it's created in a lab for consistent fragrance quality.
How it works
In a cosmetic product, Linalyl Cinnamate acts as a fragrance ingredient by evaporating from the skin and releasing its scent. It does not provide any skincare benefit like hydration or anti-aging; its sole purpose is to impart a pleasant aroma.
Pros
Pleasant scent
Provides a sweet, floral aroma that many find appealing in lotions, perfumes, and body washes.
Consistent quality
Being synthetic, it offers a uniform scent profile batch to batch, unlike natural extracts that can vary.
Cons and cautions
Potential irritant
Classified as a potential skin sensitizer; repeated use may lead to redness, itching, or allergic reactions in some people.
No skincare benefit
Adds fragrance only—does not hydrate, soothe, or improve skin health, so it's an unnecessary extra for those seeking functional products.
Best for
- People who enjoy scented cosmetics and have no known fragrance allergies
- Those looking for a sweet, floral scent in their products
Use caution if
- Individuals with sensitive skin or a history of fragrance allergies
- Anyone with eczema or contact dermatitis who may react to fragrance ingredients
Usage tips
Safety summary
Linalyl Cinnamate is considered safe for most people at the low concentrations used in cosmetics, but it is a known skin sensitizer. Individuals with fragrance allergies or sensitive skin should approach with caution and consider fragrance-free options.
Research notes
Research indicates that Linalyl Cinnamate can cause allergic contact dermatitis in susceptible individuals. It is included in fragrance allergen lists by regulatory bodies like the EU Scientific Committee on Consumer Safety. No evidence supports any therapeutic skincare benefits beyond fragrance.
Common label clues
- Typical concentration
- Typically used at very low concentrations, often below 1%
- Regulatory status
- In the EU, Linalyl Cinnamate is listed as a potential allergen and must be declared on the label if its concentration exceeds 0.001% in leave-on products or 0.01% in rinse-off products. In the US, it is generally recognized as safe for use in cosmetics at low concentrations, but no specific labeling requirement exists.
- Common uses
- Perfumes, Fragranced lotions, Body washes, Hair products
- Environmental note
- As a synthetic compound, its environmental impact depends on production methods and disposal; it is not biodegradable in all conditions, so it may persist in water systems.
Good to know
- Linalyl Cinnamate is often listed under 'fragrance' or 'parfum' on ingredient labels, so it may not appear by name.
- It is regulated as a fragrance allergen in the EU and must be listed separately if present above certain levels.
