What it is
Cinnamosma fragrans leaf oil is a volatile essential oil extracted from the leaves of the Cinnamosma fragrans tree, a plant in the Canellaceae family native to Madagascar. It contains aromatic compounds such as linalool and eugenol, which give it a cinnamon-like scent.
How it works
In skincare, this oil primarily functions as a fragrance ingredient. Its aromatic compounds interact with olfactory receptors, providing a pleasant scent. Some compounds may also have mild antimicrobial activity, but this is not well-studied in cosmetic formulations.
Pros
Natural fragrance source
Offers a warm, spicy scent derived from a natural plant source, appealing to those who prefer botanical ingredients.
Potential antimicrobial activity
Some compounds in the oil may help reduce microbial growth on the skin, though evidence is limited and not a substitute for preservatives.
Cons and cautions
Skin irritation risk
Essential oils like this one can cause redness, stinging, or allergic reactions, especially on sensitive or compromised skin.
Limited research
There are very few studies on Cinnamosma fragrans leaf oil specifically for cosmetic use, so its benefits and safety are not well-established.
Best for
- Those who enjoy natural, spicy fragrances in their skincare
- People with non-sensitive skin looking for aromatic products
Use caution if
- Individuals with sensitive or reactive skin
- Anyone with a known allergy to cinnamon or essential oils
Usage tips
Safety summary

Research notes
Research on this specific oil is very limited. Most knowledge comes from general studies on essential oils containing linalool and eugenol, which suggest potential antimicrobial and anti-inflammatory properties, but direct evidence for Cinnamosma fragrans is lacking.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products due to potential skin sensitization.
- Regulatory status
- Generally recognized as safe for use as a fragrance ingredient in cosmetics when used at low concentrations, but not specifically regulated by the FDA for skincare benefits.
- Common uses
- Fragranced creams, Body oils, Aromatherapy products
- Environmental note
- Cinnamosma fragrans is native to Madagascar, and sustainable harvesting practices are important to protect local ecosystems.
Good to know
- This oil is sometimes called Madagascar cinnamon, but it is not the same as true cinnamon (Cinnamomum verum).
- Essential oils can degrade with light and air, so products with this oil are best stored in opaque, airtight containers.
