Ingredient review
Cinnamon Wood Oil
INCI: Cinnamomum Culilawan Wood Oil
Cinnamon Wood Oil adds a warm, spicy scent and may offer antimicrobial benefits, but it is a known skin irritant and allergen, so it's best used in low concentrations and avoided by sensitive skin.
In plain English
Cinnamon Wood Oil is an essential oil pressed from the wood of a cinnamon tree. It smells warm and spicy, and it can help fight some bacteria on the skin. However, it's also a common cause of skin irritation and allergic reactions, especially if used in high amounts or on sensitive skin.

What it is
Cinnamon Wood Oil is a natural essential oil extracted from the wood of the Cinnamomum culilawan tree, a species related to the more common cinnamon. It contains aromatic compounds like cinnamaldehyde, which give it its characteristic scent and some antimicrobial activity.
How it works
In a cosmetic product, Cinnamon Wood Oil primarily acts as a fragrance ingredient, providing a warm, spicy aroma. It also has some antimicrobial properties, meaning it can help reduce the growth of certain bacteria and fungi on the skin's surface. However, these effects are mild and the oil's main role is scent.
Pros
Natural fragrance
Provides a warm, spicy scent that many find appealing, without synthetic fragrance chemicals.
Mild antimicrobial properties
May help reduce surface bacteria in products, though this is not a primary benefit for skin health.
Cons and cautions
High irritation risk
Cinnamon Wood Oil is a known skin irritant and can cause redness, stinging, or burning, especially in leave-on products or at higher concentrations.
Common allergen
It is a frequent cause of allergic contact dermatitis, meaning repeated use can lead to an allergic reaction even if you've used it before without issues.
Best for
- People who enjoy warm, spicy fragrances in their skincare and do not have sensitive or reactive skin
- Those looking for a natural fragrance alternative in products like soaps or body washes
Use caution if
- Anyone with sensitive, eczema-prone, or easily irritated skin
- Individuals with a known allergy to cinnamon or balsam of Peru
Usage tips
Safety summary
Cinnamon Wood Oil is safe for use in cosmetics at low concentrations, but it carries a high risk of skin irritation and allergic reactions. It is best suited for wash-off products like soaps and should be avoided by those with sensitive skin or cinnamon allergies.
Research notes
Research confirms that cinnamaldehyde, the main component of cinnamon oil, has antimicrobial and anti-inflammatory properties in lab studies. However, clinical evidence for skin benefits is limited, and the oil's irritant potential is well-documented in dermatological literature.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products due to potential skin irritation
- Regulatory status
- Cinnamon Wood Oil is approved for use in cosmetics in the US and EU, but its concentration is restricted by IFRA guidelines to minimize skin irritation. It must be listed on the ingredient label.
- Common uses
- Fragranced products, Soaps, Body lotions
- Environmental note
- Cinnamon trees are generally cultivated, but overharvesting for essential oil can impact local ecosystems. Look for sustainably sourced oils if environmental impact is a concern.
Good to know
- Cinnamon Wood Oil is different from cinnamon bark extract, which is water-soluble and less irritating.
- The International Fragrance Association (IFRA) restricts the use of cinnamon oil in leave-on products to low concentrations due to irritation concerns.
