Cinnamon Bark
Cinnamomum verum (syn. C. zeylanicum)
Sweet, hot and rich: the cinnamon of cinnamon rolls and red-hot candies. Very potent and slightly biting.
- Skin sensitizer — keep low in anything touching skin
- Can irritate skin or mucous membranes
- Caution around pets (especially cats and birds) — don't diffuse in their space
- Accelerates trace or seizes in cold-process soap
- Discolors soap or wax (usually tan to dark brown)
- IFRA-restricted material — use the supplier's certificate limits
How it behaves
Excellent hot throw. It's costly, so most makers use it as an accent over cinnamon leaf or a cinnamon fragrance oil.
A drop or two in a blend at most, because it irritates eyes and airways.
Avoid. Cinnamaldehyde is a strong skin sensitizer, and it also accelerates trace and browns soap. Use cinnamon leaf or a skin-safe cinnamon fragrance oil instead.
Avoid for the same skin-sensitizing reason as cold process.
Not worth it: it's expensive and sensitizing on fabric that touches skin.
Pairs well with
Don't have it? Try Cinnamon Leaf.
