Ingredient review
Tanacetum Cinerariifolium Root Extract
INCI: TANACETUM CINERARIIFOLIUM ROOT EXTRACT
A botanical root extract with insect-repelling history, but its use in skincare is limited and may cause irritation for sensitive skin.
In plain English
This is an extract from the root of a flower often called pyrethrum or Dalmatian chrysanthemum. It's best known for its natural insect-repelling abilities, not for improving skin. In skincare, it's used in tiny amounts because it can be irritating and has a strong smell. There's very little research showing it helps skin look or feel better.

What it is
A natural extract derived from the roots of Tanacetum cinerariifolium, a plant in the daisy family. The plant is historically used to produce pyrethrins, natural insecticides.
How it works
In cosmetic products, it may act as a fragrance component or a very mild astringent. However, its primary mechanism is insecticidal, not skin-beneficial. Any skin effects are likely due to other compounds in the extract, not the pyrethrins themselves.
Pros
Natural insect repellent
The plant is a well-known source of natural pyrethrins, which can repel insects in leave-on products like lotions or sprays.
Botanical origin
Derived from a plant source, appealing to those who prefer naturally sourced ingredients over synthetic alternatives.
Cons and cautions
Irritation risk
Can cause skin irritation, redness, or allergic reactions, especially in people with sensitive skin or allergies to related plants.
Limited skin benefits
There is little to no scientific evidence that this extract improves skin hydration, texture, or appearance. Its main use is insecticidal, not cosmetic.
Best for
- Those seeking natural insect repellent in a cosmetic product
- Individuals without sensitive skin or known allergies to daisy-family plants
Use caution if
- People with sensitive skin, eczema, or allergies to ragweed, marigolds, or other daisy-family plants
Usage tips
Safety summary
Generally considered safe at low concentrations in cosmetics, but can cause skin irritation and allergic reactions, particularly in sensitive individuals or those allergic to daisy-family plants.
Research notes
Research on this extract for cosmetic purposes is very limited. Most studies focus on the insecticidal properties of the plant's flowers, not the root extract for skin health.
Common label clues
- Typical concentration
- Typically used at very low concentrations (under 1%) due to potential irritation and strong odor.
- Regulatory status
- Approved for use in cosmetics in the EU and US, but concentrations are typically low due to irritation potential. Not classified as a drug ingredient.
- Common uses
- Insect repellent products, Limited skincare formulations
- Environmental note
- The plant is cultivated for insecticide production, which can have environmental impacts from farming practices. Sourcing may vary.
Good to know
- This extract is not the same as pyrethrin, the purified insecticidal compound. The extract contains many plant compounds.
- Products with this extract may have a strong, herbal scent that some find unpleasant.
- It is rarely used in mainstream skincare; you are more likely to find it in natural insect repellents.
