Ingredient review
Thaumatococcus Daniellii Fruit Extract
INCI: THAUMATOCOCCUS DANIELLII FRUIT EXTRACT
A natural sweetener and mild antioxidant from a West African fruit, used mainly for flavor in lip products rather than for skin benefits.
In plain English
This ingredient comes from the fruit of the katamfe plant, which grows in West Africa. The fruit is famous for being incredibly sweet—much sweeter than sugar—so it's used in tiny amounts to add a pleasant taste to lip balms or glosses. It also contains some antioxidant compounds that might help protect skin from environmental damage, but its main job in cosmetics is flavoring, not active skincare.

What it is
Thaumatococcus Daniellii Fruit Extract is a natural extract derived from the fruit of the katamfe plant. The fruit contains thaumatin, a protein that is about 2,000 times sweeter than sugar. In cosmetics, it is used primarily as a flavoring agent in lip products and occasionally as a mild antioxidant.
How it works
In a cosmetic product, this extract works mainly by providing a sweet taste without adding sugar or artificial sweeteners. The thaumatin protein binds to taste receptors on the tongue, creating a perception of sweetness. As an antioxidant, it may help neutralize free radicals on the skin's surface, though this effect is minimal at the low concentrations typically used.
Pros
Natural sweetener
Provides intense sweetness from a plant source, allowing very low usage levels in lip balms and glosses without adding sugar or artificial chemicals.
Generally safe
Has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin, when used in typical concentrations.
Cons and cautions
Limited skincare benefit
Its primary role is flavoring, not active skincare. The antioxidant effect is minimal at the low concentrations used, so it won't significantly improve skin health.
Emerging evidence
There is very little published research on its effects when applied to the skin, so its long-term benefits and safety are not well-established compared to more studied ingredients.
Best for
- Anyone looking for a natural sweetener in lip products
- People who prefer plant-based ingredients over artificial flavors
Use caution if
- Individuals with known allergies to Thaumatococcus or related plants
Usage tips
Safety summary
Thaumatococcus Daniellii Fruit Extract is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. However, as with any plant extract, there is a small risk of allergic reaction in sensitive individuals. The evidence for topical safety is limited but no significant concerns have been reported.
Research notes
Research on this extract is primarily focused on its sweetening properties in food science. There are very few peer-reviewed studies on its cosmetic or dermatological effects. The antioxidant activity has been noted in preliminary lab studies, but clinical evidence on skin benefits is lacking.
Common label clues
- Typical concentration
- Typically used at very low concentrations (0.01% to 0.5%) due to its potent sweetness.
- Regulatory status
- Approved for use in cosmetics in the EU and US as a flavoring agent. Not specifically regulated as an active skincare ingredient.
- Common uses
- Lip products, Flavored balms, Fragrance formulations
- Environmental note
- The katamfe plant is native to West Africa and is cultivated sustainably in some regions, though large-scale harvesting practices are not well-documented.
Good to know
- Thaumatin, the sweet protein in this extract, is also used as a food additive (E957) in some countries.
- The katamfe fruit is traditionally used in West African cuisine to sweeten foods and drinks.
