Arrowroot Extract
INCI: Maranta Arundinacea Root Extract
Arrowroot extract is a gentle, natural starch that helps absorb excess oil and soothe skin, making it a popular alternative to talc in powders and deodorants.
In plain English
Arrowroot extract comes from the root of the arrowroot plant. It's a fine, silky powder that soaks up extra oil and moisture on your skin, leaving it feeling dry and smooth without being harsh. Think of it like a natural, gentle version of baby powder or cornstarch. It also has a mild soothing effect, which is why it's often used in products for sensitive or irritated skin.

Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Arrowroot extract is a starch obtained from the rhizomes (underground stems) of the Maranta arundinacea plant. It is processed into a fine, white powder that is widely used in cosmetics as a natural absorbent and texture enhancer.
How it works
In skincare, arrowroot extract works primarily by absorbing excess sebum and moisture from the skin's surface. Its fine particles create a smooth, matte finish without clogging pores. It can also form a thin, breathable film that helps soothe minor irritation and reduce friction, making it ideal for powders, deodorants, and dry shampoos.
Pros
Gentle oil control
Arrowroot extract absorbs excess sebum without stripping the skin, making it suitable for daily use in powders and primers.
Soothing for sensitive skin
Its natural starch content can help calm minor irritation and chafing, which is why it's common in baby powders and natural deodorants.
Cons and cautions
Potential white cast
In high concentrations, arrowroot powder can leave a visible white residue on deeper skin tones, especially in loose powders or dry shampoos.
Moderate absorbency
While effective, arrowroot is less absorbent than synthetic options like silica or aluminum starch, so it may not control shine as long for very oily skin.
Best for
- People with oily or combination skin looking for a natural oil-control ingredient
- Those with sensitive skin who want a gentle, non-irritating absorbent in powders or deodorants
Use caution if
- Individuals with very dry skin may find it too absorbent, potentially leading to a tight or dry feeling
Usage tips
Safety summary
Arrowroot extract is considered very safe for topical use. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in cosmetic concentrations.
Research notes
While arrowroot has a long history of traditional use, modern cosmetic research is limited. Studies focus on its absorbent and soothing properties, but more clinical trials are needed to confirm efficacy compared to synthetic alternatives.
