Ingredient review
Arrowroot Powder
INCI: Maranta Arundinacea Root Powder
A gentle, plant-based powder that soaks up shine and adds a smooth feel without clogging pores.
In plain English
Arrowroot powder is a fine, silky starch made from the root of a tropical plant. In skincare and cosmetics, it works like a sponge to absorb extra oil and moisture on your skin, leaving a soft, matte finish. It's a popular natural alternative to talc or cornstarch because it's very unlikely to irritate or clog pores.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A natural starch powder obtained by washing, drying, and grinding the rhizomes (roots) of the Maranta arundinacea plant, native to South America.
How it works
Arrowroot powder's fine particles have a high surface area that physically absorbs excess sebum and sweat. When applied to the skin, it creates a thin, breathable layer that reduces shine and friction, helping makeup stay in place or keeping skin dry in deodorants and body powders.
Pros
Gentle on sensitive skin
Arrowroot powder is non-irritating and non-comedogenic, making it a safe choice for those prone to breakouts or irritation from synthetic powders.
Eco-friendly and natural
Derived from a renewable plant source, it's biodegradable and often preferred by consumers avoiding talc or synthetic microplastics.
Cons and cautions
Moderate oil control
While it absorbs oil well initially, it may not keep skin matte as long as silica or clay, requiring more frequent touch-ups for very oily skin.
Texture can vary
If not ultra-finely milled, arrowroot powder can feel slightly chalky or gritty, which may affect the smoothness of high-end face powders.
Best for
- People with oily or combination skin looking for a natural shine-control powder
- Anyone seeking a talc-free, gentle powder for dry shampoo or deodorant
Use caution if
- Individuals with very dry skin may find it too absorbent, leading to a powdery or tight feel
Usage tips
Safety summary
Arrowroot powder is considered very safe for topical use. It has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive and acne-prone skin. No significant safety concerns have been reported in cosmetic applications.
Research notes
While specific cosmetic studies on arrowroot powder are limited, its use as an absorbent and texturizer is well-established in traditional and natural cosmetics. Its safety profile is supported by its long history of use in food and personal care products.
Common label clues
- Typical concentration
- 1-20% depending on product type (higher in powders, lower in pressed formulas)

- Powders, Dry shampoos, Deodorants, Loose face powders
- Environmental note
- Arrowroot is a sustainable crop that grows quickly with minimal pesticides, and the powder is fully biodegradable.
Good to know
