Arrowroot Starch

What is it?	Arrowroot starch (or arrowroot powder) is a fine, starchy powder.
INCI	Maranta Arundinacea Root
Appearance	Fine white powder
Usage rate	Up to 100%
Texture	Soft and silky
Scent	Nothing noticeable
Solubility	Insoluble
Why do we use it in formulations?	In anhydrous products it helps reduce the greasy/oily skin feel, and in higher concentrations it can give the entire product a powdery, dry-touch finish and contribute to thickening. In powdered cosmetics it acts as a diluent and improves slip. It can also be used in dusting powders, or even used as-is for a dusting powder.
Do you need it?	No.
Strengths	Ultra silky, inexpensive ingredient.
Weaknesses	I can’t think of any, though it is easily replaced.
Alternatives & Substitutions	Other starches like corn and wheat work well in its place.
How to Work with It	Include it in the heated or cool down phase, or the grinding phase of powdered products.
Storage & Shelf Life	Stored somewhere cool, dark, and dry, arrowroot starch should last up to three years.
Tips, Tricks, and Quirks	Despite all my best efforts I’ve never been able to bake arrowroot biscuits that taste like the delicious arrowroot biscuits we give to kids. If you have a brilliant recipe, please get in touch!
