| 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. |
