About

Buckwheat flour — a gentle exfoliating and absorbing plant flour rich in rutin, used mostly in powder masks and cleansers. Clean, food-grade profile.

Polygonum fagopyrum (buckwheat) flour is milled from food-grade buckwheat grains and contains starch, proteins, and the flavonoid rutin. In cosmetics it functions as a mild physical exfoliant and bulking/absorbing agent, typically in powder masks and cleansing grains. Listed in EU CosIng without restriction. It is gluten-free, making it useful for formulators avoiding wheat, though buckwheat allergy (distinct from gluten) is reported in a minority of users. The flavonoid content contributes mild antioxidant properties. No CIR monograph, no IARC concern.
