About

Dwarf rush stem powder — a fibrous East Asian botanical used in traditional and modern formulations. Thin modern safety data.

Juncus decipiens stem powder is milled dried stem of a rush species native to East Asia (used traditionally in Japan and Korea for mat weaving and herbal applications). It consists mainly of cellulose, lignin, and trace flavonoids. Functions in cosmetics include mild absorbent, texturizer, and skin-conditioning powder. EU CosIng lists it in general botanical ingredient categories. No Annex II/III restriction. No formal CIR or SCCS review. Cosmetic-specific safety data is very limited, so scored conservatively.
