About

Japanese indigo (Persicaria tinctoria) leaf powder for vibrant natural color.

Persicaria tinctoria (Japanese indigo) leaf powder has been used traditionally for its indigo content which provides blue-violet pigmentation. It is not listed in EU Annexes II–VI and is considered safe at cosmetic-use levels. However, as with many plant powders, potential sensitisation cannot be entirely excluded for atopic individuals. No specific concentration limits are established under EU Cosmetics Regulation.
