Coloring ingredients

Browse Japanese ingredients by the functional benefit they deliver — brightening, antioxidant, gut health, sleep quality, etc. This page lists 8 ingredients tagged with the Coloring ingredient function, helping formulators and brand planners shortlist candidates by use case rather than by category alone. Examples include Beni Imo (Okinawan Purple Sweet Potato), Black Rice Extract, Japanese Bamboo Charcoal, and Lithospermum Erythrorhizon Root Extract.

Function claims permitted on a finished product depend on the target market and regulatory pathway (cosmetic, quasi-drug, FFC, Tokuho, dietary supplement). The function tag here is an editorial summary of the ingredient's documented or traditional benefit, not an approved claim. Always verify claim wording against your target-market rules.
