What it is
This ingredient is the water-based portion derived from the tankan orange (Citrus tankan), a hybrid citrus cultivated mainly in the Kyushu and Okinawa regions of Japan. It is typically incorporated as part of the water phase to add a botanical character and light conditioning effect to a formula. As a fruit-derived water it carries trace plant constituents rather than acting as a concentrated functional active.
Safety & warnings
As a citrus-derived ingredient it may contain trace amounts of naturally occurring fragrant compounds such as limonene, which is a recognized fragrance allergen, so sensitive or fragrance-reactive users may wish to patch test.
Origin & sourcing
Natural; the aqueous fraction collected from tankan orange fruit, a citrus grown in southern Japan.
