What it is
Chlorophyllin-Copper Complex is a semi-synthetic, water-soluble pigment made by treating natural chlorophyll so that copper occupies the center of the porphyrin ring, giving a stable green to blue-green color. In sunscreens and other cosmetics it is used at low levels to impart a green tint or to offset the off-white cast of mineral filters. It is more stable in water-based systems than native chlorophyll.
Safety & warnings
Generally well tolerated as a topical colorant at the low levels used for tinting. Because it is a green pigment it can transiently tint the skin or formula and contains copper bound within the molecule.
Origin & sourcing
Semi-synthetic; produced from plant-derived chlorophyll (commonly from alfalfa or other green plants) by saponification and exchange of the central magnesium ion for copper.
Questions everyone asks
Why is chlorophyllin-copper complex added to sunscreen?
It acts as a green colorant, used in small amounts to give a green tint or to help counteract the white cast left by mineral UV filters.
Is it the same as chlorophyll?
It is derived from chlorophyll but modified so copper replaces the central magnesium, making it water-soluble and more color-stable.
