Chlorophyllin-Copper Complex
INCI: CI 75810
A safe, plant-derived green colorant that adds a natural-looking tint to products without known skin irritation.
In plain English
CI 75810 is a green pigment made from chlorophyll, the stuff that makes plants green. It's processed to be stable in skincare and makeup, so it doesn't fade or change color. You'll see it in green-tinted products like color-correcting primers or natural-looking soaps. It's considered very gentle on skin and is widely used in cosmetics around the world.

Quick decision guide
Useful, but context matters
Chlorophyllin-Copper Complex is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Chlorophyllin-Copper Complex.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic colorant derived from chlorophyll (the green pigment in plants) by replacing the central magnesium atom with copper to improve stability and colorfastness.
How it works
It sits on the surface of the skin or hair, reflecting green light to impart a green tint. In color-correcting makeup, it neutralizes redness. It does not penetrate the skin or provide any active skincare benefit beyond coloring.
Pros
Gentle on skin
CI 75810 has a very low irritation and allergy risk, making it suitable for sensitive skin and even around the eyes.
Plant-derived appeal
Because it starts from natural chlorophyll, it appeals to consumers looking for naturally sourced colorants, though it is chemically modified for stability.
Cons and cautions
No skincare benefit
Unlike some plant extracts, CI 75810 does not moisturize, soothe, or protect skin—it only adds color.
Potential staining
In high concentrations or on porous surfaces, it can leave a green stain on fabrics or towels.
Best for
- Anyone looking for a gentle green colorant in their cosmetics
- People with sensitive skin who want to avoid synthetic coal-tar dyes
Use caution if
- Those seeking a skincare active ingredient—this is purely a colorant
Usage tips
Safety summary
CI 75810 is considered safe for use in cosmetics at typical concentrations. It has a low potential for skin irritation and sensitization. The copper content is tightly bound and not bioavailable, so toxicity is not a concern in cosmetic use.
Research notes
Studies confirm low acute toxicity and no significant skin irritation or sensitization. The Cosmetic Ingredient Review (CIR) panel has reviewed related chlorophyllin derivatives and found them safe as used. No peer-reviewed studies show any skincare benefit beyond coloring.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved as a cosmetic colorant in the EU, US (subject to certification), and many other regions. In the US, it is listed under the FDA's color additive regulations for externally applied cosmetics.
- Common uses
- Soaps, Shampoos, Toothpastes, Deodorants, Green-tinted serums and creams
- Environmental note
- The copper content means it should not be released into waterways in large amounts, but typical cosmetic use poses minimal environmental risk.
Good to know
- CI 75810 is also used as a food colorant (E141) in some countries
- It is not the same as natural chlorophyll—the copper modification makes it much more stable
