Ci 75810

Deep within the chlorophyll-rich cells of green plants lies the source of CI 75810, a pigment that, in its natural form, is responsible for the vibrant green hues we see in leaves and grasses. Chemically, this ingredient is a copper derivative of chlorophyll, specifically known as copper chlorophyllin, which is produced by saponifying chlorophyll extracts from plants like alfalfa, nettles, or mulberry leaves. The addition of copper stabilizes the molecule, transforming it from the somewhat fragile natural chlorophyll into a more robust, water-soluble compound that resists fading when exposed to light or heat. This semi-synthetic process retains the fundamental porphyrin ring structure of chlorophyll, giving CI 75810 its characteristic green color while enhancing its functional versatility in cosmetic formulations.

In cosmetics, CI 75810 serves primarily as a cosmetic colorant, where its mechanism is purely physical—it absorbs and reflects specific wavelengths of visible light to impart a green tint to products. Formulators value it for its natural origin and stability compared to other green pigments, and it is typically used at concentrations between 0.01% and 1% depending on the desired intensity. Beyond coloring, this ingredient also functions as a deodorant, a lesser-known but scientifically supported role. Copper chlorophyllin can bind to and neutralize certain odor-causing compounds, such as amines and sulfur-based molecules, through a process called chelation, where the copper ion forms complexes with these malodorous substances, rendering them less volatile and noticeable. This dual action makes it a unique addition to products aiming for both aesthetic appeal and functional odor control.

The benefits of CI 75810 extend beyond its visual appeal, with the deodorant property being particularly noteworthy for those seeking natural alternatives to traditional antiperspirants. Studies suggest that copper chlorophyllin can reduce body odor by up to 85% in some formulations, though the evidence is largely based on older research and may vary with product pH and concentration. For the skin, this ingredient is generally considered non-irritating and may offer mild antioxidant activity due to its porphyrin structure, which can scavenge free radicals to a limited extent. However, its primary cosmetic benefit remains its ability to provide a stable, natural green color that does not stain the skin permanently, making it a favorite in natural and organic product lines where synthetic dyes are avoided.

CI 75810 is well-suited for most skin types, including sensitive and reactive skin, as it rarely causes irritation or allergic reactions—a significant advantage over some synthetic green colorants like FD&C Green No. 3. It pairs harmoniously with a wide range of other cosmetic ingredients, including water-based formulations, emulsions, and anhydrous products, though it may lose its vibrant green hue in highly acidic or alkaline environments (optimal pH range is 5–7). One limitation to note is that while it functions as a deodorant, it does not prevent sweating like an antiperspirant; it simply masks or neutralizes odor, so it works best in combination with other odor-control ingredients. Additionally, because it is derived from plants, those with extreme allergies to specific botanical sources (e.g., alfalfa) should check the product's origin labeling, though such reactions are exceedingly rare.

When shopping for products containing CI 75810, you'll typically find it listed as CI 75810 or copper chlorophyllin on ingredient labels, often appearing near the end of the list due to its low usage concentrations. In practice, this ingredient imparts a soft, natural green tint to creams, lotions, soaps, and even toothpaste, where it is also used for its breath-freshening properties. A fascinating fact: copper chlorophyllin is sometimes used internally as a dietary supplement for its potential deodorizing effects on bodily fluids, though in cosmetics it is strictly for topical application. Its stability and safety have earned it approval from regulatory bodies like the FDA and EU CosIng, making it a reliable choice for formulators who want to combine color with a subtle, natural deodorizing benefit. Whether in a green-tinted moisturizer or a natural deodorant stick, CI 75810 offers a rare blend of aesthetic and functional utility that bridges the gap between nature and science.
