What is pigment green 7?
Pigment Green 7 has been used in paints, ceramic glazes, inks, and other materials since the 1960s, but where does it come from? When someone says Pigment Green 7 (or PG7), they’re referring to a mixture of copper chromium green pigments that have been combined with a nickel mordant. In this article, we’ll explore what Pigment Green 7 is and how it’s made. You’ll also learn some uses of this synthetic dye, which was developed as an alternative to chrome yellow pigments made from lead chromate.
The History
Pigment green 7 has a long history, with its discovery credited to chemist Heinrich Caro in 1820. Caro identified several common colorants, but his work was not immediately adopted by commercial manufacturers because of limited methods for producing synthetic dyes. The manufacturing method was improved by German chemist Carl Graebe, who developed an inexpensive process for producing pigment green 7. This enabled more widespread adoption of pigment green 7 as an industrial colorant and dye replacement. As scientists learned more about Pigment Green 7, they began using it to study deeper properties of human anatomy. Research is ongoing today in applications including nuclear medicine imaging and experimental medical therapies like targeted cancer treatment.
The Manufacturing Process
Pigment Green 7 is an inorganic pigment used in various fields of industry. Pigment Green 7 is a kind of phthalocyanine pigment, which belongs to triarylmethane series. As other pigments, Pigment Green 7 may be also called Poly P.G.7 or Polyphthalocyanine green G (PG7). This pigment can be made by using phthalocyanine compound as raw material with some special processing methods in factories. The process includes two steps of synthesis and purification. The main raw materials for manufacturing Pigment Green 7 are copper phthalocyanine, sodium hydroxide solution and concentrated sulfuric acid solution. First step: To make copper phthalocyanine from copper sulfate solution and sodium hydroxide solution through synthesis reaction, we need to prepare two solutions firstly.
More About Pigment Green 7
Pigment Green 7 is a green or cyan pigment, which is why it’s sometimes referred to as Pigment Green 1. It ranges in hue from blue-green to yellow-green and is widely used in oil paints, plastics, textiles, food coloring and many other applications. The molecular structure of Pigment Green 7 actually closely resembles that of chlorophyll, which explains its presence in certain vegetables like spinach. Although slightly more rare than some pigments like carbon black or titanium dioxide, Pigment Green 7 remains extremely popular because it’s relatively inexpensive while still producing vibrant colors.

Applications Of Pigment Green 7
Found in plastics, paints, wallpaper and other products, Pigment Green 7 is also used in solar cells. The dye may seem simple—dye molecules are composed of carbon atoms connected to hydrogen or hydroxyl groups—but it plays a critical role in many products. Pigment green is added to paper for color consistency; it’s used as a pH indicator; it even helps make artificial leather. And because Pigment Green 7 has a very low toxicity profile, almost any surface can safely hold traces of pigment green without worry about environmental contamination.
Safety Considerations Of Pigment Green 7
Pigment Green 7 is made from copper, chlorine, and ammonia. Copper is a heavy metal that is not easily broken down by natural processes in your body. This means it can build up over time, possibly causing harm to your organs (especially your liver) or leading to major health problems like Alzheimer’s disease or arthritis. The color pigment also contains chlorine which has toxic properties of its own. Again, at high enough levels of exposure, it can cause organ damage (the kidneys), respiratory issues, burning skin rashes, cancer, or even blindness if left untreated over an extended period of time. Finally there’s ammonia which is a caustic substance that burns skin and damages eyes when exposed in high amounts.
Disposal Of Paint Containing Pigment Green 7
Most paint waste containing pigment green 7 can be disposed of with regular household waste. Pigment Green 7 Manufacturer is best for people. Check with your local city ordinances for specific guidelines on paint disposal. However, many cities have strict regulations regarding disposal of any chemical-based products, so always check first to avoid fines or possible legal action. For detailed information on safe handling and disposal of any chemicals, refer to product labels and Material Safety Data Sheets (MSDS). In addition, please follow these simple tips.
