What Is Pigment Green 7?
When used in colourants, pigment green 7 is not known to cause allergic reactions. However, it has been linked to mutagenic effects. The International Agency for Research on Cancer (IARC) lists pigments like Pigment Green 7 as possible carcinogens. As a result, pigments like pigment green 7 are often only used in industrial products like paint and plastic. Some countries regulate pigments such as pigment green 7 due to their potential health risks or because they have been shown to damage DNA when exposed to light for extended periods.
For example, Chinese legislation requires the labelling of all substances that damage DNA or cause cancer over a certain threshold dose. Unfortunately, pigment green 7 does meet these requirements. While there is no conclusive evidence that pigment green 7 causes cancer in humans, there is enough data to suggest caution should be taken with its use. In addition to being potentially harmful if inhaled or ingested, pigment green 7 can also cause skin irritation if it comes into contact with your skin. It’s best to avoid direct contact with pigment green 7 unless you need it for your product! If you do choose to use pigment green 7 in your product, please be sure to follow any local regulations regarding its safe handling and disposal.
potassium nitrate, copper sulphate, potassium chloride, calcium chloride and water. Potassium nitrate will react with copper sulphate and water to form copper (II) acetyl nitrate, while copper (II) acetylnitric acid will act with potassium chlorate and calcium chloride to produce potassium perchlorate plus cupric (II) acetyl nitrate. The addition of a solution of sodium hydroxide to cupric (II) acetyl nitrate gives a green pigment of the formula CHCuN(OCH). This can be converted into pigment green 7 by reaction with phthalic anhydride or maleic anhydride. The pigment is insoluble in water but soluble in alcohols, ethers and glycols. The pigment is used as a paint pigment for artists’ paints such as poster paints and also used in printing ink. It is used as a dyeing agent for cotton fabrics. Pigment Green 7 Manufacturer
