Pigment Green 7: Compliance.
Pigment Green 7, or PIGMENT GREEN 7 used as an artificial colour in food, drugs, and cosmetics since it was created in the 1950s. But the safety of Pigment Green 7 has been called into question since the 1970s when researchers linked the compound to lung cancer in animal studies (along with many other problems). In 2009, the FDA and Health Canada both banned its use in food products sold in those countries, but there are still some products on the market that contain it.
What is Pigment Green 7?
Pigment Green 7 (PG7) a pigment with a copper-phthalocyanine core and sodium sulfonate groups. The chemical formula for PG7 C20H18CuN4NaO8S4. This pigment developed by CIBA, Ltd., Basle, Switzerland. It is similar to PG36 but differs in structure by having both sulfonate groups in each of its molecules. The C.I. pigment designation for PG7 is Pigment Green 7; CAS Registry No. 6358-97-0; EINECS No.
The Uses of P.G.7.
Due to its deep colouring pigment, it commonly used in plastics and textiles. The most common uses of Pigment Green 7 include (1) Paints, rubber/plastic/textile fibres, leathers and paper products; (2) PVC coatings for steel and powder coatings for plastic; (3) textiles; (4) Plastic films and blow moulding applications. Also referred to as P-Green or PG7. Most colours fade over time which seen in paints, plastics or even everyday clothing. The fading that occurs in these items comes from exposure to different types of light which affect a chemical process called pigment green 7 manufacturer in india.
This process involves the absorption of ultraviolet radiation by molecules within a material resulting in physical changes such as discolouration, cracking or breaking down into smaller pieces. Pigment Green 7 is one of many chemicals known to cause photodegradation when exposed to UV radiation. Because of its use primarily in plastics and textiles, more research has been done on how it reacts with UV radiation than other pigments like titanium dioxide which mainly used in paints. Studies have shown that when exposed to UV radiation under laboratory conditions P-Green 7 will break down at roughly 200 nanometers per hour when compared with titanium dioxide’s 100 nanometers per hour rate under similar conditions.
Restrictions on Use.
The colour additive, Pigment Green 7 (PG7), shall not be used in oral drug products except those in which it is an integral part of a finished dosage form. In such dosage forms, PG7 shall conform to all applicable provisions of 314.30 through 314.55 and 572.10 of 21 CFR Chapter I, except that PG7 may be used at levels up to 1%. The safety and effectiveness of PG7 have not been established for topical application. When PG7 is present in eye area products or when it is combined with other materials to create lip colour products, additional data and information are required before marketing approval as described below.
See Section IV for more detailed information on requirements about the use of PG7 in these types of products. If PG7 is incorporated into lipstick, one of three things must occur before marketing approval: FDA received notification from you that you intend to market your product within 30 days after you receive notification from FDA. FDA must have determined either that there are no safety or efficacy questions about your product. you must submit clinical and nonclinical data demonstrating that your product does not cause serious adverse effects when applied topically.
