Chemical Profile of Carmine

Carmine (CAS 1390-65-4) is derived from carminic acid, a substance extracted from certain species of scale insects, most notably the cochineal insect. Its chemical formula is C22H20O13, with a molecular weight of approximately 492.39 g/mol. Key chemical properties include its appearance as a red powder and its solubility. Carmine is soluble in alkali solutions, ammonium hydroxide, and slightly soluble in hot water, but generally insoluble in cold water and dilute acids. Its melting point is around 138-140°C (with darkening). These properties dictate its suitability for various formulation processes. As a supplier, we ensure our Carmine meets precise specifications for these chemical attributes.

Industrial Applications: From Cosmetics to Pharmaceuticals

The versatility of Carmine makes it a cornerstone ingredient across several key sectors. In the cosmetics industry, it provides a natural, vibrant red for lipsticks, blushes, and eyeshadows, and is often sought by makeup manufacturers who prefer natural ingredients. The food and beverage industry utilizes Carmine (often designated E120) as a natural colorant in products like yogurts, candies, and juices, valuing its stability during processing and storage. For researchers and technicians, Carmine is a vital component in histology, serving as a stain for nuclei and glycogen.
