Cochineal

Description:
Cochineal, identified by the CAS number 1343-78-8, is a natural dye derived from the cochineal insect, specifically from the female Dactylopius coccus. This substance is primarily composed of carminic acid, which is responsible for its vibrant red color. Cochineal is known for its excellent colorfastness and stability, making it a popular choice in various applications, including food, cosmetics, and textiles. It is often used to impart a red hue to products such as candies, beverages, and dairy items. In addition to its coloring properties, cochineal is also valued for its non-toxic nature, which has led to its acceptance in many organic and natural product formulations. However, it is important to note that some individuals may have allergic reactions to cochineal, leading to its labeling as a potential allergen in food products. Overall, cochineal serves as a significant example of a natural colorant with both historical and contemporary relevance in various industries.

    Cochineal

    CAS:
    <p>Cochineal is a natural dye that is extracted from the female cochineal insect. Cochineal is used in food and cosmetics, and as a red colorant in some pharmaceutical products. The carminic acid present in cochineal forms a stable complex with the anionic groups present in wool or silk, so it is not soluble in water. Cochineal has been shown to have genotoxic activity and can cause mutations at both the base-pairing level and at protein level. Cochineal has also been shown to be cytotoxic against human serum cells and disrupt mitochondrial membrane potential. Its optimum concentration for signal peptide detection by electrochemical impedance spectroscopy (EIS) was found to be 0.1 mM.</p>
