Indigo Carmine

Immerse your industrial and technical projects in the profound depth of blue with our Indigo Carmine CI 73015 Non-FDA Industrial Dye Powder. Known also by its E-number E-132 and CAS 860-22-0, this high-performance synthetic indigoid dye is celebrated for its intense blue coloration and exceptional solubility in water.

Crucially, this product is explicitly designated as “Non-FDA” for a fundamental reason: While Indigo Carmine (FD&C Blue No. 2) is approved by the U.S. Food and Drug Administration (FDA) for food, drug, and cosmetic use, that approval applies only to specifically certified grades. This particular “Non-FDA” product is NOT manufactured, certified, or intended to meet the stringent regulatory requirements for use in food, drug, or cosmetic products within the United States. For sales within the U.S. and under the “Non-FDA” classification, this product is NOT suitable for any FDA-regulated applications. Our Indigo Carmine Industrial Dye Powder is specifically formulated and packaged for industrial, technical, and artistic applications where the rigorous standards for human consumption or topical contact are not applicable, and where FDA certification is explicitly absent.

Understanding Non-FDA Indigo Carmine: The Industrial Blue Standard Indigo Carmine (chemical formula C16H8N2Na2O8S2) is a robust and stable dye that provides a consistent, deep blue hue. As a “Water Soluble Color,” it disperses readily and uniformly in aqueous solutions, making it an efficient choice for various industrial processes. This Non-FDA Industrial Grade offers a powerful yet cost-effective solution for achieving striking blue effects in applications that fall outside the purview of food, drug, or cosmetic regulations. Its reliability, strong tinting power, and color stability under various processing conditions make it an invaluable asset for a wide spectrum of technical and manufacturing needs.

Bringing Deep Blue to Industrial and Creative Applications The versatility of our Indigo Carmine CI 73015 Non-FDA Industrial Dye Powder makes it an excellent choice for numerous non-regulated applications:

• Textile & Fabric Dyeing: Imparting rich, deep blue shades to a variety of fibers and fabrics in industrial dyeing processes.
• Paper & Pulp Industry: Providing intense blue coloration for paper products, including specialty papers, cardboard, and decorative materials.
• Ink Manufacturing: Utilized in the creation of deep blue inks for printing, markers, and other graphic arts applications.
• Cleaning Product Formulations: Adding a distinctive blue color to industrial cleaning agents, detergents, and household chemical products (emphasizing non-cosmetic use).
• Educational & Artistic Pursuits: An ideal component for scientific demonstrations, art projects, crafting, and theatrical productions where a powerful, non-ingestible blue dye is required.
• Laboratory & Research: Employed as a general chemical reagent, indicator (e.g., redox indicator in analytical chemistry), or staining agent in various non-biological laboratory procedures.

Safety First: Responsible Handling of Industrial Dyes As an industrial-grade chemical, strict adherence to safety protocols is absolutely essential when handling Indigo Carmine CI 73015 Non-FDA Industrial Dye Powder. Always wear appropriate personal protective equipment (PPE), including chemical-resistant gloves, eye protection (safety goggles or a face shield), and a dust mask or respirator, to prevent inhalation of airborne particles and direct skin/eye contact. Work in a well-ventilated environment to minimize exposure. It is imperative to prevent ingestion, direct skin contact, and eye contact at all times, especially given its non-FDA status for sensitive applications. Store this product in a tightly sealed container in a cool, dry, and well-ventilated area, away from incompatible materials, moisture, and direct sunlight. Always consult the product’s Safety Data Sheet (SDS) for comprehensive information on safe handling, storage, and emergency procedures. Proper waste disposal, in accordance with local regulations for chemical waste, is also a critical responsibility.

FAQs:

Q: Is this Indigo Carmine CI 73015 product approved for use in food, drugs, or cosmetics in the US? A: No, absolutely not. While certified grades of Indigo Carmine (FD&C Blue No. 2) are FDA-approved for food, drug, and cosmetic use, this specific product is explicitly designated as “Non-FDA Industrial Dye.” This means it is NOT manufactured or certified for any use in food, drugs, or cosmetics within the United States and is unsuitable for human consumption or direct skin contact.

Q: What does “Non-FDA” specifically mean for this Indigo Carmine, given that FD&C Blue No. 2 is FDA-approved? A: For Indigo Carmine, the “Non-FDA” designation signifies that this particular product is an industrial/technical grade which does not meet the stringent purity, manufacturing, and certification requirements necessary for FDA approval as FD&C Blue No. 2. It is therefore intended exclusively for non-regulated industrial applications, distinct from its food/drug/cosmetic counterparts.

Q: What are the appropriate uses for Indigo Carmine Non-FDA Industrial Dye Powder? A: This industrial-grade Indigo Carmine is ideal for coloring textiles, paper, and plastics. It’s also widely used in the production of industrial inks and paints, for adding color to certain cleaning products, and in various artistic, crafting, and educational projects where a rich, water-soluble blue dye is needed, and where human ingestion or direct skin contact is strictly avoided. It can also function as a redox indicator in laboratory settings.

Q: What safety precautions are mandatory when handling this industrial dye? A: When handling Indigo Carmine Non-FDA Industrial Dye Powder, it is critical to wear appropriate personal protective equipment (PPE), including chemical-resistant gloves, eye protection (safety goggles), and a dust mask or respirator. Work only in a well-ventilated area. Absolutely avoid inhalation of dust, ingestion, and any contact with skin or eyes. Always refer to the product’s Safety Data Sheet (SDS) for comprehensive safety guidelines.

Q: Is Indigo Carmine (E-132) used in food coloring in other parts of the world? A: Yes, Indigo Carmine, designated as E-132, is approved as a food additive in some regions outside the U.S., notably within the European Union, albeit with specific usage restrictions and acceptable daily intake (ADI) limits. However, this particular product is designated “Non-FDA” for the US market and should not be used in any food, drug, or cosmetic application regardless of international regulations.
