Lithol Rubine BK

International Numbering System (INS) for Food Additives: 180
Lithol Rubine BK isn't a common food excipient and likely isn't used in consumable food products. Here's why:

• Colour Index (C.I.): Lithol Rubine BK is often identified by its Colour Index (C.I.) designation, which is a standardized system for naming colours. C.I. numbers designated for food colours typically start with "FD&C" or "E" followed by a number. Lithol Rubine BK doesn't follow this pattern, suggesting it's not intended for food use.
• Industrial Applications: Available information suggests Lithol Rubine BK is a pigment commonly used for industrial applications like colouring plastics, rubber, or inks. It might not be suitable or approved for use in food due to safety concerns.
• Limited Information on Food Use: There's a lack of reliable information on the safety or regulatory approval of Lithol Rubine BK as a food additive.

Conclusion:

Based on available evidence, Lithol Rubine BK is likely not a food excipient. It's more commonly used as a colouring agent in industrial applications. If you encounter this term in relation to food, it's best to treat it with caution and avoid consuming such products.
