The permitted application, concentration and product type can vary between countries, so manufacturers should always check the regulations applicable to their target market.

Is Acid Red 52 a Food Colour?
This is an important question for manufacturers and buyers because the regulatory status of Acid Red 52 varies between countries.
Acid Red 52 is also known as Food Red No. 106 in Japan, where it has a recognised food-additive use under the applicable Japanese requirements. However, its food-colour status is different in other markets.
Therefore, Acid Red 52 should not be described as a universally approved food colour. Food-colour regulations are country-specific and can also depend on the food category, permitted concentration and product specification.
Manufacturers planning to use or import Acid Red 52 for food applications should verify the latest regulations of the destination country before commercial use.
Regulatory Compliance of Acid Red 52
The regulatory status of Acid Red 52 (CI 45100 / CAS No. 3520-42-1) depends on several factors, including the country, product category, intended application, concentration and grade of the colour.
A colour that is permitted for a particular application in one country is not automatically approved for the same application in another country. For this reason, manufacturers should confirm the current requirements of the destination market before using Acid Red 52 in a finished product.
For cosmetic applications, Acid Red 52 is recognised as CI 45100 and is subject to specific requirements in certain markets. For example, the European Union regulates cosmetic ingredients under Regulation (EC) No. 1223/2009, including specific conditions for certain uses of Acid Red 52.
For food applications, the regulatory position is different and must be assessed separately. Acid Red 52 is associated with Food Red No. 106 in Japan, while its use as a food colour is not permitted in several other major markets.
Required Documentation for Acid Red 52
Appropriate documentation is required depending on product grade, application and customer needs. Depending on the application, the available documentation may include:
- Certificate of Analysis (COA)
- Technical Data Sheet (TDS)
- Safety Data Sheet (SDS)
- Product specification
- Batch information
- Purity and identity data
- Heavy metal and impurity information, where applicable
- Regulatory or compliance statements
- Application-specific documentation
This documentation provides manufacturers with the information to help assess the technical features of the product and determine whether it is suitable for their intended use and target market.
