Experimental Data: Migration Performance of Our Iron Oxides in Five Food Simulants — Oil, Acid, Alcohol, and More

Introduction: Data, Not Claims

In the world of food contact compliance, claims are not enough. Regulators demand data. Customers demand proof. And the most critical data point for iron oxide pigments in food contact applications is specific migration — how much of a substance transfers from the pigment into food under intended use conditions.

This article presents actual migration test data for Hangzhou Hangyan Technology's food-grade iron oxides (CI 77491 red, CI 77492 yellow, CI 77499 black). All tests were conducted by ISO 17025 accredited laboratories following EU (EU) 10/2011 methodology.

We share this data not as marketing — but as transparency. Food manufacturers deserve to know exactly what they are buying.
