When concerns were raised about specific forms of nickel in standard Cobalt Titanate, CI Pigment 50 (PG50) in the European Union (EU), The Shepherd Color Company found two high-performance pigment solutions. 


The first route of retaining nickel in the formula, but ensuring that the nickel wasn’t present in the form of concern, yielded Green 10G655. 


This is a standard PG50 specially formulated and produced to meet EU labeling requirements, while maintaining a bright, chromatic green shade that PG50s are known for, and is more chromatic than other inorganic green pigments, such as chrome oxide (PG17). 


A second pathway was to remove nickel from the pigment formulation altogether. 


Shepherd Color developed a bright chromatic green without nickel or chromium and launched it as Green 10G603. This product has a bright and chromatic masstone, excellent tint-strength and it is still classified as a PG50, so it has the same regulatory and chemical inventory approvals and listings.
