The Shepherd Color Co. Meets Regulatory Challenges With Technical Expertise
CINCINNATI — When concerns were raised about specific forms of nickel in standard cobalt titanate, CI pigment 50 (PG50) in the EU, The Shepherd Color Co. deployed its expertise in technical, analytical and regulatory areas to find 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).
