PFAS-Free Cookware Using Shepherd Color Pigments

What’s Cookin’ is Color!

Regulations around the use of PFAS chemicals impact not only them, but related chemistries and products that have to be reformulated. The Shepherd Color Company’s Complex Inorganic Color Pigments (CICPs) are PFAS-free and their inherent stability helps materials have weatherable color, resistance to chemicals, are non-migratory, and high-heat stable.

One key area impacted by reformulations due to PFAS issues is cookware. The change from fluoro-containing to inorganic coatings formulations play to the inherent strengths of Shepherd Color’s highly-engineered pigments, specifically the inherent high-heat stability. Our pigments are calcined at high temperatures, up to 1250C/2300F to resist oxidation and degradation at temperatures that would destroy organic, or even other inorganic pigments. This stability means that they can stand up to the production process temperatures and in-use temperatures. Being inorganic in chemistry, they formulate well in inorganic binder-based coatings systems.

A wide range of our pigments are approved or compliant with:

• BfR
• FDA Food Packaging
• China GB9685

We also have several Shepherd Color exclusive FDA Food Contact Notification (FCN) approvals for unique colors. Our Black 20F944 makes dark, jet-black colors that are not based on chromium while our green-shade cobalt Blue 10F545 complements the red-shade cobalt blues (PBl28) like Blue 214, Blue 385, Blue 10C595 and the highly chromatic Blue 20G599. Shepherd Color’s FCN for the Green 10F687 opens the festive blue-green color space. The range of pigment colors Shepherd Color provides extends past the green chromium oxide (PG17) with Green 10G655 and Green 10G603 (PG50).

Our Brown 19FDA has been a popular earthy color for decades in cookware coatings while our wide range of titanate-based pigments (PY53 and PBr24) covers the green and red-shade yellow color space.

Perhaps the most popular color for cookware is Black 430 with its jet masstone color, blue-shade tints, and pure manganese-free formulation for inclusion in the FDA compliant PBk28 designation.
