Q Which surfactants are effective for waterborne packaging inks where FDA compliance for indirect food contact is desired?
A Whether the substrate is coated paper for candy wrappers or high-slip flexible film for potato chip, bags, good flow and leveling is required to achieve excellent print results. Surfynol[R] 400 Series surfactants and Surfynol SE-F surfactant Surfactant Definition
Surfactant is a complex naturally occurring substance made of six lipids (fats) and four proteins that is produced in the lungs. It can also be manufactured synthetically.

See: Cost and Freight 175.105, 175.300, 176.170 and 176.180 regulations, making them ideal for waterborne packaging inks involving indirect food contact. The Surfynol 400 Series consists of four products of varying levels of ethoxylation, offering a broad range of performance. Surfynol 420 surfactant offers the best combination of wetting and defoaming while Surfyol 440 surfactant 465 and 485 surfactants are completely miscible miscible /mis·ci·ble/ (mis´i-b'l) able to be mixed.
mis·ci·ble
adj.
Capable of being and remaining mixed in all proportions. Used of liquids. in water. Surfynol SE-F surfactant forms stable emulsions in without generating foam. Whatever the desired performance of the ink, these surfactants offer the best combination of wetting and defoaming without negatively affecting gloss or degrading polymeric printing plates.
