Emerald Polymer Additives recently announced that two of its antioxidants have received the NSF HX-1 listing, allowing for their use as ingredients in lubricants with incidental food contact. Good-Rite 3128 and 3131 can now be used in and around food-processing areas and will begin to bear the appropriate NSF symbol on their packaging labels.
The NSF Non-Food Compounds Registration Program is a continuation of the U.S. Department of Agriculture’s product approval program. Approval is based on meeting regulatory requirements, including the Food and Drug Administration’s regulations for appropriate use, ingredient and labeling review.
“Emerald has a lot of expertise when it comes to products used in food and food-contact applications, and as a result has a thorough understanding of the various manufacturing and regulatory requirements,” said John Zuppo, general manager of lubricant and plastic antioxidant product lines for Emerald Polymer Additives. “Other Emerald divisions offer a wide range of direct food additives, food-processing aids and other products for indirect food contact, such as antimicrobials and preservatives, flavor and fragrance ingredients, colorants, defoamers and polymers. Obtaining this important NSF HX-1 listing adds to the range of approved food-contact antioxidants in our portfolio.”
Based on octyl-butylated diphenylamine chemistry, Good-Rite 3131 is formulated to prevent discoloration/scorch by providing thermo-oxidative stabilization of oils, lubricants, polyols, elastomers and adhesives. As an easy-to-use liquid with low volatility, it offers high activity at low use levels (less than 0.5 percent).
Good-Rite 3128, which is also based on octyl-butylated diphenylamine chemistry, features high nitrogen content and low ash. It is ideal for use in a variety of lubricant and grease applications in engines, compressors, gears, hydraulics and turbines. The antioxidant provides seal protection and limits the viscosity build due to oxidation of base stock, control deposits and sludge.
Good-Rite 3128 and 3131 are manufactured in Emerald’s ISO-9001 certified facility in Akron, Ohio. For more information, visit www.emeraldmaterials.com.
