CUYAHOGA FALLS, OH – Emerald Polymer Additives, a division of Emerald Performance Materials, announced that two of its antioxidants, GOOD-RITE^® 3128 and GOOD-RITE^® 3131, have received the NSF HX-1 listing, which allows for their use as ingredients in lubricants with incidental food contact. These products, which can now be used in and around food processing areas, will begin to bear the appropriate NSF symbol on their packaging labels.

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, also based on octyl butylated diphenylamine chemistry, features high nitrogen content and low ash. Ideal for use in a variety of lubricant and grease applications in engines, compressors, gears, hydraulics and turbines,  GOOD-RITE 3128 limits the viscosity build due to oxidation of base stock, control deposits and sludge, and offers good seal protection. This antioxidant is effective at use levels less than one percent.

The NSF Non-Food Compounds Registration Program is a continuation of the USDA product approval program. Approval is based on meeting regulatory requirements, including 21 FDA CFR for appropriate use, ingredient and labeling review.

GOOD-RITE 3128 and GOOD-RITE 3131 are manufactured in the company’s ISO-9001-certified facility in Akron, OH. Emerald’s GOOD-RITE brand covers a range of specialty aminic and phenolic antioxidants based on technologies with a 70+-year track record.
