Description
Desilube 98F — NSF HX-1 Food-Grade EP/AW Lubricant Additive
LuSC-listed inorganic sulfur-phosphorus technology for high-performance greases, metalworking fluids, and environmentally acceptable lubricant (EAL) formulations.
Desilube 98F is a proprietary, high-performance, inorganic sulfur-phosphorus extreme-pressure (EP) and anti-wear (AW) lubricant additive designed for manufacturers of food-grade greases, industrial lubricants, and metalworking fluids.
NSF HX-1 registered and LuSC-listed, Desilube 98F combines load-carrying performance with formulation versatility, supporting the development of food-grade lubricants and environmentally acceptable lubricant (EAL) formulations.
Unlike conventional liquid EP additive packages, Desilube 98F is supplied as a white, free-flowing powder and can be incorporated into a variety of specialty lubricant formulations.

Recommended Applications
Food-Grade Greases, LuSC-Listed and EAL Lubricants, MoS₂, Graphite, and hBN Booster Systems
Desilube 98F provides EP/AW performance for food-grade grease formulations used in food processing equipment, industrial bearings, gears, and other applications requiring high load-carrying capacity.
Environmentally Acceptable Lubricants
As a LuSC-listed additive ingredient, Desilube 98F can support the development of lubricant formulations designed to meet applicable environmental criteria, including selected marine and industrial applications.
Metalworking Fluids
Desilube 98F offers extreme-pressure and anti-wear protection for metal forming, cold heading, hot forging, cutting, and other demanding metalworking processes. It provides an alternative chemistry to conventional chlorinated paraffin EP systems where technically appropriate.
Industrial Greases and Lubricants
Desilube 98F can be evaluated in industrial grease and specialty lubricant formulations where high load-carrying performance and wear protection are required.
Formulation Compatibility and Recommended Dosage
The recommended concentration of Desilube 98F is 1–5% by weight, depending on the application, lubricant base chemistry, operating conditions, and target performance requirements.
Desilube provides laboratory testing, additive compatibility evaluation, and formulation development support to help manufacturers select appropriate treat rates and optimize performance.
Internal testing and formulation guidance are application-specific. Actual results vary by base oil, thickener system, additive package, operating conditions, equipment, and treat rate. Test before scaling.
Frequently Asked Questions
Is Desilube 98F NSF H1 certified?
Desilube 98F is NSF HX-1 registered as a lubricant additive ingredient. HX-1 registration is distinct from NSF H1 registration of a finished lubricant.
Is Desilube 98F suitable for environmentally acceptable lubricants?
Desilube 98F is LuSC-listed and can support EAL formulation development. Final lubricant compliance depends on the complete formulation and the relevant environmental criteria.
Can Desilube 98F replace chlorinated paraffins?
Desilube 98F provides an inorganic EP/AW alternative for selected metalworking and industrial lubricant formulations. Replacement suitability should be established through application-specific performance testing.
What is the recommended dosage?
The typical recommended treat rate is 1–5% by weight. The optimal concentration depends on the lubricant formulation and required performance.
