Description
Desilube 88 — NSF HX-1 Food-Grade EP/AW Lubricant Additive
LuSC-listed inorganic sulfur-phosphorus technology for food-grade greases, metalworking fluids, industrial lubricants, and environmentally acceptable lubricant (EAL) formulations.
Desilube 88 is a proprietary inorganic sulfur-phosphorus extreme-pressure (EP), anti-wear (AW), and anti-friction (AF) lubricant additive for manufacturers formulating food-grade greases, metalworking fluids, industrial oils, and EAL lubricant systems.
Desilube 88 is NSF HX-1 registered and LuSC-listed, supporting lubricant manufacturers developing H1 food-grade lubricant formulations, EU Ecolabel-oriented formulations, and other environmentally responsible lubricant products.
Unlike dark solid lubricants, Desilube 88 is supplied as a white, free-flowing powder. It can be evaluated as an EP/AW additive, a white solid-lubricant alternative, or a performance booster with MoS2, graphite, hBN, and compatible additive packages.
Key Benefits of Desilube 88
- NSF HX-1 registered ingredient: Suitable for evaluation in food-grade lubricant formulations, subject to applicable registration limits and final-formulation review.
- LuSC-listed additive: Supports lubricant manufacturers developing EAL and EU Ecolabel-oriented formulations.
- Extreme-pressure and anti-wear support: Designed for high-load grease, oil, and metalworking applications.
- White powder form: Useful where black solid additives such as graphite or MoS2 are not preferred.
- Water-based formulation option: Can be evaluated in water-dilutable EP systems and metalworking fluid packages.
- Chlorinated paraffin alternative: Provides a non-chlorinated EP/AW chemistry option where application testing confirms suitability.

Recommended Applications
Food-Grade Greases and Lubricants
Desilube 88 can be evaluated in food-grade grease and lubricant formulations for bearings, gears, chains, packaging lines, bottling equipment, and other high-load food processing applications where NSF HX-1 additive ingredients are required.
Environmentally Acceptable Lubricants and EAL Formulations
As a LuSC-listed additive ingredient, Desilube 88 can support EAL formulation development. Final lubricant compliance depends on the full finished formulation and the applicable environmental criteria.
Metalworking Fluids
Desilube 88 can be evaluated in water-based and oil-based metalworking fluids for cutting, forming, rolling, drawing, and severe boundary-lubrication applications.
Industrial Greases and Specialty Lubricants
Desilube 88 can be used in lithium, aluminum complex, mineral-oil, and specialty grease systems where white EP/AW chemistry is preferred over black solid lubricants or chlorinated EP chemistry.
Formulation Compatibility and Recommended Dosage
Typical Desilube 88 treat rates are 1-10% by weight depending on formulation type, base chemistry, operating conditions, required EP/AW performance, and compatibility with the complete additive package.
For water-based systems, Desilube 88 can be evaluated in concentrates and diluted systems; brochure data includes a 2% concentrate diluted 1:20 to 0.1% active Desilube 88 at pH 7-8.
Desilube provides laboratory testing, additive compatibility evaluation, and formulation support to help manufacturers select treat rate and validate application-specific performance.
Frequently Asked Questions
Is Desilube 88 NSF H1 certified?
Desilube 88 is NSF HX-1 registered as a lubricant additive ingredient. HX-1 registration is different from NSF H1 registration of a finished lubricant.
Is Desilube 88 LuSC listed?
Yes. Desilube 88 is LuSC-listed as an additive ingredient and can support lubricant manufacturers developing EAL or EU Ecolabel-oriented formulations.
Can Desilube 88 be used in water-based metalworking fluids?
Yes, Desilube 88 can be evaluated in water-based formulation systems. Compatibility, stability, pH, corrosion protection, and final performance should be confirmed in the complete formulation.
Can Desilube 88 replace MoS2, graphite, or chlorinated paraffins?
Desilube 88 provides a white inorganic EP/AW chemistry option for selected formulations. Replacement suitability must be confirmed through application-specific testing because each lubricant system has different base oils, thickeners, co-additives, and operating conditions.
