Product Details


Sulfurized Fatty Acid Ester

Light Color | Low Odor | Superior Oil Solubility

  • CAS Number: 72102-30-8 (Representative)  
  • Product Category: Extreme Pressure (EP) & Oiliness Agent

In the competitive landscape of industrial lubricant manufacturing, performance is no longer enough. Modern B2B buyers demand additives that are as pleasant to handle as they are effective. 

Chemost’s Sulfurized Fatty Acid Ester is engineered for blenders who refuse to compromise between high-load protection and aesthetic stability.


【Product Capability Profile】

Our sulfurized ester is a high-purity sulfur-based additive designed specifically for the formulation of premium metalworking fluids and industrial lubricants. It functions as both a Sulfur Additive for extreme pressure and a high-performance Oiliness Agent.

Distinctive Advantages for the Blender:

  • Aesthetic Excellence: Unlike traditional sulfurized fats that are dark and pungent, our ester is characterized by a light color and minimal odor, ensuring the finished lubricant remains visually appealing and operator-friendly.
  • Precision Anti-Wear (AW): Forms a resilient, low-friction sacrificial film on metal surfaces, significantly reducing wear in boundary lubrication regimes.
  • High Oil Solubility: Rapidly integrates into mineral oils (Group I, II, III) and synthetic esters, ensuring a stable, non-separating formulation even during long-term storage.
  • Inactive Sulfur Profile: Designed to be non-corrosive to yellow metals at lower temperatures, providing a wide "safety window" for multi-metal machining applications.

【Strategic Application Guidance】

This additive is specifically optimized for high-performance industrial environments:

1. Metalworking Fluids (MWF)

Application: Neat oils for broaching, tapping, and heavy-duty gear cutting.

Benefit: Provides the necessary "oiliness" to improve surface finish and extend tool life in stainless steel and alloy machining.

2. Industrial Gear Oils

Application: High-load industrial gearboxes.

Benefit: Acts as a secondary EP agent to boost the performance of phosphorus-based systems without increasing acidity.

3. Hydraulic & Slideway Oils

Application: Precision machine tool slideways.

Benefit: Eliminates "stick-slip" behavior due to its excellent adsorption on metal surfaces.

Recommended Dosage Levels:

  • General Machining: 2% – 8%
  • Heavy Duty Cutting: 10% – 20%
  • Industrial Gear Oils: 0.5% – 3%

【Compatibility & Integration】

Our Sulfurized Fatty Acid Ester is designed to be "Formulation Friendly." It exhibits strong synergistic effects when paired with:

Phosphorus-based AW agents (like ZDDP or TPPT): Enhancing the overall load-carrying capacity through sulfur-phosphorus synergy.

Corrosion Inhibitors: Compatible with both oil-soluble and water-dispersible rust inhibitors.

Chlorinated Paraffin Alternatives: An excellent component for blenders moving toward chlorine-free, environmentally responsible formulations.


【Quality Assurance & Documentation Support】

As a dedicated B2B supplier, Chemost understands that your factory's QC process starts with our documentation. We provide a complete transparency package for every order:

  • TDS (Technical Data Sheet): Comprehensive application data and chemical properties.
  • MSDS (Material Safety Data Sheet): Fully compliant with international chemical safety standards.
  • COA (Certificate of Analysis): Batch-specific verification of sulfur content, color, and viscosity.

【FAQ: Expert Insights】

Q: Why is "low odor" so important for this specific additive?

A: In metalworking environments, operator comfort is a major concern. Traditional sulfur additives release a strong, unpleasant smell when heated during machining. Our sulfurized ester is refined to remove these volatile odor-causing compounds, making the workplace safer and more comfortable.

Q: Is this product suitable for use on copper and brass?

A: Yes. Because the active sulfur content is strictly controlled (typically <1%), it is safe for copper alloys at moderate temperatures. However, for extremely high-temperature copper work, we recommend a copper deactivator as a precaution.

Q: Can I use this in water-soluble cutting fluids?

A: This specific grade is oil-soluble. For water-based applications, it must be emulsified using an appropriate surfactant package, which we can also provide advice on.
