Optimizing Raw Material Cost in Metalworking Fluids with Oleic Acid

Problem

A lubricant manufacturer producing metalworking fluids faced increasing pressure to control raw material costs while maintaining product performance. The formulation relied heavily on high-purity oleic acid as a key component in the emulsification and lubrication system.

However, the procurement team was sourcing Oleic Acid 90%, which exceeded the purity requirement needed for the formulation. Rising feedstock prices significantly impacted production margins.

The challenge for the manufacturer was to reduce material costs without compromising:

• Lubrication performance

• Emulsion stability

• Oxidation resistance

The R&D team required a technically viable alternative that would maintain formulation stability while improving cost efficiency.

Ideation

A technical review of the formulation indicated that the metalworking fluid system did not require the higher purity threshold of Oleic Acid 90%.

Instead, Oleic Acid 80% could provide sufficient performance while delivering better cost efficiency.

Key evaluation parameters included:

• Lubricity performance in metal surface contact

• Emulsion stability in water-based systems

• Oxidation behavior influenced by iodine value

After assessing the formulation tolerance, we recommended switching to Oleic Acid 80% with controlled iodine value specifications. This maintained lubrication functionality while optimizing raw material utilization.

The recommendation also included ensuring consistent sourcing to avoid variability that could impact emulsion stability.

Outcome

Following the formulation adjustment and raw material transition, the manufacturer successfully optimized production costs while maintaining product quality.

Results included:

• 8–10% reduction in raw material cost

• Maintained lubrication performance in metalworking applications

• Stable emulsion behavior in finished fluids

• Improved profit margin flexibility for the final product

This strategic adjustment allowed the manufacturer to remain competitive while preserving product performance standards.
