What Is Stearic Acid?
Stearic acid (octadecanoic acid, C18H36O2, CAS 57-11-4) is a saturated C18 fatty acid produced from natural fats and oils through fat splitting, hydrogenation, and distillation. Commercial stearic acid is typically a blend of stearic (C18) and palmitic (C16) acids; a range of industry-standard purities are available to fit your applications. It is widely used in rubber and plastics processing, lubricants, textiles, candles, soaps and detergents.
Sustainable Sourcing
Choose stearic acid grades with the feedstock and composition your application requires. Emery Oleochemicals offers the following options:
| Stearic acid grade | Available feedstock | Grade designation |
|---|---|---|
| 43% | Vegetable-based | Triple-pressed |
| 50% | Vegetable- or tallow-based | Triple-pressed |
| 65% | Vegetable- or tallow-based | SA65% / C18:65% |
Our vegetable-based, triple-pressed grades are available under the RSPO Mass Balance supply chain model, supporting responsible palm sourcing. Mass Balance certification tracks certified palm material through the supply chain; it does not apply to tallow-based products. Learn more about Emery’s RSPO Mass Balance supply chain certification.

Stearic Acid FAQs
What is the difference between vegetable and tallow stearic acid?
Vegetable stearic acid is derived from vegetable oils, while tallow stearic acid is derived from animal fats. When choosing between them, compare the grade’s technical specifications with your formulation requirements, then consider any feedstock sourcing requirements.
Explore Emery’s vegetable fatty acids and tallow fatty acids for product specifications and application information.
How do I choose the right stearic acid grade?
Start by matching the grade’s specifications to your application. Compare C16/C18 fatty acid composition, acid value, iodine value, titer, and color against your formulation and processing requirements. Then confirm any feedstock or certification requirements.
Contact our technical team to discuss your application and request a technical data sheet or sample.
How can I confirm sourcing and certification options for stearic acid?
Confirm the feedstock source and any required certification for your selected grade with Emery’s team. In July 2023, Emery Oleochemicals announced that its Cincinnati plant had achieved RSPO Mass Balance (MB) Supply Chain Certification.
