Biosynthetic® Base Oils


Biosynthetic® base oils are based on Estolides, a new class of bio-based compounds with excellent properties for several different lubricant applications.

Estolides are naturally derived, biodegradable, nontoxic, and nonbioaccumulative. In addition to an improved environmental profile, these materials impart excellent performance characteristics in lubricants, including improved lubricity, higher flash points, and hydrolytic stability, improved cold temperature properties, and excellent load-carrying capacity.

Biosynthetic® base oils come in several different viscosity grades for various applications (i.e., BT4, BT22, BT22LD, BT75) including food-safe lubricants, industrial lubricants, passenger car motor oil, marine lubricants, and metalworking fluids. 

These products range in bio-content from 65 – 95% per ASTM D6866 and can be used as primary lubricants or blended with other ingredients for specific use cases.

Biosynthetic® Technologies’ primary product line, sold under the name of Biosynthetic Base Oil, is comprised of biobased oils that are synthesized specifically for high performance lubricant applications in the automotive and industrial sectors.

Example Estolide Lubricant Applications from Biosynthetic Technologies:

  • Passenger car motor oil (PCMO)
  • Marine lubricants
  • Small engine oil (2T/4T)
  • Hydraulic fluid
  • Wind Turbine Refrigeration/compressor oil
  • Food-grade lubricant
  • Grease Dielectric (transformer) fluid
  • Metalworking fluid
  • Gear oil
  • Bar and chain oil
  • General purpose lubricant
  • Plastics
