Biosynthetic® Technologies manufactures a revolutionary new class of biobased synthetic compounds called Estolides. These are naturally derived oils that improve the quality of formulated products and are biodegradable. Estolides are a class of unique bio-based oils with a variety of uses. Their oligomeric structure contains fatty acid repeat units, with secondary ester linkages on the alkyl backbone. The chemical structure is shown here.

Functional groups denoted as α and β, oligomer length n, and the fatty acid feedstock can all be manipulated in order to achieve desirable performance properties.

Relevant technical performance properties include increasing or decreasing viscosity and polarity, as well as improving cold temperature properties and oxidative and hydrolytic stability.

Our sustainable and renewable base oils exhibit excellent lubricity and load carrying characteristics, strong oxidative stability, and good demulsibility. In addition, they show high flash point, with closed-cup values ranging from 200°C to 245 °C (ASTM D93) and open-cup values ranging from 240°C to >260 °C (ASTM D92).

Biosynthetic Technologies’ base oils display good cold temperature performance as well, with pour points ranging from -18 °C to -42 °C (ASTM D97).

In addition to their impressive technical performance, Estolides offer excellent environmental performance. These oils contain high bio-content, are biodegradable and nontoxic, and do not bioaccumulate.

At Biosynthetic Technologies, our base oil products are 70-90% biodegradable (OECD 301) with a bio-content (ASTM D6866)  of 65-95%. Additionally, they displayed no bioaccumulation (OECD 107) and were non-toxic at 1000 mg/mL (OECD 201, OECD 202, OECD 203, OECD 209).
