Biosynthetic Technologies  manufactures a wide range of products ranging from Castor Derivatives to Sustainable Base Oils for a variety of applications.

Biosynthetic Technologies has developed and patented a new class of compounds called estolides to meet the sustainability challenge for many applications. Our estolide technology has been used to develop a product line of sustainable high performance base oils that can be used in a variety of application ranging from industrial lubricants to personal care products.

Our sustainable base oils are especially suitable for the following applications: Food Grade Lubricants, Marine Lubricants, PCMO, and Metalworking Fluids. Our product range covers 4 sustainable base oils with ISO VG ranging from 22 – 680.

These sustainable base oils are made from naturally derived oils and improve the quality of formulated products and enhance their biodegradability. 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 above.

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.

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.

With a highly customizable structure, estolides’ physical properties can be manipulated for specific applications. In addition, their environmental compatibility allows them to be used in widespread industries ranging from lubricants to personal care. Overall, estolides serve as naturally derived oils that improve the quality of formulated products.

Research shows that these high performance sustainable base oils deliver high biodegradability, are non-bioaccumulative and are non-toxic. Their high bio content delivers excellent hydrolytic stability and oxidative stability with low volatility. The benefits of first-rate lubricity combined with superb wear protection and a high viscosity index deliver the performance characteristics sought after for quality finished lubricants. In addition, estolides provide remarkable seal compatibility as well as natural detergency.

Castor Derivatives

Biosynthetic Technologies manufactures a wide range of castor oil derivatives. These castor oil derivatives comply with highest standards of quality in the market today. Castor Oil is a biodegradable and renewable resource for a large range of raw materials. Castor oil and its derivatives are used in a wide array of applications ranging from heavy duty hydraulic fluids, to cosmetics and pharmaceutical applications. Biosynthetic Technologies offers a comprehensive castor oil derivatives that carry sales approval for US (EPA), Canada (CEPA), and Europe (REACH). Our product line is comprised of the following castor derivatives:

RA Homopolymer – AV 100

RA Homopolymer – AV 50

Di-Ethylhexyl Sebacate

Di-Sodium Sebacate

Ricinoleic acid is an unsaturated omega-9 fatty acid and a hydroxy acid. It is a major component of the seed oil obtained from mature Castor plant. Ricinoleic Acid can be used as a thickener for silicon grease, as a rubber activator/accelerator and in the manufacture of certain personal care products, among other applications. This product can be used as a sustainable alternative to other emollients and thickeners. 12-hydroxy stearic acid is entirely vegetable-based, and not tested on animals at any part of the manufacturing process. Its GMO-free, and contains no peanuts, tree nuts, wheat, grains, dairy, eggs, fish or gluten. It also contains no residual solvents and is REACH registered for use in the European Union. 12-hydroxystearic acid is nonreactive, nonflammable and not an explosive hazard.  The hydroxyl functionality of RA makes the castor oil a natural polyol providing oxidative stability to the oil, and a relatively high shelf life compared to other oils by preventing peroxide formation. The presence of the hydroxyl group in RA and RA derivatives provides a functional group location for performing a variety of chemical reactions including halogenation, dehydration, alkoxylation, and esterification. As a result, this unique functionality allows the castor oil to be used in industrial applications such as paints, coatings, inks, and lubricants.

Biosynthetic Technologies Castor Derivatives

Applications of Castor Oil and its Derivatives

  • Polymer materials – Castor oil and its derivatives can be used in the synthesis of renewable monomers and polymers. Biodegradable polyesters are one of the most common applications using castor oil. They are known to be biodegradable and environmental friendly, with a wide array of applications in the biomedical field, as well in the preparation of elastomers and packaging materials.
  • Soaps, waxes, and greases – Castor oil has been used to produce soaps in some studies. Some studies also utilize castor oil in waxes. One study by Dwivedi and Sapre utilized castor oil in total vegetable oil greases. Total vegetable oil greases are those in which both the lubricant and gellant are formed from vegetable oil. Their study utilized a simultaneous reaction scheme to form sodium and lithium greases using castor oil.
  • Lubricants, hydraulic, and brake fluids – Castor oil has also been used for developing low pour point lubricant base stocks through the synthesis of acyloxy castor polyol esters. The low pour point property helps to provide full lubrication when the equipment is started and is easier to handle in cold weather. An interesting study showed the excellent potential of castor oil-based lubricant as a smoke pollution reducer. In this research, a biodegradable two-stroke (2T) oil, a popular variety of lubricating oil used on two-stroke engines in scooters and motorcycles, was developed from castor oil, which consisted of tolyl monoesters and performance additives, but no miscibility solvent. Their performance evaluations showed that it reduced smoke by 50%–70% at a 1% oil–fuel ratio, and it was on par with standard product specification. In addition to the possible use as a car engine lubricant, a modified version of castor oil lubricant comprising 100 parts of castor oil and 20–110 parts of a chemically and thermally stable, low viscosity blending fluid, soluble in castor oil showed its potential as a lubricant for refrigerator systems.
  • Coatings – Coatings and paints are also another application of castor oil.
