Biosynthetic Technologies Castor Derivatives
BioEstolide Certification Logos

Biosynthetic Technologies manufactures a revolutionary new class of biobased synthetic compounds called Estolides that are made from organic fatty acids found in various bio-derived oils. These highly functional biosynthetic oils have numerous uses in lubricant, automotive, marine, and personal care applications and can be used as the primary base oil of a lubricant formulation, a component of a base oil co-blend, or even as an additive. In addition, Biosynthetic Technologies offers a line of castor derived products used in the formulation of metalworks fluids and Food Grade Lubricants.

At Biosynthetic® Technologies, we understand the importance of sustainable manufacturing practices. We are constantly looking for ways to minimize the negative impacts on the environment while conserving energy and natural resources. Our objective is to make sustainability a point of difference for our business, and we are confident that this strategy will generate even greater benefits for the environment in which we operate, the people that we work with and the communities we are part of. Biosynthetic Technologies is committed to sustainability and clearly focused on the responsible use of natural resources in our daily business. We understand that health, environmental awareness and traceability play just as large a role for consumers as quality and efficacy.

Ricinoleic Acid

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.

Castor Derivatives Applications

  • 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.
