India, the market leader in production and supply of castor seed and castor oil may soon capture a major share in castor derivatives market with companies like Adani Wilmar and Royal Castor Products engaging in second- and third-generation castor seed and castor oil derivatives production and exports.
According to industry experts, high technology cost has been the major reason for India in not capturing a large share of the global derivatives market. In the derivatives segment, there is a huge potential for India and focusing more on marketing also could help India shine in castor derivatives market.
Recent market study has shown that revenue from castor oil and derivatives market could increase in the near future. Sebacic acid and dehydrated castor oil are among the major revenue generators in the global castor oil market. Large-scale adoption of sebacic acid in plasticizers, lubricants, cosmetics is catalysing its growth in the global market.
In the end user application areas, cosmetics, pharmaceuticals, surface coatings, plastics and resin industry are the largest consumers of castor oil whereas the surface coatings industry is the fastest growing end-user for the castor oil.
Asia Pacific is the largest consumer of castor oil and is expected to retain the higher growth rate during the next few years due to strong growth in surface coatings, pharmaceuticals, and cosmetics industry.
The global castor oil and derivatives market is expected to reach USD 2.30 billion by 2024. The market is estimated to witness a high growth owing to increase in demand for biodegradable products and increasing trend to reduce dependence on petrochemicals are expected to foster the market growth.
Asia Pacific dominated the overall market. Growth in end-use markets such as personal care, lubricants, and pharmaceuticals is presumed to fuel the regional demand over the next eight years.
Researchers performed an experiment to synthesize castor oil based biothiols with good stability for use in photoinitiator free UV coatings. Castor oil based biothiols were synthesized via esterification reaction between castor oil (CO) and 3-mercaptopropionic acid (MPA).
Characterization studies showed that the targeted oligomer was successfully prepared. Finally, the UV-curable films of CO-SH also showed good physical and chemical properties.
Sebacic acid size was estimated over 100 kilo tons in 2014 and is likely to exceed 130 kilo tons by 2023. Polyamide application witnessed the highest sebacic acid market consumption in 2014 and is likely to gain steady rates over the forecast period.
Shift in trend towards manufacturing biobased polymers from renewable sources is a key driver for the growth of sebacic acid market. Sebacic acid is used in wide applications such as cosmetics, plasticizers, biopolyamides production etc.

Recent research shows production of jet fuel from ricinoleic acid methyl ester.
Experiments conducted earlier have shown the possibility of producing jet fuel from castor oil or hydro processing castor oil.
Now scientists from China have found that jet fuel could be produced from castor oil derived ricinoleic acid methyl ester. A unique hydroxyl group in the ricinoleic acid chain induced a special thermal rearrangement reaction in medium chain fatty acid methyl ester (FAME) and heptanal formation. This reaction was used as a starting point for the production of jet fuel.
Results showed that the carbon selectivity in the castor oil to jet fuel process was as high as 90%.
Polyanhydrides are a class of biodegradable polymers that are usually unstable and prone to hydrolytic degradation and depolymerisation. They need to be stored at -20°C, packed under inert atmosphere until use.
Now researchers from Israel have found a new stable polyanhydride obtained from sebacic acid and ricinoleic acid. The new stable polyanhydride was synthesized with alternating ester anhydride structure that is stable at 25 °C for over 18 months. The copolymer is also stable in chloroform solution and under γ-irradiation.
Here’s an interesting derivative possibility of an antibacterial product from ricinoleic acid, a derivative of castor oil.
Contamination is a big issue in any environment. It affects each and every stage in all the processes we do from manufacturing a product to its maintenance (shelf life). To control contamination, a suitable compound with a high antibacterial activity is to be added in an ongoing process.
A well-known example of compounds with antibacterial activity are naturally occurring phenolic compounds.
Now scientists from India have developed 7 novel ricinoleic acid glycosides having antibacterial activity using Koenigs–Knorr glycosylation reaction. On the whole, 28 ricinoleic acid glycosides were developed and their antibacterial activities were analysed. Seven of them were found to show promising wide spectrum antibacterial activity against gram positive bacteria.
Among the 7 compounds, two compounds namely mannopyranosyl- and the arabinofuranosyl derivatives were found to be effective against various non-clinical/clinical, overexpressed/resistant strains of Staphylococcus aureus and other gram positive bacteria such as Bacillus subtilis and Micrococcus luteus. It was found that the presence of sugar and its structure and the methyl ester protection of the carboxylic moiety of ricinoleic acid are responsible for these compounds to be bioactive.
Now industries looking for other potential compounds with antibacterial activity could go for these ricinoleic acid glycosides.

Here is an interesting article on the enhanced neuroprotective effects of undecylenic acid.
Undecylenic acid, a synthetic unsaturated fatty acid obtained from castor oil is a well-known potent antifungal agent. In 2012, scientists from Korea found that undecylenic acid has the ability to inhibit µ-Calpain activity, a factor responsible for neurological disorders like Alzheimer’s disease. This showed the neuroprotective effects of undecylenic acid.
Now scientists from Poland have done an experiment to improve the efficiency of neuroprotective effects of undecylenic acid by targeting it using polyelectrolyte coated nanocapsules. Core shell nanocapsules were prepared using nanoemulsification and the layer by layer technique. The average size of nanocapsules was around 80nm and the concentration was 2.5×1010 particles/ml. The nanocapsules were coated with either polycation or polyanion layers.
Biocompatibility of the synthesized nanocarriers was evaluated in SH-SY5Y human neuroblastoma cell line using cell viability/toxicity assays.
Results showed that nanocapsules coated with PLL and PGA were non-toxic to the human neuroblastoma cell line, thereby showing its potential to be used as a carrier of undecylenic acid. Further research showed that nanoencapsulated form of undecylenic acid was biocompatible and more effective against staurosporine-induced damage in lower concentrations than those of the same drug added directly to the culture medium.
This shows that undecylenic acid could be more effective in nanoencapsulated form against neurological disorders.
