Novel One Shot Method for Synthesis of Castor Oil Polyurethane Foam

Researchers from India prepared castor oil polyurethane from pre-polymer oftoluene diisocyanate (TDI) and castor oil with dibutyl tin dilaurate (DBTDL) catalyst. Homepagecarroussel-research1Water was used as blowing agent. The rate of forming was increased by increasing catalyst and water content. On other hand the cell size of the PU decreased with increasing amount of the catalyst and water content.

Characterization studies were performed to analyse the properties of synthesized foam.

New Castor Oil Based Polyurethanes Reinforced With Double-Decker Silsesquioxane

Scientists from China synthesized hybrid polyurethanes with double-decker silsesquioxane (DDSQ) using castor oil and isophorone diisocyanate (IPDI) as feedstock. Double-decker octaphenyl silsesquioxanetetraol (DDSQ) was prepared and characterized castor oil polyurethaneby spectroscopy.

Results showed that with the inclusion of DDSQ, the hydrophobicity of the hybrid material was significantly improved.

Bioplastics Market & Strategy Consulting – from Bioplastics Guide

EAI, the parent company of CastorOil.in, had been studying the bioplastics industry for the past few years and in the recent past we had the opportunity to look at the sector, in India and worldwide at close quarters.

Based on these, we have put together an exclusive team to provide strategic and market consulting for the global bioplastics industry.

If you are interested in the bioplastics sector and the opportunities it presents, see here to know how the Bioplastics Guide can help you get a strategic understanding of the bioplastics market.

Bioplastics Applications & Uses – Current, Emerging Markets – Bioplastics Guide

The Bioplastics Guide, an initiative by EAI, is a focussed consulting and market research division for the global bioplastics and biopolymers sectors.

The Guide has an interesting section that provides an overview of the end use segments and applications for bioplastics.

Get to know more about the current and emerging end use segments for bioplastics from this page @ the Bioplastics Guide.

New Castor Oil Based Green Plasticizer

Scientists from India performed esterification of furfuryl alcohol and castor oil fatty acid at 3:1 molar ratio, by immobilized Candida antarctica Lipase B in a solvent free system.castor-oil-800067 A maximum yield of ester was obtained. Performance of the FA-COFA ester plasticized Ethyl Cellulose (EC) films were evaluated by certain characteristic studies.

Results showed that the furfuryl alcohol-castor oil fatty acid ester with significant plasticizing property at a certain concentration could act as a substitute for traditional plasticizer dibutyl phthalate.

Castor Oil Biodiesel–Diesel Blends for Compression Ignition Engine

Researchers performed an experiment where castor oil, ethyl ester were prepared by castor-oil-800067transesterification using potassium hydroxide (KOH) as a catalyst and tested on a four-stroke, single-cylinder compression ignition engine. The test was carried out at a constant speed of 3000 rpm at different loads.

The results represent a substantial decrease in carbon monoxide (CO) emission with an increasing biodiesel percentage.

Castor Oil Based Drug Delivery Systems

Levosulpiride (LSP) is a hydrophobic benzamide derivative used in the treatment of schizophrenia. In order to enhance the drug absorption and bioavailability, castor-oil-800067scientists from India did a research to formulate castor oil based globule.

Results showed that at a certain ratio of castor oil, polyethylene glycol and Tween 20, the formulation had shown uniform globule size, no interactions of LSP with Self Nano Emulsifying Drug Delivery System components and a higher pharmacokinetic parameter than that of commercial preparation.

Ricinoleic Acid Based Electrospun Fibres

Ricinoleic acid, derived from castor oil has an anti-inflammatory action following topical application. However ricinoleic acid goes rancid when it is exposed to oxygen.  ricinoleic-acid-61245Hence scientists from Egypt performed an experiment to encapsulate ricinoleic acid into ethyl cellulose (EC) electrospun fibres.  Electrospinning parameters of EC were optimized to obtain bead-free fibres.

RA at different concentrations was encapsulated into EC fibres. Release profile was reported and encapsulation was demonstrated via morphological analysis.

New Catalyst for Biodiesel Production from Castor Oil

Scientists from Brazil performed an experiment to optimize and investigate the biodiesel production from castor oil using microwave-assisted hybrid transesterfication process under various conditions such as microwave power, treatment time, ethanol:oil ratio and catalyst concentration (KOH).

Results showed that under optimal conditions the predicted biodiesel production was found to be 95% with a desirability value of 0.998.

New Castor Oil/PCL Based Bio-PU Foam

Scientists from Korea performed an experiment to fabricate castor oil/PCL based bio-polyurethane foam reinforced with nano cellulose. PU foam based on biomaterials castor oil polyurethanewas investigated to replace traditional petroleum-based polyol. Polyols were synthesized from castor oil (CO) and polycaprolactone (PCL). In addition, the effects of the nanocellulose on the thermal and mechanical properties of CO-based PU foam were investigated.

Results showed that addition of the nanocellulose could be an effective way to improve the mechanical and thermal properties of PU foams.
