Transesterification of Castor Oil with Trimethylchlorosilane: Simultaneous Formation of Fatty Acid Alkyl Esters and α-Monochlorohydrin

Researchers performed an experiment where transesterification of castor oil was done using trimethylchlorosilane as acidic mediator. Two one-pot reactions were observed. castor oilOne was the transesterification of triglycerides relevant to biodiesel production and the other was the chlorination of glycerol with the formation of α-monochlorohydrin.

Results showed that the two products biodiesel and α-monochlorohydrin were obtained in high quantities and that the synthesis represents a highly sustainable production of industrial commodities from available biomass.

Antimicrobial Action of Sodium Hypochlorite and Castor Oil Solutions for Denture Cleaning – In Vitro Evaluation

Researchers from Brazil conducted an experiment to evaluate the antimicrobial actions of sodium hypochlorite and castor oil solutions against specific microorganisms. Acrylic castor oilresin specimens were obtained, sterilized and contaminated with important bacterial and Candida species.

Results showed that sodium hypochlorite solutions completely eliminated all microorganisms while castor oil solution provided moderate efficacy and performed differently on tested species.


Wound Healing Bionanocomposites Based on Castor Oil Polymeric Films Reinforced with Chitosan-Modified ZnO Nanoparticles

Researchers from Spain used castor oil as a matrix material to prepare biocompatible and biodegradable nanocomposite films filled with chitosan modified ZnO nanoparticles for wound healing. The biocomposites were prepared by solution mixing and casting method. The morphology, structure and wound healing properties of Castor oilthe films were analysed. The antibacterial activity of the films were investigated in the presence and absence of UV light.

Results showed that the antibacterial activity was stronger against gram positive bacteria. Composites with nanoparticle loading enabled faster wound healing thus showing the potential to be applied as antibacterial wound dressings.
