Biodegradable Lubricant from Castor Biodiesel Esters

Worldwide, 12 million tonnes per year of lubricants are disposed of in the environment through leakages, exhausted gas, incorrect disposal, water–oil emulsions and so on. Some are resistant to biodegradation, representing an environmental threat. One solution to modify this situation is the replacement of mineral oils by biodegradable synthetic lubricants. Esters, whose chemical structures are similar to natural triglycerides, are excellent substitutes for mineral oils. Castor oil contains around 90% ricinoleic acid, and as a result, castor oil has a higher viscosity and a lower viscosity index, compared with other vegetable oils. This work was based on the production of biodegradable lubricant base fluids from castor biodiesel esters, using various chemical catalysts.

Castor oil During Term Pregnancy

Derived from the castor plant Ricinus communis, castor oil may possess properties that are useful in post-term pregnancies Research studies reveal that castor oil was considered successful if labor began within 24 hours after dosing. Women who receive castor oil have an increased likelihood of initiation of labor within 24 hours compared to women who receive no treatment. Castor oil use in pregnancy is underreported worldwide. Read More: http://www.ncbi.nlm.nih.gov/pubmed/10631825
