Material efficiency is nowadays an essential topic to promote the sustainable use of natural resources, waste materials and industrial by-products, in agreement with the principle of sustainable development and LCA (life cycle assessment). In this research it was determined the biodegradation of used vegetable oil based products and their important physicochemical properties for their suitabili...
متن کاملOzonized vegetable oils and therapeutic properties: A review
Ozonized oils represent an interesting pharmaceutical approach to the management of a variety of dermatological pathologies. Ozone reacts with carbon-carbon double bonds of unsaturated fatty acids according to the mechanism described by Criegee, forming ozonides or 1,2,4 trioxolane rings and peroxides as the most important products, responsible for the antimicrobial activity and stimulating tis...
متن کاملOn the Use of Dielectric Spectroscopy for Quality Control of Vegetable Oils
− Quality control of vegetable oils is becoming more stringent, and related laws are being enforced, especially for avoiding adulteration. As a result, there is a substantial need for methods of analysis that could provide real-time in-situ monitoring, especially for quality control purposes during production process. In this regard, the present paper investigates the possibility of monitoring ...
متن کاملLubricant basestocks from vegetable oils
Oil Chemical Research. USDA l-ARS-NCAUR. 1815 N. U;liuersity Street, Peoria, IL 61604, USA Accepted 8 October 1999 Compared to the lubricants made of petroleum, vegetable-based lubricants are much more biodegradable but inferior in many other technical characteristics. The basestock typically contributes to more than 80% of lubricant and must meet performance criteria in such aspects as cleanli...
