New liquid biodiesel stabilizer with optimized performance
Albemarle, a market leader in cost-efficient biodiesel stabilization solutions, is proud to announce the release ofETHANOX® 4760E, the latest in its range of biodiesel stabilizers. Biodiesel can come from many different sources, for example, soybean oil, animal fat, palm oil, rapeseed oil and yellow grease.Biodiesel derived from yellow grease is made from an abundant and underutilized resource, used cooking oil from restaurants, the cheapest feedstock thus far targeted for bio-based fuel production. Themanufacturing process for biodiesel removes natural antioxidants and leaves the fuel unprotected from oxidative degradation. This causes a build-up of gums and acids in the engine that causes poorcombustion, fuel-filter plugging and other problems such as deposits on injectors and pistons. ETHANOX antioxidants have the ability to trap the free radicals that lead to the development of gums and,therefore, considerably reduce the level of oxidations.

Albemarle previously introduced ETHANOX 4740, a liquid blend of antioxidants with strong synergies that provides a cost-effective solution for less stable biodiesel. Now,Albemarle has continued its pioneering development of innovative biodiesel stabilizing technologies with the introduction of ETHANOX 4760E. Like ETHANOX 4740, this latest stabilizer has the sameeasy-to-handle liquid form, but with highly improved cost-efficiency and performance for several feedstocks.
