This is a Natural Esther	This is a Synthetic Ester

Inolex knows Esters, and so should you.  We have provided the chemical refresher above for those new to the metalworking fluid industry.  A more detailed treatment can be found in a whitepaper from INOLEX. 

Market Watch reports that eight Inolex Lexolube synthetic esters, used to produce lubricants used for food processing, textile manufacturing, metalworking fluids, hydraulic fluids, chain lubricants and low temperature oils and greases, were recently approved for use in food processing applications by the Canadian Food Inspection Agency (CFIA).  We only care about the ones provided as additives for metalworking fluids, so a complete product list for Inolex is provided here [MWF ADDITIVES].
