Many end users and lubricant marketers face a conundrum regarding how to select and apply H1 and H2 food plant lubricants. As explained in the July issue of Lubes’n’Greases, H2 is not food grade, and those with any level of experience providing lubricants for food and beverage processors know the difference.
Having marketed into the food industry long enough to grasp the intent and meaning of the two categories, I believe both are vital and necessary. But some key information was missing from that July article. Start by noting that the issues cover used incorrect wording, possibly misleading the casual observer into believing that H1 and H2 lubricants are both food grade. H2 is not food grade.
