"The need for innovation in lubrication continues as the manufacturing sector experiences the transformation termed “Industry 4.0,” or the Fourth Industrial Revolution. Advances in robotics, human machine interaction, advanced analytics, additive manufacturing such as 3-D printing, and artificial intelligence are creating demand for new and novel lubricants. Furthermore, there continues to be a significant focus on choosing lubricants that are safer to use and aligned with ever tighter environmental regulations. For example, there is a growing demand for lubricants that are designed from oleochemical versus petrochemical feedstocks. "

"The unique chemistry of SPE base oils provides some additional performance functionalities that conventional synthetic esters may not offer, all while providing excellent environmental performance. These oxygen-rich structures—with in-built detergency, good hydrolytic stability and oxidation stability—provide formulators with a new sustainable base oil choice. This new patented platform chemistry—with a vast number of options for designing new base oils or additives—offers a promising solution to solving some of today’s most pressing lubrication and formulation challenges."

Notice what isn't said: how they react to zddp and other anti-wear components.

I love what esters can do in a formulated oil, but too much polarity is a risk....
