I just looked this up, and it appears to just be a plant based lipid product. It has been recognized by the FDA as safe (sorry, I didn't find the EFSA version, but I did find an application to the FSANZ referencing that the EFSA had concluded them to be safe ...)
Basically, it's derived from grapeseed oil, it's been scientifically shown to be safe, it's a component in metabolic processes, and you're already eating these things anyways.
FDA GRAS Approval
"The constituents of a mixture of monoacylglycerides derived from grape seed are found in nature. As per 21 CFR 184.1505, mono- and diglycerides that consist of a mixture of glyceryl mono- and diesters and minor amounts of triesters are affirmed as GRAS for direct addition to food. The mono- and diglycerides are permitted for use in food with no limitation other than current Good Manufacturing Practice. These esters can be used in food for multiple purposes, for example, as: a dough strengthener; an emulsifier and emulsifier salt; a flavoring agent and adjuvant; a formulation aid; a lubricant and release agent; a solvent and vehicle; a stabilizer and thickener; a surface-active agent; a surface-finishing agent; and a texturizer.
The constituents of the mixture of monoacylglycerides derived from grape seed are present in the diet as components of conventional dietary oils and as approved food additives (i.e., mono-and diglycerides), and are formed from normal lipid metabolism following the consumption of dietary fat. There is no evidence that the presence of monoglycerides or diglycerides of food fats have any deleterious effect on cells or tissues."
FSANZ Application
"Mono- and diglycerides have an extensive history of safe use in a variety of foods and are allowed for use as a glazing agent on fresh fruits and vegetables in several countries and regions, including Canada, Chile, China, Colombia, Japan, Mexico, Peru, and the United States, and are allowed on certain fruits in the European Union. JECFA established an acceptable daily intake (ADI) of “not limited” in 1974,2 and an EFSA Panel concluded in its 2017 re-evaluation of mono- and diglycerides that there was no safety concern for the reported uses and use levels."
