Glycerine acetate is a mixture of esters produced from the esterification of glycerol (1) with acetic acid. This reaction produces five congeners:
- the two monoacetylglycerols / MAG / monoacetin (2 and 3)
- the two diacetylglycerols / DAG / diacetin / glyceryl diacetate (4 and 5)
- the one triacetalglycerol / TAG / triacetin (6)

DAG and TAG can be used as fuel additives for improving the cold and viscosity properties of biodiesel or the antiknocking properties of gasoline.[1]
