Dipropylene Glycol and Propylene glycol - natural origin
Hi, I am looking for Dipropylene Glycol and Propylene glycol, but not from petrochemical origen. Do you know if it is available from a renewable source, either botanical or biotechnological? So far I could not find this alternative for those one. Thanks!

Zemea (Propanediol) is plant-based and often used in place of PG.

You’ll have a hard time finding dipropylene glycol because it’s an ether and ethers are quite rare in nature.Propylene glycol can be prepared (synthetically using green chemistry) from renewable feedstock such as lactic acid but to my knowledge isn’t (yet) done on a commercial scale probably because production of propanediol (above mentioned Zemea) is more economical and ‘chemistry-free’.
