Is Dipropylene Glycol Salicylate natural?

No. Dipropylene glycol is made from propylene oxide and salicylic acid from phenol, so neither fragment is natural origin.

How we scored it

Salicyloyl C7H5O2 121.1 (phenol) 0; dipropylene glycol-O part C6H13O3 133.2 (propylene oxide) 0; total C13H18O5 254.3; 0/254.3 = 0.00.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Dominant route: esterification of petrochemical salicylic acid with dipropylene glycol, a by-product of propylene glycol manufacture from propylene oxide. Bio-based propylene glycol exists, but the site rules treat propylene glycol as petrochemical.

In plain English

An ester of dipropylene glycol and salicylic acid, used to soften skin and adjust a formula's thickness. Both parts are made from petrochemicals: the glycol from propylene oxide and salicylic acid from phenol.
