Is Dimethyl Oxazolidine natural?

No. Both the formaldehyde and the amino-alcohol precursor are petrochemical; the oxazolidine ring is a synthetic formaldehyde-releasing preservative.

How we scored it

Ring formed from formaldehyde (methanol-derived, n=0) + 2-amino-2-methylpropanol (synthetic nitroparaffin-route amino alcohol, n=0) → 0/101 = 0.0
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

Synthesised by reacting formaldehyde with 2-amino-2-methyl-1-propanol, both petrochemical intermediates, to form the oxazolidine ring. No natural-origin route is used commercially.

In plain English

A lab-made preservative that slowly releases small amounts of formaldehyde to keep microbes from growing in a product. It is synthesised from formaldehyde and a synthetic amino alcohol, not from plants.
