Is DEA-Methoxycinnamate natural?

No. The methoxycinnamate chromophore is built from petrochemical aromatics and methanol, and diethanolamine comes from ethylene oxide and ammonia.

How we scored it

C14H21NO5 283.3 Da: 4-methoxycinnamic acid (anisaldehyde plus malonic or acetic reagents) 0; diethanolamine (ethylene oxide, ammonia) 0; 0 / 283.3 = 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

Anisaldehyde is condensed with malonic acid or acetic anhydride to give 4-methoxycinnamic acid, which is neutralised with diethanolamine. Anethole-derived anisaldehyde exists but is a minor source.

In plain English

A UV-absorbing sunscreen ingredient, supplied as a salt of 4-methoxycinnamic acid and diethanolamine. Both parts are made industrially from petrochemical raw materials.
