Is DEA-Lauryl Sulfate natural?

Mostly. Lauryl sulfate is oleochemical (coconut/palm-kernel); the diethanolamine counter-ion is a synthetic amine made from petrochemical ethylene oxide and ammonia.

How we scored it

Dodecyl hydrogen sulfate 266 Da (natural) + diethanolamine C4H11NO2 105 Da (petrochemical amine) -> 266/371 = 0.72.
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

Lauryl alcohol from coconut or palm kernel oil is sulfated, then neutralised with diethanolamine, an amine manufactured from petrochemical ethylene oxide and ammonia. The fatty portion dominates the molecule's mass.

In plain English

A cleansing agent made from coconut or palm-kernel fatty alcohol, neutralised with a small synthetic amine. Used in shampoos and body washes to create foam and remove oil.
