Is Laureth-16 natural?

Mostly not. Lauryl chain from coconut/palm-kernel oil (natural); the 16-unit polyoxyethylene chain from petrochemical ethylene oxide.

How we scored it

Lauryl alcohol C12H26O (natural/oleochemical, 186 Da) + 16 EO (petrochemical, C2H4O x16 = 705 Da) = 186/891 = 0.21.
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 commercial route ethoxylates coconut- or palm-kernel-derived lauryl alcohol with petrochemical ethylene oxide. A minority of lauryl alcohol supply is synthetic (Ziegler/oxo process); if that source were used, NOI would fall to 0.0.

In plain English

A mild cleansing and emulsifying surfactant made by reacting coconut- or palm-derived lauryl alcohol with ethylene oxide, a petrochemical. Helps products foam and helps water and oil mix.
