Is C14-15 Pareth-13 natural?

No. An ethoxylate of a synthetic odd-and-even-carbon alcohol blend; both the alcohol and the ethylene-oxide chain come from petrochemicals.

How we scored it

C14-15 Pareth-13: the C14-15 alcohol blend is made by oxo or Ziegler synthesis from petrochemical olefins, and the 13 ethylene-oxide units are petrochemical → 0.00. Same treatment as the site's C12-15 and C12-13 pareths.
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

Oxo-process C14-15 alcohols ethoxylated with about 13 mol of ethylene oxide.

In plain English

A cleansing and emulsifying ingredient made from a fatty alcohol reacted with ethylene oxide. The fatty-alcohol part may come from coconut or palm oil, or from a synthetic petroleum-based alcohol; the rest is petrochemical.

CosIng definition: Alcohols, C14-15, ethoxylated (13 mol EO average molar ratio)
