Is Trideceth-7 natural?

No. Isotridecanol and its ethoxylate chain are both petrochemical, so the formula/description mismatch does not affect the outcome.

How we scored it

Isotridecanol (petrochemical branched C13 alcohol) + 7xEO (petrochemical) — entirely petrochemical regardless of chain length; 0/total = 0.0. Supplied formula (C15H32O2) matches ~1 EO, not the stated 7, but doesn't change the result.
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

Isotridecyl alcohol is manufactured by oxo-synthesis of propylene tetramer, then ethoxylated with petrochemical ethylene oxide. No natural feedstock is used.

In plain English

A branched synthetic alcohol made from petrochemical propylene, reacted with ethylene oxide, also petrochemical. Used as a cleansing emulsifier that blends oil and water in cleansers and lotions.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-tridecyl-.omega.-hydroxy- (7 mol EO average molar ratio); Isotridecanol, ethoxylated
