Is Hydrogenated Polydecene natural?

No. 1-Decene is an ethylene-derived petrochemical alpha-olefin; polymerising and hydrogenating it adds no natural mass.

How we scored it

Homopolymer of 1-decene (petrochemical alpha-olefin from ethylene oligomerisation), then hydrogenated; no natural fragment.
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

Made by polymerising 1-decene, itself derived from petrochemical ethylene oligomerisation, then hydrogenating the polymer. Bio-based decene exists but is not the dominant commercial route.

In plain English

A lightweight emollient oil made by polymerising and hydrogenating decene, a synthetic hydrocarbon. It conditions skin and hair and helps other ingredients spread smoothly.

CosIng definition: 1-Decene, homopolymer, hydrogenated
