Is PEG-45 Palm Kernel Glycerides natural?

Mostly not. The palm-kernel glyceride core is natural, but forty-five ethylene oxide units make up most of the mass.

How we scored it

Palm-kernel mono/diglycerides ~370 Da (natural, lauric-rich) ethoxylated with 45 mol ethylene oxide (45 x 44.05 = 1982 Da, petrochemical); the INCI number fixes the EO count. 370/2352 = 0.16.
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

Palm kernel oil glycerides ethoxylated with petrochemical ethylene oxide.

In plain English

An emulsifier made from palm kernel oil glycerides combined with ethylene oxide, a petroleum-based building block. Helps blend water and oil in a formula.

CosIng definition: Mono- and diglycerides, palm kernel oil, ethoxylated (12 mol EO average molar ratio)
