Is Sodium Methyl Lauroyl Taurate natural?

Mostly. Lauric acid supplies the natural acyl group; the N-methyltaurine portion is built from petrochemical ethylene oxide and methylamine.

How we scored it

Lauroyl (dodecanoyl) C12H23O natural fatty fragment = 183.3 Da; N-methyltaurate-Na remainder from ethylene-oxide/methylamine chemistry, petrochemical = 160.2 Da → 183.3/343.5 = 0.53.
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 condensing lauric acid (coconut/palm-derived) with sodium N-methyltaurate, itself synthesized from ethylene-oxide/isethionic-acid chemistry and methylamine. The fatty acid and taurate fragments are roughly equal in mass.

In plain English

A mild cleansing surfactant made from lauric acid, sourced from coconut or palm oil, combined with a taurine derivative. Roughly half the ingredient is natural fatty acid and half is synthetic.
