Is Stearamidopropyl Dimethylamine Lactate natural?

Mostly. Stearoyl comes from palm or tallow stearic acid and lactate from sugar fermentation; the dimethylaminopropyl amine (DMAPA, from acrylonitrile and dimethylamine) is petrochemical.

How we scored it

Stearoyl C18H35O 267.5 + lactic acid 90.1 = 357.6 natural; DMAPA residue C5H13N2 101.2 petrochemical. 357.6 / 458.7 = 0.78.
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

Stearic acid is condensed with petrochemical DMAPA to give the amidoamine, which is neutralised with fermentation lactic acid. Petrochemical stearic-range chains or synthetic lactic acid are uncommon alternatives.

In plain English

A conditioning agent that becomes positively charged in acidic products, so it sticks to hair and reduces static. It is an amide of stearic acid (from palm or tallow) neutralised with lactic acid from fermentation.
