Is Sucrose Tetrastearate Triacetate natural?

Mostly. Sucrose (sugar beet or cane) and stearic acid (vegetable oil) are natural, while the three acetyl caps come from petrochemical acetic anhydride.

How we scored it

C90H164O18, 1534.3 Da: 3 acetyl C2H3O 43.0 = 129.1 petrochemical (acetic anhydride); sucrose core 335.2 + 4 stearoyl 1069.9 natural. 1405.1 / 1534.3 = 0.92.
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

Sucrose is esterified with vegetable stearic acid and then acetylated with acetic anhydride, which counts as petrochemical. A fermentation-acetic-acid route is not assumed.

In plain English

A waxy sugar-fatty-acid ester used as an emollient and emulsifier. It softens skin, helps oil and water mix, and gives creams and sticks a smooth, slightly waxy feel. It is made from sucrose, stearic acid and a little acetic acid.
