Is Disodium Laneth-5 Sulfosuccinate natural?

Mostly. Lanolin alcohol and the sulfonate/sodium groups are natural; the ethylene-oxide chain and maleic-derived succinate backbone are petrochemical.

How we scored it

Lanolin alcohol (~270 Da, natural) + 5 EO (220 Da, petrochemical) + sulfosuccinate cap (SO3Na+COONa natural 126 Da, succinate backbone 115 Da petrochemical). Natural 396/731=0.54.
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

Lanolin (wool grease) alcohols are ethoxylated with about 5 mol ethylene oxide, then capped with a sulfosuccinate group and neutralised with sodium. Fragment weights are estimated from typical lanolin alcohol composition.

In plain English

A mild cleansing surfactant made from lanolin (wool grease) alcohols reacted with ethylene oxide and a sulfosuccinate group, sold as a sodium salt. Used to boost foam and gentleness in cleansers.
