Mostly natural · ISO 16128

Is MIPA-Lauryl Sulfate natural?

Mostly. The lauryl sulfate anion comes from an oleochemical C12 alcohol and mineral sulfate; the MIPA counter-ion is a synthetic petrochemical amine.

How we scored it

Dodecyl sulfate anion 266.4 (natural: oleochemical C12 alcohol + mineral sulfate) + MIPA cation 75.1 (synthetic amine, petrochemical) = 341.5; 266.4/341.5 = 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

Made by sulfating a coconut or palm-kernel derived lauryl alcohol and neutralising with monoisopropanolamine, a petrochemical alkanolamine. The lauryl chain could alternatively be a synthetic Ziegler/oxo alcohol, worth a supplier check.

In plain English

A cleansing surfactant made from a coconut or palm-derived fatty alcohol combined with a synthetic amine base. It helps products foam and remove oil and dirt from skin and hair.
