How we scored it

Potassium salt of oleic acid; oleic acid natural (vegetable oil) + K natural counter-ion. 1.0.
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

Potassium Oleate is made by neutralising vegetable-oil-derived oleic acid with potassium hydroxide, typically to make soft or liquid soaps. Both fragments are natural origin.

In plain English

The potassium salt of oleic acid, a fatty acid from vegetable oils. Used as a cleansing and emulsifying agent, commonly in soft or liquid soaps.
