How we scored it
Each arm: stearic acid 284.5 + 2x lactic acid 90.1 - 2 H2O(condensation) ~428; x2 arms + Ca 40.1 ~895 Da matches given MW; all fragments natural → 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
Made by esterifying vegetable-oil stearic acid with fermentation-derived lactic acid, then neutralising with calcium. No petrochemical route is used commercially.
In plain English
An emulsifier made from plant fat (stearic acid) and fermented sugar (lactic acid), bound to calcium. It helps mix oil and water and gives creams a smooth texture.
Structure
calcium bis(2-(2-octadecanoyloxypropanoyloxy)propanoate)
