How we scored it
Lauroyl C12H23O 183 Da (coconut/palm kernel) + lactyl O-CH(CH3)-COO 88 Da (fermentation lactic acid) + Na 23 Da = 294 Da; caproyl analogue likewise; all 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
Fatty acids from coconut or palm kernel oil are esterified with lactic acid from sugar fermentation and neutralised with sodium hydroxide. Synthetic lactic acid is a minor alternative that does not change the common commercial grade.
In plain English
A surfactant and emulsifier made by joining coconut or palm kernel fatty acids to lactic acid and neutralising with sodium. It cleanses, emulsifies and helps limit microbes and oiliness on skin. Its parts come from plant oils and fermented sugar.
