How we scored it
Triple ester of glycerin (fats/oils), stearic acid (vegetable/tallow) and citric acid (fermentation); all three building blocks natural-origin. 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 glycerin, a fat/oil by-product, with stearic acid from vegetable oil or tallow and citric acid from carbohydrate fermentation. All three building blocks are natural-origin.
In plain English
An emulsifying ester made from glycerin (from fats and oils), stearic acid (a vegetable or tallow fatty acid) and citric acid (a fermentation product). Helps blend oil and water in creams.
