What Hydrogenated Castor Oil Isostearate is & what it does
Hydrogenated Castor Oil Isostearate is the isostearic acid ester of hydrogenated castor oil, a waxy, oil-soluble material. In a skincare or sunscreen formula it serves as an emollient and texture agent, giving a smooth, cushioned glide and helping disperse pigments and oils. Its hydrogenated structure makes it relatively stable against oxidation.

Is Hydrogenated Castor Oil Isostearate comedogenic?
There is limited specific data on the comedogenicity of Hydrogenated Castor Oil Isostearate, so a firm rating cannot be given. As a heavier ester derived from castor oil, very acne-prone users may prefer to monitor how their skin responds. Many people tolerate it well in balanced formulas.
Is Hydrogenated Castor Oil Isostearate vegan?
Hydrogenated Castor Oil Isostearate is plant-derived, made from castor oil that comes from castor bean seeds, so the ingredient itself is not animal-sourced. Whether a finished product is fully vegan still depends on its other ingredients. Check the product's labeling to confirm.
