Hydrogenated Castor Oil Isostearate
What is Hydrogenated Castor Oil Isostearate?
Hydrogenated Castor Oil Isostearate is a derivative of castor oil that has undergone hydrogenation and esterification with isostearic acid. This process stabilizes the oil, making it less prone to rancidity and more suitable for use in cosmetic products.
It is commonly used as an emulsifier in makeup and skincare products, helping to blend water and oil components for a smooth and even texture. Scientific evaluation of its health effects is minimal, but as a cosmetic ingredient, it is generally considered safe for topical use.
For consumers, when Hydrogenated Castor Oil Isostearate appears on a label, it typically serves to enhance the product's texture and stability, with limited health implications as it is not ingested.
Commonly found in: lipstick, foundation, eyeshadow, facial cream, sunscreen
Hydrogenated Castor Oil Isostearate is permitted for use in cosmetics, with no specific restrictions noted.
Research on topical application shows no significant health risks, but studies are limited mainly to its functional properties in cosmetics.
Derived from plant-based castor oil, it is considered vegan-friendly.
