Castor Isostearate Succinate
What is Castor Isostearate Succinate?
Castor Isostearate Succinate is a synthetic ester created by combining succinic acid with fatty acids from castor oil and isostearic acid. Castor oil comes from Ricinus communis seeds and supplies ricinoleic acid, a hydroxylated fatty acid, while isostearic acid arises from rearranging stearic acid chains for branching. This results in a lipophilic compound used mainly in moisturizers, lotions, and creams as part of emollient systems. It acts as a skin conditioning agent by depositing a thin, non-greasy film on the skin surface. This film diminishes moisture evaporation, bolsters the natural barrier, and imparts a soft, pliable texture. Due to its balanced polarity and low comedogenicity, it integrates well into emulsions, aiding product spreadability and stability without heaviness. Formulators value it for enhancing sensory attributes in leave-on products, supporting overall skin comfort across various formulations.
