Castoryl Maleate
What is Castoryl Maleate?
Castoryl Maleate is a modified derivative from castor oil sourced from Ricinus communis seeds. It forms through hydrogenation of the oil followed by reaction with maleic anhydride, creating a maleate ester. This synthetic ingredient belongs to emollient categories in cosmetics, commonly appearing in moisturizers, lip products, and creams. It functions by depositing a lightweight film on the skin's surface, which helps lock in moisture, enhances suppleness, and improves overall texture without heavy greasiness. As a conditioning agent, it interacts with the skin's lipid barrier to support natural flexibility and prevent dryness. Its chemical structure allows compatibility in various formulations, aiding product spreadability and stability.
