Castoryl Maleate is primarily an emollient, skin conditioning agent, and film forming ingredient that comes from castor oil and maleic acid. It has a softening and smoothing effect on the skin and helps maintain the suppleness by forming a barrier that traps moisture. It feels lightweight on the skin making it valuable in formulations like creams, lotions, foundations, and mascaras. In its raw form, Castoryl Maleate appears as a viscous, oily liquid or semi-solid wax-like substance with a pale to amber color. Its texture is smooth and rich, allowing it to blend easily into cosmetic formulations, particularly oil-based and emulsified products. The chemical formula of Castoryl Maleate is C61H106O12.

What is CASTORYL MALEATE used for?
Castoryl Maleate has emollient properties that make it highly beneficial in personal care. It forms a lightweight and breathable barrier on the surface of the skin that locks in moisture and keeps the skin smooth and hydrated.

Origin
Castoryl Maleate is produced through an esterification process where castor oil reacts with maleic acid. Under controlled heat and sometimes with a catalyst, the hydroxyl groups in castor oil bond with maleic acid, forming the ester known as Castoryl Maleate. This reaction modifies the properties of castor oil, giving it enhanced stability and film-forming abilities, which are beneficial in cosmetic formulations.
