Hydrogenated Castor Oil Dimer Dilinoleate

What is Hydrogenated Castor Oil Dimer Dilinoleate?

Hydrogenated Castor Oil Dimer Dilinoleate is a specialized ester produced by combining hydrogenated castor oil, derived from the seeds of the Ricinus communis plant, with dilinoleic acid, a dimer formed from linoleic acid in plant oils. This creates a thick, waxy substance categorized as an emollient and conditioning agent in cosmetics. It appears in anhydrous formulations such as lipsticks, mascaras, hair pomades, and skin balms. Functionally, it binds powders and pigments into cohesive solids, enhancing product durability and ease of application. As a conditioner, it deposits a thin, occlusive layer on skin and hair shafts, reducing friction for better slip and manageability while shielding against moisture loss and irritants without greasiness.
