Ricinus Communis (Castor) Seed Oil
Ricinus Communis (Castor) Seed Oil is a thick, nourishing plant oil widely used in UK beauty products for its ability to moisturise, condition and create a protective barrier on skin and hair.
How it works in skincare
In cosmetics and skincare, Ricinus Communis (Castor) Seed Oil functions as an emollient, occlusive and viscosity-increasing agent. Its unique ricinoleic acid content gives it a slightly sticky texture that helps lock in moisture, smooth rough patches and improve the glide and cushion of lipsticks, balms, mascaras and hair treatments. It is valued in British formulations for delivering long-lasting softness without feeling overly greasy when used at the right levels.
