Butters and waxes are mainly natural ingredients widely used in cosmetics to provide moisture, smoothness, texture, and protection to the skin. They help form a barrier that prevents water loss, enhance product consistency, and add a smooth, luxurious feel. Waxes like beeswax, carnauba wax, and candelilla wax create structure in products like balms and lipsticks, while butters such as shea butter, cocoa butter, and mango butter add a thick, creamy feel and are excellent emollients.
