What it is
Murumuru seed butter is a solid-to-soft fat obtained from the seeds of Astrocaryum murumuru, a palm native to the Amazon basin, and is notable for its high content of lauric and myristic fatty acids. In cosmetics it functions as an emollient and occlusive that softens skin, conditions lips, and adds structure and body to balms and creams. In a lip balm or sunscreen base it helps create a smooth, cushioned texture and a protective surface film.
Safety & warnings
Murumuru butter is generally well tolerated and is widely used in lip and body products. Because it is rich in saturated fatty acids and forms an occlusive film, very acne-prone individuals may prefer to limit heavy use on the face, though it is commonly considered low-to-moderate in pore-clogging potential. It is not a recognized fragrance allergen.
Origin & sourcing
Natural; a fat expressed from the seeds (kernels) of the murumuru palm, Astrocaryum murumuru, native to tropical South America.
