Astrocaryum Murumuru Seed Butter

What is Astrocaryum Murumuru Seed Butter?

Astrocaryum Murumuru Seed Butter derives from the seeds of the Astrocaryum murumuru palm, a tree native to the Amazon rainforest in South America. This plant-based ingredient is a semi-solid fat obtained through cold-pressing and refining the seed kernels, resulting in a rich blend of triglycerides primarily composed of lauric, myristic, oleic, and stearic fatty acids. In cosmetics, it belongs to the emollient and occlusive category, commonly featured in moisturizers, lip balms, body creams, and hair care products. Upon application, it melts at skin temperature, forming a protective barrier that mimics the skin's natural lipids. This action helps fill in surface imperfections, improve product spreadability, and minimize transepidermal water loss, while imparting a non-greasy, velvety texture.
