Calophyllum Tacamahaca (Tamanu) Seed Oil

What is Calophyllum Tacamahaca (Tamanu) Seed Oil?

Calophyllum Tacamahaca (Tamanu) Seed Oil is a plant-derived fixed oil obtained by cold-pressing seeds from the Calophyllum tacamahaca tree, native to tropical areas including parts of South America and the Pacific region. This thick, greenish oil consists mainly of triglycerides rich in oleic, stearic, and linoleic fatty acids, along with unique lipid-soluble compounds. In cosmetic formulations, it belongs to the emollient and skin conditioning category, commonly appearing in facial oils, body butters, balms, and night creams. It works by spreading evenly on the skin to mimic sebum, filling in micro-irregularities for a smoother feel, enhancing product glide during application, and aiding in moisture retention through its semi-occlusive properties when combined with other ingredients.
