Calophyllum Inophyllum (Alexandrian Laurel) Seed Oil

What is Calophyllum Inophyllum (Alexandrian Laurel) Seed Oil?

Calophyllum Inophyllum Seed Oil, widely known as tamanu oil, comes from the ripe seeds of the Calophyllum inophyllum tree, a tropical evergreen species from the Clusiaceae family native to Southeast Asia, India, and Pacific islands. This golden-green oil is typically obtained through cold-pressing and contains a mix of fatty acids including oleic, linoleic, and stearic acids, plus specialized compounds like calophyllolide and inophyllum. In cosmetic products, it functions as an emollient, spreading easily to form a breathable film that helps retain moisture and improve texture. It also acts as a stabilizer against oxidation in formulations and provides conditioning for hair shafts. Found in moisturizers, serums, shampoos, sunscreens, and oral care items, it supports product integrity and sensory feel without greasiness.
