Uses
palmitic acid is one of the skin’s major fatty acids produced by the sebaceous glands. In cosmetic preparations, it is used as a formula texturizer. This acid is naturally occurring in allspice, anise, calamus oil, cascarilla bark, celery seed, coffee, tea, and many animal fats and plant oils. It is obtained from palm oil, Japan wax, or Chinese vegetable tallow.
