Myristyl myristate is the ester derived from myristyl alcohol and myristic acid.[2]
Properties
It has the molecular formula C28H56O2 and a molecular weight of 424.75 g/mol.[3] Myristyl myristate appears as a white to yellowish waxy solid with a melting point just above body temperature (40–44 °C).[1] Myristyl myristate is insoluble in water,[1] but soluble in oils. It functions as a non-greasy emollient that melts near skin temperature, imparting a soft, slightly waxy feel.[2]
Uses
Myristyl myristate is primarily used in cosmetics and personal care products as an emollient, texture enhancer, and skin-conditioning agent. It improves the spreadability and stability of emulsions, adds body to creams and lotions, and provides a velvety skin feel.[2]
Safety
Acute oral and dermal toxicity tests in animals indicate that myristyl myristate is nontoxic.[2][4] The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that myristyl myristate is safe as a cosmetic ingredient in the present uses and concentrations.[2]
