Myristyl Myristate is the ester of myristyl alcohol and myristic acid. It is a white-to-yellow waxy solid with a typical waxy odor. It is soluble in mineral oils, but insoluble in water, isopropanol, ethanol, glycerol, and propylene glycol. It is produced by esterification of myristic acid and myristic alcohol in the presence of an acid catalyst. The product is stripped to remove excess s myristyl alcohol, neutralized the catalyst with alkali, and then purified to separate Myristyl Myristate[1-2].
Myristate myristate is able to be used as a wax base in cosmetics and pharmaceuticals. It is a soft wax that melts at body temperature, so it gives a velvety texture when applied to the skin. It can be added to some soaps, and excess myristic acid can produce pearl effects. At lower concentrations, it improves the spreadability of lotion cosmetics. It reduces the feeling of water in hand and body lotions.
Myristyl myristate, is one of the more used waxy esters in cosmetic formulations due to its emollient properties.
myristyl myristate is an occlusive skin-conditioning agent that enhances product spreadability and can reduce a product’s transparency. It is particularly useful in emulsions that have to “melt” once they come in contact with the skin. This is an ester formed by the combination of the myristyl alcohol and myristic acid fractions of coconut oil.
ChEBI: Tetradecyl tetradecanoate is a tetradecanoate ester (myristate ester) resulting from the formal condensation of the carboxy group of tetradecanoic acid (myristic acid) with the hydroxy group of tetradecan-1-ol (myristyl alcohol). Used as an emollient. It has a role as an algal metabolite. It is a wax ester and a tetradecanoate ester. It is functionally related to a tetradecan-1-ol.
