Myrianthic acid is widely used in the cosmetics and personal care industry as an emulsifying agent and emollient. It helps stabilize formulations by allowing oil and water to mix, improving the texture and consistency of lotions, creams, and makeup products. In soaps, it contributes to hardness and lathering properties.

In the food industry, myristic acid is used as a flavoring agent and additive, enhancing the taste and aroma of processed foods. It is also a key component in the production of esters used in fragrances due to its ability to carry and release scent effectively.

Pharmaceutically, myristic acid plays a role in drug delivery systems, particularly in the modification of proteins and peptides through a process called myristoylation, which can influence cellular targeting and activity of therapeutic molecules. Additionally, it is used in the synthesis of various active pharmaceutical ingredients and as a coating agent in tablet formulations.
