Myristic Acid: Fatty Acid with a Myriad of Benefits
Myristic acid is one of the fatty acids found in living organism, from bacteria, plants, to animals. These fatty acids can be found in animal and vegetable fats, especially butterfat, coconut oil, palm oil, and nutmeg oil. Most of the seed oils from Myristaceae family contain up to 80% myristic acid .
Structurally, myristic acid has a long chain with an aliphatic tail and contains 14 carbon atoms. Thus, this fatty acid, which is in the form of white or faintly yellow crystal / powder at room temperature, has hydrophobic properties . Therefore, generally myristic acid is used in the industry as:
PVC heat stabilizers
Many people may have used products with myristic acid without knowing as it is a common ingredients used in many consumer goods [3,4]:
In cosmetics, myristic acid has several roles, for instance: surfactant, lubricant, emulsifier, an opacifying agent, or a cleaning agent.

In addition, myristic acid provides a better coverage in reducing the appearance of pimples and blemishes in concealer and foundation products. The lubricant properties of the myristic acid is very important because of its high rate of absorption on the skin.
2. Soaps dan detergents
Myristic acid can act as a surfactant. It can mix with water and oily dirt particles, and can be easily rinsed off. This component can also create foams for cleansing.
When myristic acid is synthesized into ethyl myristate, it has a nice aroma that can be used in fragrance application.
4. Skincare and hair care
As surfactant, myristic acid can mix with water and oil to remove dirt and impurities on the skin, hair, scalp, etc. while keeping the skin hydrated.
