What it is
Myristic Acid is a fatty acid naturally found in some foods and oils such as coconut oil, pal oil and nutmeg.
What it does
Myristic Acid is a surfactant: it helps water mix with oil and dirt so that they can be rinsed away. It foams well.
In addition, it is used as an opacifying agent: it reduces the clear appearance of cosmetics, such as concealers formulated to hide blemishes.
Myristic Acid is moderately comedogenic.
