Lauric Acid

A fatty acid derived from various vegetable oils such as palm or coconut oil. It helps to maintain the barrier function of the skin and is also used as a cleansing or emulsifying agent. Lauric acid is listed among common comedogenic ingredients by acne.org.

Overview

Lauric acid is a fatty acid, meaning that it is an acid with a long, lipid-soluble tail. It is specifically a saturated fatty acid, which means that its oil-soluble tail only contains single bonds.

Lauric acid is used in skincare products to help maintain the barrier function of the skin. It has a faint, bay leaf-like scent, which is sometimes used to create the final scent of the skincare product.

It is also emulsifying, meaning that it helps water to mix with oil in a skincare product, and cleansing, meaning that it helps remove the oily impurities from the skin’s surface.

Some research suggests that it may have mild anti-acne properties, as it acts against the bacteria causing inflammed acne spots.

Lauric acid can be chemically modified to create various derivatives which are used as soap or detergents: sodium laurate and potassium laurate are simple salts of lauric acid, while the commonly used sodium laureth sulfate is a more complicated chemical derivative.

The best source of myristic acid is various kinds of vegetable oils, notably palm and coconut oil.
