A common fatty acid found in various vegetable oils, most notably palm and coconut oil. It is a strongly occlusive moisturizing, emollient, and emulsifying ingredient.

Myristic 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. It is a very common fatty acid.
Myristic acid in skincare products helps to maintain the barrier function of the skin, prevents transepidermal water loss, is moisturizing (occlusive), and is an emollient. Since it is a saturated fatty acid, it is strongly occlusive, and so may not be suitable for very oily or acne-prone skin. It is also emulsifying, meaning that it helps water to mix with oil in a skincare product.
Myristic acid is mostly used in the production of soap. Various myristic acid salts are created (sodium myristate and potassium myristate are the most common) during the salt-making process. This means that a fatty acid turns into a soap molecule that cleans, foams, and works as a detergent.
The best source of myristic acid is various kinds of vegetable oils, notably palm and coconut oil.
