Overview

Palmitic acid is a fatty acid, meaning that it is an acid with a long, oil-soluble tail. It is specifically a saturated fatty acid, which means that its oil-soluble tail only contains single bonds. It is a waxy-looking, white solid.

Palmitic acid is used in skincare products to help to maintain the barrier function of the skin, prevent transepidermal water loss, and as an emollient.

The acid is strongly occlusive (since it is a saturated fatty acid). It tends to feel very heavy and thick on the skin and so is usually used together with other emulsifiers. It also helps in the formulation of the skincare product.

Palmitic acid is the most common saturated fatty acid in nature and can widely be found in vegetable and animal fats. The best source of palmitic acid for the industry is palm oil.

Palmitic acid is very often used for the production of soap. It is also emulsifying, meaning that it helps water and oil to mix in the skincare product.
