What is Palm Kernel Acid?

Palm kernel acid consists of a mixture of saturated fatty acids, primarily lauric acid, myristic acid, and palmitic acid, obtained from the oil extracted from palm kernels (Elaeis guineensis). This natural-derived ingredient typically presents as a waxy solid and is widely incorporated into rinse-off products like shampoos, body washes, and bar soaps. It works by decreasing the surface tension of liquids, which facilitates the formation of micelles to lift away dirt and excess sebum during cleansing. Additionally, it stabilizes emulsions by creating a barrier at the oil-water interface, preventing separation in formulations. Its opacifying effect scatters light to impart a smooth, creamy visual texture to translucent products, enhancing their appeal without altering functionality.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Opacifying agent
Makes a formula less transparent to create a creamy, opaque look; can also help visually mask suspended particles and improve aesthetic uniformity.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Cleansing agent
Removes dirt, oil, and impurities by lowering surface tension and forming micelles, enabling soils to be lifted and rinsed away from skin, hair, or teeth.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

- Offers softening action to improve skin feel and flexibility.
