Palmitic Acid 98% min
EDENOR® C16-98 MY
Cosmetic & Technical grade
Palmitic acid is one of the most common naturally occurring saturated fatty acids, widely found in animals, plants, and microorganisms. It was first isolated from palm oil (hence the name).
Palmitic acid is a 16-carbon saturated fatty acid that is solid at room temperature, chemically stable, and versatile. It plays roles in biology, and industry, with key applications in cosmetics, soaps, surfactants, and pharmaceuticals.

Uses of Palmitic Acid
-
Cosmetics & personal care
-
As emollient, thickener, or opacifying agent in creams, lotions, and soaps.
-
Its salts and esters (e.g., isopropyl palmitate) are widely used as moisturizers and skin conditioners.
-
-
Soap & detergents
-
Sodium palmitate (from saponification) is a classic soap ingredient.
-
Provides hardness and foaming stability.
-
-
Industrial uses
-
As a precursor for lubricants, surfactants, and plasticizers.
-
Used in manufacturing fatty alcohols, esters, and metallic soaps (e.g., calcium palmitate for stabilizers).
-
-
Pharmaceuticals
-
Used as an excipient in drug formulations.
-
Palmitic acid derivatives can modify drug solubility or release profile.
-
-
Biological role
-
A major energy source when metabolized.
