What it is
Magnesium Palmitoyl Glutamate is the magnesium salt of an acyl glutamate, made by combining the amino acid glutamic acid with palmitic acid. It is a mild, biodegradable surfactant often used together with related sodium and potassium acyl glutamates to form lamellar emulsifier systems. In sunscreens it helps emulsify oil and water phases and contributes to a smooth, gentle texture.
Safety & warnings
Amino-acid-based (acyl glutamate) surfactants are regarded as mild and are commonly chosen for sensitive-skin formulas. It is not a recognized fragrance allergen and is not considered comedogenic.
Origin & sourcing
Synthetic; produced by acylation of glutamic acid with palmitic acid (a fatty acid that can be plant- or animal-derived) and neutralization with a magnesium base.
