Aluminum Myristates/Palmitates

What is Aluminum Myristates/Palmitates?

Aluminum Myristates/Palmitates is a cosmetic-grade compound formed by reacting aluminum with myristic acid (a 14-carbon saturated fatty acid) and palmitic acid (a 16-carbon saturated fatty acid), both commonly sourced from vegetable oils like palm or coconut. It appears as a fine white powder and belongs to the category of metallic soaps used primarily in makeup products such as powders, foundations, and creams. In formulations, it works by adsorbing onto particle surfaces to inhibit moisture absorption and agglomeration, ensuring smooth flow in dry blends. It also reinforces emulsion interfaces to maintain separation of oil and water phases, adjusts rheological properties for better spreadability, and scatters light to impart a uniform, non-transparent finish.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Anticaking agent

Prevents powders from clumping by reducing moisture pickup and improving flow, keeping loose and pressed powders uniform during storage and use.

Emulsion stabilizer

Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.

Viscosity controlling agent

Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Opacifying agent

Makes a formula less transparent to create a creamy, opaque look; can also help visually mask suspended particles and improve aesthetic uniformity.

Benefits

Enhances powder flow and uniformity by absorbing excess moisture to prevent clumping.

Supports stable emulsions by strengthening droplet barriers against separation.

Improves product texture and appearance through viscosity adjustment and opacity.
