Aluminum Myristate

What is Aluminum Myristate?

Aluminum myristate is the aluminum salt derived from myristic acid, a saturated fatty acid typically sourced from coconut or palm kernel oils. This fine white powder appears in various cosmetic formulations, particularly dry powders like face powders and eyeshadows, as well as creams and lotions. It works by absorbing excess moisture to inhibit clumping in powders, ensuring even texture and easy application. In liquid or semi-solid products, it strengthens emulsion structures to prevent separation, while also adjusting viscosity for optimal spreadability and stability. Its inert nature allows it to integrate seamlessly without altering color, scent, or primary active components, making it a versatile aid in achieving consistent product performance across makeup and skincare items.

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.

Benefits

Maintains powder uniformity by absorbing moisture and preventing lumps for smooth, even application.

Enhances emulsion durability to keep creams and lotions blended without separating over time.

Optimizes product thickness for better texture, spreadability, and overall user experience.

Who It's For

Who May Benefit Who Should Avoid
Users of loose or pressed powders seeking clump-free products.
People with rare aluminum sensitivities, as patch testing is advisable.
Individuals applying emulsion-based moisturizers or foundations for lasting stability.
Individuals with compromised skin barriers where absorption might increase.
Those preferring adjustable textures in daily skincare and makeup routines.
Those preferring aluminum-free formulations for personal choice.

Safety Notes

  • Rated low hazard by safety assessments for cosmetic use.
  • Non-comedogenic, unlikely to clog pores in typical concentrations.
