Nylon-12

What is Nylon-12?

Nylon-12 is a synthetic polyamide polymer produced from laurolactam, featuring a chain of 12 carbon atoms, resulting in fine, spherical white particles. Commonly found in makeup such as foundations, powders, and mascaras, it serves in color cosmetics and personal care formulations. In products, it functions by absorbing oils for a matte finish, expanding volume to enhance spreadability, and scattering light to create an opaque, uniform appearance. Its small, uniform spheres improve slip and reduce tackiness during application, while modifying flow properties to prevent separation in suspensions. Chemically inert, it remains stable across pH ranges and temperatures, making it versatile for anhydrous and aqueous systems without altering active ingredients.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Bulking agent
Increases mass/volume to build structure and improve handling, commonly used to adjust feel, spread, and cost-in-use without acting as a primary active.
Opacifying agent
Makes a formula less transparent to create a creamy, opaque look; can also help visually mask suspended particles and improve aesthetic uniformity.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Builds structure for easier handling and application in powders and creams.

Creates a creamy, non-transparent look to mask imperfections visually.

Stabilizes thickness to support even distribution and product integrity.
