Nylon-6

What is Nylon-6?

Nylon-6 is a synthetic polymer from the polyamide group, formed by ring-opening polymerization of caprolactam monomer. It typically exists as fine powders or microspheres in cosmetic products, especially makeup like foundations, powders, and mascaras, but also in some skincare creams and lotions. In formulations, it acts by increasing the solid content to add bulk and structure, scattering light to reduce transparency for a smooth, creamy aesthetic, and influencing flow properties to ensure even spreading and stability. These attributes make it valuable for achieving desirable sensory profiles without compromising product integrity, supporting consistent performance during use.

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

Enhances product volume and structure for improved handling and application.

Provides opacity to create a uniform, appealing visual texture.

Controls thickness to promote stability and smooth dispensing.
