Nylon 6/12

What is Nylon 6/12?

Nylon 6/12 is a synthetic polyamide polymer derived from hexamethylenediamine and dodecanedioic acid, forming a copolymer with 6 and 12 carbon units in its chain. Produced through polycondensation, it appears as fine, porous microspheres or powders in skincare and makeup products. Primarily found in powders, foundations, and lotions, it functions by trapping moisture and oils within its structure due to high porosity, aiding in mattifying effects. As a bulking agent, it enhances product volume and spreadability without heaviness. Its opacifying property scatters light to reduce transparency, improving visual appeal and uniformity in formulations. This versatile ingredient supports lighter, drier finishes in oil-control products.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Absorbent
Absorbs water and/or sebum to reduce greasiness and shine, improve dry touch, and help keep powders and emulsions feeling lighter on skin.
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.

Benefits

Absorbs excess sebum to minimize shine and greasiness on skin.

Adds volume and improves texture for smoother application and feel.

Provides opacity to create a uniform, creamy appearance in products.
