Science

Mechanism of Action

This ingredient functions through its unique microporous structure and high specific surface area, allowing it to efficiently absorb excess oil and reduce skin shine, thereby creating a mattifying effect. Beyond oil control, NYLON-10/10 contributes to a soft-focus illusion, visually minimizing fine lines and minor skin irregularities, while also enhancing the tactile properties and wear of cosmetic formulations.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has broadly deemed large, stable, non-water-soluble nylon polymers, including structurally similar variants, to be safe for cosmetic use. These polymers are not expected to penetrate the skin or induce systemic toxicity, and are considered non-irritating and non-sensitizing. While specific use concentrations for NYLON-10/10 are not yet widely reported, its characteristics align with other FDA-approved nylons used in various applications.
