Science
Mechanism of Action
This copolymer's primary mechanism involves creating a thin, continuous film on the skin or hair, acting as a protective barrier and enhancing product wear. It also reduces the bulk density of cosmetic agents through swelling properties and minimizes transparency with opacifying effects. By precisely regulating viscosity, it contributes to improved water resistance, long-term stability, and skin moisture retention while reducing unwanted stickiness. In complex formulations like sunscreens, it aids in dispersing and stabilizing ingredients, effectively preventing the formation of white residues.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Nylon-12, Nylon-6, Nylon-66, and their copolymers, including Nylon-12/6/66 Copolymer, are safe for use in cosmetics under current practices. While specific use concentrations for this copolymer were not reported, related nylons have received FDA approval for indirect food contact and non-absorbable surgical sutures, indicating a favorable safety profile. The CIR noted a lack of specific data regarding potential residual monomer content for this ingredient.
