Mechanism of Action
Comprised of polyethylene glycol (PEG) and Nylon-6, this ingredient functions through a dual mechanism. The PEG component acts as a humectant, attracting and binding water molecules to the stratum corneum via hydrogen bonds, thereby reducing transepidermal water loss and supporting the skin's natural barrier. Concurrently, the Nylon-6 component forms a thin, non-occlusive layer of spherical microparticles on the skin surface. This layer provides a refined, silky tactile sensation and, due to its inherent porosity and lipophilic nature, is capable of absorbing excess water and sebum. Furthermore, Nylon-6 exhibits adsorptive and desorptive properties, enabling it to effectively retain and progressively release active ingredients or emollients within a formulation over time.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed polyethylene glycols (PEGs) and nylon polymers, including Nylon-6, safe for use in cosmetic formulations under current practices, noting their minimal skin penetration. While Nylon-6 was reported at concentrations up to 20% in eyebrow pencils, a general maximum concentration for this specific crosspolymer in skincare is not specified. The FDA has approved Nylon-6, Nylon-66, and PEG compounds for various applications, including indirect food additives and medical devices.
