Science
Mechanism of Action
Polyamide-6 operates by increasing product volume and density while precisely controlling viscosity, thereby optimizing the spreadability and absorption of formulations. It forms a uniform, non-occlusive layer of spherical particles on the skin, imparting a refined, silky tactile experience. Its inherent porous and lipophilic characteristics render it effective for sebum absorption and control. Furthermore, Polyamide-6 exhibits adsorptive and desorptive properties, enabling the controlled retention and release of active ingredients or emollients over time.

The Formula
Formulation
Stability
Polyamide-6 exhibits chemical inertness at pH 7 and demonstrates resistance to oils, gasoline, alcohol, weak acids, and both dilute and concentrated alkalis. While not considered water-soluble, it is hygroscopic and can absorb up to 2.4% of its weight in water, which may influence its properties. High temperatures in conjunction with water can lead to degradation of its mechanical integrity.

Safety
Safety Profile
The CIR Expert Panel concluded Polyamide-6, along with other Nylon polymers, is safe for use in cosmetic and personal care products. This assessment is based on its minimal potential for skin penetration due to large polymer size and a low association with irritation or sensitization. Its monomer, caprolactam, was found not to be genotoxic or carcinogenic. Polyamide-6 also holds FDA approval for indirect food contact and non-absorbable surgical sutures.
