Science
Mechanism of Action
Operating as an advanced texturizing and softening agent, Polyamide-5 significantly improves the feel of emulsion-based products on the skin. Its micro-fine structure allows for efficient oil adsorption and enhanced pigment distribution in color cosmetics. Furthermore, its high surface area facilitates the controlled delivery of active ingredients through sorption-desorption kinetics.

Stability
Polyamide-5 maintains consistent performance across a wide pH spectrum, optimally between 4 and 11. Exposure to extremely acidic conditions (below pH 4) or highly alkaline environments (above pH 11) may compromise its stability and functional integrity.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of polyamide polymers, including Polyamide-5, for cosmetic use under current practices, citing their minimal skin penetration. Sensitization studies on structurally similar Nylon-12, even at concentrations up to 19.5% in a facial moisturizer, reported no adverse reactions, indicating a low sensitization risk. Polyamide-5 is recognized by the FDA with UNII: UEM62QMW5F.
