Polyamide-5
What is Polyamide-5?
Polyamide-5 is a synthetic polymer from the polyamide family, formed by polymerization of diamines and dicarboxylic acids, akin to nylon structures. In cosmetics, it primarily functions in the film-forming and viscosity-controlling categories. It creates a flexible, adherent film on skin, hair, or nails, helping to encapsulate active components, improve product spreadability, and extend wear duration. Typically incorporated into makeup like lip products and mascaras, hair fixatives, and nail formulations, it contributes to smooth texture, water resistance, and structural integrity without greasiness. This makes it ideal for performance-driven products where stability and sensory qualities matter.
Benefits
Forms durable, flexible films for prolonged product wear
