TLDR Polymer complexation makes hyaluronic acid stick to hair better, enhancing its moisturizing effects.
The study explored the enhanced substantivity of hyaluronic acid on keratin substrates through polymer complexation with cationic polymers, specifically polyquaternium-10. This complexation resulted in a stable, multifunctional association that improved the functionality of hyaluronic acid. The research demonstrated that the complex increased the binding of hyaluronic acid to hair by up to ten times after rinsing, as shown by radiolabelling techniques. This enhanced binding prolonged the humectant, moisturizing, and skin-smoothening effects of hyaluronic acid on keratinous surfaces.
