Cationic modification gives HA a positive charge, allowing it to naturally bind to negatively charged skin and hair surfaces for significantly higher deposition and retention.
In hair care products, cationic HA adheres better to damaged hair fibers, providing exceptional moisture, repair, and anti-static effects.
Compared to standard HA, it remains on the skin surface for longer periods, maintaining part of its moisturizing effect even after wash-off.
A controlled cationic degree (0.15–0.60, measured 0.42) ensures stable performance and consistency across batches.
With protein content ≤ 0.1% and transmittance ≥ 99%, it meets all safety requirements for advanced cosmetic formulations.
Stable within pH 5.0–8.5 and compatible with cationic surfactant systems and hair conditioner formulas.
Strong affinity for damaged hair, serving as a premium moisturizing ingredient with anti-static and smoothing benefits.
Acts as a hair care active in shampoos, reducing fiber damage during cleaning and improving post-wash smoothness.
Higher deposition rate on the skin than standard HA, perfect for high-efficiency moisturizing toners and serum formulations.
Provides long-lasting hydration in leave-on products due to its positive charge extending retention time on the skin.
Enhanced skin penetration and lipophilic compatibility for premium anti-aging products.
