Science
Mechanism of Action
As a cationic polymer, Polyquaternium-47 creates a cohesive, protective film across the skin's surface. This film serves to minimize transepidermal water loss, thereby sealing in moisture and refining skin texture. Its inherent positive charge enables robust ionic bonding to the skin, leading to sustained hydration and a noticeably softer, more supple feel.

The Formula
Formulation
Stability
Polyquaternium-47 demonstrates excellent stability within a pH range of 3 to 7. It should be incorporated into the water phase during formulation. While it exhibits heat tolerance, temperatures exceeding 80°C should be meticulously avoided. Optimal storage conditions involve room temperature, protected from direct sunlight, excessive heat, and moisture.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) panel has deemed Polyquaternium-47 safe for use in cosmetics, provided it is formulated to be non-irritating and utilized within recommended concentration limits, typically 0.5% to 2%. It is widely recognized as mild, non-irritating to both skin and eyes, and universally well-tolerated by most skin and hair types, including sensitive complexions. Adverse reactions are infrequent; nevertheless, a preliminary patch test is always advised prior to full application.
