Science
Mechanism of Action
As a positively charged cationic polymer, POLYQUATERNIUM-44 forms an ionic bond with the naturally negatively charged sites on the skin and hair surface. This interaction creates a fine, protective layer that not only contributes to a noticeably smoother skin texture but also effectively minimizes transepidermal water loss, thereby fortifying the skin's natural barrier against environmental stressors. It can also function as a humectant, attracting and binding atmospheric moisture to the skin to enhance hydration and mitigate dryness. Furthermore, POLYQUATERNIUM-44 plays a critical role in optimizing product performance by improving the spreadability of skincare formulations and stabilizing emulsion-based products through interaction with both oil and water phases. It is notably mild, reducing the irritation potential of co-formulated surfactants.

Conflicts
- Generally, cationic polymers may complex with anionic polymers or surfactants due to opposing electrostatic charges. However, Polyquaternium-44 is specifically noted for its excellent solubility in and compatibility with a wide array of surfactants, mitigating typical incompatibility concerns.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has generally deemed polyquaternium compounds safe for use, and Polyquaternium-44 is approved by various global regulatory bodies. While considered exceptionally mild with low irritancy, a patch test is recommended for individual sensitivity assessment.
