Science
Mechanism of Action
This synthetic cationic polymer functions by leveraging its positive charge, which creates an attraction to the slightly negatively charged proteins found on skin and hair. Upon application, it forms a continuous, protective film that aids in moisture retention, promoting hydration and a smoother skin feel. Furthermore, within cleansing formulations, this film can help mitigate the potential drying or irritating effects of harsh surfactants, thereby making products gentler on the skin.

The Formula
Formulation
Stability
Polyquaternium-76 maintains stability and remains ionized within an environmental pH range of 4.0 to 9.0, supporting its integrity under typical use and storage conditions.
Synergies
- Co-formulation with anionic surfactants can mitigate potential irritant effects, enhancing product mildness.
Conflicts
- Potential incompatibility with anionic surfactants, which may result in precipitation or haze if not carefully formulated.
- Sensitivity to pH and temperature outside the optimal range (4.0-9.0), potentially impacting solubility and leading to precipitation.
- High concentrations may pose challenges for solubilization within water-based systems.
Safety
Safety Profile
Safety assessments indicate a low acute toxicity concern and minimal dermal absorption due to its high molecular weight. At concentrations up to 0.5% in products, Polyquaternium-76 is not anticipated to cause skin or eye irritation or sensitization. This safety profile is particularly enhanced when co-formulated with anionic surfactants, which are known to reduce potential irritant effects.
