Stability
Most stable in the pH range of 4.0 to 9.0. It typically requires neutralization with alkanolamines (e.g., TEA) to achieve full solubility and viscosity in aqueous systems.
Synergies
- Other copolymers (for enhanced moisture resistance)
Conflicts
- Cationic surfactants
- Strong electrolytes (high salt concentrations)
- Strongly acidic environments (below pH 3.0)
Safety
Safety Profile
Generally recognized as safe, its high molecular weight (>10,000 Da) minimizes skin penetration and systemic toxicity.
