Science
Mechanism of Action
As a positively charged (cationic) polymer, Polyquaternium-92 neutralizes the inherent negative charges present on both hair and skin surfaces. This neutralization enables an ionic bond to form, creating a protective film. Certain polyquaterniums are also observed to attract environmental moisture, acting as humectants.

Safety Profile
Specific safety assessments for Polyquaternium-92 by major regulatory bodies like CIR, SCCS, or FDA are currently unavailable. Dermal, oral, and inhalation toxicity for Polyquaternium-92 are listed as 'Not determined'. However, the CIR Expert Panel has evaluated several other polyquaterniums (e.g., -6, -11, -22, -39) and deemed them safe for cosmetic use within current practice and concentrations. The CIR consistently highlights the importance of data regarding residual monomers and polymerization profiles for a complete polyquaternium safety assessment.

Verdict
Due to the absence of specific safety assessments and clinical efficacy studies for skin, the integration of Polyquaternium-92 into precision skincare formulations cannot be fully endorsed or optimized at this time.
