Mechanism of Action
As a cationic polymer, SILICONE QUATERNIUM-28 carries a positive charge, enabling it to adhere to the negatively charged surfaces of hair, thereby providing conditioning, detangling, frizz reduction, and imparting shine and softness. More broadly, silicones form a breathable barrier on the skin, which can improve skin texture, provide a smooth feel, and aid in product distribution.

Stability
While specific pH stability for SILICONE QUATERNIUM-28 is not directly reported, related silicone quaternary compounds and polyquaterniums typically exhibit stability within a slightly acidic to neutral pH range, often between pH 4 and 8. Silicones as a class are known for their high inherent stability.
Safety
Safety Profile
SILICONE QUATERNIUM-28 has not been individually assessed by the CIR Expert Panel. However, the panel has extensively evaluated numerous related silicone compounds, generally concluding their safety for cosmetic use. These broader assessments often cite low allergenicity, non-irritating, and non-comedogenic properties for silicones. The FDA recognizes dimethicone, a related silicone, as a Category 1 safe and effective skin protectant at concentrations up to 30%.
