SILICONE QUATERNIUM-28.

Insufficient Data / HAIR CONDITIONING

SILICONE QUATERNIUM-28 is a silicone quaternary polymer primarily recognized for its advanced conditioning properties. It contributes to a smoother feel and enhanced spreadability by forming a protective, vapor-permeable film on surfaces.

Science

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

Sensitization risk Low

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%.
