SILICONE QUATERNIUM-1.

Insufficient Data / ANTISTATIC, HAIR CONDITIONING

SILICONE QUATERNIUM-1 is a sophisticated silicone derivative categorized as a quaternary ammonium compound. It is engineered to impart antistatic benefits and conditioning properties, functioning in skincare to improve sensory attributes like spreadability and to deliver a soft, non-greasy finish.

Antistatic Hair conditioning Skin conditioning Spreadability enhancer

Science

Mechanism of Action

Operating as a quaternary ammonium cation, SILICONE QUATERNIUM-1 neutralizes surface electrical charges, thereby acting as an effective antistatic agent. For the skin, it is hypothesized to enhance the even distribution of formulations and contribute to a smooth, non-oily feel. In alignment with other silicones, it forms a lightweight, breathable film on the skin's surface, which can aid in moisture retention, confer a soft textural quality, and provide a 'soft focus' optical effect by subtly dispersing light to minimize the appearance of fine lines.

Stability

While a precise optimal pH range for SILICONE QUATERNIUM-1 has not been established, related silicone quaterniums demonstrate stability across a broad pH spectrum in cosmetic formulations, typically ranging from pH 3.5 to 7.2.

Conflicts

  • Anionic surfactants (unless specific formulation for compatibility is achieved)
  • Strongly concentrated acids
  • Strongly concentrated bases
  • Small non-polar solvents (e.g., fuels, paint thinners)

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

No direct safety assessment by CIR (Cosmetic Ingredient Review) or SCCS (Scientific Committee on Consumer Safety) specifically for SILICONE QUATERNIUM-1 has been published. However, general silicones are widely regarded as nontoxic, noncarcinogenic, and hypoallergenic. A CIR report on related dimethicone, methicone, and substituted siloxane ingredients concluded their safety in cosmetics due to unlikely skin absorption. Environmental concerns noted by the European Union Ecolabel program include persistence, lack of anaerobic degradability, and moderate acute aquatic toxicity.
