BEHENYL METHACRYLATE/PERFLUOROOCTYLETHYL METHACRYLATE COPOLYMER.

Insufficient Data / FILM FORMING, VISCOSITY CONTROLLING

A high-performance synthetic polymer engineered to create a sophisticated, protective film on the skin's surface. It utilizes specialized perfluorinated side chains to provide simultaneous resistance to both water and oils, ensuring long-lasting formula integrity.

Science

This copolymer functions as a surface modifier by creating a 'Lotus Effect' on the skin. It establishes a breathable, hydrophobic and lipophobic barrier that effectively repels sweat and sebum while preventing trans-epidermal moisture loss and enhancing the smudge-resistance of cosmetic applications.

Key findings

  1. 01 The Cosmetic Ingredient Review (CIR) Expert Panel currently notes a lack of peer-reviewed clinical data regarding the specific skin efficacy of this individual copolymer as of their 2023 assessment.

Transparency

Not commonly dusted

As a functional texture and film-forming agent, it is typically used for its structural properties rather than as a 'hero' active ingredient, making traditional 'dusting' less applicable.


The Formula

Solubility
Neither
Optimal pH 3 – 10
0 7 14

Stability

Highly inert and stable across a broad pH spectrum. It is insoluble in water and standard oils, requiring dispersion via silicones or specific esters to maintain stability.

Synergies

  • Silicones
  • Esters
  • Volatile carriers

Conflicts

  • Highly polar aqueous systems
  • Certain hydrocarbons

Safety

CIR Status

Our Assessment

Insufficient Data

While offering exceptional smudge-resistance and barrier properties, its current safety profile is limited by a lack of data regarding environmental impact and potential impurities.
