Safety score · 0–100

Moderate

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A cationic polymer combining a styrene backbone with a long-chain lauryl quat — used for cleansing and antistatic effects. Carries two purity flags: residual styrene monomer and the harsher lauryl-quat irritation potential.

Function

SOLVENTSURFACTANT - CLEANSING

Skin benefits

  • Cleanses and removes oily debris from skin and hair
  • Antistatic and conditioning surfactant properties
  • Surface-active without typical anionic harshness

Known concerns

  • Quat polymer — known eye irritant at higher %
  • Styrene-derived backbone: residual styrene monomer concern (IARC 2A) if poorly stripped
  • Lauryl-quat moiety is a stronger irritant than smaller polyquats
  • Limited public toxicology
