Safety score · 0–100

Moderate

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

A small cationic conditioning salt derived from allylamine and succinic acid. Used in hair-care to reduce static, but limited safety data and the reactive allyl group raise reasonable caution.

Skin benefits

  • Cationic-flavored quaternary salt that can offer film-forming or conditioning behavior
  • Succinate counter-ion is mild and biocompatible
  • Used in rinse-off formulations at low percentages
  • Provides anti-static properties on hair surfaces

Known concerns

  • Allyl-containing amines are flagged for reactivity and potential sensitization
  • No CIR or SCCS safety assessment identified for this specific salt
  • Residual monomer concerns common to allylamine chemistry
  • Limited transparency on grade and impurity profile
