The Formula
Formulation
Stability
The substance is generally stable, requiring storage at room temperature in a tightly closed container, protected from direct sunlight, heat, and moisture.
Conflicts
- Strong oxidants (in solid form, due to potential for combustion)
- Ingredients capable of forming N-nitroso compounds (a general precaution for certain quaternary ammonium salts)
Safety
Safety Profile
While not directly reviewed by the Cosmetic Ingredient Review (CIR), this quaternary ammonium salt is related to similar compounds, such as Quaternium-26, which have been deemed safe with the restriction that they should not be used where N-nitroso compounds may form. The EPA Safer Chemical program categorizes it as 'Green circle', indicating low concern. However, the Environmental Working Group (EWG) assigns a 'Moderate' hazard score, highlighting low-to-moderate concerns for skin allergies and immunotoxicity, and low concerns for neurotoxicity and developmental/reproductive toxicity. The EU Ecolabel also reports high acute toxicity to aquatic life.
