No specific safety assessment for Quaternium-97 has been conducted by the CIR, SCCS, or FDA. This ingredient belongs to the family of quaternary ammonium compounds (Quats), some of which, like Quaternium-15, are known formaldehyde-releasing preservatives. Such compounds have been linked to potential skin irritation, allergic contact dermatitis, and carcinogenic risks due to formaldehyde release. Quaternium-15, for example, is regulated in the EU with a maximum concentration of 0.2% and requires specific labeling if free formaldehyde levels exceed 0.05%. Moreover, certain U.S. states are implementing bans or restrictions on formaldehyde-releasing preservatives.
