About

A quaternary ammonium-type surfactant with limited published safety data, warranting caution in cosmetic formulations.

This is a cationic surfactant derived from isoquinoline with a saccharinate counterion. There is no specific entry in EU Annexes II or III for this ingredient, and published toxicological data are sparse. Quaternary ammonium compounds may cause irritation in sensitive individuals and their safety in cosmetic use depends heavily on the free isoquinoline content.

Skin benefits
