Verdict

As a secondary amine impurity source, the main risk is formation of nitrosamines (potentially carcinogenic) during manufacture or storage with nitrosating agents. This ingredient functions as a buffer in broader cosmetic categories. EU Annex III conditions are the critical compliance gate.
