Safety

May cause irritation or allergic reactions in sensitive areas (e.g., lips, eyes) due to its sensitization potential. Typically used at low levels; some regions set maximum use limits. Discontinue if irritation develops.

Is Propyl Gallate a Good Ingredient?

Fair rating since it chiefly protects the formula’s oils from oxidation rather than delivering clear skin benefits, and it has a recognized sensitization potential. Usefulness is dose-dependent and balanced by the risk of irritation in some users.
