About

A cholinergic salt with irritant properties and potential systemic effects if absorbed through skin.

Acetylcholine iodide is a quaternary ammonium salt of the neurotransmitter acetylcholine, showing irritant properties (H315, H319, H335) and acute oral toxicity (H302). While acetylcholine itself is an endogenous compound, its iodide salt carries the typical hazards of iodide exposure including potential thyroid effects. It is not listed among approved cosmetic ingredients in the EU.
