Science
Mechanism of Action
When in aqueous solution, Potassium Fluorosilicate can liberate fluoride ions and may form hydrofluoric acid. This acid is highly corrosive, reacting aggressively with compounds containing calcium, magnesium, or silicon ions, thereby causing damage to living tissues.

Safety Profile
Potassium Fluorosilicate is categorized as highly toxic and a potent tissue irritant, with potential for fatality if inhaled, swallowed, or absorbed dermally. Direct contact can result in severe irritation, redness, and pain to the skin, eyes, and mucous membranes. Its inclusion in cosmetics is strictly restricted by the EU Cosmetics Directive.
