Science
Mechanism of Action
On the skin, PPG-33-Buteth-45 acts as a conditioning agent, reducing flaking and restoring suppleness by forming a protective film. For hair, it improves body, sheen, and texture by lubricating and smoothing the hair shaft. As a liquid polypropylene glycol derivative, it further contributes to formulation by dissolving other ingredients (solvent) and ensuring their even distribution (solubilizer).

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded PPG-33-Buteth-45 is safe when formulated to be non-irritating. While some clinical tests on related compounds did not show significant irritation, general toxicity data suggests a potential for irritation, necessitating precise formulation to avoid adverse reactions. The U.S. FDA participated in this CIR evaluation. No specific maximum concentration is universally set, with safety contingent upon proper non-irritating formulation.
