Expert Verdict

The aminopropyl group can raise pH locally and may cause scalp sensitivity at high concentrations; silicone and PEG backbone assessed as safe; 1,4-dioxane trace concern applies. Aminofunctional silicone with PEG/PPG modification; the amino group provides substantivity (electrostatic binding to damaged, negatively-charged hair); the PEG/PPG chain ensures water dispersibility, reducing buildup vs. traditional amodimethicone
