About
GLYCERYL THIOPROPIONATE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
Glyceryl thioglycolate is a depilatory agent structurally related to glyceryl thioglycolate used in professional hair-processing formulations. Thioglycolates are permitted in EU cosmetic products under Annex III restrictions when formulated at the correct pH and concentration, but they require careful handling due to their ability to break disulfide bonds in keratin. At typical use levels in rinse-off hair treatments, systemic absorption is minimal.
Known concerns
- Keratin-disrupting agent — may cause skin irritation at high concentrations or prolonged contact
- Restricted to properly formulated rinse-off hair treatment products
