PEG-8
PEG-8 is a smallish polymer molecule created from repeated units of polyethylene glycol (PEG). It is a clear, colorless, water-soluble liquid that functions primarily as a solubilizer and viscosity control agent. It can help solubilize sparingly water-soluble ingredients (e.g., vanilla, perfumes) into water-based formulas.

humectant● Benefits
PEG-8 is water-binding (humectant) and helps prevent the drying out of formulas, especially when combined with other hygroscopic agents such as sorbitol. Its solubilizing properties allow it to incorporate difficult-to-dissolve ingredients into aqueous systems.
