What Is PPG-1 Trideceth-6?
PPG-1 Trideceth-6 is a synthetic polymer derived from propylene glycol and a fatty alcohol derivative. It functions as both a skin conditioner and a mild surfactant, meaning it can help bind water to the skin whilst also improving the texture and spreadability of formulations.
This ingredient is used sparingly in skincare products (found in roughly 0.3% of formulations) and typically appears in lower concentrations within multi-ingredient systems rather than as a standalone active.
How It Works
PPG-1 Trideceth-6 works as a humectant by forming hydrogen bonds with water molecules, drawing them toward the stratum corneum (the skin's outer layer) and slowing water loss. Its mild surfactant properties also allow it to improve how other ingredients blend with the skin's natural oils, creating a more uniform feel.
Clinical Evidence & References
Published clinical research specifically examining PPG-1 Trideceth-6 in isolation is limited. Its safety and efficacy profile are supported primarily by regulatory approval and decades of use in cosmetic formulations at low concentrations. It is generally recognised as a mild, non-irritating ingredient in skincare.
Most benefits associated with this ingredient come from its established chemical properties rather than dedicated clinical studies in human subjects.
How to Use
Since this ingredient is typically present at very low levels within formulations, no special usage instructions are required. It works best as part of a balanced formula; if you are using a product containing it, apply as directed by the brand and layer with other hydrating or active ingredients as needed for your skin's needs.
