PPG-5 Pentaerythrityl Ether (INCI: PPG-5 Pentaerythrityl Ether) is a solvent and co-emulsifier. It dissolves actives and fragrance and helps bind the oil and water phases, which makes even formulas easier. This is a functional ingredient, not a skincare active. Its role is technical: distribution and mixing of the formula. It brings no benefit of its own to the skin. Because of its topical use and lack of systemic relevance, it can be used during pregnancy and breastfeeding without concern. Tolerance is high. Irritation and allergy potential are both low, so it fits sensitive skin. Most skin shows no reaction.
