PPG-3 Benzyl Ether Myristate

PPG-3 Benzyl Ether Myristate is primarily an emollient/slip agent used in leave-on products at low-to-moderate concentrations, and it is generally not a primary irritant in standard patch-testing experience. However, as a benzyl ether–containing, lipophilic surfactant-like ester, it can occasionally sting or trigger irritation in compromised barriers (eczema, post-procedure) and may contribute to comedogenic/occlusive discomfort in some patients. Given real-world cumulative exposure in routines and the need to err on patient safety for highly reactive skin, it fits best as a gentle-but-not-inert ingredient. Safety Notes: PPG-3 Benzyl Ether Myristate is used as a lightweight emollient/solvent and slip agent, and in mass-market leave-on lotions, sunscreens, primers, and makeup it is commonly present at low levels (~0.1–2%) to improve spreadability and sensory profile. Higher levels are found in silicone-free anhydrous/low-water oil gels, makeup bases, and specialized “dry oil” style leave-on products where it can function as a primary emollient phase component, reaching ~10–20% in consumer OTC formulations; rinse-off products typically sit toward the lower end because benefits are short contact-time and cost is a constraint.
