Di-PPG-3 Myristyl Ether Adipate

Di-PPG-3 Myristyl Ether Adipate is a synthetic emollient/skin-conditioning ester used to improve slip and reduce tackiness, typically included at low-to-moderate percentages in creams and sunscreens. Available patch-test and safety assessments for similar polypropylene glycol ether adipate esters indicate low irritation potential and minimal sensitization risk, as they are non-volatile and not acid/alkali pH-dependent. In highly reactive or eczematous skin, any leave-on lipid can rarely sting on compromised barriers, but overall this ingredient is very gentle at typical use levels. Safety Notes: Di-PPG-3 Myristyl Ether Adipate is used primarily as a lightweight emollient/slip agent and texture modifier in leave-on products (lotions, creams, primers, sunscreens) and less commonly in rinse-off formats; at the low end it appears around 0.1–1% for sensory enhancement and spreadability in complex emulsions. In real-world OTC “silicone-free” sensory-optimized moisturizers/primers and some balm-like makeup-skin hybrids, it can function as a primary emollient phase component, reaching ~15–25% while remaining cosmetically elegant and stable. There are no specific EU/FDA concentration limits for this ingredient beyond general cosmetic safety and good manufacturing practice, so the practical upper end is driven by sensory targets and emulsion/oil-phase balance rather than regulation.
