PEG-5 Isononanoate
What is PEG-5 Isononanoate?
PEG-5 Isononanoate is a synthetic polyethylene glycol ester derived from isononanoic acid and a chain of five ethylene oxide units. This clear, low-viscosity liquid belongs to the class of PEG fatty acid esters commonly used in cosmetics. It functions primarily as an emollient in skincare, haircare, and makeup products, where it forms a thin, non-greasy film on the skin to promote smoothness and reduce the appearance of dryness. As a surfactant-emulsifying agent, it stabilizes formulations by blending water and oil phases effectively. It also acts as a solubilizer, allowing better dispersion of fragrances and oils in aqueous systems. Typically found in lotions, conditioners, shampoos, and cleansers, it improves product spreadability, slip, and overall sensory experience without heavy residue.
