Poloxamer 407, marketed as Synperonic PE/F 127 by Croda, is one of the most sophisticated multifunctional ingredients available to cosmetic and pharmaceutical formulators. A nonionic block copolymer with a uniquely amphiphilic structure, it bridges the gap between oil and water with remarkable efficiency — stabilizing emulsions, solubilizing actives, and forming beautifully clear gels that feel smooth and elegant on the skin.
What sets Poloxamer 407 apart is its versatility. At low concentrations it acts as a solubilizer and emulsifier; at higher concentrations it transforms into a structured, thermoreversible gel — fluid when cold, firm at body temperature. This makes it an indispensable tool for advanced skincare, pharmaceutical, and personal care formulations.

Formulation Tips
Add slowly to the water phase with gentle mixing to avoid excessive foaming. Ideal for clear gel systems where transparency is essential. Combine with co-emulsifiers for enhanced stability in complex emulsions. Works well in mild, skin-friendly formulations and is compatible with a wide range of cosmetic actives and preservatives.
