Application


  • Stabilizing Function of P 188 in Dermal Formulations: Examined for its stabilizing effects on industrial concentrates of dermal hesperidin smartCrystals, P 188 contributed to enhancing the long-term stability of the formulations, relevant for dermal therapeutic interventions (Romero et al., 2015).

Biochem/physiol Actions

Poloxamer 188 is widely used as a thickening agent and gel binder.

Other Notes

The Poloxamer 188 grades are poloxamers from the extensive line of block copolymers.
