Application:
Kolliphor P 188 has been widely used as a thickening agent and gel binder. This research grade product is intended for use in R&D and development only.
Product description:
Poloxamers are ABA-type co-polymers of poly (ethylene oxide) (PEO=A) and poly (propylene oxide) (PPO=B). The approximate relative amount of PEO and the average molecular weight of the PPO are indicated in the name of the poloxamer. For example, P 188 succeeding the word Kolliphor® indicates a poloxamer with ca. 80% m/m PEO (P 188; 8x10= 80%) and approximately average molecular weight of PPO of 1800 (P 188; 18x100= 1800)
Other Notes:
The Kolliphor P grades are poloxamers from the extensive line of Pluronic block copolymers.
