KLEPTOSE® HP Biopharma Low endotoxin Hydroxypropyl β-cyclodextrin

128446-35-5

White or almost white amorphous powder.
The statistical hydroxypropylation of beta-cyclodextrin creates a multitude of molecules, differing by the position of the hydroxypropyl groups. Consequently, the product is not able to crystallize and remains in the amorphous state.

KLEPTOSE® HP for biopharma uses. It is a low endotoxin pyrogen-free solution for protein stabilization. It exhibits surface activity and anti-aggregation properties for therapeutic proteins shelf life extension. KLEPTOSE® HP Biopharma also enables to reduce thermal and agitation sensitivity of formulations.
