A new use of hydrophobic zeolites, viz. for removing preservatives from (poly)peptide solutions, e.g. solutions of pharmaceutical preparations. The use is of particular interest in connection with protein solutions, especially insulin solutions. The invention further relates to an injection syringe for such solutions, in which syringe a zeolite of the type at issue is placed for contact with the solution to remove preservatives therefrom.
