Abstract

A spreading material is described which comprises a porous flat-shaped structure impregnated with a wetting agent, wherein the wetting agent is, an N-acyl-N-alkylglycinate of formula I

R-CO-N(R1)-CH2-COOMe (I) in which R denotes an aliphatic residue with 9 to 23 C
atoms, in particular with 11 to 17 C atoms, which is saturated and has one to three double bonds, R1 denotes hydrogen or lower alkyl and Me is hydrogen or a metal atom, the production of this spreading material as well as diagnostic test strips which contain this spreading material.
