Abstract

Et mikronisert plantepulver impregneres med to separate opplosnlnger (A) og (B) slik at de to oppløsninger fullstendig absorberes av pulveret som derfor forblir l form av et fast pulver. Oppløsning (A) består av en vandig hydrogenperoksyd- oppløsnlng, mens oppløsning (8) består av en basisk, vandig oppløsning Inneholdende et alkalisk middel.A micronized plant powder is impregnated with two separate solutions (A) and (B) so that the two solutions are completely absorbed by the powder, which therefore remains in the form of a solid powder. Solution (A) consists of an aqueous hydrogen peroxide solution, while solution (8) consists of a basic aqueous solution containing an alkaline agent.
