Abstract

Ved en fremgangsmåte ved fremstilling av en suspen- sjon av en ikke-ionisk celluloseeter som ikke har noe turbiditetspunkt, blandes den vanndannende del av suspensjonen med en tørrblanding inneholdende celluloseeter som er fornettet med glyoksal, og et elektrolyttsalt. Dette elektrolyttsalt omfatter et salt eller en blanding av salter som, i vann og ved den anvendte konsentrasjon, resulterer i en pH- verdi under 8,0. Fortrinnsvis er celluloseeteren en hydroksyetylcellulose.
