Abstract

En un método para producir una suspension de éter de celulosa no ionico que no tiene punto de turbidez, el agua forma parte de la suspension es mezclada seca conteniendo un éter de celulosa, el cual es reticulado con glioxal, y una sal electrolítica. Esta sal electrolítica. Esta sal electrolítica consiste de una sal o mezcla de sales las cuales, en agua y a una concentracion empleada, resultan en un valor de pH abajo de 8.0. De preferencia, el éter de celulosa es una hidroxietilcelulosa.
