摘要：
A stabilizing composition comprising: a. a microcrystalline cellulose； and b. a water soluble carboxymethyl cellulose selected from: i) a low viscosity water soluble carboxymethyl cellulose having a Brookfield viscosity from 10 to 200 cps measured in a 2.6% dispersion in deionized water using an RTV viscometer at 20 rpm at 20 ° C- 23 ° C, in which the weight ratio of microcrystalline cellulose and carboxymethyl cellulose is from 95: 5 to 70:30； and ii) a water-soluble carboxymethyl cellulose with medium viscosity having a Brookfield viscosity of 200 to 4000 cps measured at a 2.6% dispersion in deionized water using an RTV viscometer at 20 rpm at 20 ° C-23 ° C in which the The weight ratio of microcrystalline cellulose and carboxymethyl cellulose is from 95: 5 to 70:30； characterized in that said water-soluble carboxymethylcellulose has a degree of substitution from 0.45 to 0.85, the stabilizing composition is produced by co-reducing a mixture of said microcrystalline cellulose in the form of a wet cake having at least 42% solids with said water soluble carboxymethyl cellulose, and when the stabilizing composition includes water soluble carboxymethyl cellulose of low viscosity, after dispersion in water at 2.6% solids, the stabilizing composition has an initial viscosity of at least 750 cps, an adjusted viscosity of at least 2900 cps, and an adjusted gel resistance G 'of at least 20 Pa, and when the stabilizing composition includes the water soluble carboxymethylcellulose of medium viscosity, after dispersion in water at 2.6% solids, the stabilizing composition has an initial viscosity of at least 1000 cps, an adjusted viscosity of at least 3500 cps, and a resistance ia to the adjusted gel G 'of at least 40 Pa.Una composición estabilizadora que comprende: a. una celulosa microcristalina； y b. una carboximetilcelulosa soluble en agua seleccionada de: i) una carboximetilcelulosa soluble en agua de baja viscosidad que tiene una viscosidad Brookfield desde 10 hasta 200 c
