An agglomerated cellulose excipient obtainable by a process comprising 1) obtaining a cellulose II crystalline form by a process comprising the following steps: a. immersing hydrocellulose in an aqueous solution of sodium hydroxide in a ratio of 1:10, in an inert atmosphere; b. cooling the solution to a temperature within -10°C and 10°C; c. stirring the solution; d. diluting the cellulose obtained in step c), for obtaining a gel with a concentration of 5% to 10% w/v of cellulose; e. adding from 2.5% to 50% of binder, stirring at a rate of 10,000 rpm to 20,000 rpm for a period of 10-15 min; f. neutralizing the solution from step e) with an organic acid selected from hydrochloric acid, nitric acid, sulfuric acid or mixtures thereof for obtaining a conductivity lower than 20 μS/cm; g. optionally drying the dispersion by spray drying; or h. optionally filtering the dispersion for obtaining a pulp with a solid contents within the range 1% - 60%; i. granulating the product of step g) or step h) by dry or wet granulation; and 2) combining the cellulose of step 1 with a binder selected from talc, magnesium carbonate, amorphous silicon dioxide, bentonite, mica, titanium dioxide, zinc dioxide, kaolin, zinc stearate, chitosan, shellac, methacrylic acid derivatives or mixtures thereof. 1) obtaining a cellulose II crystalline form by a process comprising the following steps: a. immersing hydrocellulose in an aqueous solution of sodium hydroxide in a ratio of 1:10, in an inert atmosphere; b. cooling the solution to a temperature within -10°C and 10°C; c. stirring the solution; d. diluting the cellulose obtained in step c), for obtaining a gel with a concentration of 5% to 10% w/v of cellulose; e. adding from 2.5% to 50% of binder, stirring at a rate of 10,000 rpm to 20,000 rpm for a period of 10-15 min; f. neutralizing the solution from step e) with an organic acid selected from hydrochloric acid, nitric acid, sulfuric acid or mixtures thereof for obtaining a conductivity lower than 20 μS/cm; g. optionally drying the dispersion by spray drying; or h. optionally filtering the dispersion for obtaining a pulp with a solid contents within the range 1% - 60%; i. granulating the product of step g) or step h) by dry or wet granulation; and a. immersing hydrocellulose in an aqueous solution of sodium hydroxide in a ratio of 1:10, in an inert atmosphere; b. cooling the solution to a temperature within -10°C and 10°C; c. stirring the solution; d. diluting the cellulose obtained in step c), for obtaining a gel with a concentration of 5% to 10% w/v of cellulose; e. adding from 2.5% to 50% of binder, stirring at a rate of 10,000 rpm to 20,000 rpm for a period of 10-15 min; f. neutralizing the solution from step e) with an organic acid selected from hydrochloric acid, nitric acid, sulfuric acid or mixtures thereof for obtaining a conductivity lower than 20 μS/cm; g. optionally drying the dispersion by spray drying; or h. optionally filtering the dispersion for obtaining a pulp with a solid contents within the range 1% - 60%; i. granulating the product of step g) or step h) by dry or wet granulation; and 2) combining the cellulose of step 1 with a binder selected from talc, magnesium carbonate, amorphous silicon dioxide, bentonite, mica, titanium dioxide, zinc dioxide, kaolin, zinc stearate, chitosan, shellac, methacrylic acid derivatives or mixtures thereof.
