Application | TABULOSE® SC 591 colloidal microcrystalline cellulose is a co-processed product composed of microcrystalline cellulose (MCC) and sodium carboxymethylcellulose (CMC). It hydrates quickly and forms a thixotropic suspension in water, making it an ideal product for both suspensions and reconstitutable suspensions. TABULOSE® SC 591 is used as a secondary stabilizer and suspension agent in semi-solid formulas such as suspensions, emulsions, aerosols, creams, lotions and gels. TABULOSE® SC 591 creates a viscous suspension in water having a viscosity of 39 to 91 mPa.s at 1.2% solid content. |
