AEROSIL® colloidal silicon dioxide for liquid dosage forms


AEROSIL® colloidal silicon dioxide may be used as an effective thickener of pharmaceutical media to create soft creams or more viscous gels. Clear gels may be obtained if the refractive index of the media is similar to that of the silica.


AEROSIL® colloidal silicon dioxide can stabilize dispersions of solid substances in water (i.e. redispersible powders and for stabilization of the pigment suspensions employed for tablet coating).
