Degussa AG of Dusseldorf, Germany, is publishing a new brochure on the use of Aerosil fumed silica in pharmaceuticals. This fine white powder features an array of outstanding properties. In tablets and filled capsules, Aerosil improves the production process, because the flowability of the precursor powder is increased more tablets can be produced in a given time. When incorporated into gels and suppositories, Aerosil also provides for a uniform distribution of the active ingredient and proper consistency during use. This and information about all Aerosil pharmaceutical grades and their regulatory status are available in the brochure, which can be ordered in English at www.aerosil.com.
Aerosil fumed silica is manufactured by means of a high-tech continuous combustion process (flame hydrolysis). By precise adjustment and control of a large number of process parameters, different particle sizes are achieved. The individual product types differ in surface area, given in square meters per gram (standard types range from 90 to 380 m2/g).
