AEROSIL® fumed silica for antiperspirants
AEROSIL® and SIPERNAT® silica fulfils a wide range of functions in antiperspirant sprays, roll-ons and sticks.
As an effective suspension stabilizer AEROSIL® products prevent the agglomeration of active ingredients—generally aluminium and zirconium salts (AP salts)—helping to ensure that they are evenly distributed and have an intense and long-lasting effect.
AEROSIL® and SIPERNAT® silica can also increase the viscosity of deodorant roll-ons and sticks. In aerosol sprays, silica prevents suspended active ingredients from setting and the spray nozzle from clogging. Another advantage over other suspending agents is that AEROSIL® fumed silica can increase the transparency of deodorants.
Particularly on dark clothing, antiperspirants often leave a fine, white residue. The use of silica significantly reduces this problem. It is also not necessary to add iron scanvengers and whitening agents to antiperspirant sticks made with silica.
