Tackle odour with this Antiperspirant-Emulsion Stick with AEROSIL® R 974.

The formulation features AEROSIL® R 974 which is a moderately hydrophobic treated fumed silica that is efficient in the thickening and thixotropy of low and non-polar emollients. This ingredient is commonly used in w/o pickering emulsions and also aids in the anti settling of particles in liquid formulations.
