ABSTRACT:
The present invention embraces an aerosol antiperspirant composition which comprises a suspension of about 5 to 15% high efficacy aluminum salt in powder form in about 15 to 35% volatile silicone and about 40 to 80% liquefied hydrocarbon propellant with about 0.7 to 1.5% hydrophobic colloidal silica suspending agent and about 0.15 to 0.35% hydrophilic colloidal silica suspending agent. The composition of the present invention has superior antiperspirant efficacy and avoids the use of materials which have an adverse effect on efficacy, namely oil soluble emollient esters such as isopropyl myristate and polar agents such as ethanol.
