Abstract
An antiperspirant aerosol composition has a level of volatile organic compounds no greater than 60 wt. %. The composition includes particulate antiperspirant material and optionally particulate filler material. The filler material may be chemically modified corn starch, micronized polyethylene, cross-linked polyurethanes, polyacrylates, talc, sodium bicarbonate, corn starch, or any combination thereof. The antiperspirant aerosol compositions includes 10-35 wt. % of particulate material, 0.2-2 wt. % of a suspending agent, 5-50 wt. % of emollient carrier liquids and no more than 60 wt. % of an aerosol propellant mixture. The particulate material consists of 25 to 100 wt. % of a particulate antiperspirant active material and 0 to 75 wt. % of a particulate filler material. In addition, the antiperspirant aerosol compositions may contain certain optional components, such as activators, germicides, medicants, perfumes and colorants.
