  • Patent number: 5902571
    Abstract: Disclosed are antiperspirant cream compositions which have a penetration force value of from about 20 gram.force to about 500 gram.force, and comprise (a) from about 20% to about 80% by weight of a volatile silicone material; (b) from about 5% to about 35% of a particulate antiperspirant active; and (c) from about 0.1% to about 20% by weight of a gellant material comprising glyceryl tribehenate and other triglycerides wherein at least about 75% of the esterified fatty acid moieties of said other triglycerides have from about 18 to about 36 carbon atoms, and the molar ratio of glyceryl tribehenate to said other triglycerides is from about 20:1 to about 1:1. The compositions preferably further comprise a residue masking material.
    Type: Grant

  • Patent number: 5902570
    Abstract: Disclosed are anhydrous antiperspirant cream compositions that are substantially free of polymeric or inorganic thickening, and have improved product stability and spreading performance. These compositions have a rheology profile characterized by select product hardness (from about 75 gram force to about 500 gram force), delta stress (from about 300 dyne/cm.sup.2 to about 8,000 dyne/cm.sup.2) and static yield stress (at least about 1,000 dyne/cm.sup.2 ) values. The new rheology profile is preferably applied to antiperspirant cream compositions comprising from about 0.1% to about 20 % by weight of a crystalline gellant, from about 10% to about 80% by weight of an anhydrous liquid carrier for the crystalline gellant having a solubility parameter of from about 3 to about 13 and, from about 5 % to about 35% by weight of a particulate antiperspirant active.
