Abstract: An improved process for preparing an enhanced antiperspirant active polymeric aluminum compound having the empirical formula:Al.sub.2 (OH).sub.6-a X.sub.a (I)wherein X is Cl, Br, F, I, SO.sub.4 and NO.sub.2, a is about 1.0 to about 4, which is further characterized by (a) a Size Exclusion Chromatograph, (b) a Band III percent aluminum value of at least 40 percent, and preferably (c) a Band I percent aluminum value of not greater than 5 percent, and compositions thereof.
Abstract: This invention relates to solid emollient-moisturizer compositions, and in particular relates to compositions wherein an emollient-moisturizer is entrapped in the lattice of the cross-linked polymer during in situ polymerization of the monomers forming the polymer lattice. The invention provides for conversion of solid and/or liquid emollients or moisturizers into solid, free-flowing forms by entrapment of the functional materials in a hydrophobic polymer lattice.
Abstract: Dry powder antiperspirant compositions consisting essentially of known active antiperspirant chemicals encapsulated and buffered with about 10 to about 45 percent, by weight, of the total composition of a hydrolyzed carbohydrate derived from natural waxy maize; a method of buffering active antiperspirant chemicals during processing to prevent corrosion of the processing equipment; aqueous solutions and gels capable of being dried to form the dry powder antiperspirant compositions; and antiperspirant consumer products formulated from the dry powders, are described.
