Abstract
Official abstract text for this publication.
An aqueous composition comprising an aluminum sesquichlorohydrate salt, water soluble calcium salt, and amino acid, wherein the molar ratio of water soluble calcium salt to aluminum is at least 1:40 and the molar ratio of amino acid to aluminum is at least 1:20 and methods for making such compositions having enhanced antiperspirancy performance.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aqueous composition comprising an aluminium sesquichlorohydrate salt, water soluble calcium salt, and amino acid, wherein the aluminium sesquichlorohydrate salt is of formula Al 2 (OH) 4.7 Cl 1.3 to Al 2 (OH) 4.9 Cl 1.1 and the molar ratio of calcium to aluminium is from 1:20 to 1:5 and the molar ratio of amino acid to aluminium is from 1:5 to 1:1, wherein the composition is an oil-in-water emulsion comprising an emulsifier, and wherein the emulsion has a continuous phase that is greater than 50% by weight water. 2. The composition according to claim 1 , wherein the water soluble calcium salt is calcium chloride and the amino acid is glycine. 3. The composition according to claim 1 , wherein the aluminium sesquichlorohydrate salt has a Band III content measured by SEC of greater than 40% relative to the total integrated area in all of the regions corresponding to aluminium species. 4. The composition according to claim 1 , wherein the aluminium sesquichlorohydrate salt has a Band III content measured by SEC of greater than 50% relative to the total integrated area in all of regions corresponding to aluminium species. 5. The composition according to claim 1 , wherein molar ratio of calcium to aluminium is from 1:15 to 1:5 and the molar ratio of amino acid to aluminium is from 1:4 to 1:1. 6. The composition according to claim 5 , wherein molar ratio of calcium to aluminium is from 1:10 to 1:5 and the molar ratio of amino acid to aluminium is from 1:3 to 1:1. 7. A method of attaining an antiperspirant benefit comprising the topical application to the surface of the human body of an antiperspirant composition according to claim 1 .
