Abstract: A solid antiperspirant stick composition in the form of a water-in-oil emulsion comprising (i) an aqueous phase comprising dissolved aluminium sesquichlorohydrate antiperspirant active; (ii) an oil phase comprising a solidifying agent; (iii) an emulsifier and (iv) at least 5% by weight of a polyol selected from glycerol, propylene glycol and/or PEG oligomers having a molecular weight of from 180 to 420.

Abstract: An antiperspirant (AP) aerosol product comprising (A) an aerosol composition comprising a volatile propellant and an AP active comprising a basic aluminium chloride compound of formula AI2OH4.4CI1.6 to AI2OH4.9CI1.1, a water-soluble calcium salt and an amino acid, and (B) an aerosol dispenser comprising a container body comprising a chamber for holding the aerosol composition and an aerosol valve, the aerosol valve comprising a housing holding the valve stem and a spring, said aerosol valve being held into the container body by a valve cup internally lacquered with a protective coating, wherein the AP active has a molar ratio of calcium to aluminium of greater than 1:20 and a molar ratio of glycine to aluminium of greater than 1:5.

Abstract: A process for manufacture of an antiperspirant composition comprising the reaction of an aqueous solution of aluminum sesquichlorohydrate, water soluble calcium salt and amino acid, at a total anhydrous solids content of from 33 to 60% by weight and at a temperature of at least 65° C., for a period of from 1 to 24 hours, wherein the molar ratio of water soluble calcium salt to aluminum sesquichlorohydrate is at least 1:40 and the molar ratio of amino acid to aluminum sesquichlorohydrate is at least 1:20, the mixture then being cooled to less than 25° C. and diluted with at least an equal weight of water or to a total anhydrous solids content of less than 31% by weight, the dilution phase being performed within 10 days of cooling phase.
