Patent number: 6261543Abstract: Antiperspirant emulsions which exhibit excellent phase stability even in the presence of an effective concentration of antiperspirant salts in solution and which are thickened are obtainable by dispersing a hydratable polymer and particularly an amphoteric or cationic modified starch in an aqueous emulsion forming a viscous emulsion, often at an elevated temperature, subjecting the emulsion to high shear, thereby reducing the droplet size of the dispersed oil phase, bringing the emulsion to below 40° C. and introducing the antiperspirant, preferably in aqueous solution. The viscous emulsion subjected to high shear mixing desirably has a Sheer Stress of 10 to 500 Pa. The resultant emulsions show good phase stability even when they contain aluminium/ zirconium antiperspirant salts that promote instability and even at elevated storage temperatures such as at 50° C.Type: GrantFiled: October 12, 1999Date of Patent: July 17, 2001Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Neil Robert Fletcher, Miyuki Kanda, Howard Allen Ketelson, Graham Andrew Turner
