Patent number: 6096297Abstract: An underarm composition is provided which includes C.sub.1 -C.sub.6 alkyl acetate, an underarm active selected from astringent salts and anti-microbial agents, and a carrier. The carrier may include propellant, silicone, ester and liquid paraffin. Methyl and t-butyl acetates are preferred. Acetates allow reduction in the levels of more volatile organics thereby decreasing air pollution. They also reduce formulation greasiness, are less clogging to spray nozzles, cause less metal can corrosion and reduce caking of actives through better resuspension.Type: GrantFiled: January 12, 1999Date of Patent: August 1, 2000Assignee: Unilever Home & Personal Care USAInventors: Francis Jones, David Allen Brewster

Patent number: 6086860Abstract: An antiperspirant aerosol spray product is provided packaged in a metal can. Within the can is an antiperspirant aerosol spray composition that includes a propellant, a C.sub.1 -C.sub.3 alcohol and an antiperspirant aluminum astringent salt having a water loss under drying no greater than about 8%. Corrosion and malodor can be minimized by use of low water containing antiperspirant astringent salts even in the presence of very substantial amounts of alcohol which normally tends to accelerate the corrosion process.Type: GrantFiled: April 6, 1999Date of Patent: July 11, 2000Assignee: Chesebrough-Pond's USA Co., divsion of Conopco, Inc.Inventor: David Allen Brewster
