A method for reducing perspiration comprising the application to the surface of the human body of M(i)Al(SO4)2 or Al2(SO4)3 and CaX2 wherein M(i) is K+, Na+, NH4+ or mixture thereof, and X is Cl−, Br−, I−, NO3− or mixture thereof.
An antiperspirant product comprising a cosmetically acceptable liquid carrier material, a first salt that is M(i)Al(SO4)2 or Al2(SO4)3 and a second salt that is CaX2, wherein X is Cl−, Br−, I−, NO3− or mixture thereof, characterised in that the first salt and the second salt are formulated or contained in a manner that prevents physical interaction between these two components prior to their application.
A method of manufacture of an antiperspirant composition comprising the bringing together an alum salt and calcium chloride, characterised in that the alum salt is reduced in water content prior to combining with the calcium chloride in a carrier material.
