Abstract
An antiperspirant composition comprising a suspension of from 1 to 50% of an aluminium and/or zirconium containing antiperspirant active, a carrier substance in which the antiperspirant active is insoluble, and a poly(ethylene glycol) solution of a polyelectrolyte salt comprising sodium, potassium, magnesium, calcium, chloride and bromide ions, the weight ratio of sodium to the other named cations being less than 3:2 and the weight ratio of the bromide to chloride anion being greater than 1:99, in said solution.

An anhydrous antiperspirant composition comprising a suspension of from 1 to 50% of an aluminium and/or zirconium containing antiperspirant active, a carrier substance in which the antiperspirant active is insoluble, and a poly(ethylene glycol) solution of a polyelectrolyte salt comprising sodium, potassium, magnesium, calcium, chloride and bromide ions, the weight ratio of sodium to the other named cations being less than 3:2, in said solution.
A method of manufacture of an anhydrous antiperspirant composition comprising the dissolution in poly(ethylene glycol) of a polyelectrolyte salt comprising sodium, potassium, magnesium, calcium, chloride and bromide ions, the ratio of sodium to the other named cations in said salt being less than 3:2, the mixing of the so formed poly(ethylene glycol) solution of polyelectrolyte salt into a carrier substance and, before or after said mixing, the introduction of from 1 to 50% of an aluminium and/or zirconium containing antiperspirant active into the carrier substance, the antiperspirant active being insoluble in the carrier substance.
