Abstract
Abstract A stable antiperspirant emulsion is disclosed which contains an antiperspirant salt of aluminum and/or zirconium, volatile cyclic silicone, water, and a low pH-stable emulsifier mixture of polyethylene glycol (21) stearyl ether and a lipophilic co-emulsifier such that the HLB of the emulsifier mixture is more than 7.5 and less than 9.9.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
100 words
A stable antiperspirant emulsion consisting essentially of: (a) from about 5% to about 25% of an antiperspirant salt of aluminum or zirconium or combinations thereof, (b) from about 15% to about 25% of a volatile cyclic silicone, (c) from about 2% to about 10% of a low pH-stable emulsifier mixture which comprises polyethylene glycol (21) stearyl ether and a lipophilic co-emulsifier such that the HLB of the emulsifier mixture is more than 7.5 and less than 9.9, and (d) from about 35% to about 78% of water, said percentages being by weight based on the total weight of the composition.
Claim 2
Dependent Claim
100 words
A stable antiperspirant emulsion consisting essentially of: (a) from about 5% to about 25% of an antiperspirant salt of aluminum or zirconium or combinations thereof, (b) from about 15% to about 25% of a volatile cyclic silicone, (c) from about 2% to about 10% of a low pH-stable emulsifier mixture which comprises polyethylene glycol (21) stearyl ether and a lipophilic co-emulsifier such that the HLB of the emulsifier mixture is more than 7.5 and less than 9.9, and (d) from about 35% to about 78% of water, said percentages being by weight based on the total weight of the composition.
