Abstract
Abstract Antiperspirant compositions containing an aqueous solution of an astringent compound as a discontinuous or dispersed phase in a solid matrix of a volatile silicone, a solid alkanol containing at least 12 carbon atoms, a C4 to C8 alkylene diol, and a saturated C12 to C20 fatty acid ester of at least one polyglycerol emulsifying agent having a resultant HLB value of 6 to 9. The compositions may also contain an alkanoic acid having at least 12 carbon atoms.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
An antiperspirant stick composition consisting essentially of: (a) 10 to 70 parts by weight of an aqueous solution of an astringent metal compound as a discontinuous phase dispersed in a solid matrix consisting essentially of (b) 0.1 to 35 parts by weight of a volatile cyclic dimethylsiloxane liquid, (c) 10 to 30 parts by weight of at least one solid alkanol containing at least 12 carbon atoms, (d) 1 to 5 parts by weight of a C.sub. 4 to C.sub. 8 alkanediol, and (e) 0.5 to 5 parts by weight of at least one C.sub. 12 to C.sub. 20 fatty acid ester of a polyglycerol, said ester having a resultant HLB value of 6 to 9; the total of (a) through (e) being 100 parts by weight.
Claim 2
Dependent Claim
127 words
An antiperspirant stick composition consisting essentially of: (a) 10 to 70 parts by weight of an aqueous solution of an astringent metal compound as a discontinuous phase dispersed in a solid matrix consisting essentially of (b) 0.1 to 35 parts by weight of a volatile cyclic dimethylsiloxane liquid, (c) 10 to 30 parts by weight of at least one solid alkanol containing at least 12 carbon atoms, (d) 1 to 5 parts by weight of a C.sub. 4 to C.sub. 8 alkanediol, and (e) 0.5 to 5 parts by weight of at least one C.sub. 12 to C.sub. 20 fatty acid ester of a polyglycerol, said ester having a resultant HLB value of 6 to 9; the total of (a) through (e) being 100 parts by weight.
