Abstract

Abstract An antiperspirant composition is disclosed suitable for application by a pump spray, a pressurized aerosol or a roll-on. The composition comprises an active antiperspirant salt; a hydrophobic suspending agent; and as a liquid carrier, the benzoic acid esters of a mixture of linear primary alcohols in the C9 to C15 carbon chain length. When the said composition is maintained in a pressurized spray container, a liquified normally gaseous propellant is also present. Quantities of additional components may also be present in the composition including ethanol, or other polar solvent such as a fatty acid ester, and a volatile silicone. The said composition exhibits very slow settling times, fast onset of efficacy, and the cited carrier is virtually odor-free.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 81 words
In an antipersipirant composition comprising an active antiperspirant salt, a particular suspending agent, and a liquid carrier, the improvement comprising wherein said liquid carrier comprises the benzoic acid esters of a mixture of linear primary alcohols in the C 9 to C 15 carbon chain length range, said esters enabling increased suspension time and softer packing of settled matter following agitation of said composition, and a reduction in odor and in oily sensation when said composition is deposited upon the skin.
Claim 2
Dependent Claim 81 words
In an antipersipirant composition comprising an active antiperspirant salt, a particular suspending agent, and a liquid carrier, the improvement comprising wherein said liquid carrier comprises the benzoic acid esters of a mixture of linear primary alcohols in the C 9 to C 15 carbon chain length range, said esters enabling increased suspension time and softer packing of settled matter following agitation of said composition, and a reduction in odor and in oily sensation when said composition is deposited upon the skin.
Claim 3
Dependent Claim 21 words
A composition in accordance with claim 1, wherein said composition is maintained in a pressurized spray container, together with a propellant.
Claim 4
Dependent Claim 30 words
A composition in accordance with claim 1, wherein salt comprises from about 5 to 40 percent by weight thereof, and said carrier comprises 30 to 90 percent by weight thereof.
Claim 5
Dependent Claim 22 words
A composition in accordance with claim 3, wherein said suspending agent comprises from about 0.1 to 10% by weight of said composition.
Claim 6
Dependent Claim 25 words
A composition in accordance with claim 2, wherein said propellant comprises from about 40 to 90 percent by weight of the contents of said container.
Claim 7
Dependent Claim 90 words
In an antiperspirant composition comprising an active antiperspirant salt, a particulate suspending agent, and a liquid carrier, the improvement comprising wherein said liquid carrier comprises a mixture of (a) the benzoic acid esters of a mixture of linear primary alcohols in the C 9 to C 15 carbon chain length range with (b) a volatile silicone, said esters enabling increased suspension time and softer packing of settled matter following agitation of said composition, and a reduction in odor and in oily sensation when said composition is deposited upon the skin.
Claim 8
Dependent Claim 90 words
In an antiperspirant composition comprising an active antiperspirant salt, a particulate suspending agent, and a liquid carrier, the improvement comprising wherein said liquid carrier comprises a mixture of (a) the benzoic acid esters of a mixture of linear primary alcohols in the C 9 to C 15 carbon chain length range with (b) a volatile silicone, said esters enabling increased suspension time and softer packing of settled matter following agitation of said composition, and a reduction in odor and in oily sensation when said composition is deposited upon the skin.
Claim 9
Dependent Claim 14 words

Claim 10
Dependent Claim 28 words
A composition in accordance with claim 6, wherein the ratio between said benzoic acid esters and said silicone is in the range of from about 99:1 to 1:99.
Claim 11
Dependent Claim 35 words
A composition in accordance with claim 6, wherein said salt comprises from about 5 to 40 percent by weight of said composition, and said carrier comprises from about 50 to 80 percent by weight thereof.

Dependent Claim 35 words
A composition in accordance with claim 6, wherein said composition is maintained in a pressurized container; together with a propellant; said propellant comprising 40 to 90 percent by weight of the contents of said container.
Claim 13
Dependent Claim 32 words
A composition in accordance with claim 1, wherein said benzoic acid esters are those of a mixture of linear primary alcohols in the C 12 to C 15 carbon chain length range.
Claim 14
Dependent Claim 32 words
A composition in accordance with claim 6, wherein said benzoic acid esters are those of a mixture of linear primary alcohols in the C 12 to C 15 carbon chain length range.
