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
