Antiperspirant/deodorant compositions and methods
An antiperspirant composition comprising at least one antiperspirant or deodorant active and at least one retentive filler, where the active is solubilized in a polar solvent and contained within the at least one retentive filler and a method for treating skin.
1 . An antiperspirant composition comprising at least one antiperspirant or deodorant active and at least one retentive filler, where the active is solubilized in a polar solvent and contained within the at least one retentive filler.
2 . The composition of claim 1 wherein the retentive filler is a lamellar filler.
3 . The composition of claim 2 wherein the lamellar filler is talc or mica.
4 . The composition of claim 1 wherein the retentive filler is a crosspolymer.
5 . The composition of claim 1 wherein the retentive filler is a cellulosic.
6 . The composition of claim 1 wherein the retentive filler is silica or a hydrophobically modified silica.
7 . The composition of claim 1 wherein the polar solvent comprises water.
8 . The composition of claim 7 wherein the polar solvent comprises water and at least one mono-, di-, or polyhydric alcohol.
9 . The composition of claim 4 wherein the crosspolymer is HDI trimethylollactone crosspolymer, allyl methacrylates crosspolymer, or mixtures thereof.
10 . The composition of claim 5 wherein the cellulosic is starch substituted with C 1-10 alkyl or alkoxy groups, alkali or alkaline earth metals, or mixtures thereof.
11 . The composition of claim 10 wherein the cellulosix is sodium carboxymethyl starch.
12 . The composition of claim 1 wherein the active is one or more antiperspirant salts.
13 . The composition of claim 1 wherein the active is one or more deodorant actives.
14 . The composition of claim 1 wherein the active is expressed from the retentive filler when the composition is applied to the axilla.
15 . A method for reducing perspiration and/or perspiration odor comprising applying to the axilla a composition comprising at least one antiperspirant or deodorant active solubilized in at least one polar solvent, and at least one retentive filler, said solubilized active being contained in at least one retentive filler and being expressed therefrom when the composition is applied to the axilla.
16 . The method of claim 15 wherein the active is a deodorant active.
17 . The method of claim 15 wherein the active is an antiperspirant active.
18 . The method of claim 15 wherein the retentive filler is a lamellar filler, crosspolymer, cellulosic, or mixtures thereof.
19 . The method of claim 18 wherein the lamellar filler is talc or mica, the crosspolymer is HDI trimethylol hexyllactone crosspolymer, or allyl methacrylates crosspolymer, and the cellulosic is sodium carboxymethyl starch.
20 . The method of claim 15 wherein the polar solvent comprises water.
