Antiperspirant compositions
View Patent ↗An antiperspirant composition may include an aqueous carrier; and at least 4 to 7 weight percent of an aluminum and/or aluminum-zirconium antiperspirant active containing at least a Peak 4 specie. An antiperspirant composition may also include an aqueous carrier; and an aluminum and/or aluminum-zirconium antiperspirant active containing at least a Peak 4 specie, wherein the antiperspirant active contains less than 3 area percent Peak 1 and/or Peak 2 species from an HPLC chromatograph of the antiperspirant composition.
1. An antiperspirant composition, comprising:
an aqueous carrier comprising water; and
a solution of antiperspirant active that provides an aluminum and/or aluminum-zirconium antiperspirant active;
wherein the antiperspirant composition includes about 60 to 95 percent aqueous carrier including about 58 to 78 percent water, 5 to 7 weight percent antiperspirant active and at least a Peak 4 specie, wherein from an HPLC chromatograph of the antiperspirant composition, the antiperspirant active contains an area for the Peak 4 species that is at least twice an area for Peak 1 and 2 species.
2. The antiperspirant composition of claim 1 , wherein the aluminum and/or aluminum-zirconium antiperspirant active is present in an amount ranging from at least 5.7 to 6.3 weight percent of the antiperspirant composition.
3. The antiperspirant composition of claim 1 , wherein the antiperspirant active comprises less than 5 area percent Peak 1 and/or Peak 2 species from an HPLC chromatograph of the antiperspirant composition.
4. The antiperspirant composition of claim 3 , wherein the antiperspirant active contains less than 2 area percent Peak 1 and/or Peak 2 species from an HPLC chromatograph of the antiperspirant composition.
5. The antiperspirant composition of claim 4 , wherein the antiperspirant active contains substantially no Peak 1 and/or Peak 2 species from an HPLC chromatograph of the antiperspirant composition.
6. The antiperspirant composition of claim 1 , further comprising at least one of nonionic, cationic, or anionic surfactants, wash-off aids, deodorant actives, fragrances, chelating agents, residue masking agents, skin active agents, moisturizers, emollients, inert solids, thickeners, propellant, preservatives, processing aids, dyes, suspending agents, conditioning agents.
7. The antiperspirant composition of claim 1 , wherein the aqueous carrier is present in an amount ranging from about 75 to 95 weight percent of the composition.
8. The antiperspirant composition of claim 7 , wherein the aqueous carrier is present in an amount ranging from about 85 to 95 weight percent of the composition.
9. The antiperspirant composition of claim 1 , wherein the antiperspirant active is selected from aluminum-zirconium octachlorohydrex, aluminum chlorohydrate, and combinations thereof.
10. The antiperspirant composition of claim 1 , wherein the aluminum and/or aluminum-zirconium antiperspirant active is an aluminum and/or aluminum-zirconium halide, hydroxyhalide, and/or oxyhalide antiperspirant active.
11. The antiperspirant composition of claim 1 , wherein the aluminum and/or aluminum-zirconium antiperspirant active is an aluminum and/or aluminum-zirconium chloride, hydroxychloride, and/or oxychloride antiperspirant active.
