Abstract
Gelled or solid topically-effective compositions comprising a topically-active compound, like an antiperspirant compound; a borate crosslinker; a surfactant, and preferably, a nonionic surfactant or nonionic surfactant blend; a carrier comprising water; and, optionally, a hydrophobic compound, are disclosed.
Claims30
A gelled or solid antiperspirant composition comprising:
- (a) about 1% to about 40% by weight of an antiperspirant compound;
- (b) about 0.5% to 10% by weight of a borate crosslinker;
- (c) about 0.5% to about 70% by weight of a surfactant selected from the group consisting of a nonionic surfactant or a nonionic surfactant blend, wherein the nonionic surfactant and nonionic surfactant blend has an HLB value of about 3 to about 20;
- and
- (d) a carrier comprising water;
- wherein the antiperspirant composition has a pH of about 3 to about 5, a penetrometer reading of about 4 mm to about 10 mm, and a % transmittance at 700 nm of at least 50%.
A gelled or solid antiperspirant composition comprising:
- (a) about 5% to about 30% by weight of an aluminum halide, an aluminum hydroxyhalide, a zirconyl oxyhalide, a zirconyl hydroxyhalide, an aluminum zirconium glycinate, or a mixture thereof;
- (b) about 0.8% to about 7% by weight of boric acid, sodium tetraborate, or a mixture thereof;
- (c) about 1% to about 50% by weight of a nonionic surfactant blend comprising:
- (i) a first nonionic surfactant having an HLB value of about 10 or greater, and (ii) a second nonionic surfactant having an HLB of less than about 10, wherein a sufficient amount of the first nonionic surfactant is blended with a sufficient amount of the second nonionic surfactant to provide the nonionic surfactant blend having the HLB value of about 10 to about 15;
- and
- (d) an aqueous-based carrier,
- wherein the antiperspirant composition has a pH of about 3 to about 5.
A method of treating or preventing malodors associated with human perspiration comprising topically applying an effective amount of an antiperspirant composition to human skin, said composition comprising:
- (a) about 1% to about 40% by weight of an antiperspirant compound;
- (b) about 0.5% to about 70% by weight of a surfactant selected from the group consisting of a nonionic surfactant or a nonionic surfactant blend, wherein the nonionic surfactant or nonionic surfactant blend has an HLB value of about 3 to about 20;
- and
- (d) a carrier comprising water,
- wherein the antiperspirant composition has a pH of about 3 to about 5, a penetrometer reading of about 4 mm to about 10 mm, and a % transmittance at 700 nm of at least 50%.
A gelled or solid antiperspirant composition comprising:
- (a) about 1% to about 40% by weight of an antiperspirant compound;
- (b) about 0.5% to about 10% by weight of a borate crosslinker;
- (c) about 0.5% to about 70% by weight of a nonionic surfactant blend comprising:
- (i) a first nonionic surfactant having an HLB value of about 10 or greater, and (ii) a second nonionic surfactant having an HLB of less than about 10, wherein a sufficient amount of the first nonionic surfactant is blended with a sufficient amount of the second nonionic surfactant to provide the nonionic surfactant blend having the HLB value of about 10 to about 15;
- and
- (d) a carrier comprising water;
- wherein the antiperspirant composition has a pH of about 3 to about 5.
A method of treating or preventing malodors associated with human perspiration comprising topically applying an effective amount of an antiperspirant composition to human skin, said composition comprising:
- (a) about 1% to about 40% by weight of an antiperspirant compound;
- (b) about 0.5% to about 10% by weight of a borate crosslinker;
- (c) about 0.5% to about 70% by weight of a nonionic surfactant blend comprising:
- (i) a first nonionic surfactant having an HLB value of about 10 or greater, and (ii) a second nonionic surfactant having an HLB of less than about 10, wherein a sufficient amount of the first nonionic surfactant is blended with a sufficient amount of the second nonionic surfactant to provide the nonionic surfactant blend having the HLB value of about 10 to about 15;
- and
- (d) a carrier comprising water,
- wherein the antiperspirant composition has a pH of about 3 to about 5.
