The hydrophilic surfactant can be present in an amount sufficient to minimize perspiration-induced discoloration of fabric in contact with the composition. The fatty alcohol and the antiperspirant active agent can be present at a weight ratio of from about 2:1 to about 1:2. ## Claims ### Claim 1 An antiperspirant stick composition, comprising: 1.5 wt % to 2.0 wt % of a synthetic wax; 16 wt % to 22 wt % of a fatty alcohol; 2 wt % to 10 wt % a hydrophilic surfactant having a hydrophilic-lipophilic balance (HLB) value greater than 10, said hydrophilic surfactant being present in an amount sufficient to minimize perspiration-induced discoloration of fabric in contact with the composition; 0.5 wt % to 5 wt % of the plasticizer propylene carbonate; and 14 wt % to about 20 wt % of an antiperspirant active agent, wherein the fatty alcohol and the antiperspirant active agent are present at a weight ratio of from 2:1 to 1:2, wherein the composition includes less than 2 wt % polyethylenes having a melting point greater than or equal to 60° C. ### Claim 2 (depends on 1) The composition of claim 1, wherein the synthetic wax has a weight average molecular weight (Mw) of from 100 g/mol to 2000 g/mol. ### Claim 3 (depends on 1) The composition of claim 1, wherein the synthetic wax has a melting point less than or equal to about 90° C. ### Claim 4 (depends on 1) The composition of claim 1, wherein the synthetic wax has a viscosity of from about 0.1 centipoise (cps) to about 20 cps at a temperature of 99° C. ### Claim 5 (depends on 1) The composition of claim 1, wherein the synthetic wax has a penetration value of from about 8 decimillimeters (dmm) to about 30 dmm at 25° C. ### Claim 6 (depends on 1) The composition of claim 1, wherein the fatty alcohol comprises a saturated or unsaturated C8-C26 fatty alcohol. ### Claim 7 (depends on 1) The composition of claim 1, wherein the fatty alcohol comprises lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, arachidyl alcohol, behenyl alcohol, or a combination thereof. ### Claim 8 (depends on 1) The composition of claim 1, wherein the hydrophilic surfactant is a non-ionic surfactant. ### Claim 9 (depends on 1) The composition of claim 1, wherein the hydrophilic surfactant has a melting point greater than or equal to 35° C. ### Claim 10 (depends on 1) The composition of claim 1, wherein the hydrophilic surfactant is an ethoxylated surfactant. ### Claim 11 (depends on 1) The composition of claim 1, wherein the hydrophilic surfactant has a molecular formula of R—(OA)n—OH, where R represents a C12-C24 alkyl group, OA represents an ethylene oxide or propylene oxide group, and n represents an integer from 20 to 40. ### Claim 12 (depends on 1) The composition of claim 1, wherein the hydrophilic surfactant and the plasticizer are present at a weight ratio of from 1:1 to 6:1 hydrophilic surfactant to plasticizer. ### Claim 13 (depends on 1) The composition of claim 1, wherein the antiperspirant active agent is a member selected from the group consisting of aluminum chlorohydrate, aluminum chloride, aluminum hydroxide, aluminum chlorohydrex polyethylene glycol, aluminum chlorohydrex propylene glycol, aluminum dichlorohydrate, aluminum dichlorohydrex polyethylene glycol, aluminum dichlorohydrex propylene glycol, aluminum sesquichlorohydrate, aluminum sesquichlorohydrate polyethylene glycol, aluminum sesquichlorohydrate propylene glycol, aluminum-zirconium octachlorohydrate, aluminum-zirconium octachlorohydrex glycine, aluminum-zirconium pentachlorohydrate, aluminum-zirconium pentachlorohydrex glycine; aluminum-zirconium tetrachlorohydrate, aluminum-zirconium tetrachlorohydrex glycine, aluminum-zirconium trichlorohydrate, aluminum-zirconium trichlorohydrex glycine, potassium aluminum sulfate, aluminum undecylenoyl collagen amino acid, sodium aluminum lactate, aluminum sulfate, sodium aluminum chlorohydroxylactate, aluminum bromohydrate, aluminum chlorohydroxyallantoinate, zinc chloride, zinc sulfocarbolate, zinc sulfate, zirconium chlorohydrate, and combinations thereof. ### Claim 14 (depends on 1) The composition of claim 1, further comprising a lubricant. ### Claim 15 (depends on 14) The composition of claim 14, wherein the lubricant is a member selected from the group consisting of cyclopentasiloxane, cyclohexasiloxane, dimethylpolysiloxane, methylphenylpolysiloxane, hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, and combinations thereof.
