and C13-C15 alkane; about 2 to about 3 percent by weight of ppg-3 benzyl ether myristate; about 0.001 to about 0.01 percent by weight of a sodium laneth 40-maleate/styrene sulfonate copolymer; and about 0.01 to about 0.5 percent by weight of an emollient mixture comprising isostearic acid, sorbitan oleate, cocoyl hydrolyzed keratin and heat to wet hair, thereby removing from about 85% to about 100% of water added to the hair during washing. ## Claims ### Claim 1 A composition comprising: at least about 90 to about 96 percent by weight of a volatile hydrocarbon mixture consisting of C13-C16 isoparaffin, C12-C14 isoparaffin; and C13-C15 alkane, wherein the volatile hydrocarbon mixture exhibits a vapor pressure of more than about 0.2 mm Hg at 25 ° C at one atmosphere of pressure or has a boiling point at one atmosphere of less than about 100° C.; about 2 to about 3 percent by weight of ppg-3 benzyl ether myristate; about 0.001 to about 0.01 percent by weight of a sodium laneth 40-maleate/styrene sulfonate copolymer; and about 0.01 to about 0.5 percent by weight of an emollient mixture comprising isostearic acid, sorbitan oleate, cocoyl hydrolyzed keratin, and less than about 1 percent by weight of water; wherein the composition is a silicone-free, non-aqueous, sprayable composition configured to reduce the drying time of wet hair and has a density of between about 0.7 g/ml to about 0.98 g/ml. ### Claim 2 (depends on 1) The composition of claim 1, wherein the composition further comprises an additive selected from one or more of a fragrance or an essential oil. ### Claim 3 (depends on 1) The composition of claim 1, wherein the composition has a density of about 0.84 g/ml. ### Claim 4 (depends on 1) The composition of claim 1, wherein the composition further comprises at least one cosmetically acceptable additive. ### Claim 5 (depends on 4) The composition of claim 4, further comprising a second cosmetically acceptable additive. ### Claim 6 (depends on 5) The composition of claim 5, wherein the second cosmetically acceptable additive comprises a fragrance. ### Claim 7 (depends on 5) The composition of claim 5, wherein the second cosmetically acceptable additive comprises an essential oil. ### Claim 8 (depends on 5) The composition of claim 5, wherein the second cosmetically acceptable additive comprises a hair conditioning agent. ### Claim 9 (depends on 1) The composition of claim 1, wherein the volatile hydrocarbon mixture consists of about 55 percent by weight of C13- C16 isoparaffin, about 35 percent by weight of C12- C14 isoparaffin, and about 10 percent by weight of C13- C15 alkane. ### Claim 10 A method for reducing the drying time of wet hair, comprising the steps of: applying added water to human hair to obtain wet hair; supplying a silicone-free composition comprising about 90 to about 96 percent by weight of a volatile hydrocarbon mixture consisting of C13- C16isoparaffin, C12- C14isoparaffin; and C13- C15alkane, wherein the volatile hydrocarbon exhibits a vapor pressure of more than 0.2 mm Hg at 25° C. at one atmosphere of pressure or has a boiling point at one atmosphere of less than about 100° C.; about 2 to about 3 percent by weight of ppg-3 benzyl ether myristate; about 0.001 to about 0.01 percent by weight of a sodium laneth 40-maleate/styrene sulfonate copolymer; and about 0.01 to about 0.5 percent by weight of an emollient mixture comprising isostearic acid, sorbitan oleate, cocoyl hydrolyzed keratin, and less than about 1percent by weight of water; wherein the composition is a silicone-free, non-aqueous, sprayable composition configured to reduce the drying time of wet hair and has a density of between about 0.7 g/ml to about 0.98 g/ml; applying the silicone-free composition to the wet hair; applying heat to the wet hair; removing from about 85% to about 100% of the added water; and wherein the silicone-free composition is capable of reducing a drying time of wet hair by about 20 to about 30 percent compared to the drying time of wet hair that was not treated with the silicone-free composition. ### Claim 11 (depends on 10) The method of claim 10, wherein the silicone-free composition further comprises an additive selected from one or more of fragrance or an essential oil.
