Claim 9

A hairspray product as claimed in claim 7, wherein the polyoxyethylene has an average molecular weight of at least 4×10 5 .

Claim 10

A hairspray product as claimed in claim 2, wherein the drag reducing agent is a poly(ethyl acrylate) elastomer.

Claim 11

A hairspray product as claimed in claim 1, wherein the propellant is selected from the group consisting of liquefied hydrocarbon propellants, liquefied halogenated hydrocarbon propellants and mixtures thereof.

Claim 12

A hairspray product as claimed in claim 1, wherein the hairspray composition consists essentially of: (A) said hairspray resin in an amount of about 0.4 to about 7.5% by weight of the composition; (B) about 5% to about 99.5% by weight of said solvent for the hairspray resin selected from the group consisting of ethanol, isopropanol, methylene chloride, 2-methoxyethanol, 2-ethoxyethanol, mixtures thereof, and mixtures thereof with water; (C) said drag reducing agent soluble in the solvent for the hairspray resin in an amount effective to enhance the holding power of the hairspray composition, the weight ratio of the hairspray resin to the drag reducing agent being from about 10,000:1 to about 5:1 and the amount of the drag reducing agent being less than about 0.3% by weight of the hairspray composition; and (D) 0 to 90% by weight of said propellant for discharging the hairspray composition from the container.

Claim 13

A hairspray product as claimed in claim 11, wherein the propellant is a liquefied gaseous propellant selected from the group consisting of the liquefied hydrocarbon propellants, liquefied halogenated hydrocarbon propellants and mixtures thereof.

Claim 14

An improved hairspray product consisting of a hairspray composition within a container for spraying the composition onto the hair, said composition consisting essentially of: (A) about 0.4% to about 7.5% by weight of a hairspray resin; (B) about 5% to about 99.5% by weight of a solvent for the resin; and (C) 0% to about 90% by weight of a propellant, the improvement consisting in the inclusion in the hairspray composition, dissolved in said solvent, of a drag reducing agent in an amount effective to enhance the hair-holding power of the hairspray composition, the weight ratio of the hairspray resin to the drag reducing agent being from about 10,000:1 to about 2:1 and the amount of the drag reducing agent being less than about 0.3% by weight of the hairspray composition, said drag reducing agent being a polymer soluble in said solvent and of such a high molecular weight that it has a drag reduction efficiency of at least 2%.

Claim 15

An improved hairspray product consisting of a hairspray composition within a container for spraying the composition onto the hair, said composition consisting essentially of: (A) about 0.4% to about 7.5% by weight of a hairspray resin; (B) about 5% to about 99.5% by weight of a solvent for the resin; and (C) 0% to about 90% by weight of a propellant, the improvement consisting in the inclusion in the hairspray composition, dissolved in said solvent, of a drag reducing agent in an amount effective to enhance the hair-holding power of the hairspray composition, the weight ratio of the hairspray resin to the drag reducing agent being from about 10,000:1 to about 2:1 and the amount of the drag reducing agent being less than about 0.3% by weight of the hairspray composition, said drag reducing agent being a polymer soluble in said solvent and of such a high molecular weight that it has a drag reduction efficiency of at least 2%.
