Abstract
Abstract Non-aerosol pump hair spray compositions herein are applied as a fine spray mist, without nozzle clogging, and dried rapidly, to provide superior hair holding power. The compositions includes a hair fixative resin which is a copolymer of maleic anhydride and an alkyl vinyl ether, and the ethyl and butyl half-esters thereof, in an amount of between 6 and 20% solids. In suitable embodiments of the invention, the resin is the C2-C4 alkyl half-ester of maleic anhydride and C1-C5 alkyl vinyl ether having a relative viscosity of about 1.20 to 1.35 (1% in ethanol).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
A non-aerosol pump hair spray composition capable of being applied by the user as a fine spray mist which dries rapidly and provides effective hair holding power without nozzle clogging consisting essentially of from about 6 to 20% by weight of a hair fixative resin derived from an ethanol solution of a C 2 -C 4 alkyl which half-ester of a 1:1 alternating copolymer of maleic anhydride and a C 1 -C 5 alkyl vinyl ether, the solution having a relative viscosity of about 1.20 to about 1.35, the carboxyl groups of which are 10 to 100% neutralized with a water soluble base and about 65 to 94% ethanol or aqueous ethanol solvent.
Claim 2
Dependent Claim
113 words
A non-aerosol pump hair spray composition capable of being applied by the user as a fine spray mist which dries rapidly and provides effective hair holding power without nozzle clogging consisting essentially of from about 6 to 20% by weight of a hair fixative resin derived from an ethanol solution of a C 2 -C 4 alkyl which half-ester of a 1:1 alternating copolymer of maleic anhydride and a C 1 -C 5 alkyl vinyl ether, the solution having a relative viscosity of about 1.20 to about 1.35, the carboxyl groups of which are 10 to 100% neutralized with a water soluble base and about 65 to 94% ethanol or aqueous ethanol solvent.
