Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
In a sprayable hair lacquer composition packaged under pressure in an aerosol container comprising (i) an effective amount of a synthetic polymer for fixing the hair, (ii) an effective amount of an aliphatic alcohol having from 2-4 carbon atoms, (iii) from 0 to 40 weight percent of an auxiliary solvent, (iv) from 0 to 20 weight percent water, and (v) a propellant, the improvement comprising as a propellant a mixture consisting essentially of (a) trifluoromonochloroethane in an amount from 5 to 80 weight percent of said composition and (b) nitrous oxide in an amount sufficient so that the internal pressure of said container is between 3 and 8 bars.
