Abstract
The aqueous-alcoholic hair fixing composition contains from 0.1 to 10 percent by weight of shellac, neutralized from 50 to 100%; from 0.01 to 20 percent by weight of at least one film-forming hair fixing synthetic polymer, advantageously a terpolymer made from octylacrylamide, t-butylamino-ethylmethacrylate and at least two monomers selected from the group consisting of methacrylic acid, esters of acrylic acid and esters of methacrylic acid; from 30 to 70 percent by weight of at least one alcohol containing from 1 to 4 carbon atoms; from 30 to 70 percent by weight water; and, for compositions to be sprayed by means of a propellant, from 15 to 85% by weight of a propellant, advantageously dimethylether, an alkane, N,, N,O or CO,. The combination of the shellac and the synthetic hair fixing polymer causes a synergistic viscosity lowering which advantageously promotes rinsibility without impairing fixing performance.
