TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Product: The aerosol hairspray product further comprises an alcohol selected from ethanol, isopropanol, and mixtures. The compressed gas propellants are selected from air, nitrogen, nitrous oxide, carbon dioxide, and mixtures; preferably air, nitrogen, and mixtures; most preferably nitrogen. The liquefied gas propellants are selected from dimethylether, 1,1-difluoroethane, 1,1,1,2-tetrafluoroethane, pentane, n-butane, iso-butane, propane, trans-1,3,3,3-tetrafluoropropene, and mixtures; preferably dimethylether, 1,1-difluoroethane, and mixtures. The hairstyling formulation comprises 1% or less surfactant, preferably 0.3% or less, by total weight of the hairstyling formulation and propellant. The kinematic viscosity, measured according to standard test DIN EN ISO 3104, of the hairstyling formulation is 1-25 mm2/second, preferably 2-8 mm2/second. The hairstyling formulation comprises a surfactant selected from cationic surfactants, non-ionic surfactants, anionic surfactants, and mixtures. The hairspray product comprises 40-54% of a VOC, by total weight of the hairstyling formulation and propellant. The propellant is a liquefied gas and the pressure inside the container is 1-7 bar, preferably 1.5-5 bar, at 50 degrees C. The surface tension, measured according to standard test ISO 304 at 20 degrees C, of the hairstyling formulation is 20-50 mN/m, preferably 21-mN/m.    TECHNOLOGY FOCUS - POLYMERS - Preferred Product: The product comprises 1-8% of a hairstyling polymer, preferably 2-6% of a hairstyling polymer, by total weight of the hairstyling formulation and propellant. The plastic material is selected from polyolefins, polyesters, polyamide, polyvinylchloride, acrylic, polycarbonates, polyethylene naphthalate, polyethylene terephthalate, polystyrene, polyurethane, and mixtures, more preferably polyethylene terephthalate, polyethylene naphthalate, and mixtures. The hairstyling polymer is selected from octylacrylamide/acrylates/butylaminoethyl methacrylate copolymers, polyquaternium-11 polymers, vinylpyrrolidone/vinylacetate copolymers, and mixtures.
