Compact hairspray product consisting of hairspray concentrate, container and fine spray pump with pre-pressurization

摘要

The invention relates to a compact hair spray product comprising a hair spray concentrate with a viscosity that confers good sprayability, at least one hair-strengthening polymer, an alcoholic solvent for the hair-strengthening polymer, at least one organic solvent additive capable of reducing the viscosity of the concentrate and increasing the vapor pressure of the concentrate and optionally a drying-retarding solvent additive, a pressure-tight and, for the concentrate, diffusion-proof container and a fine-spray pump with a cylinder region made of a material that is resistant to swelling by the organic solvent additive, with a maximum pump lift of 0.12 mL and with pilot pressure buildup.
