摘要

A hair spray aerosol system containing a combination of an aerosol can with a valve having a nozzle. The aerosol can contains a composition of which 12-25 wt % is water, 10-26 wt % is an alcoholic phase, and 49-78 wt % is dimethylether. The alcoholic phase contains a film-forming resin making up 3-6 wt % of the total weight of the composition, and the valve and the nozzle have openings designed so that the hair spray outflow rate is 0.5-0.7 g/s. Said aerosol system may be used to dispense hair spray with a class of inflammability no higher than 4 as determined by the Roth apparatus, as well as superior lacquerability.
